I am more than impressed with my new windows! Nova came and did a custom job at Cambridge Courts for my condominium. The quality and care is amazing! They even came back to replace a screen that was not in the original packaging. Thank you so much!

From start to finish, NOVA Installations exceeded our expectations. We replaced two exterior hinged doors with Provia doors. The price point was higher than doors you see at HD or Lowe's, but competitive with other (Provia) door installers in the area. The quality was exceptional. The sales person did an excellent job of presenting the benefits of Provia Doors. The person who came to measure was knowledgeable and even offered some suggestions on the installation. The install team was on time and did a professional job. Five stars!

Window replacements were completed in just two days. Professional and courteous workers, good attention to detail, minimal disruption to indoor and outdoor surroundings. NOVA also completed a roof replacement for us in one day which minimized disruption to townhome neighbors as well. Even returned a second day for additional cleanup since it was windy the day of installation.

NOVA Installations replaced our windows about 10 years ago, and since we were so happy with their work, we were fully confident in having them replace our roof. Both my friend and I had owner Art Dunn give us an estimate on doing two roofs. Even with the several price increases on construction materials over the past year, Mr. Dunn gave us a very competitive price on upgraded shingles that was better than some of my neighbors who had their roofs replaced by storm chaser outfits last year after a hail storm hit our area. Without any hesitations, we accepted NOVA proposal without having to get any other estimates. My friend and I are extremely happy with our new roofs. Mr. Dunn's crew worked hard, and meticulously did a very professional job in installing a beautiful roof. They met my specific request to have the ridge vent installations extend to the ridge edges so the roof lines would look balanced, unlike some other installers who just do the minimum length. The crew also did a fantastic job of keeping the work areas cleaned and protected all the shrubs with large tarps. The cleanup included a worker using a magnetic rake to comb all the areas for fallen nails. Mr Dunn even stop by after the job was done to do another sweep himself. That's what I call unbelievable customer service. All my friends and relatives who have had NOVA do work for them have been completely happy with their work and service.

Nova Installations installed a bay window at my house a few weeks ago. There were no exterior windows on the wall before so they had to create the opening in the exterior wall to get the bay window in. All the work was done in a day. We couldn't be happier with the results. They did an awesome job and for a really really good price. The bay window they put in looks great and we love our new view. We will definitely be going back to them if we have any future window work needed.
