Excellent workmanship from individual technicians, but inconsistent reliability with quick fixes that fail within 24 hours and serious concerns about employee conduct pushing unnecessary upsells.

Critical
“This is my first time leaving an online review for a company, but I felt like I needed to do this to warn other customers to NOT go with them! Here’s my story. A very nice gentleman from Mike Diamond came to my property and immediately fixed the plumbing back-up. He said that the problem would for sure come back again, and said they could fix it for $7,500.

“This is the only professional service that I’ve ever seen that wouldn’t service because they couldn’t find close enough parking. Said they found parking 2 blocks away which was too far.

“Had someone come out to unclog kitchen sink. Said he ran 75 feet of snake out and pulled out some grease but really noted no other problem. However, he said it was a temporary fix with no guarantee and we should have them use a camera. Less than 24 hours later and the same problem is back.

Positive
“In a simple to the point review of Buster he is a honest and trustworthy plumber who made an impression on me! Rooter hero had just come to my house and attempted to scam me by insisting I need a new main line at over 11k. Buster just cleaned the line and that was almost 6 months ago with no issues!”
“I just want to take a minute to show my appreciation for Angel who visited my home today to clear 2 drains. Angel was very professional and he did an excellent job. Thank you Angel. We appreciate you. Jack”
