Experienced plumber been in this area over 30 years that i know of. had a main line stoppage and one of his workers came out and assessed the problem .due to fecal matter that my tenants put there by opening the sewage cap and digging a hole for it to fall into he could not access it(could but not easily) he ran a line thru roof access and cleared it out. this was a messy job and they were very professional anf checked all sinks snd toilets inside to make sure the stoppage was gone. the statement of cause and bill were delivered to me that same day. i was happy with the charge as well. very reasonable.they were recommended by the septic tank people and i can see why. i will be using this company again. i would refer them as well. they give excellent service.
