"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."

"Fred, Cleveland and Kenny performed a miracle here. I only wish I could post the picture I have of Fred cleaning the very top of my cathedral ceiling window. I could not believe that they were going to take the mullions out and clean them as well as the windows.. Fred also figured the the ceiling fan, when turned on , would get the windows dirty, so he cleaned that too.. All done with pride of professionalism and friendliness. Thanks so much ..."

"We had three older windows replaced because they were drafty and starting to show their age. The whole process was smooth, and the crew did a great job. The new windows look great, and we’re very happy with the results. I would definitely recommend them."

Windows FAQs, answered by experts

When comparing impact windows vs. hurricane shutters, it’s important to consider the protection and installation details to determine the right choice for you. For constant protection against storms and flying debris, impact windows are a better option than hurricane shutters, especially if you don’t want to install shutters that will change the look of your house. However, impact windows are more costly than hurricane shutters. If you want a budget-friendly option that’s still protective against storms, hurricane shutters are a solid option. 

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Impact windows are a type of window made with impact-resistant glass, designed specifically for hurricanes. The glass, treated with ethylene-vinyl, can withstand winds up to 200 mph, as well as flying debris. Brands sometimes test their impact windows with large missile impact tests.

Impact windows may be required in some places. For instance, the Florida Building Code requires homes to have impact-resistant windows if they live within a mile of the coast where wind speeds can reach 110 mph or more.

The gas between window panes, typically argon or krypton, acts as a barrier to heat transfer. This means it helps keep your home warmer in the winter and cooler in the summer by preventing heat from passing through the glass. This gas layer also reduces condensation by stabilizing the temperature across the window and helps minimize noise. Essentially, it’s all about improving energy efficiency and comfort while lowering those utility bills.
