"All Under One Roof did an amazing job with my roof replacement. My roof was leaking for the last couple months so I decided before winter to replace. When they were replacing it I was informed and shown pictures of how bad the damage was. The roof has extensive rot in many areas. All Under went above and beyond and cut out all the old rot and replaced. They went into great detail to show me the rot and how it was leaking for years, but not into the interior of the house. I am so happy at how it came out and will recommend All Under One Roof to all my friends."

"Quality firm that does great work. They put a new roof on 12+ years ago and recently came out to give us a "tune-up". Cement roof tiles. Looks like new. No issues and very responsive. Good folks."

"Tar Star Roofing (Anthony) responded in one day, inspected my roof and provided a quote the next day. The crew started work a couple days later, very professional, experienced and courteous. They completed the job on time and to my complete satisfaction. Communications from Anthony were constant, including recommendations on additional repairs as damage was found, photo documentation and expert advice. I highly recommend Tar Star Roofing for any roofing needs."

"This company provided peace of mind, value, and fine workmanship from the beginning. Scheduling was easy. The project was finished quickly, and they cooperated well with a crew that was rebuilding our chimney at the same time. Several people checked in with me throughout the process and kept me informed of the progress of the project, and almost all of it happened on schedule. The new roof looks great and we have received several compliments. I was especially pleased that this company recycles old shingles."

"We're so happy that we chose Benchmark Home Improvements for our kitchen renovation. Lee did a great job with the design. He was very responsive and had great ideas. Ian and Lee did a great job with demo of our old kitchen and installation of our beautiful new cabinets. They kept everything clean and organized and were very respectful of our house and family, even considering social distancing, etc. during this crazy time. When the job was done we had a problem installing our refrigerator they were quick to return and creatively resolve the issue. We highly recommend Ian and Lee at Benchmark Home Improvements to anyone looking for a great kitchen renovation."

"I highly recommend Pro Warrior Construction. Yann and his crew did a fabulous job installing the gorgeous Hardie board siding and the ceiling strapping on the back porch. Our house looks completely brand new! The workers show up on time and work hard. I couldn’t be happier with the workmanship. Pro Warrior is the way to go!"
