MW Windows – Catalog Expansion

Attention! Fenster Components did not purchase, acquire or take over MW Windows! While we sympathize with your frustration, we hope you understand we have NO association with MW and can not field warranty issues. With that said…

We want to help! With MW officially out of business, Fenster Components seeks to offer MW’s former customers a solution to their failing windows. We currently have very few MW replications available and very little information on MW products in general. In order to best serve our customers, knowledge is our priority. We seek sample sashes of any and all wood and wood/clad sash products produced from 1978 to 2010 including the Freedom and Jefferson lines (Freedom primed, Freedom 600/800 wood/clad and Jefferson 100-400 series).

At this time, we have limited replicated sash profiles and replacement sash for MW. We currently only have one ’80s ear primed casement and double hung. Complete assembled sashes are available for all primed units with clear or lowE glass. Knocked down “frame only” sashes are available for cladded units and primed units without glass. Unfortunately replacement cladding is not available at this time, but we’re working on it!

We also put a call out to former MW Windows sales people and distributors that may still have catalogs or specs in their possession. In addition, we seek information relating to MW Windows’ component supply chain, specifically their cladding and weather stripping suppliers. Fenster wants to be your customer, not your competitor!

Fenster Components has been engineering replications of original sash profiles for most major brands since 1999. Our catalog to date boasts over 60 casement and double hung profiles and continues to grow with more nationwide customers seeking solutions to their rotting window issues. Our goal is to connect qualified window professionals to homeowners who need help as efficiently as possible.

    An awning type handle has broken. The name TRUTH is on the handle. We have been pleased with our Pozzi Windows that were installed in 1988. Sorry others have had a problem. Please let us know where we can get a new handle. Thank you. Bill Shearin

    We now have a re-engineered version of two vinyl clad MW casement models in an aluminum clad Quiksash line. Please visit our MW post under “Available Quiksash replications”.

    We have sold our home and two of the windows, once unlatched, fall down at the top and the inspector said that this has to be fixed before closing. Please tell us what we have to do to fix this problem. Unlike the others that are dissatisfied, we have been pleased with our M&W windows. Thanks for getting back to me as soon as possible.

      Betti and Bob, This is usually a very simple fix. Most often, nothing is broken. When the sash just falls under its own weight, that means its not connected the balances. Assuming these are tilt-in units, you will have to tilt-in and remove the lower sash. Then tilt-in the upper sash and remove it. Look at the tracks on the sides of the opening and look for a plastic piece with a hole or cam type slot for the sash tile pin to fit into. The pins on the sash need to fit into that hole in order to be under tension from the balance. That’s the gist of it, I realize its a bit complicated to explain in writing. A window pro or handyman with window experience should be able to correct this for you without the need to purchase new parts.

        I have the same problem with one of my MW double hung vinyl windows. My part (the cam?) that holds the window in the spring is broken. Where can I find replacement parts? Thanks. Susan

        Susan, That is too specific of a part for us. We offer universal fit balance kits which would be the entire track and spring system.

      Mike, Sounds like a good candidate for new jambliners and balances. We stock vinyl compression jambliners for a 1980’s and newer tilt-in window. I’m not sure if these will interchange with your metal liners? You’re welcome to visit our jambliner page on our website,, and see if what we have will work for you.

    I have MW Jefferson double hung wooden windows from around 2005. I have a lower sash with cracked glass (bird hit) and would like to have it repaired. would you like to have it as a model for your replacement line?

    • Posted July 24, 2017 at 11:51 pm | Permalink

      Greg, The best thing to do is just have a local glass company replace the glass for you. You don’t need a whole new sash for that.

    We have MW vinyl double hung windows. Over the years I have replaced a few that lost their seal and clouded. Now I am having a hard time finding them for replacement. Do you have any suggestions?? They have the mullions between the glass.

    • Posted August 29, 2017 at 12:33 pm | Permalink

      Julie, The glass itself is not brand specific meaning it doesn’t have to be MW glass. Any local glass company there in your area should be able to replace that for you.

      We do not Bob, sorry. We’ve looked at producing sill and frame components in the past only to find most repair guys just want to make their own parts.

    My house was built in the 1990s with M&W wood double hung windows. I’ve been able to keep up with the maintenance of the frames. But some of the sash have begun to sag. When I added onto my house a few years ago, I bought M&W Freedom 800 vinyl-clad wood sash windows, and much prefer those sash due to the double latches and no painting. Do you offer replacement sash for the Freedom 800 windows? And can they be retrofitted to the older non-clad wood sash units?

    • Posted November 21, 2017 at 1:40 pm | Permalink

      John, I’m sorry, but we don’t manufacture any double hung models that are vinyl clad. We have our Quiksash aluminum clad sash kit that “may” work for the older units. You would have to be the judge of that. Not knowing exactly what windows you have, I couldn’t make any educated suggestions. If you want to check those out, look at our website, under the double hung sash kit product tab.

    I have composite MW windows made to fit when we remodeled. Two panes have lost their seal. I know a glass company can repair the glass but my grids are mounted inside and outside on the glass. Is there any place I can get the grids. They look to be composite also and stick on. In addition, they look like they need painting on the outside as the finish is chalky. Any suggestions?

    • Posted March 4, 2018 at 8:58 pm | Permalink

      Yikes Dinah, That’s a tough one. Typically your only choice is to re-use the existing grids, but most glass companies don’t want to take the time to remove them and re-apply. We hear that alot. Unfortunately, that’s probably going to be something that was unique to MW and hard to come by, especially it they are composite. You’re best bet is to convince a glass company to re-use them and be prepared for the labor bill!

    • Posted March 12, 2018 at 12:13 pm | Permalink

      Lee, I’m sorry, but we don’t sell hardware. MW should probably have used TRUTH brand hardware. If you do a search, there are several online TRUTH dealers.

    I need to replace two MW wood double hung Jefferson style windows due to cloudy windows. At $100 per pane, it seems more reasonable to replace the entire sash. Would this company be able to provide entire sashes?

      Anne, I’m sorry we do not.

    I own MW casement windows. The were installed in 1993. Wood interior and exterior. The exterior bottom of the Sash is beginning to rot. Do you have any idea what the model could be? Would you recommend a Sash kit or replacement? The frame is in excellent shape and most of the window is perfect. The glass seals well, and the hinges and weather stripping are new. The Sash frame is the only part that’s compromised. Thanks

    • Posted September 4, 2018 at 11:28 pm | Permalink

      David, Really hard to speculate on the model just based on the year. MW could have had any number of models available at the time. It’s most difficult part of our industry and what we have to contend with as a company. I have other manufacturers that sold the same window profile under multiple brand names…all at the same time. Some companies had interchangeable clad/primed units, other were completely different. Identification is a visual thing. I just need to see what we’re dealing with to make an attempt to identify it.

      To your other question. I NEVER recommend the rebuild kit unless I don’t have a better alternative. You have a 25 year old piece of glass that only had a 20 year life span at the time. There’s no point to try and save that if you have any expectation of longevity. You get no warranty with the rebuild kit and no guarantee your glass with survive the project.

    I have MW double hung windows about 25 years old. The exterior sash is rotting on one of my windows. Wondering if the Sash replacement kit will work for this application. If so how do you measure the replacement Jamb liners to get the sill angle correct. Thanks

    • Posted September 25, 2018 at 12:01 pm | Permalink

      Hi Kelly, Don’t over think the sill angle thing. 14/15 degree is the industry standard. Which is how our liner kits come. If you pull a height to the long point at 1/4 or 3/8 of an inch, our standard heights will work for you.

    I need to replace the crank mechanism for an MW casement window. Any suggestions for replacement hardware? The rest of the wood window and glass seem fine. Installed in new construction in 2000. Thanks

    • Posted October 19, 2018 at 12:47 pm | Permalink

      There are several online window hardware companies out there. The trick is to not search for MW. Most window brands from the era used TRUTH brand hardware.

    I have MW windows with bottom tilt. The weather strip or seal at the bottom of the lower window is deteriorating, due to the heat and they are 17 years old. Do you sell the replacement stripping? If so what item is it?

      Pat, We don’t have brand specific parts necessarily, but if it’s a bulb seal or similar to industry standard, we may be able to get you something that will work. You can contact my parts salesperson at:

    It appears we have MW windows in a pre-fab home 16 years old. We have 2 window in 3 rooms on the second floor side by side. On the outside, Between them, there is a vertical piece of wood with grooves that a vinyl or plastic cover with tracks that slip into the grooves. I have no idea what they are called and the ones we have are broken. They are about 5 feet long and 3-4 inches wide with 2 tracks. They slip in under a cover at the top. I do not know what they are or where to find them. It sounds like your company took over MW and I am wondering if you either have these parts or know what they are called so I can find them before water gets down under the windows.

    • Posted April 14, 2020 at 12:15 pm | Permalink

      Thanks for the comment Don, First off, no, we didn’t take over MW. We represent 20 some odd different window brands. If I was a billionaire that could have bought 20 window companies I sure as heck wouldn’t be building sashes for a living! If I’m understanding your explanation, it sounds like a parting stop. Unfortunately we do not make any frame parts. Surprisingly being in the line of business we are, we get very little request for parts like this. Most field carpenters prefer to make their own parts rather than buy something pre-made. That might be your best option in this case.

    I recently posted a comment which apparently never was shown on your site requesting information on MW double hung sash windows installed in our home around 2003. Many of the larger windows has sashes that would not remain open or fell down when unlocked. I was able to reinstated all of those sashes back onto their spring balancer assemblies for the exception of one upper sash that, although reattached, drops an inch or two when unlocked. I need replacement parts for this window along with instructions for installation. Can you provide me with that or tell me where I can obtain those parts? The information found on upper frame member is as follows: NFRC 100/200, Code: PAT (VA), Series VWDH, and MST 3856. Window width is 38 inches in width and 60 inches high.

      Jeff, Sorry I thought I responded to this? We’re not on the hardware side of things. We don’t carry anything you are looking for. You might do a Google search for window balance parts.

  • Posted October 18, 2020 at 6:51 pm | Permalink

    Hello. I’ve got MW casement windows circa 2005. Two of the crank components have broken. Would you be able to provide any sort of replacement?
