What Customers Say
Trusted by El Dorado County Homeowners
Excellent plumber and great to work with. He replaced a toilet, installed new angle stops, replaced wax rings, and took care of several other plumbing issues for us. He was punctual, professional, and did quality work at a fair price. Everything was done right the first time, and he made sure the area was clean before leaving.

If your looking for honest hard working talented professionals. Your search is over. I had my pipes burst under my mobile home and they fixed them quickly, efficiently and at a great price. This senior citizen is very thankful and impressed. They get a 7 out of 5 stars in my book.

Jim Thorson has done the plumbing for me on two new construction homes. Both were permitted and inspected by the Placer County Building inspector. I cannot speak highly enough about the quality of work. He was a real joy to work with and always very accessible — which based on my experience with sub contractors has been rare.

Thorson plumbing responded quickly and replaced our hot water heater right away. They fixed the issues from a previous install. The attention to detail is excellent! They are who we call with any plumbing issues. You won't be disappointed using Thorson Plumbing.
