Sunday water heater replacement with multiple price-point options, no pressure, completed same day — cited by Amy Thomas (esqtG51ltMgVjmfEDjJ8).
1 cited review
“Our water heater started leaking and Mustafa came out the next morning, on a Sunday. He was extremely professional, honest, and took the time to walk us through several replacement options at different price points. Once we decided, he completed the work the same day.”
Multiple Christmas-week calls handled quickly including burst pipe, toilet failure, and kitchen ceiling leak — reviewer used them 3 times in 1 month (3L5r3FQMFeOxdmsBTmsJ).
1 cited review
“Called Len on a Sunday and had Dustin arrive in an hour. He was great and was able to fix the leak coming out of the kitchen ceiling.”
Tech James Milligan saved seller ~$10K by running an actual leak test rather than accepting two prior plumbers' guesses — cited by Stephen Pezzetti (x5feGoeOtQMzQi5HBDrQ).
1 cited review
“James told me although the test would cost me $309 it would be money well spent if it demonstrated there was no leak (he suspected it was not leaking). After 30 minutes of watching the meter after shutting off the main it hadn't moved. NO LEAK!”
What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
1 tech dented a new faucet and poked a hole in a utility tub during installation, then suggested customer tell Amazon it was damaged in shipping to cover the incident — management only asked for a review instead of calling back (Avp8q7ndn5scpkAIPNpx).
“The technician dented the faucet and poked a hole in the tub. He then suggested I tell Amazon it was damaged and LTP that he needed to come back to install it. I left a message for the LTP mgmt but they didn't call back only asked me for a review.”

The evidence — in reviewers' own words
Critical
“My plumber was friendly, competent, and did a good job, but the pricing was truly insane. When I talked to the office over the phone to schedule the service, telling them exactly what I'd need, they said it was a $49 fee to have someone come out and look. But when they got here, they charged me $550 to simply move the toilet and look. I should have laughed them out of the door at this point. But I didn't, and it was …”
“** Edit: Just because they left a note saying they would contact about the issues. Suprise! They never contacted me. DO NOT HIRE THIS COMPANY. I hate having to write this because they do have some very good people on staff. However, it is entirely inconsistent. Unfortunately, the incompetence outweighs the good. They padded a simple faucet replacement bill over $100 which the guy just referred to as "extra charge", …”
“I just wanted to share a really bizarre experience I had with trying to book an appointment over the phone with Len The Plumber. We have a leak in our basement and I have seen them in our neighborhood, so thought I would call them first. The interaction on the phone was quite strange. The first call dropped after I said I was having a hard time hearing the dispatch. I called right back and spoke to another person. …”
Positive
“We had a great experience with Mustafa at Len the Plumber! Our water heater started leaking and Mustafa came out the next morning, on a Sunday. He was extremely professional, honest, and took the time to walk us through several replacement options at different price points so we could make the best decision. There was no pressure—just clear, straightforward information. Once we decided, he completed the work the …”
“I was extremely impressed with the work completed by Mr Mark Martin from Len Plumbing. He was very pleasant and extremely professional. He arrived on time, assessed the plumbing issue I needed addressed, and completed the work in less than an hour. I wanted a valve to be replaced and we discussed a moving a second valve to make it more accessible. He completed both tasks and now both valves are functional and …”
