What Oshawa homeowners say
Reliable across three jobs
Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.
A real person answers the phone
No call centre, no chasing. Booked in two minutes and got a text when the truck was on the way.
Bundled two services, saved the trip fee
Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.
Documentation on everything
Photos, readings, and a written summary after every visit. Makes it easy to keep records for the house file.
