I had a badly blocked kitchen drain line that was causing the sink to back up every time it was used. I tried snaking the drain myself but I couldn’t clear the blockage. I got Andrew and Alex from Mister Plumber in to clear the drain and to do several other plumbing related problems (e.g leaking kitchen faucet, broken soap dispenser, checking the sewer back flow preventer) that I had been putting off. Andrew and Alex showed up at the agreed time and conducted themselves professionally and resolved all of the problems.
They also cleaned up completely after themselves.
Based on the work that they did for me I would rate them as very reliable.
