Recommended Customer Reviews

Really happy with Rapid Quality! They were awesome and helped us figure out where the leak was coming from even on a weekend. Very responsive and would use again in a heartbeat -- although I hope we don't have to!!

We had an unfortunate leak under our slab on the weekend and I placed a call to Rapid Quality Leak Detection. Josh immediately returned my call and scheduled an appointment for the next day. Although he was running late, he communicated to me his status and arrived promptly at the revised time. He was thorough in his assessment, provided pictures of the issue and spoke with our plumber to explicitly explain the situation.
We appreciated Josh's professionalism and will definitely recommend Rapid Quality Leak Detection to others.
Thank you Josh.

Set up appointment and given a time. Josh was very clear and punctual. He used his equipment to verify the location of the leak . Can't say enough good things about this company.

Rapid has been helping our Homeowners Association try to nail down the source of our irrigation leak. The service has been fantastic. The response time was quick and their rep was on the job within 24 hours. He nailed down the general location and the plumbers came close (the leak is under concrete walkways and steps). Rapid's Rep (Josh) came down again right away to double check and he pinpointed it better for the plumbers. You don't want to have to cut out too much concrete! Pricing was very reasonable too. I highly recommend Rapid.

I called the company and was able to get a specialist out within hours. Josh was spot on, detecting the leak, had a very reasonable fee and was able to advise us on repairs, saving us tons of money. Best service.

We had a maddening leak characterized by water continuously leaking into the gutter from the drain, and the meter moving even when everything in the house was off. We had our plumber, our landscape guy and our pool guy inspect and search and they could not identify the leak. Josh came out and in his initial inspection, we thought he identified the leak, as being associated with the pool fill apparatus. We turned off the pool fill and the meter stopped moving, so we thought we were done. After he left, we noticed that the effluent was still emitting from the drain pipe, albeit a little more slowly. And the meter was still moving, only very slowly. About one digit every minute or so. So Josh came back out and pressure tested the input with toilets off, sinks off, appliances off, still couldn't find the leak. Then he inspected the property for moisture and couldn't find anything. Then the last step was to bypass the water treatment system. We hadn't done that before, because the water treatment system was tight and dry. But as it turned out, the system had corroded (20 years old) and was leaking into the drainage overflow for the system. We bypassed the system and the problem was solved. He went above and beyond and didn't charge extra for the multiple visits. Has all the tools and does diligent work. Nice fellow to boot. Highly recommended.

I have a rental unit that had no hot water and was told by a plumbing company that I had a slab leak somewhere around my rental property. Of course I didn't believe it at first until I decided to call Rapid Quality Leak Detection. Josh and his worker responded on time and didn't waste any time. They were very professional and explained everything to me while he was working. They had all the equipment to find the source of the leak. The cost was reasonable and I was glad to know that I could now move forward in fixing the problem. I would hire them again with no hesitation.

Called rapid quality to check for a leak and it took no longer then 20min to find leaks... had my plumber come and fix leak within 2hours

My water bill came in the mail and noticed I have a water bill 4 times higher than my previous 2 months. I walked the house and yard, I didn't notice any water anywhere so I called a plumber, he checked all around too and he said it's possibly a ""slab leak"" and told me to call a leak detector so he didn't have to break open different areas to try and find leak. I didn't know that there was such thing as a ""leak detector."" Anyway, I looked on Yelp and found a few companies and this guy was available the next morning.
Josh came out the next morning took out some inspection camera thing and scanned the floors and found a hot area in the kitchen under refrigerator. Once he figured out the area he tracked the pipes under the bathroom floor and then started listening to that area and brought out some tape and marked the spot. I didn't understand how he came for an hour used his equipment, marked the spot where the leak is. The next day plumber came and broke the floor where he marked and there was a pinhole in that exact spot. Amazing work . Blew me away. I couldn't. Highly recommend!!

I called to make an appointment and they responded right away.They also were very thorough in what needed to be done to fix my leak problem properly!Thanks again,I'll definitely be recommending to my friends:)
