Brett and Daniel were very helpful. They fixed the problem quickly and even added some strapping under the house to keep the drain open. I recommend them highly.

Mr. Rooter Plumbing of Newberg

Was at work when my wife called in panic that all of the toilets and sinks were full. Called at 8 am on a Sunday morning and was told that they would be there around noon. Plumber was exactly on time and he was a hoot. Professional, friendly, and funny as heck. You could tell he likes his job. He fixed the issue quickly. Happy wife, happy life.
