"From the first interview our sales consultant through the post installation follow-up, we were very happy with the service and work that Excel Windows provided. Sales: We found Matt, our sales rep for Excel, to be friendly, knowledgeable and very responsive to the many questions we had for our large project. Matt walked us through the process of selecting an experienced window installer and quality window, communicating through email, phone and multiple in-person visits, and made sure we were comfortable with Excel’s products and assuring us that we would be receiving the level of service and product quality we desired. Matt always made himself available to answer questions, even after the project moved out of the sales phase and into the installation phase. Installation: During construction, Egor and his partner were very professional and completed the work as cleanly as possible. Of the ~28 windows we had replaced, only a couple required minor paint touchups to the trim and no window trim needed to be replaced. The trim around the sliding doors had to be replaced to allow for door installation, which we were informed about during the sales process. Excel had to be called back out once to fix a piece of warped trim work, but not a major issue. The one thing I wished I had done was ask whether I could buy pre-primed white trim and paint it in advance of Excel replacing the trim around the doors. It would have saved a lot of time in taping and painting the new trim after Excel was done, since they only install unprimed trim. Schedule: The work was completed in about 3.5 days. While this was about a day longer than originally quoted, Excel kept us informed of issues encountered during installation and their impact on the schedule. Leo, the person who scheduled the install crews, was very responsive and accommodating in finding days that worked with our schedule so someone could be home while the work was going on. Product: The Thermal windows we purchased (mostly double hung) are working great and we immediately saw an impact on our electricity bill since we no longer have the 20+ year-old drafty windows that were original to the house. The new windows are easy to move up and down and we like the additional features such as the night locks, screen locks and InvisiScreen. We went with a more contemporary window grid instead of the traditional colonial grid on the windows we replaced, and Excel helped us visualize the windows before ordering them by preparing a mock up of a couple of the windows to make sure we were comfortable with how they looked. We really like how they turned out. We had some issues with the sliding glass doors we purchased in that one of the doors was found to be bowed after installation (factory defect) and had to be replaced. The screen doors had to be adjusted a couple of times so they locked properly. More of a nuisance than anything, and Excel quickly acknowledged there was an issue and did what they could to resolve it as soon as possible. Customer Service: Throughout the process with Excel Windows, we found them to be very professional and responsive to requests and communications from us. Even after the windows and doors were installed and the check was cashed, they called to check up on things and quickly sent someone out if tweaks to anything were needed. As we entered into our first window replacement adventure, customer service and communication was the most important aspect of the project to us, outside of installing quality windows that would last for many years with minimal damage to the surrounding trim. Excel Windows met our lofty expectations in this area, and we would definitely call on them in the future for any window/door needs. We highly recommend them to anyone looking to take on a window and door replacement project, whether big or small, as they did a great job with our fairly large project."

"I found him on Angie’s list and he was the first one to reply. I explained what I needed done and I was given a good price. Two guys came on time a little early to beat the thunderstorms that were coming our way. Some of the windows couldn’t be cleaned because they were thermal insulated and you couldn’t get in between the glass. They also cleaned up our gutters and cut the hedges in front of the windows. It took longer than expected but they did a good job. They had missed a few windows but once pointed out they cleaned them."

Windows FAQs, answered by experts

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Impact windows are a type of window made with impact-resistant glass, designed specifically for hurricanes. The glass, treated with ethylene-vinyl, can withstand winds up to 200 mph, as well as flying debris. Brands sometimes test their impact windows with large missile impact tests.

Impact windows may be required in some places. For instance, the Florida Building Code requires homes to have impact-resistant windows if they live within a mile of the coast where wind speeds can reach 110 mph or more.

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Wood windows will help keep an old home's charm, but they are more expensive and harder to maintain. Vinyl or fiberglass windows offer the best benefits in terms of durability and ease of care while still somewhat blending into the look and feel of an older home.  If the vinyl or fiberglass looks too out of place, consider adding shutters or something similar. The cost of plantation shutters is about $2,990, but the charm they bring to a home is unmatched.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.
