Chimney inspection in St. Thomas

A chimney in St. Thomas works hardest in the coldest months, which is exactly when nobody wants to find out it is unsafe. A camera inspection now costs nothing and settles the question before the first fire.

A lot of St. Thomas homes have had an open masonry fireplace converted to gas without the liner being resized. An oversized flue on a gas appliance condenses and corrodes from the inside out.

What we find most often in St. Thomas

  • Negative pressure from bathroom and range fans pulling smoke back
  • Oversized flue on a converted gas appliance
  • Deteriorated firebox mortar and refractory panels
  • Chase cover pooling water on factory-built chimneys
  • Efflorescence and damp patches on the chimney breast
  • Crown cracking and spalling brick after freeze-thaw

What St. Thomas homeowners say

★★★★★ 4.9 average from 743 GTA reviews
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.
Kevin O. · Brampton · 2026-03-08
Good work, tight scheduling
Had to move my appointment once, but the sweep itself was excellent and the crown sealing has held through the winter with no water staining.
Greg W. · Burlington · 2025-10-21
Post-fire inspection
Small flue fire in January. They inspected, documented the damage, and coordinated the report with my insurer without me chasing anyone.
Daniel K. · North York · 2026-05-02
Thorough sweep before the season
Drop cloths went down before anything else. Room was spotless afterwards and they fixed a loose cap on the spot rather than booking a second visit.

Free chimney inspection in St. Thomas: FAQs

Is the chimney inspection in St. Thomas really free?

Yes. A WETT-certified technician attends your St. Thomas home, runs the 21-point safety check, and emails a written report with photos at no charge. There is no call-out fee and no obligation to book any repair.

How much does a chimney sweep cost in St. Thomas?

A standard single-flue sweep with a Level 1 inspection runs about $190 to $280 in St. Thomas. A Level 2 camera inspection for a sale, an insurer, or after a flue fire runs $250 to $380. Any extras are confirmed in writing before work starts.

How soon can you attend in St. Thomas?

Most St. Thomas bookings are attended within two to four business days, and smoke, carbon monoxide, or post-fire calls are dispatched same day. We call you back within 60 minutes during business hours.

How often should a St. Thomas chimney be swept?

Once a year for any wood-burning appliance, and once a year for gas as a venting and carbon monoxide check. If you burn most evenings through a St. Thomas winter, mid-season is worth a second look at the flue.

What does the free inspection actually include?

A full camera scan of the flue, creosote grading, crown, cap, flashing and chase inspection, damper and firebox check, a carbon monoxide draft test, and a dated written report with photos you can send to an insurer or a buyer's agent.

Do I have to book a repair afterwards?

No. You keep the report either way. If we find something, we quote it in writing and you decide in your own time. The $50 coupon is valid for 30 days on any chimney repair of $199 or more.
