★ 5★ 4★ 3★ 2★ 1Excellent service! Thought I needed a water heater but my Merlo serviceman, Tyler, said I didn’t need it. They did not sell me something I didn’t need! He also did some other plumbing for me that was not previously scheduled. This is a top notch company! Check them out and ask for Tyler! 5 stars 👏
May 30 · Maureen WirthInstalled water heater and updated much of the galvanized steel pipe work (100 year old property) in a timely fashion. Worked with both Matt and Doug, easy to communicate with both. Integrity in their work; could have updated more, but they advised not to spend too much money until a direct need arises. Reasonable pricing and will be using them in the future for plumbing needs!Doug Back out Feb. 2022. Was on time , only took about 6 hours what we expected to be 8 in changing shower components, pipes, and a toilet. Old toilet didn't have a shut off valve, so provided a long term valve replacement that avoids having to dig into walls to replace galvanized steel pipes (again old house problems) that would cost us more money & hassles!
February 27 · Dustin PriceSo glad I got my water heater replaced with Merlo. Doug did a fantastic job. I highly recommend Merlo if you want high-quality work at a fair price.
February 10 · Caroline BaileyWorst people to ever do buisness. They delayed my permits by three weeks. The best was they said they would dispose of my credit card numbers yet didn’t for over three weeks without my permission. They called my landlord as well saying wasn’t going to pay a bill that was not even past DUE! Be careful
January 21 · taylor bI couldn’t be more happy with Merlo Plumbing. They were able to find my problem and fix it, for now. It’s only because my house is old but for now I have a problem fixed. The young man was knowledgeable and cleaned up afterwards. I would recommend them to anyone.
November 20 · Joann BatesMy husband has Alzheimer’s and flushed hand towels in two of our bathrooms. We took a chance and called this service.Our tech was veryprofessional and understanding. He fixed everything and his charge was very reasonable. Merlo is definitely our go-to plumber now. Highly recommend.
