"The process with Zen Windows from start to finish was exemplary. David, the sales rep, the second measurer, office staff, James the production manager and Scott the owner could not have been more pleasant. We replaced 7 really bad windows and have just a few others to replace in addition to a new front door. The installers respected our home, did an excellent job from start to finish, couldn't be happier with the whole experience with Zen Windows!"

"Excellent experience! They did an amazing job with our windows (inside and out), screens and window sills. I just keep admiring my windows and how clean they are now. Highly recommend!"

"I am very fussy and frequently critical, yet I have only the best things to say about Unicorp window replacement. The owner came to my home - on time - to explain all the options and costs for replacing my windows. It didn't feel like a sales pitch, but more like a discussion of what was best for my home. Unicorp is a local company and makes their own windows, so I knew if there was a problem, there would be someone nearby to call. My windows were installed on time and the crew was very professional. They are very hard workers; they didn't even take a lunch break. I was assured that my new windows would not let the cold air in, as my old windows did. I'll have to wait for winter to test this out, but I have confidence that since these windows were custom-made for me, they fit more tightly. It has been a pleasure to find a local company that has an excellent product, is honest, and reasonably priced."

"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+++"

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"Windows and sliding doors cleaning were great. Power wash included gutters which really needed it! Small issue of a broken flood bulb was resolved the next day and the resolution was above and beyond expectations. Will using them again on the spring!"

"Broken window is better than it was before."

"All the workers were very good and they did an excellent job replacing my windows in an organized manner. I am very happy with the way everything turned out. My windows look great."

"Very prompt and professional.  Recommended the appropriate tinting for each set of windows.  Quick, neat and finished product looks great!

"It went very well considering the weather did not cooperate. Pete's crew came promptly at the time scheduled to do the power washing and clean the gutters even though we were experiencing light rain showers. They did an excellent job. They even power washed the mailbox post even though it was not part of the work requested. Because it was raining and the deck needed to dry before applying stain, the windows and stain application were scheduled for 3 days later. Again, Pete and a crew showed up that Saturday at 8am and worked until 6pm. He also used a moisture meter to make sure deck was dry enough to stain (there had been a brief light shower the day before). We have a very large deck, so they were not able to complete everything. Pete returned the following Tuesday to finish staining, repair the lattice and water proof the wood along the walkway. There was a small section of grass that somehow had been damaged when the crew was applying the stain. Pete went home where he happened to have some sod and brought enough to repair and cover this section of the lawn. Through the entire process, he was very proactive with phone calls and emails and responsive to all questions and inquiries regarding the work. His crew was polite and worked hard. I very pleased with the results."
