What Oshawa homeowners say
Clean, quiet, respectful
Shoe covers, sheeting, and a sealed vacuum. My wife works from home and barely noticed they were here.
Second flue done same visit
Old house with a furnace flue as well. They handled both in one visit and discounted the second one rather than charging full price twice.
Fast after a smoke back-up
Smoke came into the living room on a Sunday evening. They were here the next morning, found a nest, cleared it, and tested the draft before leaving.
Explained the pricing upfront
Quoted over the phone, confirmed on site before starting, and the final invoice matched exactly. Refreshing in this trade.
