Calvin did a great job clearing my kitchen drain. I learned that I shouldn’t be putting coffee grounds, eggshells, and lots of peelings down my disposal. I also lucked out with the $75 discount through 9/30! THANKS A LOT!

Jesse and crew did a great job making a repair on the iron pipe under the basement floor and completely cleaning the sewer pipe under the house. Also fixed a problem at the city line, all in one day. Very clean and organized.

Hello all, I’m a local plumbing contractor and I refer clog pro to everyone. I had my sewer back up on my personal home Friday night, they came out Saturday before noon and took care of me properly professionally and did a great job!

Nothing but PROS at ClogPro! From the phone call to book an appointment to the house call to clear the drain. Daniel was kind, professional and eager to share recommendations on how to avoid a clogged drain in the future. Will definitely use ClogPro again, but fingers crossed I don’t have to. 😊

Clog Pro has been my go-to plumber for years. They are always very prompt, great to work with, and reasonably priced.
They’ve helped me with countless drain/clog issues, but they’re also great with new rough-in installs which has been super useful for my remodeling co. 10/10 will always go with clog pro.

Jesse Grandkoski8 reviewsiTotal number of Google reviews Jesse has written across all businesses on Google Maps, not just this one.
Firstly, my wife called many plumbers for help with our situation. Clog Pro has real humans answering the phone, their office staff was very helpful. Daniel was dispatched, and showed up with both kind and professional manner, with the right tools and equipment, and went to work immediately to diagnose our problem. He showed us with the scope what the problem was. Of course it was a bigger fix than we had hoped, and a second team was dispatched, after a thorough review of tapes and detailed report from Daniel. Jesse and crew arrived ASAP, and I was immediately impressed with Jesse’s knowledge, experience, and work ethic. At no time did these guys stand around, they work efficiently and the vibe amongst the crew was good. Without delay, they performed a major repair, using new equipment which saved us a lot of time in excavation. Efficiency and clear communication mean they’re not wasting my time and money, or the bosses. I appreciate this. They fixed the major repair and a couple of other minor issues they encountered on the way. No funny business, just getting the job done. 10/10 would recommend.
