We’ve had Guaranteed Plumbing out for several different things. We love working with them and they have great plumbers on staff. We’ve had Drew out each time and he is our favorite plumber. He is a hard worker and does high quality work! We love Drew and Guaranteed Plumbing. They will be our go to plumbers for life.

Drew solved and fixed stubborn problems with a leaking toilet and low water pressure in a kitchen faucet. Great job.

I've been using Guaranteed Plumbing for 15 years now. They have worked on my home as well as my rentals. They are always on time and are very professional and kind. Every repair they have ever done...I've never needed to call them back. When they do a repair...it is fixed. I've been very happy with them and will continue to use them for any plumbing issue. They do quality work and don't cut corners.

We have used Guaranteed Plumbing for 7 years, and they have handled every emergency, maintenance and remodeling work for us with exceptional professionalism, courtesy, reliability and expertise. Marcus, Paul and Derik are a rarity in today's world. We highly recommend their services.

Anne Wegher on Guaranteed Plumbing

My husband and I were extremely satisfied with the professionalism, punctuality and the quality of materials used by Guaranteed Plumbing. Paul worked with us over the phone to provide an estimate late one afternoon. (We were in a "pinch" when our water heater went out and we were expecting houseguests for a week beginning the next day.) Miro arrived the next morning exactly as promised and completed the job very capably. He explained the functionality of our new water heater to our complete satisfaction. If we have another future plumbing need, Guaranteed Plumbing will be the first on our call list.
