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.

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

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!!
