"Our dog broke glass in our front window on a cold, Saturday afternooon in January. I called Glass by Ro and they were at my house in under and hour. Not only did they fix the glass, they took, care of the storm window, which had come off. Their work was immaculate and done with efficiency and care. Highly recommend! I would use them again for any window or glass needs. Fabulous work."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

Windows questions, answered by experts

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

While plywood will keep winds and debris from shattering your windows from the outside, window film can help protect your windows from the inside. Window film can keep a window from shattering. If your windows break, the film can hold the shards of glass in place, reducing the risk of cuts.

While you may sometimes see window film marketed as "hurricane window film," note that it doesn't provide sufficient hurricane protection on its own. It's no substitute for plywood, storm windows, or hurricane shutters.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

Bay windows and garden windows differ in both size and window angle. Garden windows are smaller than bay windows and extend from the house at 90-degree angles, creating a box-like shape. Bay windows, often much larger than garden windows, consist of three windows set at 25- to 45-degree angles to jut out from your home.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.
