We had a ruptured water main leaking inside our basement. We called LtP. The plumber came out a few hours later to inspect and hive us a quote. The repair work happened the next day, which was to replace some pipe, add new shutoff valves and a water pressure reducer. Everything is complete, leak free and working properly. Billy, the plumber doing the work, was very nice, respectful and honest. Everything was done professionally and in a timely manner. Excellent work.

All staff were extremely courteous, the appointment was scheduled in a timely manner.. our only complaint is the cost. The plumber arrived then left for an hour to get a pipe, worked for a bit then needed to leave again this time for over an hour for a blade- the total hour and a half of work was much more expensive - I was told since I signed off on the pricing before that’s the cost - be careful that’s were they get you. All in all the problem was resolved and I learned a lesson. I asked for a call back to discuss the logistics but never rec’d one.

FIVE STARS! I am one tough client, I believe in transparency, our two day service resolved both plumbing issues. Len Plumbing Heating & Air sent Jamarl who arrived Monday morning and was kind enough to explain step by step how our two ruptured pipes would be fixed. He provided a thorough estimate. Tuesday a team of two arrived, cleared away the affected area, removed the damaged pipes, repaired the pipe under our deck with copper, and the bathroom a mix between copper and PVC piping, and utrap. IMPORTANT: The bath has never worked better. Not going to lie my lack of knowledge caused some complications however Lens Plumbing was able to calmly explain what was done and the purpose behind the choices. Truly grateful!

Our technician James Long was awesome. He helped us get water back into our new home and gave us quotes and suggestions on what we should do to prevent it from happening. Would def recommend as he was very friendly. I would recommend to everyone.

Plumbing tech said Shower/tub diverted & plumbing install would take a day. I can't speak to the plumber’s skill because he didn’t do any plumbing. But he can do demolition. Put a hole in plaster & lathe hallway wall & left. I had put down a deposit & he didn’t do any plumbing. The company didn’t respond back to txt or call me until Monday October 13th txt saying they wanted to get me back on schedule to complete the work. The Tech was here on October 1st, and I haven't seen him since. A master plumber came today (10/15/2025) from another company and installed the diverter and other necessary plumbing features, he arrived at 09:45 AM and was finished at 12:45 PM, and while they were a little pricier than Len, I didn't have to deposit/pay a penny until the job was complete. I'm not even complaining, I'm just saying.

"I have used them for years and was always happy with them even when they would send a really young plumber and I would say “good lord what does he know?” They never disappointed, they were always really good. Then this last time when I was trying to invoke the warranty on the new toilet they installed, they sent out a guy and I told him about the leak. They checked if it was leaking and it did. There was dye coming down, and the water was draining out of the toilet without flushing and the dye was also leaking from the tank into the bowl. I told him both things and all he did was stand and stare at it for fifteen minutes, flushed it a couple of times and looked at it said nothing was wrong with it and left. Then I called, I talked to someone at Len the Plumber, and they said someone would call me back and get the details. They did, and I gave them the story this story right here all over again. That person said “oh someone will get in touch with you.” Which is what the first person had said, and I never heard from them again. They did not change the flapper which was probably all that was needed, except for the draining of the bowl which is probably some sort of valve at the bottom of the toilet. Which would to indicate that the toilet needed to be replaced, and the guy just stared at it for a long time. He agreed with that assessment, although he didn't think anything was wrong with it but all he did was stare at it and said “I have other calls today, so I'm going to go.”"

"Len the Plumber (Baltimore) was extremely expensive. It was to replace the hot water tank. The cost was $3500.00. They said that part of it had to do with Covid-19. It was a small tank, and they had to find it. It seemed expensive to me. I had water everywhere, so I had to do it. Bottom line, it was too expensive!"
