Thomas did a fantastic job replacing the galvanized plumbing in my older home with PEX. He was punctual, professional, and took the time to explain everything clearly. He provided a fair estimate, carefully checked all of his work, and stood behind the job from start to finish. I really appreciated his honesty and attention to detail. I highly recommend Thomas!
