The leak detector that came out was quick and professional. Everything about this company is very professional and I would recommend them.

I kept hearing the sound of water rushing in our kitchen. After walking outside, the culprit was found - a leak that was running from the kitchen sink pipe to the outside. We called our usual plumber, Dirk, and he referred us to American Leak Detection. Matthew Graham (Matt) showed up 10 minutes early and got right to it. A couple discovery holes were required, but he found is quickly. Even though he wasn't scheduled to fix it, he said he was going to get it done today. After three hours, we were good as new. His work was so clean and he was a complete pleasure to speak to. He explained everything as he was repairing and gave us options to make decisions. He wasn't rushed or sloppy. He was a total dog lover and was polite as can be. I was impressed with his expertise and knowledge as well - he's not a one trick guy. He has extensive experience and brings it to his troubleshooting. I would HIGHLY recommend this company and will use them again. read more

"American Leak" did the slab leak detection on my house on 9/5/2025 and emailed me the report. However when the repair company dug the driveway the whole morning on the location as suggested by the report, No pipe was found. What a waste of money and time! I tried to reach them by email and phone, no response. Very disappointment by their detection. read more

Phenomenal company. Particularly the Covina branch. Honest good people who don't take advantage of customers. I've used them several times on my house that has had a ton of slab leaks. I'm always amazed at their ability to find the leaks and have minimal wall intrusions to fix it. read more

wow. this plumber spent very little time trying to assess how we had water gushing out our ceiling and determined it came from a one inch missing caulk on the outside of the tub. Impossible. We hired another to come and within 30 mins figured out the issue. Due to this young kids inexperience... our insurance claim is not fixing the ceiling. Beware if your insurance uses them. Maybe they are in cahoots? Really disappointed with all parties involved. His assessment doesn't even make sense. read more

Everyone from Barbara (?) , initial call as very professional and helpful. Sam (?) came out quickly & found the small leak in my pool skimmer, right away.

We have a very old pool. probably at least 60 yrs old. It was leaking water. American Leak detection was referred by our pool serviceman.

I was very impressed with Aaron. He is hard working, meticulous about his work, very detail oriented and extremely personable, Overall, I'm very satisfied with the work that was done/ read more

Using American leak detection proved to be a very satisfying experience. Starting from my phone call to the arrival of the technician, everything was professional, courteous, and positive. I was worried about my pool leaking, but Danny, the technician, handled it with such care and concern that I felt completely confident in his work. He was friendly, patient, and thorough. He explained the problem clearly to me. My pool cleaner told me that this company is the best, and he was sure right. read more

I wanted to take this opportunity to commend Aaron. Aaron worked on our property to identify and fix a leak. He was professional, knowledgeable, friendly, and punctual. He communicated updates clearly, and he performed his work with a bright and positive attitude. After experiencing so much hardship throughout a kitchen leak, it was a relief to have a positive experience working with Aaron. I truly appreciate his professionalism and positive attitude.

A copper pipe sprang a leak in the concrete slab that is beneath my wooden kitchen floor. Oh, joy. I envisioned the wood being ripped out, jackhammers tearing through the concrete, chaos. American leak detection sent Ramiro out the next day. He expertly found the leak with high tech listening devices very quickly. He then determined what we would need to do to fix it. No wood ripping no jackhammers. Now, I am an honest guy and the leak was not fixed by magic. Ramiro did have to cut through some drywall in our family room, under our kitchen sink and in our laundry room to precisely determine the path of the hot water from the water heater to the leak. Once he did that, he knew what to do. We made an appointment for Ramiro to return to do the repair. In short, American Leak detection runs a sturdy 200psi plastic pipe THROUGH the damaged copper pipe and makes new connect connections at either end thereby bypassing the leak. Bingo. Leak is over. Hot water flows to where it's supposed to. Showers, laundry, dishwasher all running leak free. That being said; I will have to have some drywall repaired and repainted. I will have to have some boards in my kitchen and hallway replaced because the hot water warped them, but no searching for a leak with jackhammers! Got an elusive destructive leak? Call American Leak Detection. They are prompt, efficient and effective. No baloney. They ain't cheap, but they are reasonable. Ask for Ramiro. He knows his stuff! read more

Just got off the phone with Melissa in the Covina office. Remarkable customer service. We have a leak -- only a small idea of what it could be. Melissa calmly walked me through a process of finding the source over the phone -- including using a GPS map to guide me over the phone. We found it and saved both $$ and time as we look to fix the issue and rescue our water bill. Thank you, Melissa. You are wonderful at your job. Jack MacKenzie read more

Our water billed had doubled and it was suggested that we call American Leak Detection to help with locating our leak. Aaron and Ramiro came out today and found three different problems. They were professional and helped us identify the leaks in a timely manner. read more

Very rarely do you find an honest company. Melissa was amazing. She could have just charged me for the service I requested and sent someone out. Instead she explained to me that a different solution was best even if it meant they wouldn't get the business. Amazing company. Keep up the great work guys. read more

We had a leak in out old pool system. My pool guy recommended American Leak Detection who came out and found the leak. They were hired to replace the skimmer and the leaking line and were not cheap - $3500 for a day's work for two guys and a couple of hundred at most in materials. But I have an old pool and somewhere long before we bought the house, the bottom drain had been removed leaving the skimmer as the only inlet to the pump. The difficulty is that should the water fall below the skimmer, the pump dries and and burns up and destroys itself. For safety an equalizer was installed, this is simply a piece of 2" PVC pipe that goes into the skimmer chamber about a foot below the skimmer level. This gives about a 1 foot safety margin in the pool level that once saved my butt when an old pool guy left the pool siphoning too long and drew the level below the skimmer. My problem is that when American Leak Detection replaced the skimmer, they removed the equalizer thus removing this necessary safety feature. When I pointed this out they said that putting it in would cost another $3500. Bullshit. It would have entailed about one foot of 2" PVC punched into the plastic skimmer housing - $2 of parts and ten minutes of work as the hole was already there so that the pipe just needed to be threaded through. I guess life will be OK as long as no other mistake lets the pool level fall. But they removed what I consider to be an essential safety feature without clearing it with me ahead of time. Garret and Aaron seemed like good guys. read more

Matt Graham is the best. He found and fixed the leak no one can for my mother-in-law's pool. Very responsible unlike most people. He's worth every penny to take care any of your plumbing problems. read more

A few years ago I had a leak and I called them and they found the leak right away I called them back again because noticed I am losing water they send 2 guys out and they can't figure out what is the problem so they come back out today now these are two other different guys and these guys find the problem and said I have a crack on my pebble why couldn't they tell me this last week the first time they came out what a scam they charge 550 I honestly don't think they should be charging that much it's not my fault the first technicians could not find the problem just a scam to get more money out of you. Do not call them they were not good and just make an excuse to come out the 2nd time to charge you more read more

I had a pool leak and they came just spent around determined it's skimmer leaking for 40 minutes and offered me an amount to fix the leak. I found a better price to fix the skimmer. After the fix, the pool still leaking and then I called them they wanted me to ask the repair person to detect the portion and promise will contact me regarding their detection methods. I didn't receive their call and the repair guy found out it's the drainage pipe leak. Which I asked them when do the inspection if it's possible the main drain leak and they said really it's RARE and didn't inspect it!!! They charged me $300-400 for their service and spent another $250 for another leak inspection. Definitely don't recommend read more

I have used American Leak Detection on 2 occasions. The first time was great. This past experience not so great. We are purchasing a house and the inspection was in a week. We had a leak in the kitchen under the slab. The following photos show the mess were left with , 4 days till our appraisal. Broken tile, hole in the sink cabinet bottom and hole in the wall under the sink. The leak was fixed and they just walked away. I spent the past few nights after work trying to find matching. Nothing close. Of course insurance didn't cover the $1700 repair plus paying somebody else to fix their great leak detecting. Thank you American Leak Detection! Never again. read more

Aaron came right on time. He was very good and knew what he was talking about. Took his time, was very polite and did a great job!!

The water level in our pool was dropping. Every morning we found that level was about 2 inches lower than the day before. I felt like the boy in Hans Brinker, "Just as he was bracing himself for a run, he was startled by the sound of trickling water. Whence did it come? He looked up, and saw a small hole in the dike... The little hole, if water were allowed to trickle through, would soon be a large one; and a terrible inundation would be the result." In this story the boy saved Haarlem from being flooded by sticking his finger in the dike plugging the hole. Right now, I needed someone to save our backyard from a terrible inundation and sticking my finger in a hole was a creative solution, to be sure, but not one that I felt was practical in our current situation. I asked around and was referred to American Leak Detection. After checking their ratings, I called and they were able to come out to our house for their diagnostic test within a couple of days. The leak detection specialist was prompt and friendly on the day of the appointment. The testing was thorough, involving every potential point where the leak could be originating. Our leak was determined to be in the pipe leading from the skimmer back to the pump. We were given a quote on the price for American Leak Detection to fix our problem. The estimate projected about one full day of work to patch the hole in our dike. I asked and was told that if the amount of work required to fix the leak was less than their estimate then the price would likely be lowered but the price would not be higher even if the work was greater than what they anticipated. The validity of this assurance was put to the test in our case. The first day it became apparent that the leak was in a pipe that was unexpectedly found to be encased in concrete. Four full time days of work later for multiple workers and our leak was finally fixed. The work involved not only releasing the offending pipe from its concrete encasement and patching the leak, but also opening a large portion of the pool deck to obtain access to the affected pipe. After the pipe was fixed and the whole system tested to confirm the leak had been eradicated, they expertly reconstructed the pool deck leaving an unblemished surface when they finished. Throughout this ordeal, the workers from American Leak Detection were unfailingly polite and diligent in their pursuit of the chink in our pool's armor. In the end, our leak was fixed and true to their word they stuck to the original estimate despite the significant amount of extra work that was involved in our repair. American Leak Dection is a great company with high integrity and superior customer service. I hope we never develop another leak, but if we do there is no other company that I would consider to do the work. read more

American Leak Detection - Plumbing Near Me - Covina, California

I highly recommend american leak detection. They're honest, professional and budget sensitive. My house had an unknown leak somewhere between the drive way and the house, about 300 feet. It was discovered during Xmas so I received a notice from water company. Unfortunately, no one was available and the leak is unknown. So my friend recommended me american leak and Barbara was super helpful and even recommended me to contact my builder first. After unsuccessful attempt to contact my builder, I called back Barbara and she schedule Jim to come out and take a look. Yes, it cost $375 for their leak detection and over $100 an hour after first 90 min. Jim was professional but was unable to detect the leak. He told me he will come back again and should be able to locate it with another help. However, he was very courteous in recommending me to try contacting the builder again since it should be covered under the warrantee. He said if it means cancelling him, he will be happy for us even though he did work for nothing. I followed his advice and tried contacting the builder after the New Years and they did respond. I called back and cancelled the second appointment and Barbara was very gracious over the phone. It took over 7 hours for the builder to detect the leak some 250 feet away from my house and eventually fixed it. But I felt the need to share this experience about this honest company. Thank you for attempting to help me and reassuring me during the busy holiday season. read more

Very thorough test of our pool and spa for any leaks. No leaks! Yay! Needed to get this done to rule out to that the pool or underground equipment is not the cause of an above ground issue. read more

I was dissatisfied with their service. Technician seemed unmotivated as I was required to pay for the visit anyway. I practically had to beg for him to listen to where I heard the leaking noise, and he made no attempt to look under the house where it was wet. He turned off a valve, which stopped the water from rushing but in doing so stopped part of the property from being irrigated. He did not do the work required to detect a leak, and spent much of the visit looking for his mislaid glasses, but charged for the time anyway. I would not call them again. read more

After noticing a small leak on my carpet I called a leak detection company and they insisted that my leak was from my sewer pipe under the concrete slab. They were going to jackhammer my slab to get to the alleged leak. They quoted me $4,000.00 to do the repair! Thankfully I called American Leak Detection. Manuel came out to my home and found that my leak was from my shower valve and not from the sewer pipe in the slab. The men wore masks and boot covers. My leak was detected and repaired at a total cost of only $425.00! They did a great job of clean up! I have been in property management for over 40 years so it takes a lot to impress me. I would not hesitate to use them again and I highly recommend them! 5 STARS!! read more

This is an A+ company in my eyes. I called last week and spoke to an ever friendly and knowledgeable woman named Barbra. I told her my suspicions of a leak I may have and she walked me through the steps I needed to determine if it really was a leak. Unfortunately it was so she quickly made an appointment for the guys to come out at inspect. I had Jim and Matt come out. Very professional and courteous. Found the leak and suggested what my options would be. They didn't hassle me or pressure me. They are both very knowledgeable and helpful. They even unfroze an outdoor pipe I don't even know I had. I will definitely recommend this company to friends and family. Thanks again, American Leak Detection. read more

They were responsive & accommodating. Fast, efficient & provided update as they worked through the issue. Would definitely recommend!

Auggie came to my home on two separate visits to determine the source of a leak that was causing a growing eruption on the living room ceiling. He knew exactly what he was doing and was extremely efficient and very clear in explaining what he was doing. We were impressed with his technical knowledge and his people skills, and felt confident that we were in good hands. I would use American leak Detection again for sure (but hope I don't have to!). read more

5 stars is an understatement. I have used American Leak Detection twice and this second encounter was just as great as the first. Chris came to our house and helped put our mind at ease with an issue we have had on going. His experience, kindness and professionalism was 5 stars. They are honest reliable and helpful beyond words. Melissa on the phone is wonderful as well. Helpful experienced people with no sales pressure what so ever. They do the job needed. I will be using them again if ever we need anything involving leaks or drain lines. I can't speak highly enough. read more

Very knowledgeable, sold work, quick response. This company got us out of a bind with a foundation slab leak. We are very satisfied with the work read more

WORST EXPERIENCE EVER! Long story short. The lady on the phone assured me that their guys are great at finding the leak with a special equipment. The leak wasn't where they said it was after digging through the tile. They wanted to make more holes. I said no. He wanted to charge for the digging. I refused because the leak wasn't where he said it was. The whole thing turned ugly from there. I hired another guy after that, he listened for the leak through the screw driver and found the leak! He charged much less for the detection AND to fix the leak! read more

We had a leak under our tile and concrete slab in our pantry. Our plumber recommended American Leak Detection to help determine where the leak was coming from so that we didn't have to tear up our entire floor and concrete slab to search for it. After their visit, and $375, our plumber came back to fix the pipes. He was stunned to find a few tape "X"s which were no help to him at all. Our plumber was very disappointed as well, in the lack of detection. read more
