"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."

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

A window can fall off a track for a large number of reasons. The most common ones usually involve an issue with the track itself or the wheels that glide along it. If the track is bent or broken, the wheels can’t slide. If the wheels are broken or are full of debris, they won’t spin, and you will have to force the window open. The good news is that most window track issues are easy fixes, even for beginner DIYers.

Yes, home appraisers look at your windows when appraising your property to determine the market value of your home. They’ll factor in the type of windows, quality, condition, whether or not there are screens covering the windows, frame materials, size, insulation, and more to come up with an unbiased property assessment.

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.

Yes. Vinyl windows have a PVC frame that wraps around a glass panel that is usually made up of two thinner glass panels separated by an insulating, noise-absorbing airspace. Some vinyl windows are triple-glazed, with three insulating air panels within them. This glass helps keep your interior quiet from outside noise while its insulating qualities help your space stay cool in the summer and warm in the winter.

Garden windows last about 15 to 30 years, depending on the materials, ongoing maintenance, and local climate. Fiberglass and wood windows tend to have the longest life spans as long as you keep up with cleaning, lubricating, and refinishing them. Make sure to inspect your windows about once a year for signs of trouble, like worn-out seals, frame damage, or cracks in the panes.
