How to Measure
Follow these steps:
- Casement sashes: From the EXTERIOR side, measure the width of the sash from edge to edge, and the height of the sash from top edge to the bottom edge.
- Do not measure the glass opening, do not include weatherstripping in your edge measurement, do not provide the frame size or opening.
- For some models, we may ask for a sash "thickness". This is the dimension from inside face to outside face, NOT the width of the cladding face.
- 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.
- Double hung sash kits: We only require 2 measurements to size the kit for the opening. Measure the width of the sashes. Both sash widths will be the same.
- Measure the height of the jambliner to the long point which is the outer edge that follows the slope of the sill. All kits will be made to industry standard heights as shown on the sizing chart on the Quiksash product page.
- We accept edge to edge, net sash sizes only.
- NO GLASS OPENINGS PLEASE.
- Take all measurements from the exterior side of the sash.
- Do NOT adjust your measurements for fit. Our standard practice is to undersize sashes by 1/16" or more depending on our installation experience.
- Heights of double hung sashes is NOT required. Our sashes are designed to fit the opening, NOT match your original sash heights.

I don't see what I need
The window industry is very complicated. Consider the reality that the windows you have in your home are not the only model of window ever made! The brands and models we have replicated are representative of over 40 years of window manufacturing. It is imperative we perform our due diligence to get every detail correct. The more detailed information you can provide us, the better equipped we will be to support you in your window needs. The following are a few tips to get you started.
First, did you search the sash profile catalog and product categories to see what we have available? We have merely a fraction of the 100’s of possible makes and models produced over the last 40 years. Just knowing the brand, maybe narrows it down to eight or ten. We need you to tell us, if we have what you need.
Second, are you having trouble understanding what information we need? We have added chat bots and check lists to our site to better assist you in navigating our website, along with helpful articles and conversations in our blog with folks having the same window issues as you. In the end, there is simply no way around the technical information we MUST have in order to produce a product. You may want to get a professional involved to help you if you are still having trouble.
Third, do you find yourself asking, "what's next"? Our easy 4 step process shown right on our home page walks you through our whole process.
Fourth, are you unsure about what you are getting? We get so many questions about sash specification. YES! Sashes come with weatherstripping on them. The specifications of every sash product along with detailed explanations are prominently displayed on each product page. Please take some time to review this information before contacting us with simple questions that have already been answered for you.
Finally, maybe we just don't have it! So much of our customer service energy goes to customers asking about something we don't sell. Quite frankly, if you can't find it on the website, it's not there. What is displayed on the site, is all we have available. Our most common "not for sale" items; We don't sell screens, we don't sell wood grills, we don't sell replacement glass, we don't sell incredibly specific little plastic parts, and most of our components are not brand specific. Cladding and weatherstripping for example is very universal in nature. We do not carry any original OEM parts from the manufacturer.
