Out on the concessions a wood stove is usually not decoration. It is what keeps the house habitable when a rural feeder line goes down in an ice storm and the heat pump has nothing to fall back on, and on a propane house it is often carrying real load all winter. That changes everything about the maintenance conversation — a stove that runs hard builds creosote at a rate that makes annual sweeping a genuine requirement rather than good practice, and it puts a WETT inspection in the middle of every rural resale with a wood appliance. This page covers sweeping and inspection costs, what the WETT levels actually mean, and the permit rule that catches people out.
| Chimney sweep + inspection | $150 – $250 |
| Heavy glazed creosote removal | $250 – $375 |
| Gas fireplace annual service | $100 – $200 |
| WETT Level 1 (visual) inspection | $200 – $300 |
| WETT Level 2 (technical, camera scan) | $300 – $500 |
| WETT added to a home inspection | $150 – $250 |
| Chimney cap, installed | $75 – $900 |
| Stainless flue liner, installed | $2,000 – $7,000 |
| Repointing — partial / full | $800 – $8,000 |
| Rebuild above the roofline | $3,500 – $10,000 |
| Full chimney rebuild | $10,000 – $20,000 |

A WETT inspection is insurer-mandatory, not law-mandatory
WETT stands for Wood Energy Technology Transfer. A WETT inspection is an evaluation of a wood-burning appliance and its chimney by a WETT-certified professional, against the applicable codes and standards. Two things are worth being precise about. First, appliances and companies cannot be WETT certified — only individuals are. A company advertising itself as "WETT certified" is using the term loosely; ask which technician holds the certification. Second, there is no Ontario law requiring a WETT inspection before a sale. What happens instead is that insurers will almost universally require a WETT report before binding coverage on a home with a wood-burning appliance, and lenders often make it a financing condition. That is why it behaves like a legal requirement on a rural resale and never comes up on a suburban one.
Level 1, Level 2, and which one a rural house actually needs
Level 1 is the visual inspection: readily accessible components, clearances measured, the chimney examined from the ground. It is the normal real-estate and insurance level and it is what most quotes assume. Level 2 adds hands-on work — covers and panels come off, flue pipes are opened, the chimney is accessed at roof level, and crucially the attic is entered to inspect concealed chimney runs. On a sprawling estate roof with a long chimney chase through a deep attic, the concealed run is exactly where the deficiencies hide, so a Level 1 on that house may be answering a narrower question than the buyer thinks it is. Level 3 is invasive — walls opened, masonry or prefab chimney disassembled — and all corrective work must be finished before the appliance is used again.
Ottawa needs a permit for more than you would expect
The City requires a building permit to install a masonry fireplace or masonry chimney, a woodstove and chimney, a pellet stove, a pre-manufactured fireplace and chimney, and — the one that surprises people — a fireplace insert or chimney liner. So the common rural fix of relining an old masonry chimney to make it insurable is a permitted job, not a handyman job. Gas appliances sit in a different regime: gas fireplace installation and service in Ontario is TSSA territory and must be done by a certified gas technician, not a chimney sweep.
Sweeping: how often, and what it costs
The Ontario Fire Code requires annual inspection of chimneys, flues and flue pipes, and requires cleaning as often as necessary to keep them free of combustible deposits. "As often as necessary" does the work in that sentence: a suburban gas fireplace lit six times a year and a rural wood stove running from November to April are not the same maintenance problem. A standard sweep with inspection runs roughly $150 to $250. Heavy glazed creosote — third-degree, the hard shiny kind that comes from smouldering unseasoned wood — runs $250 to $375 because it has to be chemically treated or mechanically removed. A gas fireplace annual service is $100 to $200. Note that the Fire Code does not itself require WETT certification; that is the insurance market's standard, not the Code's.
The repairs, and why the published prices disagree
Once you are past sweeping, Ottawa cost figures diverge sharply between sources — a chimney cap is quoted anywhere from $75 to $900 depending on who you ask, and a stainless flue liner from $2,000 to $7,000. That is not sloppiness on any one side so much as the same words covering very different jobs: a cap on a single flue on a one-storey ranch is not a cap on a four-flue masonry stack at roof peak. Repointing is $800 to $3,000 partial and $3,000 to $8,000 full; a rebuild above the roofline is $3,500 to $10,000 and a full rebuild $10,000 to $20,000. Get the scope written down before comparing two numbers.
Common questions
Do I need a WETT inspection to sell a house with a wood stove?
Not by law. There is no Ontario statute requiring a WETT inspection before a real estate transaction. In practice insurers will almost universally require a WETT report before they will bind coverage on a home with a wood-burning appliance, and lenders often make it a condition of financing — which is why it comes up on nearly every rural Manotick-area resale with a stove or fireplace and almost never on a suburban one.
What is the difference between a Level 1 and Level 2 WETT inspection?
Level 1 is visual: readily accessible components, clearances measured, chimney examined from the ground. Level 2 adds hands-on inspection — covers and panels removed, flue pipes opened, roof-level chimney access, and attic entry to inspect concealed chimney runs. On a house with a long chimney chase through a deep attic, Level 2 is the one that sees the part of the system most likely to be wrong. Level 3 involves opening walls or disassembling the chimney and is ordered when a Level 2 finds something.
How much does a WETT inspection cost in the Ottawa area?
A Level 1 visual inspection is typically $200 to $300, and a Level 2 technical inspection with a camera scan $300 to $500. Added onto a real-estate home inspection as a package item, a WETT is often $150 to $250. Confirm which level you are buying, because a real-estate condition satisfied by a Level 1 will not tell you what is happening inside the attic chase.
Does Ottawa require a permit to install a wood stove?
Yes. The City of Ottawa requires a building permit to install a masonry fireplace or chimney, a woodstove and chimney, a pellet stove, a pre-manufactured fireplace and chimney, and a fireplace insert or chimney liner. The liner one catches people out — relining an existing masonry chimney so that it can be insured is a permitted job. Gas fireplaces are handled under TSSA gas certification rather than through the building permit list.
How often should a wood stove chimney be swept?
The Ontario Fire Code requires annual inspection, and cleaning as often as necessary to keep the chimney free of combustible deposits. For a stove carrying real heating load through a Manotick winter, that means yearly, and sometimes mid-season if you are burning wood that is not fully seasoned. For a gas fireplace, an annual service is the equivalent. A stove that is lit occasionally for atmosphere is a different case, but it still needs the annual look.
What does chimney sweeping cost?
A standard sweep with inspection is roughly $150 to $250. Heavy glazed creosote removal runs $250 to $375 because it has to be treated or mechanically cut out rather than brushed. A gas fireplace annual service is $100 to $200. Repairs are a separate and much wider conversation — published Ottawa figures for caps, liners and crown work vary by a factor of three or more, because the same words cover very different jobs.
