Our Historic Window Restoration Process

Restoring historic windows to their former glory is a meticulous and specialized process that requires the utmost care and expertise. Make sure you choose the experts! At Apex Window Werks, we follow a comprehensive restoration process to ensure that your historic windows maintain their authenticity and charm.

Our process typically includes the following steps:

To maintain historical accuracy, we research to understand the architectural style and materials used during the time your windows were originally installed. This research ensures that our restoration aligns with the historical context of your property.

3. Removal and Transportation

If necessary, we carefully remove the windows from your property. We take great care during removal to avoid any further damage. Once removed, the windows are safely transported to our restoration facility.

4. Cleaning and Stripping

We begin by cleaning the windows and removing years of dirt, grime, and old paint. Stripping the windows down to their bare wood surfaces is often necessary to start with a clean canvas.

5. Wood Repair and Replacement

Damaged or rotting wood components are repaired or replaced with matching materials to maintain the original look. This step may involve repairing sashes, frames, or muntins.

6. Glass Restoration

If the original glass can be salvaged, we carefully restore it. If not, we source historically accurate glass to replace any damaged or broken panes. We choose glass to match the era when your windows were first installed.

7. Glazing and Weatherproofing

We apply traditional glazing compounds to secure the glass and ensure a weathertight seal. Proper glazing is essential for the long-term durability of the windows.

8. Reassembly and Refinishing

Once all components are repaired or replaced, we reassemble the windows, paying close attention to proper alignment and fit. We then refinish the windows, matching the original color and style to maintain historical accuracy.

9. Testing and Adjustment

Before reinstalling the windows, we test their functionality. This includes ensuring that they open and close smoothly and that hardware, such as pulleys and locks, are in working order. Any necessary adjustments are made.

10. Reinstallation

We carefully reinstall the restored windows back into your property. During reinstallation, we pay special attention to ensuring that they are level and properly sealed to prevent drafts and water infiltration.

11. Final Inspection

Words from
Our Clients

Great value compared to replacing all windows. Andersen Renewal quoted me $75k plus an addition $25k for dryvit work on 16 windows they told me needed complete replacement. It turns out only the lower sashes were rotted and only 2 window pains needed replacement on over 20 windows and 44 sashes. Apex did all the work for less than $20k in 3 days and the windows now look and operate like new. Huge savings.My only negative is that about a week after install a metal plate fell off from around the outside of one window. Apex came out immediately and repaired it....checking all the windows to make certain they were effectively caulked..I would recommend anyone with aging wood windows to give APEX a chance. They can save you a fortune.

Chris Ras

Had restoration work done on two large picture windows. Apex was very professional and easy to work with. They returned calls within reasonable time, the estimate Nate gave was solid, appointment times were honored, the repair crew of Marcelino and Dave did an excellent job replacing and finishing the rotted wood. They were pleasant, quick and neat. I recommend Apex Window Werks! P.S. Thanks to the office staff too!


We hired Apex Window Werks to repair two of our wood casement windows after talking to 3 different contractors. All the contractors indicated our windows could not be repaired, and needed replacement. Apex provided a quote we were looking for to repair the windows. They were abble to remove rotten spots in two windows, fabricate replacement parts, and then install the new parts. The work is high quality, and I am completely satisfied.

Jayden Montgomery

Service technicians were polite, and professional. They removed damaged parts of the window, cut new pieces to fit, stained the wood and installed them nicely. The team cleaned up as if they were never there. I would recommend Apex Window Works for your window repair.

Glenn Kaupert

Apex Window Werks was contacted to replace my wood windows. They did not attempt to sell me something I did not ask for. Every other company did. Apex was professional, timely and the price was reasonable. I would use Apex again for my next project and I highly recommend this company to replace or repair your wood windows.

Kim Nalls

The gentlemen that performed my service were on time, professional and I am so happy with their work. I highly recommend your services.

Clara Williams

I was thrilled that Apex window works, had the right parts, and was able to come right out and repair my window on site. They were very prompt, and they saved me quite a bit of money over the replacement quote I got from another window company that didn’t do repairs.

Eric Hoffhines

Apex was fast, courteous and very competent. You’re price was lower than your competitors and you installed the window the next day, while other competitors were quoting 10 days delay.
