D. Lewis Co was recommended by our new plumber - Steve from Conejo Valley Rooter, who is also an amazingly skilled plumber - to find the leak that has jumped up our water bill for the last couple of months. Jake from D. Lewis came on the day we called and did a thorough detection to find where the leak was. We know this is what they do, but we were very impressed with the work he has done for us. He found the exact spot and told us exactly what needed to be done to fix the issue. He even helped us move a couple of heavy paving tiles for us from the area. The price was very reasonable. Anyone looking for an honest, skilled leak detector, D. Lewis Co should be your first and only choice. Thank you very much! read more

When it goes wrong we know to call Drew and D. Lewis Co right away! This is our second slab leak at our home and we think Drew and his company are just the best of the best of the best! Thank you D Lewis Co!! read more

Spoke with Andrew (amazingly helpful and quite professional) who provided troubleshooting tips over the phone. Ultimately had Drew the owner visit our property. Completed a thorough inspection and identified the issue at hand within an hour. Thankful for the excellent service and expert advice. High quality experience!! read more

Tim just left my house. Not only did he help us with our issue when other companies could not, he was professional, pleasant and great to work with. Thank you for for sending him. What a pro.. Anyone with a leak problem should call and ask for him. GRess. read more

Okay here's my review that I have been excited to leave. Why? Because @first contact with Andrew in the office I had that thought (you know the one when we have when feel good about someone) "wow these guys are on it! Please be awesome because I'm tired of dealing with idiots!" Well first the owner Drew arrived exactly when his assistant said he would. I know shocker. Then the best part, Drew turned out to be cool laid back amazing guy. Again I had the thought "I hope he's good". Well he was not only good he was Amazing! He knew 5x more then every other plumber we had at the house. Long story short our ranch property is 4 acres with a lot of irrigation. The water company has been over charging us and Drew confirmed it with tons of Leak detection data. Bottom line is he ROCKED! Hire these guys! You will not regret it! Pinky swear :) read more

D. Lewis Co. provides a service that they call Utility Locating. A plumber recommended them to help us find the source of a mysterious sewage smell. I had searched the internet for people who tracked down bad smells in the area, and found nothing. I'm not sure who I would have turned to had I not found the D. Lewis Company. They can send a camera into your sewage lines to see what's up, or put a smoke bomb in there to find leaks. They also use their brains and knowledge. I was prepared for them to find a leak that would require a big plumbing bill to repair. Turns out they found my sewer vents on the roof were clogged, and they unclogged them for me. If you live in the greater LA area and you have a mysterious bad smell and need professional help to find the source, give them a call. read more

D Lewis was extremely professional. They came when they said they would and were able to detect the water leak very quickly. They are knowledgeable and experienced. Would highly recommend. read more

Drew and Andrew were hyper responsive and extremely accommodating. I highly recommend to anyone and will use again.

I work for a plumbing company and we unfortunately don't do leak detection. If we need something detected, we always call D. Lewis. We also always recommend him to our customers because we know that their locating is very accurate which helps cut costs in the long run. read more

We recently learned that we had a leak via a notice from our water company. We first contacted our plumber that was able to pinpoint the General area, unfortunately it was something that needed a leak detection company to be precise. He Suggested we call DLewis, did that and spoke with Andrew. I must say from the moment he answered the phone till the end of our conversation he was consistently kind and knowledgeable. He made our appointment within a day. Our Technician Specialist (TIM) was the BEST ... He phoned prior to his scheduled arrival time due to our dog. I must say from time of his arrival till completion, he was extremely thorough... He took pride in what he does and is also a very kind person.. very professional. My plumber was able to stop by and Tim informed him of what was happening. It's always great to do business with a company that the inside management and the actual outside service technicians are all equally knowledgeable as well as kind ..thank you read more

Once again my fellow yelpers helped me to find an honest, reliable, and professional company. A few days ago, my gardener noticed some water seeping from my front planter. I thought it might have been a sprinkler line that had cracked, but after I shut off the water supply to them, the water seeping continued. So next up, shut down the valve at my house manifold. Checked the meter, and it stopped. Okay, not the mainline. Next, check the house. I turned off all water at the numerous angle stops and made sure no appliances were drawing water and off to the meter I went. Yep. Looks like I have a slab leak. This sucks! So to yelp I go to find the best leak detection company around. And find the best I did. I called D. Lewis Co. and a very polite Andrew answered the phone. I was scheduled for the next morning, perfect! Not 5 minutes later, Andrew calls back and says the owner, Drew, will be in my area and can stop by now if it will help. Yes please! 20 minutes later Drew shows up. I brief him on everything I did, and he grabs his gear and gets to work. To say he is professional is an understatement. He took his time and located my leak with exact precision, down to the "X" marking the spot and lines for each side of the pipe. He wasn't even off by a half inch! I asked if he could help me locate pipes to help me with my decision on a repipe. He was more than happy to help. And help he did!!! I now know exactly how to run my repipe and where the pipes are located to tie into. Drew saved me time, money, and massive headaches by taking his time to help me. I cannot recommend D. Lewis Co. any higher. If you need any water, cable, gas, sewer, etc lines located, these are the guys! Honest. Reliable. Professional. Polite. Thank you Drew and Andrew. You guys are AWESOME! read more

D. Lewis Company was recommended by a plumber for leak detection. Saw the good ratings from Yelp and submitted a quote request. I received a call within two hours from Andrew who explained the pricing and services very thoroughly and what to expect. They arrived early to our scheduled appointment. They were able to determine the leak wasn't in the house and began checking the rest of the property. They found the leaking sprinkler control valve and capped it. Then they confirmed that was the only leak. I was relieved not to have serious leak that was going to cost big $$ to fix. read more

I moved out to Thousand Oaks about 5 years ago and didn't know the first thing about how to find a good leak detector or even that there was such a thing. This company was referred to me by Thousand Oaks Plumbing. Andrew called me the same day that I left them a message. He explained in detail as to their process and gave me the best and worst case scenario which I greatly appreciated. He was also very flexible with setting up an appt for me considering I have a very busy schedule. A guy named Tim came to my house to do the work. Very nice guy. He even let my puppies jump all over him and acted as if it didn't bother him. (I wouldn't blame him if it did bother him.) He was able to locate the leak pretty quickly. He gave me additional advice when I asked his a bunch of questions, which was very helpful. I paid $350 & it was all worth the money because they did a thorough job and gave me a peace of mind. I highly recommend them and will use them again. read more

Best service ever! Andrew is the nicest, most helpful person over the phone. He really listens and does a great job explaining what they do and how they do it. Would highly recommend! read more

Outstanding service. Andrew took the time to help over the phone, which led me to saving money. Ultimately he determined we did not have a leak, just by checking a few things over the phone. Thanks to Andrew we saved nearly $600... honest company and would definitely recommend! We will be using them in the future. read more

We found out the day before yesterday that we might have a leaky pipe when a representative from the water company came to the house to let us know that we had had high water usage for a couple of months. I immediately called Thousand Oaks Plumbing who referred me to D. Lewis Co to come and find the leak. Yesterday, Drew and his assistant, Jake came to our home to do their detective work. Although I didn't have any idea where the leak was, within an hour they had checked all of the plumbing in the house and found the leaky pipe. Drew and Jake were awesome and very reasonably priced. Although I would definitely call upon them again if the need arose, it is a service that you hope you won't need again. read more

Drew found the water leak using CO2 and sophisticated listening equipment -- in a place where I would never have found it, in an underground valve. What a relief! He is a real pro at locating utilities and uses radar and radio frequency detection as needed. read more

Breaking your main water line under your driveway is never a pleasurable experience but the team at D. Lewis and Co and Thousand Oaks Plumbing helped eradicate my problem in a timely and professional manner. We first called Thousand Oaks plumbing and worked with Tony who helped shut off our water main. We were referred to D. Lewis where I spoke to Andrew in the office who was able to arrange Drew to come out at 730a on Friday to help locate the leak. He understood that I had two toddlers and was going to do his best to get somebody to come out as soon as possible so we can get Thousand Oaks Plumbing and their team to eradicate the issue. Drew came on time at 730a and was off by only 9 inches which is incredible considering we had trees trimming and Santa Ana winds in the background the entire time. Larry from Thousand Oaks plumbing came out shortly after and was able to provide my family with a temporary water line which allowed me to utilize my home over the weekend. He also helped me assess a few other issues within our house that needed fixed. Larry was fantastic and I felt like he was looking out for the wellbeing by identifying things that needed to be fixed. Miquel did an incredible job fixing the main water line in our driveway only creating a small hole 2x2 hole in our driveway. It looks incredible and I am grateful that he took so much pride in his work. The office staff was remarkable as well. They were able to schedule quick appointments with the same team and in a timely fashion. I even called the afterhours line and got a call back within a few hours. I would highly recommend the entire team and I appreciate them taking the time to calm my nerves and explain everything they were doing. I hope to never see them again but if I do, I won't hesitate to call Thousand Oaks Plumbing. read more

We smelled something musty in our home so went on yelp and found D Lewis Co. Called and had the pleasure of talking to Andrew. Umm can we say patient and so awesome and so nice?? We ended up finding the obvious leak ourselves and didn't need them to come out but I still wanted to write a great review for Andrew and how wonderful it was to speak to him and if we ever need a leak detection company we will for sure call these guys!!! read more

D. Lewis Co was recommended by our plumber who does not perform leak detections. Tim just left my home. He was very professional, polite, thorough, and clean. He found the source of our leak and will provide instructions to our plumber for us. I highly recommend this company. read more

These guys did a great job! I hired them to find a potential water leak in my house and they were able to come out with just one business day notice and were very helpful. read more

I just had an unusual experience. I had called to inquire about services but did not make an appointment. I had a nightmare weekend with 2 plumbers trying to discover a leak while discovering water and mold under a linoleum floor while getting a tile job done. After having my water shut off and a lot of plumbing work done, D Lewis came out for leak detection after the whole experience was over. I did not make an appointment but for some reason they thought I had. The young man who came out was very nice and understood. I explained what had happened. He agreed not to charge me for the misunderstanding. He did take a listen with his machine to my sprinkler valves which I think was the cause of the whole problem. There was only a slight almost non-existent leak. I just wanted to say customer service like this, even for a miscommunication is rare. If and when I do need leak detection again (hopefully not!) I will definitely call D Lewis Co. After so many bad experiences with contractors this was a pleasure! Thank you D Lewis! read more

These guys are top notch. They came in and went straight to work. They had the leak pinpointed in about an hour. Drew and Jake were friendly, courteous and professional. If I have another slab leak, I know who to call. read more
