Recommended Customer Reviews

My husband called them and they did arrive within hours. But, they came and looked at our water heater issue, took $39 for show up fee and we never heard from them again. They said they would give us a quote. Nothing! They even asked to use our bathroom during a pandemic.
Stay away!

I called Guarantee late on a Friday to help diagnose a low water pressure issue. They had someone out first thing Monday morning.
When they knocked on the door, the technicians were wearing masks and made sure it was ok for them to enter. While one checked the pressure outside, another allowed me to show them what was happening inside.
The technician told me the pressure was low and there were a few things it could be. He walked me over to the water line boxes near the curb and showed me the water pressure regulator valve. He explained that it could be that it just needed to be adjusted. He talked me through everything he was doing while he did it. Meanwhile, as he made adjustments, the other tech was taking reading at the hose bib.
After he righted the pressure to 70 PSI, he said he wouldn't charge me the full amount and only charged $45!
They were gone and my problem was fixed in 20 minutes! I felt like they were very transparent about what needed to be done.

I was quoted in $89 fee as an hourly rate over the phone but when the plumber left after 20 minutes of labor he charged me $297. $45 was for Parts and $252 was for labor for 20 minutes of work which is highway robbery do not call guarantee plumbing

Best service in the area! I've been using their services for the past three years. All my experiences within the company have been fantastic. They are very honest, provide prompt service, and are genuine people. Highly recommend to anyone in need of their services!

By far the best service I have ever received! AC went out on a long holiday weekend. A tech was dispatched and was able to get the unit running even though it was in need of replacement. Replacement quote was very competitive and complete and upgraded system was ordered and installed without haste. Techs were very courteous, professional and clean. Follow up calls made by Guarantee Plumbing & AC to check on the service received and to ensure our satisfaction. Service was so great that I signed up for their Plumbing and HVAC maintenance plan!!
You are making a mistake if you do not call them for all of your needs. Highly recommend all of their services.

I called Guarantee Plumbing after coming home from vacation to find my house flooded from a broken pipe in my bathroom. Guarantee plumbing sent their plumbers to my house the same day. I believe one of plumbers name was Manuel. Manuel was very professional and explained in detail to what needed done. The two plumbers who came to my house stopped the water and fixed the piping quickly and also helped me clean up the water. Guarantee plumbing went out of their way to resolve my problem.
I will definitely recommend Guarantee plumbing to any oh my friends and relatives.

This is the most courteous company I've used precise professional and very reasonable prices!Most definitely and highly recommended. Won't use any one else.

I made an appointment with them and they didn't show. I called and they seemed to forget my appointment but insisted I was on the list. They offered to reschedule, without apology. I went with another plumber and saved some money.

This is the second time I have had to use Guarantee for service and both times we have received excellent service by the technician Bill. This time he had an assistant with him. We had a clogged drain and he listened carefully to my description of the problem and you could see him thinking as I was talking. Because we live in a mobile home, Bill has a unique perspective because he has lived in one, too, so he is familiar with the issues of mobile homes. He then went out to our clean out plug and started his investigation and easily saw that the problem was downstream of that point and it was the park's problem. He then went over to the park office, explained everything to them and got a commitment from them to fix the problem. Then he came back in to my wife and I, explained everything to use, told us we were only liable for the service diagnosis charge of $39.95. We gladly paid him, chit-chat for a minute or two and said we'd see him in two more years. Don't hesitate to use this company.

Best plumbing service ever!!!! Troy King was at my house in less than an hour after I called. Replaced my water softener and worked with me on the price. Did a number of small plumbing jobs as well. I will always use this company for all my plumbing needs! The company also gives a 10% military discount. Troy was very professional and knowledgable and went the extra mile to complete the job.
