Nova Exteriors Inc
Nova Exteriors Inc
NOVA Exteriors, Inc. is a 12 time Angie's List Super Service Award Winner in several categories. We specialize in exterior remodeling and have over 50 years combined experience in the Metropolitan Area. We take pride in our work and we would appreciate the opportunity to showcase our services.
"NOVA Exteriors did a wonderful job replacing 3 exterior doors at our home. They checked every box one could ask for. Rob our sales rep was patient and understanding of our needs - even coming back a second time as we had a hard time deciding on what we wanted. Their team worked quickly and did a great job installing some beautiful new doors. We noticed after the installation that there were some imperfections on the hardware installed and they have agreed to replace them & their customer service was top notch. They responded quickly to some minor concerns and went above and beyond to fix the problem. While doors are never cheap, their price was right in line with other Provia vendors and 1/2 the price of Pella vendors. I'd highly recommend them."

"At first I rated them a 5 but they had me put in a review before the job was even completed. They used old tarp from previous jobs. There were debris all over my bedding and furniture from the old plastic tarp. If they needed new tarp I would supply them. Who knows what the previous projects had in their homes. I didn't notice till after they left. Yes, you definitely will need to vacuum. Which I expected, but not having to wash all bedding and vacuum furniture. The windows look good, but it's so much cleaning afterwards. So when they say you'll never notice they were there. Was not true at all. One of my bushes in the front were also damaged and trampled on."

"I am still waiting for the return of my deposit as it has been a week since I put this review on hold after putting in the notice that day 24 June of cancellation by email and next day mail. As I have said before I am a disabled Vet, Senior citizen with health problems. I have copies of the emails that I sent on the days of 06/24/2023 and by next day Mail on the 27th notarized copies of the cancellation. Tried calling but went to voice mail. No work has been done so a rating cannot be done on the work, only the price. This job was way overpriced and never got the chance to compare. The salesman was a good person but I have my family doing it for thousands less."
