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.

I have used T- Mark since I purchased my house 8 years ago. I have been very satisfied each and every time.

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,…
