"I wanted reflective foil installed under the joist in my attic to help cut attic Heat. The Cronkhite sales rep suggested their own insulated foil product, which I deemed Superior to what I had planned. They installed their material, we're careful about the blown in attic insulation and stepping on the existing ceiling joists. they did a good job, in a timely manner, for a job that was difficult, hot and not very pleasant."

"Everything was fine until I got the final bill. The estimate they gave was different and the final bill was different. They had put extra charges. When I called them about it, they didn't back down. They also said that because of the extra insulation they used they did they couldn't reduce the cost. Other than that, the job was done fine. At one point, the insulation had blown in, they had a little problem, but that was worked out."

"Neil did the job fantastically and explained what he was doing throughout, always asked for an inspection to make sure it was done to my satisfaction. Pricing was extremely fair and he was timely and quick. Would highly recommend for any insulation work you need done. Can’t speak on the other work he does, but if it’s on par with what he did for me, then you’d be doing well."

"Bob did an excellent job fixing my damaged vinyl sidings at reasonable price. He was responsive to my request and flexible with the scheduling. He searched and visited 4 stores to find the vinyls to ensure the matching shade. I am very happy for his work.
