"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"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."

"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"This company was thorough, professional and punctual. The gentlemen doing the work were friendly, explained everything in advance and did exactly what they said they would do - spotless windows, sills and screens, inside and out!! I would DEFINITELY recommend them for anyone's window cleaning needs!! A+++"

"How wonderful my most lovely windows are from Windows on Washington & their installation team was brilliant at keeping all my furnishings covered. They were on time, efficient & most polite. I highly recommend them."

"They were very professional and the price was more than fair for the replacement of glass in 2 windows."

"Wonderful to work with. Very honest and willing to work with you within budget. We had several windows that were chipped by the home builder. Jeremy was happy to complete the job at a later time when we could get the windows replaced. Flexible, honest, and very pleasant to work with. I wish all contractors were as outstanding as Jeremy!!!!"

"They rebuilt my broken window from the pieces, it saved me lots of money and grief, since new windows would not match the old ones."

"very reasonable--suggested me to bring the window to the shop to save on cost of sending workers to my home.  thank you!

"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!"
