TJ from Thornton & Grooms did our annual furnace inspection on October 27. He performed a thorough check of the heating system in a very professional manner. Explained every procedure. Great job! David Rudd did a great heating inspection today, 10/22/2025,. Explained the process thoroughly, and answered every…
Ben did a great job , as we have come to expect from Thornton & Grooms. Ben flushed and descaled our tankless water heater and while that process ran, Ben installed a replacement toilet in our master bathroom. Ben explained everything that he was going to do and then went over the completed jobs when he was…
Excellent communication through the whole process, from booking through arrival and departing. Professional, courteous, thorough. Greg arrived on time, was very thorough with his inspection of the plumbing system. He replaced a couple seals, drained the hot water heater & installed a couple screws into the HW…
Very satisfied with the service provided by Charles King.
Which one of these photos shows inappropriate level attention to detail gives me concern regarding what is not directly in my face otherwise very charming and professional, but that’s unacceptable icing on the cake
Curt & Khari did an excellent job installing our new toilet. Very professional & kept us informed of any concern or problem. Would highly recommend T & G.
Great service from Jonathon Wellman and Dylan C. Very pleasant young men, competent, worked efficiently and cleaned up the area after replacing an old toilet and supply valve. Would recommend them for any plumbing repairs or issues.
Plumbing inspection
Thank you Robert for repairing our air conditioner and answering our questions. We appreciated the short time it took you to get us up and running again just in time for the warm and hot summer days. Thank you for a job well done!!
Next day service that was absolutely outstanding and seemed like it had been part of their schedule for weeks!
Needed to add freon to charge the system. They came and diagnosed the issue and promptly made the necessary repairs
Mike came out to give us an assessment and estimate for a sewer line replacement. He was knowledgeable and thorough on all aspects of the project. Jesse and his team replaced old cast-iron pipes with PVC pipes. they also replaced a toilet flange and misappropriated PVC pipes from a prior plumber into proper…
Tony is very honest, open, down to earth, professional, and competent. He is very friendly and delightful to work with. He did an outstanding job repairing a toilet leak and installing 2 brand new toilets. Next, we are going to have Tony install 2 new bathroom vanity sinks. I highly recommend Tony for any plumbing challenge you have.
Nick did a wonderful job. Very professional, definitely knew what he was talking about, and friendly. Would highly recommend Thornton and Grooms!
Quoted $4,647 to install/swap one regular toilet ($912) and install/swap one smart toilet ($2,824). Shocked by these prices. Hired a different company to do the same work for $275 for the regular toilet and $600 for smart toilet.
We’ve always loved the level of service that T&G provides, but Zeke went above and beyond! Really happy, job well done.
Tom did great work on toilet installation. He is family and took good care of us.
Friendly and professional workers
I cannot say enough of how these guys are the best plumbing service company out here. Completely trustworthy and the services techs are hands-down the best in this industry. They always have the parts that are needed so I'm never waiting to get my problems repaired. Thorton and Grooms will always be my first choice when I'm in need.
Love the people and the service. Great job installing our new toilet. Thank you! Thanks Paul!!
The work has been sloppy at best. Charged full price + for a team of people that didn't seem to know what they are doing. 5 days after 'the work' got done, we've had the laundry room flooded, the shower diverter shoots water out the back (never tested - twice), shower drain cracked and leaking, toilet not installed correctly...
Paul was the installer of a new toilet and laundry room faucet, with shut-offs. He was very courteous, neat and allowed me to ask whatever questions I had. Also was great with the dogs we have. Highly recommend him, and Thorton and Grooms, in general.
Jeremy was promt, courteous and thorough in his estimate for interior and exterior main drain replacement and toilet installation.
Great Service
First, thank you, Thornton & Grooms, for your quick response to our call for service. We called for service late afternoon (after 5pm), detailed our issues with your message center and you provided us a service technician before noon on the following day. We're floored by the speed of this. The specialist you…
Written in approximately 2017 --- I am thrilled with my experience with Thornton and Grooms...all 20+ times they've been out over the years. They absolutely have a knack for hiring the perfect service technicians. Bill Richards is our go-to guy for plumbing and Will Walker for HVAC. We've had others come out, and…
Removal of old and installation of new toilet.
Jaclyn was great and installed a new flush assistant toilet and tested it.
I very pleased with their professionalism and care for the house...very true professionalism. Just outstanding !
Sergio was great when he called about letting me know that Alex was coming. Alex gave us options on what we could do with our toilet. Alex put in a new toilet which is fantastic! Alex is informative, kind, and does great work!
Dave Laginess completed my annual furnace inspection. He was very thorough and knowledgeable and very respectful. Thank you Dave
Josh was excellent in providing options for our malfunctioning toilet. He clearly explained the work & costs for same. I hope I can request him specifically next time. Price seemed a little costly, but I think everything costs too much these days.
Always experienced and courtesy staff with good communication from techs and dispatch.
Best service ever. The guys were very helpful and kept me informed throughout the whole process. I will never call anyone else. The guys were quick, efficient, so polite and cleaned up the basement and back yard. Jonathan Wellman , Jared Edward's and their crew were the Best. And the price was great. Thank you Thorton & Grooms
Both Tony & Joshua were beyond helpful & professional. That is why I contact a bigger company I wanted the job done correctly & in time for the weekend & if by chance there were any problems I could get a hold of them again. I do not anticipate there will be any problems with the job they did. If I could give them…
Great service by Kevin Byrne!
Thornton and Grooms have become my new favorite! They are professional prompt and they get the job done right the first time! Jacob Priest performed my plumbing maintenance. I decided on a new toilet instead of a repair. Something I thought was an awesome “touch” Jacob labeled the valves in the basement so I…
Dave from Thornton & Grooms went above and beyond servicing our air conditioner. He thoroughly explained the issue and fixed it quickly. He is an exemplary example of the T&G team.
Anthony and Aaron did a good job. So did John. What I didn't like was Anthony and Aaron left and passed the job on to John. John didn't finish last night and he said he may or may not be back to finish today. It may be someone else. I don't understand that.
Dan came to my house to perform the yearly Furnace safety check. So glad I had it done. Found a leak that caused some damage to the motor. The part is still under warranty so having it replaced. If I did not do the maintenance this year, could have done more damage to my furnace. So Thanks Dan for doing a great job…
