"Did not recieve the estimate after the consultant arrived. When I called back received the estimate very quickly. However the estimate was over 20K for 15 plantation shutter windows which is about double any of the other estimates."

"showed up promptly saw the job, had no problem fixing the problem and was very reasonable."

"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."

"Berty did a fantastic job!  Very knowledgeable, he advised us as to the best options for our project in our budget  and we are glad we listened to him.   Very professional!  He arrived on time, completed the project on time as promised.  Was understanding when we needed to change the date and was able to work around our schedule. Very neat, the kitchen was left clean, did a good job sealing off the room so other rooms would not be affected  by dust. Pleasant to work with and a reasonable price for the quality of work. We will never go to another plasterer for our future renovation needs. The walls and ceiling look amazing!   We had another contractor come in to look at another project and the first thing he said when he saw Berty's work was "Well you got someone who knew what they were doing!"  My husband said he wishes he were around to see how he did it, the walls and ceiling were so uneven to start and when he was done everything was so even. They look beautiful now!  He did an awesome job! Highly recommend!  If you want a job well done, call Berty now!
