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
$600 billing overcharge reported on Yelp (cWn17GTXHwkcRT1aBuVA) with delayed refund; same reviewer later treated rudely and never received callback for a water heater emergency. Pattern of post-dispute service degradation.
“Over charged me by $600 and I had trouble getting my money back....took a long time. Foolishly, I tried calling them again due to a emergency (no hot water) and was treated rudely by the person on the phone and never got a call back as to whether or not they were coming.”
Red flag
Failed drain repair: problem returned within 30 minutes of 'fix'; second technician dispatched also could not resolve it (yelp review 95oNhlxlyqjwSNsNf18x).
“Beautiful words, poor service! I saw their fliers every where and called Len to fix my drain problem. They said that the problem was fixed. However, we found within half hour that the problem was still there. Len sent another technician back and he could not fix the drain issue and left.”
Drain problem declared 'fixed' by first tech but still present within 30 minutes; second tech sent also failed to resolve it — customer had to hire a third company.

The evidence — in reviewers' own words
Critical
“Beautiful words, poor service! I saw their fliers every where and called Len to fix my drain problem. They said that the problem was fixed. However, we found within half hour that the problem was still there. Len sent another technician back and he could not fix the drain issue and left. After waiting for several days, we had to find another plumber to fix the problem.”
“A tech came out to fix a leak in the HVAC they installed less than a year ago. He could not get ahold of his supervisor to order the parts to fix the problem and someone was supposed to follow up with me. It's been over two weeks and no one will return my calls as we continue to replace a bucket of water from the leaking pipe.”
Positive
“Mama did a fantastic job. He is very professional and knowledgeable. He fixed my issue quickly and efficiently. Very kind and easy going to work with. If I have any more issues I will definitely call Len the plumber. I had a major sanitary drain line clog along with a garbage disposal issue, and I couldn’t be more impressed with the service I received. He arrived promptly, quickly diagnosed the problem, and …”
“Len The Plumber helped us during a heat emergency and worked an absolute miracle! In a few days we had a new system installed and working on the weekend. Excellent job and very professional. I recommend Len The Plumber for all your HVAC needs!”
