"I was referred to this company through HomeServe. I had a severely damaged basement pipe that ran to a second bathroom of ours. Not only did Paradigm Plumbing figure out the problem on the spot, they were back in 24 hours with everything they needed in order to complete the job. A problem that was bothering me for months they had figured out in 24 hours. I could not be happier with them. They have incredible communication, were very timely and protected everything that was outside of the bathroom they worked on. I can't recommend these guys enough."
