Health Risks of Radon Exposure

Radon exposure is a leading cause of lung cancer among non-smokers, according to the World Health Organization.

I hired John the Plumber (Eric) to do a complete plumbing rebuild of the basement bathroom (+4 feet of water) after the Canada Day flood. He explained clearly what needed to be done. When Phase 1 began he showed up with student / apprentice /helper (Reza). They worked together like a plumbers symphony. They completed Phase 1 in a timely and professional manner. After doing so they explained clearly what had been done and iterated what would occur when they will return for Phase 2. I have complete confidence that they will complete Phase 2 and 3 in the same professional manner they did in Phase 1.

Booked an appointment for a few things. Eric showed up on time after letting us know he was on his way. He went over the things that needed attention and took his time to explain everything very clearly! He also suggested something that may need looking into down the road. Very honest and transparent. Would highly recommend John The Plumber. Very satisfied!
