Recommended Customer Reviews

Dominique and Ron were great. Came out on a Sunday call within an hour and completed the job in less than an hour. Very friendly and helpful.

Ron and D were great! sunday morning emergency plumbing issue and they were here! Job was done perfectly and clean up was complete!

A1 plumbing is punctual efficient, thorough and the plumber Ronald and his assistant Dominique were very polite. I'd hire them again to do any job for me in the future.

We have worked with A1 Plumbing multiple times (we have a very large tree in front of our house and the roots create a constant problem) and have never been disappointed. Our most frequent plumbing issue was a shower pipe that disconnected from the main line and was leaking water under our house without us knowing for weeks. I called Vince on a Saturday morning and Ron and D came out and spent the majority of the day fixing the issue and cleaning up the water under the house. They did a wonderful job and we have peace of mind knowing that there won't be additional problems in the future. Plumbing issues are never fun, but A1 Plumbing is beyond helpful and will get the job done correctly and for a fair price.

Great, fast and efficient service. Ronald and German installed my water heater and left the area cleaner and better than before. These gentlemen are knowledgeable professionals and they did excellent work. Zero complaints from me.

I'm very satisfied with A1 Best Plumbing services. This is the first time I use them. I called them late last evening and they took my call. Their prompt response and effectiveness in installing a new water heater this morning is greatly appreciated. German, the technician, was very courteous, prompt and efficient. Thanks you!

Had a really nasty experience with grey water gurgling up into my kitchen sink this past weekend. couldn't get a hold of the HOA on time so called a company that told me 2 hr waiting time. by then the HOA called back and said they have A1 Best Plumbing on the line and they can be there within the hr. of course i took the lesser time and talked with Vincent for a second and he assured me he had his team member Leo on the job. Leo arrived under an hour and handle everything in a timely matter and was very polite. hope it never happens again but I would call A1 again if needed.

Very professional. Timely, courteous, reasonable, and expert workmanship. When Mike Diamond fumbled, A1 picked up the job and scored big time!!! Grateful for Vince as a problem solver, and especially Ron and Dominique for their work ethic, professionalism, and quality of work. Honest problem solvers.
I will call A1 again without hesitation. Real Pros.

This is the first time I called them in the late evening & they were able to fix my kitchen sink clogged-up issues on the same night.
#1 Reliability! Awesome!

Service call $179.00
Rancr toilet $200.00
Water extraction $250.00
Mainline $250.00
Total $879.00
Plus 3% credit card convenience fee $26.37
So the total should have been $905.37 BUT the invoice was for $909.76?!
You may say it's only a very small difference, but my main beef was they did not call me to let me know how much it was going to cost instead of obtaining approval from the tenant. Yes it did have to be cleared but I think they should let the owner know first exactly how much it was going to cost plus the 3% credit card convenience fee that will be charged on top of it. I would have appreciated a full disclosure, and an accurate billing total.
