What Our Happy Customers Say

We take pride in what we do. That’s why we ask our customers for authentic feedback about their experiences with us. Here’s what they have to say:


I called Larry early on a Monday morning for a basement that was taking on water. He came out right away and was very knowledgeable and replaced my ejector pump and dealt directly with the home warranty company.

I was surprised by how smooth the whole process went. I felt like Larry really cared and he had some great suggestions about what to do in the future. Top notch service!

Awesome job as usual! William installed a new toilet for us and fixed our kitchen sink faucet. He was on time and was very informative. He always does a great job! Thank you

We called Instant Plumbing at 1:00 p.m., they said they could send Angel out in about 30 minutes. I got 2 texts, the first one confirming arrival at 1:30 and the second one stating he was en route.

Angel arrived at 1:30 and it took him 30 minutes to fix the toilet that wouldn’t flush. Angel was friendly and provided speedy and accurate service. Would highly recommend Instant Plumbing.
