They call themselves the ""two brothers and the other,"" and they are proud to continue a tradition of putting the customer first.

Our guiding principles:

Mike: We can handle customers' heating services or plumbing repairs, but if they aren't satisfied, what was the purpose of the repair? We focus on building relationships; we want to resolve the issue while also caring for the people involved.

Dave: We acknowledge our imperfections; we make mistakes, but the most important aspect is our response and how we treat our clients. That’s something we take pride in.

Matt: Our core aim is to cultivate lifelong clients and passionate advocates. I think the best way to accomplish that is by always doing what’s right, no matter the situation.

Their work may be of the highest quality, but their prices are way, way out of line. If you're thinking of hiring them, make sure you get a second quote before you have them start. I agree with Mandy. Their first priority seems to be ""sales.""

I am so appalled at this company that I had to write a review to warn others. This company resembles their equipment..... Snakes. Very professional service, but they are salesmen not plumbers. I had a sewage back up earlier this spring. They came out and said I needed my pipes jetted in my kitchen. Ok fine. Then they said that they reviewed my pipes with a camera and they were corroded and I needed to dig up my basement and replace 30' of pipe.... $7000. Of course I called for a second opinion. The first company I called started laughing and said, ""I can tell you right now you weren't talking to a plumber."" Next, I called Nelson Brothers of Royal Oak, who I will give 5 stars to. They came out and ran the camera through the pipes and went foot by foot showing me the pipe and said not only was there not an issue, my pipes actually looked very good. I can't stand companies that take advantage of people like this. Now, they do very good work. I will say that, but obviously they are trained to upsell completely unnecessary work. They lost my business.

We hired the company to diagnose a problem with a tankless hot water heater.
We were charged $266 for the diagnosis and we were told the repair needed would be $1600. We got a second opinion. The repair suggested by Thornton and Grooms was not needed and would not solve the problem. The second plumber diagnosed the problem for free and correctly repaired it.

Too Late, We Got Your Money...
Gas valve handle on our fire place was sticking out too far, thought I needed to move the gas line so called Thornton & Grooms and explained I probably needed a gas line moved. Tech came out, told him I thought I needed a gas line moved. He inspected it and quoted $330+ to ""do the work"", screwed in the collar for the handle but did not open or move any gas line, was done in less than 10 minutes and left.
The tech ""forgot"" to tell me that all he was going to do for $330 was turn a collar a few times because then I would have just paid him the service call and done it myself.
What's particularly frustrating is that the tech's service report shows what he did, and it took 2 calls to the office before they even looked at the report.
Then their response to me was that it was ""too late"".
I have run into bad techs in the past but their company's management has always made it right.
Thornton & Grooms seems to know they have dishonest techs and they take advantage of it.
I would strongly recommend everyone AGAINST USING Thornton & Grooms.

We called Thorton & Grooms to come out to give us a second opinion on a plumbing problem after the initial plumber recommended a very costly, very destructive drain repair for our backed up sewer pipe. T&G assessed the situation (using superior technology to the first vendor) and had a different recommendation. They felt that jetting the line would give a clearer picture of what we were really dealing with and would most likely be all that was necessary. We went with this option, and the pipe looks fine! The price included a no-clog guarantee for 2 years, which gives us great peace of mind. We are so happy they took the time to fully explain the situation and our options, and that we were able to make an informed decision that did not cause costly, unnecessary destruction to our yard!

I used the online scheduling system and If I hadn't also called I doubt they would have honored the appointment I requested. The operator took some time to find my e-mail. Then the repairman wanted over $200 to do an ""extensive diagnostic"" on our furnace to determine the problem. He recommended a new furnace at an average of $5000. I told him I wanted to talk to my husband but that we'd like him to do a tune-up of our second furnace which he said was worse off than the first furnace, all the while trying to sell me their ""Preferred Customer Plan"" at $275 per year for a 10% discount on repairs. I asked him to just to a tune-up of the second furnace. He said it would be $800 and at this point I'm feeling terribly pressured and okay the charge. My husband exploded when he got home. We called a different company, Zilka, for the first furnace which he repaired for $135 by reattaching a loose wire on the thermostat.

I'll never recommend Thornton and Grooms nor will I ever use them again. They used to be located right in our neighborhood but sold out and the new company moved to Farmington Hills with salesmanship more of a priority than quality repair work.

While they may not be the cheapest on the block, they do good work. Used online scheduling system this morning 10/1/12, to schedule an appointment. for today or tomorrow. They called me within 30 minutes and told me someone would be out between now (this was about 10) and noon today. Sure enough, they called and said he would be out about 11:30. He was able to diagnose both of my issues and proposed an estimate and was able to resolve my issues right then and there. He was friendly and knowledgeable. Would recommend them!

Ted P. came out last week to do the a/c tune-up that is included with my Comfort Plan. He did a thorough job starting with a great question, ""Are there any areas of your house that aren't comfortable."" Without that question, I wouldn't have said, ""Oh..yes...my kitchen and great room aren't cool or warm enough."" He discovered some duct work that had never been installed correctly thirty years ago and returned to fix it. The rooms feel better already. Thanks, Thornton % Grooms!
