When it comes to plumbing, Mr. Rooter is the one to call. Our trained and knowledgeable staff makes your satisfaction our main priority.

"The $7,000 project ended up costing us $123,000 because they dry-cut through the slab in our family room releasing asbestos dust throughout the entire house causing us to have to live in a Hampton Inn for 43 days. They cut the slab without supporting it and it collapsed enough to cause our brick fireplace face to have several cracks in it. With all the repairs we had to have done, the asbestos abatement project and replacing all our clothing, betting and some furniture, and with the amount our insurance company shorted us, we lost $43,000 of our retirement savings. Avoid this contractor like the plague!"
