"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."

"Out of several companies I called to install a window well, Manny was the only one who understood what I wanted and gave me an upfront cost. I had 2 other window well drains previously installed by the prior owner of my home. Other companies wanted to talk me into things I did not need or want. They were prompt, completed the work with minimal issue and left the area relatively clean."

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
