Hear from Our Happy Clients

We had a great experience from start to finish. We hired Kaz to replace our siding gutters, and install a gable roof to our front porch. As the crews were working every day the lead construction coordinator Phil was always showed up make sure everything was done properly.They were always responsive to our needs.Even after they were done. We had a couple of small pieces of siding that we wanted changed and they always responded and came back to resolve the issue so it seemed like once the company was finished. They were still here to back up their work, which is important . We chose Kaz due to the reviews and I’m glad we did. They did a wonderful job.

I called Kaz about missing shingles on my roof from the wind and they said Chris B. would call. He did following week, scheduled to come to house and discuss what was to be done along with a downspout gutter replaced. Was a fair price. He came a week or so later. He was great to talk to and great to work with, kept me abreast of work done, maybe halfway thru job. Also showed me at end what he did. Girls I talked to on phone were pleasant also. I am having a window done also by them. Would recommend them for any work.

Had a new roof installed and siding replaced - very happy with both projects. Teams were very professional and work done timely - workers cleaned up thoroughly at the end of each day!
