"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."

"Prasann was the window expert I dealt with and he was very nice in explaining the whole home genius process and giving me a good price on my windows. We went with the fusion model for the windows and he showed up to the estimate with a mask very cover friendly."

Windows questions, answered by experts

Soundproof windows can’t completely block all noises, but they will significantly reduce sound from the road, sky, or your neighborhood’s weekend activities. Choose a soundproof window with an STC rating of at least 45 to block bass tones or loud conversations. Laminated glass windows can reduce noise by 75%. You can also add noise-reducing curtains to further muffle loud noises.

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Window capping costs between $1 and $2 per linear foot. Since your average window size is 24 by 36 inches, you’re looking at 10 linear feet in total, or $10 to $20 per window. Labor adds another $30 to $100 per hour to the project. If you have custom windows, you’ll spend more to have your windows capped. Fiberglass tends to cost more than vinyl and aluminum, while vinyl costs the least but has the shortest lifespan and may have a higher long term cost.

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.
