"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Received very informative presentation on what to ask and look for when window shopping. The only reason I didn't go with WoW was due to another company being slightly less expensive."

"I received quotes ranging from 5k to 800.00. This company was the only one who told me that my windows might be under warranty, and they tried to save me money. With honesty like that, you can tell they hire staff with integrity. I would gladly recommend them and work with them again for any future window repair needs."

"Eddie was highly knowledgeable and helpful after my kids broke my window during a winter storm. He replaced the glass in a challenging situation. I highly recommend him."

"this company replaced a broken window pane for $250. the work was done very fast and on time for a fair price, and the final product is good. only complaint is that i found small shards of grass on the floor of the room where they were working for about a week afterwards."

"The Glass Smith installed windows in my upstairs master bathroom and main level laundry room. They provided excellent, professional, and honest service. Devin, Head Manager, was engaging, friendly, and efficient. He provided exceptional customer relationship management. Jermaine Science, Master Technician, is truly a master in his craft. He was thorough and yet efficient. He also caulked several windows and corrected flaws of a previous window installation company. Without any reservations, I recommend Jermaine for any window project."

"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."

"Came when they said they would. Brought all the materials and replaced our window frame and all in 3 hours. Not only knowledgeable but very courteous and friendly. Our window looks wonderful and I would certainly use them again!"

"Fantastic experience with JS Jackson! They did 2 projects for us - window replacement (6 windows for a townhouse) and cut and install new kitchen window. The leads on each project were very knowledgeable and great at explaining the process, answering questions, and advising on the best products for quality, budget, design, and function. Workers were friendly and professional. The office staff is very responsive at handling scheduling, permits, invoices, etc. It’s been several months and the windows are clearly properly installed, well-sealed, no leakage, and outside framing looks flawless. Would hire again!"

"Highly recommend this company for window repair. Highly professional, friendly and helpful. Pointed out issues we had missed and fixed all issues quickly with high quality work. Repaired/replaced windows which had blown seal/discolored, repaired window to smoothly open, fixed window screens. Could not recommend them more."
