"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."

His knowledge and skills will make any project you have stress free!"

Windows FAQs, answered by experts

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

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.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

Yes, selecting double glazing or low-E coatings to reduce energy costs.
