Ike came out to my home to investigate a costly issue. It felt more like a family member doing me a favor than a contractor coming out. Open and transparent, he asked me questions as needed, let me know what he was doing and looking for, what was inconsistent from the analysis of other companies etc... There was…

We call Heil for all our plumbing needs — and there have been a LOT in our new old home. Jake is always meticulous, reliable, knowledgeable, professional, courteous and friendly. We request him every time. Thanks for being a service provider we can trust our house to!

We had great experience with Heil Plumbing . We were dealing with a major sewage backup that other plumbers simply couldn’t fix. Damontae Tuck from Heil Plumbing diagnosed the issue perfectly. He went above and beyond, cleaning pipes in areas the previous companies completely overlooked. The problem is finally…

My basement was backing up. Heil Plumbing snaked my main drain and then ran a camera to see if there were any problems. They informed me that the clog was on the county’s property and found roots in the pipe suggesting that I file a claim with the county for reimbursement and for them to fix the problem so I don’t…

Great service! A++++++ Heil will be the only plumber we use in the future. They came the same day and had everything fixed. We had a flood and originally called Michael & Sons. They sent out a tech who was only prepared to survey the issue but he wasn’t able to run a snake or camera down the line. He said he’d have…

Highly professional, skilled, and most importantly communicated to me clearly what absolutely had to be done and what he recommended be done. He was highly skilled, detail oriented and communicative.
