What customers say
“Tom is the best plumber I have ever used! He came in to a difficult job that had been started by someone else and did a wonderful job with great guidance. Always clean, prompt and professional.”
“Service was rendered in a very timely manner. Very professional and clean work. Very reasonable price. I would highly recommend Tom's Plumbing Service llc for all of your Plumbing needs.”
“Our new home has a well for all our water source. We had plenty of water flow directly from the well but the house water pressure was extremely low. Tom found the house had a whole house filter installed but it was installed backwards and completely clogged. I told tom I wanted the new filter system installed and the outside faucets to be changed so they were supplied pre-filter to increase the life of the filter cartridge. He did the work that only a true professional could do. I highly recommend Tom’s Plumbing Service LLC for all your plumbing needs.”
