Recommended Customer Reviews

DO NOT USE THIS COMPANY
Our insurance company recommended ALD.
The report indicated that there was a leak at the shower valves and that there was a leak at the shower drain connection.
Both were incorrect and the problem was a 1"" gash in the main drain line of the house above the concrete slab. This gash was a completely independent drain from the shower and water was flowing out of it unobstructed.
The real problem is that our insurance was not going to cover the repairs and it required completely gutting the shower. We had to pay a contractor to address what the report indicated to the tune of $2,400. Lucky for us, our contractor did not want to seal up the walls because there was far too much water remaining and nothing had dried out over 2 days.
Once we decided to investigate, an indication that there was more of a problem was the sopping wet/ rotted Sheetrock at the sink that my finger shot straight through with no resistance.... Pulled a little bit off the wall and found the gash that was the source of our water problems.
My advice: if you see water stains near your plumbing walls, just pull a little Sheetrock off and see for yourself... You are likely to see the problem, you are going to have to replace damaged Sheetrock anyway, and the Sheetrock repairs will cost you less than the ALD inspection.... AND you may save more by NOT addressing things that are non-issues.

I don't live in the area, but our family owns a rental property in Dublin and we had to file an insurance claim for a leak on the property. I talked to a couple of other companies but it was a mess trying to coordinate everything.. A friend in the bay recommended American Leak Detection and they were a lifesaver!
Everyone in the office was really friendly and answered all of my questions and their techs were awesome and really knowledgeable.
I hadn't seen some of these negative reviews before I worked with them, but I had a great experience and will call them again if I have another problem on the rental.

I have used American Leak Detection several times to find leaks under my slab home, help with finding sewer line blockages and more. They have always been very professional, respond very quickly and - they find the leak. I have used other companies (I won't name them) who leave, (leaving me frustrated, without helping me and with no hope of a call back. American Leak Detection always makes sure that they have found the source of the problem, done all necessary repairs, and have explained the process so that, if possible, I won't need to call so quickly in the future.
I had first called them years ago when there were some problems with a commercial, indoor pool that I manage. They were so quick and efficient with something that was a huge problem that I never hesitate to call them for issues at my home.
Highly recommend.

Not only did I use these guys to replace a root-clogged, constantly-backing-up, sewer line at my residence but I used them many times as a landscape architect and contractor.
As a contractor I had many jobs at old houses solving ancient drainage and irrigation leaks and problems. I had 100% satisfaction with their analysis and the recommendations. They saved both me, and especially my clients, a lot of time and money that could have been wasted trying to figure out and solve underground problems.
I was especially happy at how quickly they were able to respond to my calls, knowing that, for me, time was money, and that, for my clients, they needed a reasonably priced investigation.
I would not hesitate to continue using them in the future.

Great service, fantastic equipment, honest and professional technicians. Highly recommend!

""Leak Detection Without Destruction"" reads their brochure.
I have a leak in my pool and I found in the homes files that American had been used previously, so I called them.
Let them know that I had turned off my pool pump and sweep for 3 days and the water level didn't change. But when I run them for 4 hours level drops by about 1/4 inch.
Tech came and performed ""pressure"" testing of pump and sweep lines, which took about an hour. Then he asked me to turn on the pump and within a few minutes informs me that my pump is malfunctioning. Funny, it was fine that morning. . .
So he leaves and I have to call my pool service guy to check it out. Diagnosis is a broken impeller. 10 days to replace and part is $185 with $110 service charge.
ALD Tech returns and once again performs a pressure test and finds a leak at the cover of my pump filter. It's cracked. Funny, it was fine before. Cost to replace, $97.
And, he tells me that he found that my pool sweep inlet connector was broken. Funny, when I bought the replacement piece, cost $7, I noticed that the broken pieces are the parts that hold the hose in the connector. If it had been broken prior to the service call, the hose would not have stayed in place but would have been ""blown out"".
Then I was told that they ""think"" there is a leak in the vinyl pool lining and that I'd have to call someone else to have that checked.
Their cost: $325
Thanks for nothing. I told them that I would NEVER call them again!
They probably don't care. . .
They claim that the pump was ""old and damaged "" prior to their testing. How can they make that claim? They DID NOT check the pump prior to their testing, even though I told them that the water level only dropped when the pump was running.
I've called 2 more pool repair companies and when I mentioned American Leak Detection, they were silent. Not a good reputation in the business AND I can see why.
If you look at my reviews, I do not complain unless it is deserved.
Look, for that much money and a ""Detection without Destruction"" motto, I expect more. Check these guys out very carefully before hiring them.

Leak detection worked for me. Here is the full story:
Was having some yard work done (major) and suddenly my pool starting dropping (about 4 inches in 1 week). I tried digging up where the new lawn sprinklers were going but after a few holes I decided it was time to get in some help.
I called two places. One local company (with Leak in its name) and American Leak Detection since these are the only two companies that seem to do this type of work. The ""local"" company said they could get to my project in 2 months.. OK that isn't good and American Leak Detection said they could be there next day.
I was really worried by other Yelp reviews but what can you do when the pool is leaking and no one else can do the job.
Our technician Ken Johnson was fantastic.. He started by testing everything in the pool with some sophisticated equipment, but after 2 hours had found nothing. Undaunted he proposed we isolate pool from spa and see what happens overnight... turned out Spa was the culprit. (if it was the pool he would have dived the pool). He came back in 2 days to find the problem in the spa. It turned out to be the light. Yep behind the light there was a leak. (I would have NEVER found that, never). He fixed the leak with some epoxy, refitted the light and we are all good.
What a great experience, would recommend Ken to anyone. I am so glad I did not try to do the work myself. I would have destroyed my yard and never found the leak.

This is the third time I've used American Leak Detection to locate outside plumbing leaks over the past decade. The technician arrived on time (always a plus) and was able to locate the leak in under an hour.
I had a very slow leak in the main water supply line from my water meter. The flag was within inches of where the leak was. I hired a private plumber to repair the underground leak because American Leak was backed up in their repair scheduling. They were also going to charge me a lot more for the repair, but it would also come with a guarantee.
I would definitely use them again. The only reason I didn't give them 5 stars is cost.

I've had only good experiences with American Leak Detection. Over the last three years I've had them come out and find four leaks for me. Each time the leak was within inches of the spot they indicated. I couldn't ask for much better detection.
A number of owners in my complex have used them and everyone has been happy with their work. They're professional, respectful (at least in my area), and I would gladly use them again if I have another leak. The price is not cheap, but thanks to Yelp I got a much needed discount.

They called when they said they would to give me a 30 minute heads up on arrival, they reconfirmed the appt., showed up at the front end of my 3 hour window.
Scott had a positive attitude, and only charged me for the performed work instead of the original quote.
Followed up with a recommendation for a repair specialist within an hour of leaving my house.
