Chimney Services Cost Guide

How Chimney Service Costs Are Structured

Chimney service in Renfrew County is typically priced either per-job (for cleaning) or by scope and materials (for structural work). Pricing reflects travel time from service centres — providers based in Pembroke, Renfrew, or Arnprior cover a wide geographic area, and rural properties may see modest travel surcharges. The prices below reflect typical 2026 ranges for this region; costs in Ottawa or Toronto tend to run higher.

The most cost-effective approach for wood-burning system owners is to bundle chimney sweeping and WETT inspection into a single fall visit. Both services together typically cost less than booking them separately, and you get a complete picture of your system's condition before the heating season begins.

Routine Cleaning

Chimney sweep — wood-burning fireplace or stove (cleaning only) $200–$350

Chimney sweep — Stage 2 creosote (heavier buildup, more labour) $300–$500

Stage 3 creosote treatment (chemical + rotary loop system) $500–$1,500+

Gas fireplace annual service / tune-up (TSSA-licensed technician) $150–$350

Cleaning costs increase if a chimney has not been serviced in several years. A professional can assess creosote stage during inspection and quote accordingly.

WETT Inspections

Level 1 WETT inspection (visual — standard for insurance) $200–$500

Level 2 WETT inspection (includes video scan — required for real estate transactions) $400–$700

Chimney sweep + Level 1 WETT inspection bundled $400–$700

Chimney sweep + Level 2 WETT inspection bundled $550–$900

Insurance note: Most Ontario home insurance companies require a current WETT inspection report before insuring a property with a wood-burning appliance. If you are buying or selling a home, check with your insurer or real estate lawyer about which WETT level is required. Without this documentation, coverage may be denied for fire-related claims involving the appliance.

Chimney Liner Installation

A stainless steel flexible liner is the most common solution when a masonry chimney needs relining — either because the clay tile liner has cracked or because a new wood stove requires a properly sized flue. Liner cost depends primarily on chimney height, diameter, and whether a new cap and adapter collar are included.

Stainless steel flexible liner — 20 ft chimney, 6" diameter (wood stove) $1,500–$2,800

Stainless steel flexible liner — 30 ft chimney, 8" diameter (fireplace) $2,500–$4,000

HeatShield® or cast-in-place liner (poured ceramic — for compromised clay tile liners) $3,000–$6,000+

Liner work requires a WETT-certified installer. After installation, a new WETT inspection and report should be issued for your insurance file.

Masonry Repairs

Chimney cap (installed, stainless steel) $150–$400

Chimney crown repair (minor cracks, sealant) $300–$600

Chimney crown replacement (full rebuild) $600–$1,500

Chimney waterproofing (sealer applied to exterior masonry) $200–$600

Tuckpointing (mortar joint repointing) — minor $500–$1,200

Tuckpointing — extensive or full chimney exterior $1,200–$2,500

Full chimney rebuild (above roofline) $3,000–$7,000+

Full chimney demolition and rebuild (ground-up) $6,000–$15,000+

Factors That Affect Cost

Chimney height and roof pitch: Taller or steeper-pitched chimneys require more time and more complex scaffolding or roof access.
Accessibility: Rural properties with long laneways or limited roof access may see a travel or difficulty premium.
Creosote stage: Stage 2 and Stage 3 buildup takes significantly more time and materials to remove than light Stage 1 deposits.
System type: Factory-built fireplaces and prefab metal flues have different access challenges than traditional masonry chimneys.
Condition of existing materials: Deteriorated clay tiles, cracked crowns, or failing mortar joints found during inspection will add to the scope — but these issues are better identified before a chimney fire or water infiltration causes far greater damage.
