As always (we live in an old house) Knights Plumbing are our go to plumbers. Always respectful and in good moods. Today it was Victor’s turn to tackle roots in the pipes. Fast, professional and overall a great guy. He was informative without being pushy about our pipe and tree situation (we do know it’s not great) 5/5 stars. Thanks Victor

Our technician Victor did a fantastic job of running his cable and camera in our sewer line. He unclogged our blockage, fast and efficiently. He was very respectful. I would recommend this company to anyone who’s looking for plumbing services.. Leslie took our phone call and he got someone to us in less than an hour! It wasn’t expensive for the amount of work that was done .If I could give this company more stars, I would.

Michael was the service technician that helped me out and he was very thorough and neat with his work. He made sure his work was done correctly and was very communicative with his process during installation and through their office. Would recommend again.
