Oct 2026 -. After our feeble attempt to fix something ourselves and spending a night with no water, once again Brian Borkowski came to our rescue. He was prompt and courteous and T-Mark was reasonable for their service call. We now have them on speed-dial (and will call BEFORE we attempt it ourselves!!) ******** We…
Plumber was fast friendly, very detailed in his explanation as to what was wrong and what my options were
Excellent work! Knowledgeable and efficient.
Fast reliable service. Very professional. Very knowledgeable. Ensured everything was taken care of before he left. Answered all my questions through out the entire visit. Arrived on time. Call ahead and let me what time they would be there.
My tech was Nick. He arrived in the time frametime quoted and was very nice, professional and informative. T Mark prices and honesty cannot be beat. My brother also used this company after getting a quote from another company insisting the pipes would need to be dug up in the basement. T Mark was able to clear the…
Don Y was prompt & efficient. Repair done well. Very nice man. Tmark did our new Boiler install & extremely impressed so called them for this smaller job as well. Definitely recommend.
T-Mark was very helpful with getting us an appointment a couple days from our call for service. The service tech arrived early and provided a thorough and detailed inspection and explained potential causes and fixes.
Was introduced to a very courteous young man named Carter who was very helpful. He explained everything and solved my plumbing issue in a very timely manner.
Incredible service. Very accommodating with scheduling. Could not be happier with the work that was done and the thoughtfulness everyone on their team showed me.
Carter was very polite, knowledgeable, and solved our sink backup issue quickly. Would highly recommend and will return for future work.
Brian Borkowski was terrific! He spent the time listening to our concerns, offering multiple solutions and completed the service. Brian went out of his way to make sure we understood each step and kept us informed. Brian was very professional and so polite to my family. Services is always above expectations. We are…
I have used T- Mark since I purchased my house 8 years ago. I have been very satisfied each and every time.
Very quick service. Diagnosed the problem and solved it immediately without hassle.
I have used T-Mark on several occasion throughout the years. They are always professional, up front about costs, and get the issues solved! Customer service is always excellent and prices are very reasonable!
Gary and Ben from T-Mark Plumbing were exceptional! They replaced and sealed an old cast iron pipe fitting and used a jet to clear a blockage. When we found an additional leak after the first job, the team didn't hesitate to come back and fix it immediately. Most importantly, they educated me on the entire process,…
Needed new bathtub fixtures. Just moving into this house and the old faucet shower head and behind the wall plumbing is terrible. The technician efficient, fast, clean, and paid attention to detail.
Derek got right to work and fixed my spigot. He explained the problem to my satisfaction.
Kole was prompt and very Knowledgeable he took the time to explain what caused the problem.
Would recommend this company to anybody that would need to have anything installed as far as heating and cooling awesome place great personnel
He was awesome, checked all my drains. Didn't try to sell me anything I didn't need. He did get a boo boo cutting a pipe and didn't even swear!!! I would have. Lol He fixed our drain and made it look shiny and new but most of all, no leaks!!!! Thank you Seth!!!
Jason A/C service tech was awesome. Quickly identified problem and had me up and running in no time. Thanks.
I could take a bath & no water leaked into my basement. However, if I took a shower, my basement got water all over it. Seth came out & diagnosed the problem & gave me a quote. He did the job very efficiently & cleaned everything up . I felt the price was very fair. This is my first time using T-Mark…
Hopefully the leak doesn't happen again!
Ben was on time. Diagnosed the problem quickly. Couldn’t have asked for more
I called in on a Tuesday evening to request some help with a water leak and was very happy with the level of service provided by the office staff. They were very kind and courteous and helped put my mind at ease. They were very accommodating with scheduling. They offered to come the next day on Wednesday but I opted…
An amazing person, fixed all the problems in the house did it professionally and in short order. Can’t ask for more than that. They were considerably less than the competition and did it a week earlier than the other company could fit us in to the schedule. The photos are of the service team repairing the main water…
I needed a leaky pipe fixed within twenty for hours. T-Mark was the only plumber I could find that could respond that quickly. Kole was professional, prompt, patient, and informative. He fixed the problem quickly.
Alex was very professional and friendly and worked hard to resolve any issues.
Jason was great! Very informative, answered all my questions and very professional and helpful! He did a amazing job!
The way Ben detected the situation I really appreciate. Very professional & high quality observation.
Also installed nre bathroom vanity. And, a utility tub hookup to washing machine.
great service, Mike is a good dude. Honest A/C service
Exceptional service thank you so much for your response. Seth was very accommodating when I asked questions. Love those blue and red trucks it was what inspired me to call you. When I saw two on one day that was when I made the call. Go T Mark!
Jon was very nice and helpful!! Great personality
Technician was kind and very responsive! Work was quick and great.
Nick arrived on time. He was able to locate an upstairs bathtub leak. He repaired the leak in under an hour and cleaned up after work was completed. I would recommend Nick from T-Mark for plumbing repairs.
Brian is the best. He has gone above and beyond for us. I can’t tell you how much we appreciate him and everyone at T-Mark. Highly recommend!
T-Mark did an excellent job on multiple services for me. They installed a tankless water heater, replaced all of my galvanized pipes that were corroded and rotting through, and also swapped out a toilet that cracked. I was very happy with the sales people (Justin and Anthony) and the technicians that performed the…
On time and friendly service, resolved the leak quickly
Happy! Jon replaced some poorly installed kitchen drains. The improvement in quality is obvious. Rocking toilet reset with better connection. All flowing smoothly and no more leakage!
Jon Stachura is the best plumber! He is courteous and professional. I received a great service! Great communication and notification. I was informed all the time about my appointments and technician. It was absolutely stressless. I would definitely recommend T-Mark to my friends and neighbors. What a great…
Gary was very professional and he got the job done in a very short time. Also very reasonable.
Alec and Murph provided exceptional service from the moment they started the job to the end. They called when they were on their way to my condo to give me a heads up and confirm the project: replacing my furnace and air conditioner. I went to work while they were performing the installations and, when I arrived…
A lot more prompt than who I normally would use. Had an apt within 24 hrs to fix the leaking condensate motor on the a/c, & didn’t have to pay an emergency fee. Guy was polite & informative. He did not do both a/c & plumbing issues. So, I couldn’t tackle both plumbing and a/c matters all in one visit, which is fine…
Craig did a great job. They fixed a leaky pipe quickly and professionally. They left the job site cleaner than when they arrived. Excellent work!
Would absolutely recommend this company and their services! Really helped us out in a bind! Great people, Ken!
I always have a great experience with T-Mark! Pat is always very friendly, professional and knowledgeable and always does a great job!
Liam was knowledgeable, professional and kind. He explained all of the work that needed to be done before he did it and answered all the questions I had.
There was a leak in the wall of a building being renovated and Craig Moeller showed up at 9:00AM, cut the wall open, removed the cracked cast iron pipe and replaced it with plastic pipe down to the basement. He was finished by 1:00 and cleaned everything up. He did a great job and the disruption to the commercial…
Brian was great, gave good direction, as we need new faucets!!!
Keven Allen did an excellent job. He addressed our plumbing need quickly and efficiently. I would definitely recommend his services.
Pat was great, on time and very efficient and knowledgeable about what needed to be done. Couldn't ask for better service!
