Scott DeWitt is the absolute 100% reason for my review being 5 stars instead of 3. He was a great installer, timely, respectful, genuine, and did the job right. Everything else unrelated to his work wasn’t all that impressive. Thanks Scott for the top tier work.

Had a glass block window put in my basement crawl space. They did a great job and they were quick and efficient. Would have them out anytime.

We discovered this company while visiting relatives in Ohio. Since our initial contact to replace two sets of French Doors, the entire process has been exceptional, simple, and the products are of the highest quality (while not the priciest in the market!) No hesitation to recommend this company to anyone.

Keith came out to review and quote our project. He was timely and informative. Then Thomas came out to install the windows - he was early (AWESOME), polite, completed the task quickly, and cleaned up after himself. We are happy with our windows too - they look great. We'll definitely work with this team again on our future window projects.

No matter what style your windows are, condensation caused window rot is one of the problems you must address immediately. After all, if your window starts rotting, it can cause numerous problems for you, such as energy efficiency problems or water leaks. Thankfully, even if your windows have some rot, you can still fix them.

Step 1: Scrape and Drill

One of the first things you should do when repairing window rot is to scrape the rotten wood away with a chisel. Once you’ve accomplished that, you have to drill a series of holes throughout the rotted area, one inch apart. If the wood is still damp afterwards, you’ll have to wait more than a week to let it dry fully.

Step 2: Add Epoxy

Once the wood is dry, you now have to add epoxy to the window. Once the mixture is ready, put it in a squeeze bottle, and squirt the epoxy into the holes you drilled. After five minutes, the epoxy should soak into the wood. Repeat the process once more when it does until the wood is saturated with epoxy. Afterwards, you have to let the epoxy cure for a week.

Step 3: Add Wood Filler

When the epoxy finishes curing, you’ll now have to add epoxy wood filler to the problematic vinyl or egress windows. Simply scoop the filler onto a putty knife, and scrape it into the holes to completely fill them as much as possible. Once the holes are filled, cover the remaining rotted-out areas with epoxy. You’ll have to shape the filler into the windows frame’s approximate dimensions as well. Afterwards, let it dry for at least four hours (warm weather) or overnight (cold weather)

Step 4: Sanding and Applying Primer and Paint

After the filler has dried out, you can shave off any excess filler with rasps and sandpaper until it’s in your desired shape. Within three days, you’ll have to apply primer and paint to your window. If you must, check the manufacturer’s instructions to know how you can properly apply the primer and paint.
