"Gary and his crew did a excellent job replacing 5 windows.. I had a few other companies give me quotes and Gary's was the best by far. His crew replaced the windows with speed and cleaned and removed all the debris within a few hours. So far the windows meet all my expectations and really make a difference in the comfort of the rooms ."

"Had a problem with a pet tearing my screens. Jay gave me his expert opinion and recommended a pet proof screen. He installed that in the back and a regular screen for my front door. They both look great. So far so good with the pet screen! ?"

Windows questions, answered by experts

Shatter-resistant glass will ensure that even with a high impact, the glass of your window panes is less likely to break. If you’re looking for a more low-cost way to prevent vandalism, the most traditional answer would be to board up windows with a strong plywood sheet. Adding security cameras is also a surefire way to ward off potential vandalism. 

Consider energy performance ratings, durability, aesthetics, and ease of maintenance when selecting windows for different environments.

Folding window installation costs about $1,600 on average, ranging from $500 to $3,000. The cost factors of this project include the size, the type of folding windows, the number of panels, and the type of glass. Different types of folding windows include:

  • Standard folding window: $200 per linear foot

  • Glazed folding window: $240 per linear foot

  • Standard folding window and swing door: $1,000 per linear foot

  • Folding window and sliding door: $2,000 per linear foot

You should board up windows when you need to protect your home either from intruders after a window breaks or from severe weather before you experience damage. To maintain home security with a broken window, get your window boarded immediately. If there’s a hurricane, tropical storm, or tornado expected in your area, board your windows a day or two beforehand to avoid emergency service fees.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.
