"When we hired Brian and his team to remodel our house, we were so pleasantly surprised at the quality of workmanship, professional attitude, and level of work ethic. They showed up everyday, on time, & didn't quit until the job was done. He painted the interior of our home, fixed & painted all of our doors, ripped out old flooring & installed new flooring, installed new baseboards along with other smaller projects. They are able to handle everything. It is so great walking into our home now. There isn't any project they can't handle. Prior to this remodel, they power-washed the outside of our home, fixed some damage to our siding, and fixed a leak in our roof. They also replaced some drywall in our foyer that was damaged by a leak. Brian's entire team worked so hard and offered very valuable advice when I wasn't sure what direction to go. I'm already working on another list of projects for them. I can't recommend them enough.Their prices are extremely reasonable. They can do it all, I promise!"
