About Ottawa Precision Chimney Sweep
Ottawa Precision Chimney Sweep is a small Ottawa crew with ladders, scaffolding and a camera on a stick. Pierre Gauthier owns it, and most weeks he is the one who climbs up to look at your chimney and writes the price.

How Ottawa Precision Chimney Sweep Started
Pierre grew up in Orleans, in a house where French and English got mixed up at the supper table. At 16 he carried mortar for a bricklayer on a school job, and he never really got off the scaffolding. He moved from bricks to chimneys in 2006, and started his own crew in 2015 with one truck and a long ladder.
Count it up since 2015 and it comes to about 1,100 chimneys swept, 240 caps, covers and crowns put on, 140 flues relined and close to 35 stacks rebuilt. Most of those jobs were small and found early. That's the whole idea: look often, fix small, and don't wait for the brick to come down.
We work with a short list of rules. Look before you price. Write the price down. Keep the soot in the flue and the dust off the carpet. Honestly, none of it is clever, but it is more than a lot of outfits manage, and it is why our customers call us back the next fall.
What You Can Expect From Us

A Safe Roof
Scaffolding on tall stacks and a harness on every roof. Nobody skips it, including the owner.
A Clean House
Boots off, drop sheets down, soot vacuumed. You should not be able to tell we were there, except for the chimney.
Why We Climb Up First
“You can't price a chimney from the driveway. Get on the roof, look at the cap, put your hand on the brick. Ninety per cent of the time the answer is right there.”
