“Diamond Plumbing has always responded promptly and has done an excellent job for us. Mike has installed new bathroom fixtures, safety handrails in our guest bathroom before our elderly parents visited. He also came to the rescue fast when we had a clogged kitchen drain. When I have a plumbing need, Diamond Plumbing is who I call.”

"Mike Dornisch of Diamond Plumbing has solved many plumbing problems in my home. Everything from fixing a leak in the water line for my refrigerator to helping me choose a quality filter for that water line and then installing it to replacing unsightly, outdated faucet handles to advising me on a new garbage disposal and installing it. Mike is courteous, friendly, dependable, experienced, cost-conscious and a pleasure to work with."
