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!!!

We were fortunate to have gotten this company's name from the plumber who eventually did the pipe work. He called when he said he would, and arrived at the time he also said. Drew electronically diagnosed the issue within an hour. There was a leak located in our foundation between the water heater and the area of water destruction. He marked the spot and wrote notes on the concrete for the plumber who would do the work. Thoughtful (took his shoes off at the door), expedient (no small talk), and perceptive (listened to our story, then knew exactly what to do). I am happy to recommend him to any friends in the area and will keep his card.

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.

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.

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.

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.

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.

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 :)

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.

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.
