A selection of 94 homeowner reviews:
“It was very positive. Jancon Exteriors did a roof for me and fixed a roof leak. I was very satisfied. He roofed the garage, and I'm actually thinking of having them do another roof for me. Everything was perfect. Usually, contractors leave messes around, but he cleaned it all up. I'd give them an A+ rating.”
“It was beyond positive for the things they did for me. They installed a new roof and four new skylights. They're very professional—I couldn't even believe it. I'd give them an A+ for sure. I have recommended them several times.”
“It was an excellent experience. They were thorough with their information. Everybody on their team was really nice. They were really helpful, they were always on time, and they cleaned up well. They did roofing. I would say they're an A.”
“The quality of their work was excellent. They get an A.”
“They did a very thorough job. They came and did it when they said they were supposed to. They finished when they were supposed to, and they did an excellent job. They built a porch. The porch was there and they pretty much took it down and replaced it. I would give them an excellent grade—the best, so an A. I am very likely to recommend them. In fact, I was thinking of calling them today.”
“It was very positive. They're local, prompt, and do good work. They just did roofing work for me. I would say A. The only reason it's not higher is the cleanliness. There were a couple of things that were still in the yard. It wasn't a huge issue, but that's the difference between the A and the A+. I would recommend them. I'm going to use them again. I'll use them again for any other work I have like remodeling outside and stuff.”
“They were fantastic. The owner, Jeff, is very easy to talk to. He's very thorough. He explains everything. He kept to the deadlines he had promised. Their office staff, Amanda, was really helpful. She was easy to communicate with by email. Everything was great. They replaced all of our windows. That was it. I'd give them an A+.”
“They did primarily roof work, but maybe a little stucco work. Shoring up some things that needed to get shored up and as a part of the process they had to do a little painting, too. I'd probably give them an A-. They weren't perfect, but they were pretty good and they're definitely an organization we would use again if we needed to. The customer service was very good. I will say that. I don't remember there being any problems. My husband interacted with them a little bit more than I did. I would definitely recommend them.”
“It was mostly positive. I think the best thing about them is that they were always on time and we never had to worry about 'Are they going to show up? Are they not going to show up? Where are they?'—that kind of thing, so very prompt, very punctual. Good at communicating when they're going to come and go. I thought that was one of the best things about them. They did a lot of work for us: roofing, siding, painting. I'd give them an A-. It's hard to judge the expertise. If somebody were to call me and say, 'Hey. I'm thinking about doing Project B,' I would 100 percent say, 'You should definitely check these guys out.' I'd recommend them.”
“I had it done a couple of years ago. I liked everything. The outcome was good. I'm satisfied with the work. Everything was good. They were clean. They cleaned up every day after they were done. Stuff like that was good. There were no complaints in the service, and I would highly recommend them.”
