Celebrating 85+ years of service in the great state of Michigan

They were kind, patient, professional & thoroughly explained everything…”

"Thornton & Grooms handled our plumbing when the sump pump backed up. Bruce & Jim were our plumbers. My father-in-law, who kindly handled the appointments as I had to work, was so impressed with them. He even got their cards for his own future service needs and to recommend to others.

They were kind, patient, professional, and thoroughly explained everything. This is huge because we are not from MI and know 0 about basements. Jim was so wonderful. He even called us after hours to make sure we could book an appointment to fix everything.

I am extremely grateful to Thornton & Grooms for their thorough job & commitment to excellence. Additionally, the entire process of booking an appointment was awesome. They were kind on the phone and extremely communicative. When I called back or responded to an email/call, I got a real, very helpful person. Their automated text system lets you know when the technician will arrive and is accurate, like, down to the minute.

Super duper highly recommend!"
