"We could not be happier with the job that Andy and Jesse did with the window replacements. The quality of the product and the professional manner of installation was suburb, the project was done in very timely fashion, there was minimal disruption, and the clean-up was complete. We are very happy we selected Comfort Windows, and we would certainly recommend then to others"

"Had a great experience from beginning to end. C. Michael Exteriors, Inc. did a quick and easy job replacing our old picture window with this new window. Pricing and financing was much better than 2 other companies we had come out to try and sell us their windows. Thanks C. Michael Exteriors"

"Everything about our relationship with Graves Bros. during the window project has been excellent: from the initial estimate, details about start times, the crew that installed the windows, and the office personnel with whom I spoke about billing questions. The crew of Bob, Joshua and Kyle were in our house for two days and were professional, efficient, friendly, courteous and really knew what they were doing. There were a couple of unexpected problems which they didn't ignore but rather came up with excellent solutions. We are 100% pleased with Graves Bros. Home Improvement and recommend them without hesitation. We called them for the window project because they had been equally professional when replacing our roof 2 years ago."

"I purchased an exterior door and planned on installing myself. Realizing that was not as easy as I thought, I looked for a professional. I found Brett and my worries went away. The process was easy and I couldn't be happier. The work was professional and thorough. He did everything start to finish. I am so impressed with his skill set. His knowledge and skills will make any project you have stress free!"

Windows FAQs, answered by experts

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

Installing bifold windows can take anywhere from three or four hours to several days. Smaller bifold windows that open vertically and fit inside your existing wall opening should take just a few hours and no longer than a day. Larger bifold windows, especially wider ones, may require structural work before your professional can install the window. The installation could take two to three days, depending on how much work your wall needs.

Bay windows are expensive mostly because their above-average size means higher material costs. Unlike bow windows, most bay windows also include casement windows on either side of a picture window, and the opening mechanisms for casement windows drive up costs. You’ll also pay higher labor costs to install a bay window, as you’ll often need multiple technicians to lift the window into place.

A window may fail because of age, defective mechanisms, or moisture. Depending on the issue, the window may be fixed with simple repairs. Otherwise, you’ll have to invest in replacing it. You can avoid damaged windows but keeping up with window maintenance.
