Recommended Customer Reviews

Excellent service. Mark was great and found the leak quickly. Great guy. Call them. I so appreciated the good communication and quick service.

I can't speak highly enough about Dominic's work ethic and dedication to quality service. We had a difficult leak to locate and he worked tirelessly until he discovered the issue. He was friendly, professional, and efficient. I highly recommend him if you need leak detection services.

My next door neighbor had a leak that came up through her floor and did some damage. When Mark came out he not only dealt with her problem but offered to help me solve our mysterious water loss problem, for free. He was very helpful, informative, and kind. Good guy. Thanks Mark, most appreciated!

Mark came out to find a major leak, 8 gallons per hour. Said the leak was at two valves. $400. Referred to someone to fix the leaf. Alex replaced the valves. $449. Did not check the meter to see if leak stopped. It Had not. Eventually I found a wet spot and traced it to a very broken main line. Finally fixed by my gardener.

We were notified of a possible water leak and were able to determine it was in our main water line that is about a 100 feet long and lies below the driveway. Mark quoted me a minimum price over the phone, came out and located the leak. The cost was what he quoted me. We dug where he indicated the leak was and he was spot on!
I would highly recommend this company!!

Bought a new house and was concerned we had a leak. We got a next day appt and Dominic came out on time and was very efficient he identified 5 possible issues luckily none of which was a huge emergency leak. He was very knowledgeable and had lots of recommendations for the next steps for us. Glad to know it's a local family ran company as well. Thank you Dominic!

I had the water company inform me of a potential leak causing 3x the normal water utilization. Leak detection pros had surprisingly NO ability to detect potential leak. Cursory walk around house perimeter and did not even check street meter to confirm leak is present with and without water running in the house. Made some non relevant comments and then left!!!. Craziest experience I have had. Avoid. Zero stars and a waste of my time waiting for them to show up.

In a word, Lifesaver! When all else fails, Dominic from Leak Detection Pros is undeniably who you want. I had a pool leak that others before him could not pinpoint, he did, which saved me from cutting up the cement in different areas around the pool to try to locate where the pipe leak was. Dominic explained the situation & options, I truly felt he had my best interest in mind. What could of become a very expensive fix became reasonable. In Leak Detection Pros I trust!

Dominic came out and found this intermittent leak I've been struggling to find for at least 4 years. I've been thru 3 mulligans with the local water district for high water use forgiveness. He had to escalate from the CO2 to the Helium big tank but he did find it in a place I would never have found or suspected. I dug down where he said, removed a bad buried inline valve, I didn't even know was there, capped off the pvc and the leak is gone! WHAAAAAT! Call him or his dad, these guys are pros and get the job done!

I was referred to Leak Detection Pros due to a find leak somewhere in my pool. Dominic came out ( he and his father Mark run this business with just the two of them) and went through my system thoroughly. He was able to identify two broken pipes and pinpoint exactly where the breaks were.
He is truly a pro and since they only diagnose, but do not do repairs, there is no pressure to hire them to do the fixing. (unlike other companies).
The prices were reasonable and the expertise priceless. I would highly recommend this company. They really pulled through for me.
