American Leak Detection of the North Bay & the Peninsula

We had a leak in our kitchen area. We have a concrete slab foundation with radiant heating lines going thru it. There are all kinds of information out there on how to go about this, and what to worry about. But in the end we went with American Leak Detection to at least understand where the leak might be. They detected the leak in a completely different place to a very high degree of accuracy with their pressurized gas testing. They put a sticker, and I think the leak was right below it. Pretty amazed at this. They suggested a couple of options to fix it (leak-by-leak by drilling thru the concrete) or do additional manifold testing. We went with the leak-by-leak repair option knowing the risk that there may be other leaks uncovered after this. But luckily after this one was fixed, it was

American Leak Detection's service out of the North Bay location is first rate. I had a nasty leak in my concrete foundation. Trevor and Greg located the leak - with some extended effort - and provided a solution. These guys were friendly, efficient and very helpful. At a time when outstanding service is very rare to experience, I am so grateful for the terrific service I received from American Leak Detection. I highly recommend them for any issue, from simple leak isolation, to complex jobs requiring creative, out-of-the-box thinking.

We had an excellent experience with American Leak Detection today. Jonathan Law came out to our house and was absolutely fantastic. He was professional, communicative, and incredibly fast. Within minutes, he had isolated the exact location of our leak, clearly explained what he was doing, and gave us confidence in the next steps. The entire visit took just 15 minutes, and he made the whole process seamless and stress-free.

American Leak Detection first found the source of our plumbing leak and gave remedy suggestions, then they also came back the next day to replace a malfunctioning pressure relief valve. Both techs (Jonathan and Trevor) were professional, efficient and friendly. Highly recommended service providers.

This review is a continuation of our earlier post regarding the unprofessional conduct of an ALD technician and the continued harassment that followed. Our initial feedback was written responsibly — to alert ALD’s management to serious lapses in service quality and professionalism within their local team, and in the genuine belief that it would prompt corrective measures to protect the ALD brand and future customers. Instead, what we have faced since then is a chain of coercive and intimidating communications — including demands for payment of a disputed $250 invoice for a service never rendered. When ALD requested a discussion and review removal, we clearly informed them we were overseas until 11/27/25 and available to connect after 11/28/25. Despite this, during the Thanksgiving–Black Fr
