What customers said about shower repair
Jetter Clean Advanced Drain Clean…Had a different company come through to take care of the clogged tub drain and it was a total fail. Jetter Clean Mankato then came through and took care of the problem fast and easy! The technician, Cody P was on time, very professional, polite and right to the point. Great service and price! I highly recommend Jetter Clean Mankato for your drain issues!
Babe Plumbing Heating and AirAfter our experience with Bo and Babe Plumbing, there is no one else we’d use! From the beginning they were attentive and extremely communicative. With multiple sick people at home, Bo worked around us all and even let my 5 year old bring his flashlight in to look at what he was fixing. Every step of the process was…
Plumb-Rite Plumbing, LLCEach time I have called them they were scheduled within a couple of days. They are professional yet understanding and compassionate. Having bought a 80+ year old house we have had many surprises and they have been able to help with all of them so far. I recommend them to everyone I know who is looking for a dependable plumbing service.
Jetter Clean Advanced Drain Clean…Mitch did a great job explaining the issues and options for repairs. He was on time, friendly and quick.
Jetter Clean Advanced Drain Clean…Matt came out and unclogged the drain in my apartments tub, he was highly professional and even took the time to clean the tub up after he was done. I am very happy not to be standing in 4 inches of water while I shower now.
Babe Plumbing Heating and AirPrompt and courteous. Their pricing was was better than expected. I'm definitely going to call them in the future. Bo was the tech that came to our rescue. The work he did was the best
