Chimney Removal & Decommissioning
When a chimney no longer serves an appliance, is structurally compromised, or is in the way of a renovation, removal is the correct decision. Done cleanly, once.
An unused chimney is not a neutral feature. It leaks water through the crown, loses heat through the uninsulated masonry chase, and introduces liability if structurally compromised.
Most Toronto homes built before 1960 have at least one chimney that no longer serves a connected appliance. When the oil furnace was replaced with gas, the boiler chimney was abandoned. When the fireplace insert went in, the original flue was sealed but left standing. These chimneys continue to deteriorate and continue to carry water into the structure above.
Removal decisions aren’t always obvious. We’ll tell you honestly whether removal, decommissioning (capping below the roofline), or a full rebuild is the right answer for your specific situation. Some chimneys are worth keeping. Others are not.
- No appliance currently connected, the chimney serves no function
- Structural compromise significant enough that repair cost exceeds the value of keeping it
- The chimney is obstructing a planned addition, roof replacement, or renovation
- Insurance renewal is flagging the chimney as a liability or requiring inspection
- Water damage traceable to an unused chimney is occurring in the attic or upper floor
- The chimney passes through finished interior space and is taking up usable area
The goal is a complete, weathertight result in one mobilization. No temporary patches, no return visits for the roof.
Assessment and plan
We determine how far down the removal goes, above the roofline only, to the attic floor, or to the basement cleanout. The structural implications of each option are explained before you decide.
Controlled deconstruction
Brick is removed course by course from the top. Specialized equipment contains dust and debris. The roof, eavestroughs, and surrounding surfaces are protected throughout.
Roof opening weatherproofed
The opening in the roof deck is properly framed, insulated, and shingled to match the existing roof as closely as possible. No exposed felt, no temporary patches.
Interior coordination
Where the chimney passes through finished interior space, we coordinate the opening and patching with your contractor, or can refer appropriate trades for drywall and finishing.

Yes, and sometimes it’s the better option. If the chimney is structurally sound and the main concern is water entry, a proper crown cap and flashing repair may be all that’s needed. If the chimney is leaning, crumbling, or causing ongoing water damage, removal addresses the root cause. We give you the honest trade-off at the assessment.
Not if done correctly. The masonry is removed to below the roofline, the opening is properly framed and insulated, and new roofing is installed over it. The visual result depends on how well the shingles match, we use material as close as possible to the existing roof.
We haul all brick and debris from site as part of the standard removal. If you’d like to keep salvaged brick for garden or landscaping use, let us know at the assessment and we’ll separate it.
Toronto requires a building permit for chimney removal in most cases, particularly where the chimney penetrates the roof and involves structural framing. We can advise on permit requirements for your specific situation and provide documentation to support the application.
A chimney that serves nothing should cost you nothing to maintain.
