Lem arrived on time, explained the problem, explained how he is going to fix and how long he will need. He repaired a leak in the toilet and left the place very clean. I will hire him in future for any work.

Had a great experience with LEM. They came by quickly, were very knowledgeable and were able to quickly assess what the issue was. Unfortunately, the problem was for our sprinkler company to address but I would not hesitate to call LEM again for any future plumbing issues!
