"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."

"All went well. The gentleman who was doing the cleaning arrived on time, reviewed everything that was to be done and updated the quote to reflect the total number of windows involved. I also asked that he clean the window sills. He started the cleaning and completed the work in less than 3 hours. All nicely done."

"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."

"Very prompt, clean, excellent quality work. Would not hesitate to use them again, in fact, we already did! We requested tinting for additional windows, and love the result. Highly recommended."

"Very well. The technical was prompt and he installed the film precisely. The entire process took about 90 minutes and we are experiencing less heat inside as a result of the film. One unexpected benefit is that the view from the inside of my is actually clearer and cleaner than before the film was installed. I am already planning to have more windows done."
