How to Repair a Wooden Window Sash

Wood windows add a classic aesthetic to your home. Properly maintained, they can look great for years. You can paint them one color, and years down the line, repaint to match any changes to your home’s exterior and interior, giving you more flexibility than you would have with other materials, like vinyl.

But eventually, wood window sashes may become damaged or degrade, especially in older, historic homes. As a natural material exposed to the elements, over time your window sashes can chip and eventually rot, even with regular maintenance. Sash window repair involves attention to detail, but it is something you can manage on your own with patience and knowledge.

If you’re active in inspecting and keeping your window sashes looking good, it’s possible that all you’ll need is a few spot repairs to fix chips and splits in the wood. You can repair these surface issues with a sash repair kit. These sash window repairs will also keep out water and pests that can lead to more rot. 

If, however, you don’t check your wood window sashes for damage regularly, rot can set in, which will then require a full or partial wood window sash replacement.

Depending on the extent of your sash window repair, you may be able to get it done without removing the panes from the sash. If you’re only patching a small crack in the sash, you may be able to sand it, fill it in with epoxy, sand some more and paint.

If, however, the damage is more extensive, you may need to take the whole assembly apart to repair or replace window parts.

Below are the steps to replacing an old-style wood window sash, the kind that is typically seen in homes pre-1970s. While we understand you may want to stay true to your older home’s windows, it’s important to realize that they could be costing you money on your energy bills. Old windows, even ones well maintained or recently repaired, don’t feature the same energy efficiency and function as newer windows. 

If you want to save money on your energy bill and avoid the hassle of continuously repairing your window sashes, you should consider replacing the entire window. Companies like Fenster USA offer a wide variety of wooden windows, so you are sure to be able to find a new window in the same style as your old window. You’ll get all the beauty of your old style with all the benefits of modern window technology.

Step 1: Remove the Window Sash From the Frame

If you’re removing parts of the wooden window sash, you’ll need to take the sash out from the frame. To do so, unscrew the stops, which are the two blocks that keep the lower sash from sliding up too high, or parting beads, which hold the upper sash in place. Remove any cords or chains and tie them off to keep them from retracting if they’re weighted.

Step 2: Release the Glass

Glass panes in a wood window sash are held in place with glazing compound or putty. While durable, glazing compound will crack and split over time. To release the glass from the sash, you’ll need a heat gun and chisel. Gently heat the glazing compound with the heat gun and then scrape it off with the chisel, taking care not to scratch the glass.

Once the glazing compound has been removed, you can gently pry off the glass. If you’re working with more than one pane, make sure you label them so you know where they fit when you’re done with your repair.

Step 3: Re-Inspect the Sash

If you’ve gone to the trouble of taking the glass out of your sash, it’s a good idea to go ahead and do another thorough inspection of the whole sash. You’ll be able to identify any previously-hidden places where the wood may have started to rot or where old glue, weather stripping or hardware has also degraded. While this may be an extra step, it will save you from having to do even more repairs in the future.

Step 4: Repair Damaged Joints and Chips

Clean out the joints to remove any crumbling epoxy or rotting wood. Sand down any chipped areas. Prepare your fresh epoxy or wood filler according to the manufacturer’s specifications, and apply using a knife. Let it cure and sand down. 


Step 4: Take Apart the Sash and Build Replacement

If you need to replace some or all of the sash, carefully take apart the old sash. Keep the existing parts, as you’ll need them to mark where any hardware goes as you assemble the new wood window parts.

Window sash replacement kits can be purchased to make your window repair project simpler. They are pre-cut to the dimensions of your existing sash and can be built to match a number of models from older window manufacturers, so the joints and grooves will fit with your existing parts if you aren’t replacing the entire sash.

Assemble your wood window sash replacement. Make sure all your joints are flush and smooth so the panes will fit properly and the completed sash won’t catch on the tracks. Use the older sash parts you kept so you can measure and mark the location of any hardware like hinges and screw them in place.

Step 5: Prime the Sash

Priming is an important step. Sealing the wood will protect it for years and save you the work of having to do additional repairs before you really need to. Priming also means the wood won’t suck necessary oils out of the glazing compound, which could cause it to crack and fail prematurely.

Step 6: Bed the Glass

Use glazing compound to secure the glass back into place in the repaired sash. Don’t be afraid to be liberal with the compound; you’ll wind up cutting most it off, but you want to make sure it’s been fully and evenly applied to the sash rabbet. Gently press the glass in place to make sure the sash is filled, and then cut away the excess compound.

Step 7: Set the Points

Points are set into the reassembled sash to fully hold the panes in place. They can be applied with a gun or by hand. Depending on the size of your panes, you may need more than one on each side. Points should not be more than 10-12 inches apart.

Step 8: Tool the Putty

Apply another layer of putty on the sash and outside of the glass. Don’t worry too much about making it look clean at first; the goal is simply to apply an even layer all the way around the pane. Pack the putty into place with the edge of the knife. Apply a second layer, and use the knife blade to create a smooth and thin bevel all the way around. Let it cure fully before painting.

Step 9: Paint

Once your window repairs and replacement parts are fully cured, you can paint and stain as desired to match your home’s interior and exterior.

Step 10: Rehang the Sash

Before you rehang your repaired wood window, add weatherstripping or replace old weatherstripping. This protects your home and your window. Lubricate the tracks. Reattach cords or chains and slide the sash back into place. Replace stops and parting beads.

Ready to Start?

Repairing a wood window sash sounds complicated, but the actual step-by-step process is not overly complex. With the right wood window replacement parts and a little patience, you can repair your own windows and have them back in place in no time.

What Does Window Replacement Cost?

Windows are often one of the most overlooked design features of a house. But old and dated-looking windows can quickly hurt your property value and damaged or deteriorating windows can hurt your energy efficiency and result in issues like condensation and mold growth.

As a result, homeowners may replace their windows for a number of different reasons. These can include:

  • Replacement or repair after damage
  • Updating the look of your home
  • Improving energy efficiency and reducing utility costs

While there are potential cost savings, or an opportunity to make more money through increased property value, undertaking a window replacement can be expensive, particularly if you’re dealing with a whole room or a whole house.

How much window replacement costs will depend on a number of factors, such as:

  • Are you replacing the glass, sash, frame or the whole unit?
  • What materials will you use?
  • How old are your windows and are replacement parts available?

Depending on the age of your windows and how long you’ve been in your home, it’s possible that you may not have all of this information available. Because well-manufactured and properly installed windows can last for decades, they may have been in your home longer than you’ve owned it, making it hard to identify important details like the window make and model.

As a result, it’s often easy for many contractors to tell you that the full window needs to be replaced, and that replacement parts aren’t available for older windows, particularly wood ones. Or else they might say the cost of wood window replacement is too high.

It’s true that, on paper anyway, the starting cost of a new wood window may be more expensive than a vinyl one. But wood window repair may be a more available option that you’d initially think, and there’s more to window replacement cost than what the frame is made of.

Here are some factors to consider when calculating the cost of replacement:

  • Replacement glass: If you’re replacing your windows for energy efficiency purposes, not because they’re damaged, then you may need to only replace the glass. A single pane window could cost as little as $47, but isn’t very energy efficient. A low-E or triple pane window will cost $110 to $128 dollars, while a double pane window is about $96.
  • Window style: A big bay window may be a great feature, but bay window replacement costs can be as high as $3,500. By comparison, a classic wood sash window can be as little as $300.
  • Materials: Yes, wood is more expensive than vinyl, but it’s still generally less expensive than steel or fiberglass. And replacement wood window sashes can come in a variety of colors and can be painted or stained to match existing fixtures, shelves or cabinets in your home, giving you greater design flexibility.
  • Labor: Labor rates vary across the United States and can add $100 to $200 or more per window. When you’re speaking with contractors, ask them about which suppliers they use for window replacement, what experience they have with wood window repair and how they source parts to repair and replace older wood windows.

So which window manufacturer should you choose when looking for wood replacement windows?

Pella and Andersen are the leading manufacturers of replacement windows in the United States. When talking to contractors about window replacements and costs, many will recommend either Pella or Andersen products.  

Both companies offer four different lines of wood windows. Prices for Pella range from $170 for a 450 Series/ProLine wood window to $1,800 for the Architect Series Reserve line.

For Andersen, the base price for a 200 Series wood window is $265 and can extend to $1,650 for their Architectural Collection A-Series windows.

By comparison, Fenster’s wood window repair and replacement sashes are priced affordably and are compatible with a number of older window manufacturers including:

  • BiltBest
  • Caradco
  • Craftline
  • Hurd
  • Kolbe
  • MW
  • Malta
  • Norandex
  • Norco
  • Pozzi
  • Rockwell
  • Sealrite
  • Semco
  • SNE
  • Weathervane
  • Windsor

If you’re not sure what type of window you have, tips for identifying individual models can be found here.

Fenster’s Quiksash Clad/Wood Casement Sashes are guaranteed to work and perform at a much higher level than the original window by deleting engineering flaws like boot glazing and exterior glazing stops. And with a starting price of $345, these sashes are priced comparably to the leading brands. Similarly, our Double Hung Sash Kits start at $399, making them competitively priced.

And since all Fenster sashes come standard with low-E glass and weatherstripping, your home will benefit from added energy savings.

To order replacement sashes, you’ll need a few measurements:

  1. From outside the window, measure the width of the sash from outside edge to outside edge, and the height of the sash from the top edge to the bottom edge.
  2. Do not measure the glass opening or weatherstripping.
  3. Some wood sashes may bow over time. You should measure in different places and use the most common measurement you get.
  4. On cladded sashes, it is okay to measure from edge to edge of the cladding. We will size the wood frame to accept the cladding.
  5. To measure double hung sashes, it is sometimes easier to tilt the sash toward you inside the house to get a better measurement of the exterior side.
  6. Enter your width and height in the corresponding size ranges on the sash quote section to get your quote. These exact measurements will be required at the order stage.

You’ll also need to know what kind of window you have:

  • Stationary windows are the simplest. A single fixed pane of glass in a sash.
  • Single hung windows feature two panes of glass in separate sashes, where one pane is fixed and other is on a track so it can be slid up and down.
  • A double hung window is similar to a single hung, but both panes are able to slide.
  • Casement and tilt windows don’t slide like hung windows but open on a hinge or with a crank.
  • Awning windows hinge horizontally, usually from the top, to let in air.
  • Picture windows are fixed, but typically larger than a standard stationary window, to let in more light.
  • Sliding windows, like sliding doors, slide on a horizontal track, rather than hung windows which slide vertically.

Hail Damaged Windows

Hail damaged windows can be repaired without full window replacement!  Until recently victims of hail damage had only one option to restore their windows to pre-storm condition.  That included the very costly and invasive project of window replacement.

Full Replacement Pit-falls

Consider for a moment the impact a project of that scope can have on your home and your family.

  • An aluminum clad window is secured in the wall by a nailing flange on the exterior side of the house wall.  If your home is brick, stone, or stucco, it is impossible to remove the window frame without damaging the surrounding material.  Picture the resulting appearance of your home after that brick, stone, or stucco has been patched back in around the new window.
  • In many cases, a contractor may elect to not cut away the exterior material to remove the window.  But wait, I just said that was the only way to do it right?  Yes, but that’s not how its always done.   Some contractors will remove the nailing flange and screw the new frame into the opening through the sides.  Yes, it holds the frame in place.  Now let’s talk about sealing, flashing, and water leaks.  There is no way to wrap around the new frame and seal it to the wall using this technique.  Good luck with that!
  • What happens on the interior with a full window replacement?  Drywall damage, painting, colors not matching, blinds not fitting, dust, mess…for days and days, and days.  Your ultimate satisfaction comes down to the quality of contractors working in your home, their attention to detail, and respect for you and your home.  Still keep in mind, the hail damage wasn’t inside your house, but now you have a major mess on your hands!
  • I’ll save poor contractor service, quality, communication, integrity, and follow-up for another post.

A Better Idea

Fenster has a better way to repair hail damaged windows.  Removing the entire window is no longer necessary.  In most cases, hail damage only occurs on the face of the sash panel.  The sash is the glass and frame surrounding the glass that you open and close.  On most aluminum clad windows, there is very little surface of the frame exposed and is often protected by the surrounding exterior finishes requiring only the sash panel by replaced.  Not the whole window!






Our Quiksash for hail damaged windows is an after-market sash replacement system engineered to retro fit directly into the existing window frame without modification and without affecting the fit, form or function of the window.   Fenster guarantees same like, kind, and quality on every Quiksash model to closely resemble the original sash and not significantly change the appearance of the window in any way.  When Quiksash is used on a home 10 years or older, the quality and efficiency of glass technology will exceed the original window actually upgrading the window from its original performance.

This is the first of a multi-part series on our Quiksash for hail damaged windows products and their advantages over full replacement.  Stay tuned for more.  In the meantime, please visit our website, for more information about Quiksash and our other window repair products.

sealrite clad samplesealrite clad corner profile





Many clad wood windows look similar from the exterior.  Exactly why the Fenster Quiksash blends perfectly with many brands.  Sealrite Windows have a couple unique features to help identify them.  The vertical edge, or stile of the sash has a prominent rounded interior edge as seen in the photo above.  Also, the top and bottom of the sash, called the rail, has a pronounced rib that sticks out from the edge, also seen in the photo.

Fenster Quiksash is a simple and cost effective way to solve glass seal failure and hail damaged sealrite windows when compared to a full replacement window.  You now have options to repair only damaged windows with a direct fit after-market product avoiding a high priced full replacement or the disappointing switch to vinyl.

Window repair-Why it works

Window Repair works for obvious reasons.  A new window salesman won’t tell you why.  For as many years as I’ve been in business, I’ve had folks ask, “How do I know this works?”  Well, somehow we’ve been making window parts for over fifteen years now, what do you think?

rockwell 2007

rockwell 2007 after


The obvious isn’t so obvious if you don’t have a “repair” mind-set.  If you’re a consumer conditioned to the modern disposable, instant gratification society, well then it makes perfect sense to tear out windows and start over.  From my perspective, it makes much more sense to repair, or what we like to call “replacement innovation” than to replacement the old with “new” with the expectation that the “new” is better.  Maybe?  The thought of window parts and pieces can be confusing.  We’re going to fix that later.  For now, let’s walk through a brief list of thought provokers and you decide.

  1. It’s cheaper!  I refuse to argue with the $189.00 vinyl window guys.  That is a sales pitch to get in the door.  No salesman will sell you a $189 window.  Obviously markets vary across the country, but a reputable, professional window company is going to run in the $700 per opening range for new vinyl windows.  A far cry from the billboard price.
  2. Window repair is specific.  You only address the windows that are problematic, not the whole the house.  In my experience, most homes have 3-4 windows at any one time with damage.  Window for window, a replacement sash approaches the cost of the vinyl.  Now consider the cost of just replacing the three or four, not the whole house.
  3. Like kind and quality.  Did your neighbor with the brown house that put one bright white vinyl window in the side of it think about what their house was going to look like?  The idea of window repair or “replacement innovation” is to return the original window to original condition.  This also means keeping all of your windows matching.
  4. Less invasive.  Window replacement is a major remodeling project.  Disregard the “vinyl insert” type of product.  That is a whole other animal and soap box issue for me.  I’m talking a direct replacement of a full frame window. Window repair doesn’t cause drywall damage, woodwork damage, require new window treatments, or disrupt sealing or building envelope surfaces.
  5. Convenience.  Window repair is faster.  Our typical six week lead time is a fraction of the time you will wait for a new batch of windows from the factory.  Installation time is also a fraction of new window replacement with less mess and interference to your life and schedule.
  6. DIY is possible.  Save even more by doing it yourself.  Repairing rotten wood frames is experienced carpenter work, not sashes and hardware.  If you can turn a screwdriver, then doing this work yourself is possible.

Our new goal for 2016 is to bring window repair to DIY’er status.  Through more instructional blog posts and a new video series, I will be walking you through the basic installation steps of many of our popular window repair products in an effort to bring our concept of “replacement innovation” to the forefront of the window industry to create a new option category for the window consumer.

Window repair improves energy efficiency

Looking to improve the energy efficiency of your windows?  Window replacement isn’t always the answer.  Some simple cost saving improvements can be made to your existing wood windows to improve their efficiency without replacing the whole window.





There are two basic styles of weatherstripping that come in many shapes and colors, but serve two simple purposes.  A bulb type weatherstrip is used to provide the thermal seal between the sash and the window frame.  You would typically find this type of weatherstripping along the edge of the frame on a casement window where the sash meets the frame when closed.  A bulb is also used on the top and bottom edges of double hung windows where the sash meets the sill and head jamb.  The other general style of weatherstripping is called a leaf type seal.  You find these typically on the perimeter of a casement sash.  The misconception is this serves as a thermal barrier.  The leaf seal on a casement is referred to as the storm shield.  This is meant to prevent excess wind driven rain, inserts and debris from getting in around the sash.  It doesn’t provide any significant thermal value.

By replacing the bulb type on your windows, you can cut down on drafts around the sash.  Many windows were supplied with a hollow vinyl bulb that flattens out over time.  By simply replacing this with new, it will return the seal to its original performance.  For an even better seal, you can upgrade from the hollow bulb to a foam filled bulb that will take up more space in the gap and create a tighter seal between the jamb/sill and the sash.




A common issue with aging windows is seal failure.  This is the breakdown of sealant around the perimeter of the glass unit allowing air and moisture to enter in between the panes of glass.  The common misconception here is that there is some sort of gas between the panes of glass.  This is not the case with most windows older than 10 years or so.  The addition of argon or krypton gas is relatively new and still and expensive upgrade.  Prior to that, there is simply dead airspace between the panes of glass creating the thermal barrier.  A couple things to keep in mind when having glass replaced.  Glass is not brand specific.  The IGU, or insulated glass unit is a separate, pre-sealed component of the window that can be removed and replaced with any type of glass unit provided it is the same size and thickness.  This is your opportunity to upgrade the existing glass to newer technology to increase the energy efficiency of your existing windows.  With the evolution of lowE coatings and cool edge spacer technology, you could increase the efficiency of your existing windows by 20-30% without replacing anything but the glass…which had failed and needed to be replaced anyway! Most new glass comes with a warranty too!

When considering upgrading your glass, keep these things in mind.  One, upgrading just one piece of glass on a bank of windows won’t do anything.  You need to replace all of the glass in a set of windows, and even a step further, all of the glass in the room to see any significant improvement.  Also, keep in mind, glass with a lowE coating will have a slight tint compared to basic clear glass.  Now its not “tinted”. By itself you wouldn’t call LowE glass tinted, but next to a window with clear glass on a sunny day, you will notice a difference.  Avoid this by upgrading glass in windows that are directly side by side.  Finally, for the best results, upgrading all of the glass on the south and west exposures of the house is the best way to see and feel an increase in energy efficiency.

If energy efficiency is your primary goal, but your budget isn’t ready for new windows, consider these cost effective window repair ideas to upgrade the windows you have for a fraction of the cost of all new.  There’s an old saying, “They just don’t make them like they used to.”  This is true in many respects.  New window companies push the energy efficiency of their windows.  What they don’t tell you is the technology is in the glass, not the rest of the window.  Its my humble opinion that a traditional wood window is far more attractive and warm feeling in a home than white plastic.  If you had the opportunity to put the same glass technology in your wood window that comes in the new vinyl one, what would you choose?

Window repair, not an emergency

Window repair is not an emergency folks!  It took 20 years for your windows to rot.  A couple more weeks won’t hurt anything.

The first thing about the window industry is; it’s not in a hurry.  So from a supply stand point, we wait sometimes 5-6 weeks just to get raw materials in.  Now we do a better job than most managing this, but special orders take extra time.  Also, during high volume times of the year, suppliers are busy too.  We all struggle to keep up.  What I will ask is, “Can anyone do it faster?”  Most major window companies take 8-12 weeks to get you a stock item.  We’re making this stuff from scratch and still getting it out usually in 6 weeks or less!

Time is certainly of the essence, but that depends on the time of year.  We understand, summer is over, the weather is turning, and so is your attention to your home to prepare it for winter.  What we need customers to understand is EVERYONE ELSE has the same idea!

What’s wrong with the rest of the year?  The summer is a great time of year for window repair.  Its dry, warm.  In the spring, flowers are blooming, its new, its fresh, why not make your windows feel the same?  It doesn’t snow everywhere in the winter.  Where’s our southern friends in January and February?

Why isn’t anyone in a hurry in the winter we wonder?  I think its more about top of mind.  Not many homeowners take time to inspect their windows regularly.  Usually its a painter pointing out window repair needs during a paint job.  We get it.  You’re suddenly made aware of this issue, you got the painter there, its one more problem to deal with between soccer and choir practice…whatever.  Its a hassle you need to have go away, right away.

The thing to consider is not the lead time, but the finished product.  When you open that box to begin your window repair, are you expecting something that looks like it got done in a hurry?  Of course not.  You still expect a quality product.  Fenster only does things one way; The Right Way.  The Right Way way takes time.  The Right Way way takes more time August through October because so many customers wait until this time to get it The Right Way.

We certainly appreciate all of the window repair business, anytime of year we can get it!  We thank you!  We ask for a little more patience this time of year to get your order done, what?  The Right Way.  Lead times in the fall can run 6-8 weeks.  There are 9 more months of the year folks!  If you want something in a week, call us January!

The vinyl clad double hung shown here is a boot glazed window with a sharply mitered corner on the lower sash.  Most models had a torx screw as the lower tilt pin and a helicopter pin screwed in through the cladding on the upper.  This window was produced for many years from the mid 80’s through the mid 2000’s.  All looked the same, but with differences of note.  Earlier models were boot glazed with two different glass thicknesses.  The newer is a wet glazed sash with an interior glass stop.  The Fenster after-market unit will match the newer model with the interior glass stop, but WILL fit the older models since the sash profiles otherwise were not altered.  The Fenster part number for a complete cladded sash is MTDH250-C (upper or lower).

We are currently stocking WHITE Malta window cladding for both models.  Beige/sand can be special ordered with a minimum quantity of 10 sash.  Place and order request today at or email
