"I Love the windows. The installation crew were sloppy. They left debris from the old windows (nails)all over my deck and Patio. The new windows created their own mess leaving behind sharp metal shavings from the casing used to wrap the windows. The caulking looked like a toddler did it with a dry finger. On my foyer window the suction cup marks are still on it. On another window the casing was installed to make the window appear crooked. If they just examined their work after they finished they would have observed their poor craftsmanship and corrected it on the spot. We are very unimpressed by the install team. Also they took out a chunk of my hardwood floor by my front door."

"It went very well. Our window shattered late the night before. We called the company first thing in the morning and left a voicemail. Someone called back about an hour later and took a description of the issue. We texted him a photo and he gave us a price right away. He showed about about 2 hours later. He came is with a mask (Coronavirus protection) and we straight to the window. He popped it out, took it into the back of the truck parked outside, where they did the replacement right on site. It took about 1 hour and it popped back on the frame very easily."

"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 FAQs, answered by experts

The cost of window replacement is about $290 per window on average, with a typical price range of $180 to $410. However, costs can be as low as $100 or as high as $780 or more. The total price depends on several factors, including the size, type, brand, and number of windows being replaced. The frame material and glass type also significantly impact the cost.

  • Frame Material Costs (per window):

  • Aluminum: $275

  • Vinyl: $550

  • Wood: $800

  • Composite: $900

  • Fiberglass: $1,250

  • Glass Type: Simple double-glazed windows are cheaper ($3 to $6 per sq. ft.) than stronger tempered glass ($12 to $14 per sq. ft.).

It’s time to replace your windows if most or many are in poor shape. In that case, new fiberglass windows will increase the energy efficiency of your home and add to its overall visual appeal, inside and out. Replacing your windows also can allow you to find a style that better suits the character of your home.

Constant fixes can be expensive over time, and by replacing your windows, you can be at ease knowing you now have windows that function properly and make your home more energy-efficient.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.

Windows may need to be replaced after a hurricane if they’re severely damaged. For example, if you have windows with blown-out glass and a cracked frame, they will need to be replaced. It’s a similar story if you have windows with noticeable water damage. However, if your window pane has small cracks but the frame is still in good condition, you may be able to repair the window.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice.
