"Beyond impressed! Rob came out, made recommendations on a window film product that will give me privacy yet still let the natural light shine through. Install was flawless, recommendation couldnt have been better, Rob and his crew really took care of my business. They were polite, informative and they cleaned like they were never there. Thanks Rob and crew!"

"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."

"Professional, experienced and efficient. Arrived at 10:30, finished installing 12 windows at 6:30. Even had someone come and take away my old metal awnings. My only reason for a 4 instead of a 5 is because of the dust and dirt the installation caused. I never should have cleaned BEFORE the installation. Green Star vacuumed and cleaned up the big debris but it took 3-4 days to clean up the fine dust and dirt."

"Sunbeam replaced all my hardware with materials that have weathered through all these crazy winds. I was very happy with my Awnings’s so I ended up having them replace my front door. Only negative thing I can say is I found them to late. Would have liked to have them replace my windows as well. Service after the sale. They are the best"

"I had a fantastic experience with Energy Windows from start to finish. From purchasing the window to installation, everything went smoothly. Ian made the entire process super easy and was very informative about the windows, answering all of my questions along the way. The installation was completed in a timely matter, and they did a fabulous job. I couldn’t be happier with the outcome and would highly recommend them to anyone looking for quality windows and excellent service!"

"Angel installed a new vinyl floor, cabinet, and sink in my laundry room. Also replaced an interior door, and did troubleshooting on a leak we were having in our sunroom. Angel stayed in touch throughout the process, arrived on time and did flawless work, we couldn’t be more pleased. Would highly recommend for any home improvement projects you may have."
