Forget the snake! Now we have our very own Hydrojetter! Call us when you need your lines cleared out!

A hydrojetter is a vastly better pipe cleaner compared to a snake. A hydrojetter can completely remove any blockages as opposed to punching a smaller hole like a snake will. A hydrojetter also will clean the entire pipe instead of just removing blockages.

What Our Clients Are Saying

We just used Guaranteed Plumbing this past week based on other recommendations on this site and found them very helpful and reasonable. They showed up early, did the work and I thought they did a great job (they ran gas & install logs). Also, got gas logs for Patio and Fireplace.

Jacob B.

Guaranteed Plumbing (in Danville) did all of our outside work and I think they did a great job. I worked mostly with Damon and he was great start to finish.

Michael T.

…I second that - they were great and reasonably priced

Olga B.

Your service department did a great job at my home cleaning out the sewage line. The service tech had a great attitude, and was very patient as he looked for my cleanouts which were covered by landscaping. Due to your work we got things back to normal within the evening.

I am one of their loyal customers and have recommended their services to my friends because of the prompt and courteous service that their plumbing team provides and the high quality of workmanship I can expect every time.
