Chimney rebuilding is the partial or complete reconstruction of a chimney stack that has deteriorated beyond what targeted repair can address. It involves removing the failed masonry and rebuilding the chimney to its original profile using matched brick, correctly specified mortar, and a properly constructed crown. Stone Haven Developments provides professional chimney rebuilding services for residential homeowners and commercial property managers across Southwestern Ontario.
Chimney rebuilding is for property owners whose chimney has deteriorated to a point where repair is no longer structurally sufficient or cost-effective.
This includes:
A chimney rebuild at Stone Haven Developments begins with a proper structural assessment and proceeds through a defined scope that accounts for the full condition of the chimney, not just the visible damage.
A licensed mason assesses the full chimney from the roofline to the crown to determine the extent of the rebuild. The assessment identifies the lowest course of sound masonry that can serve as the starting point for the new work, the number of brick courses to be removed and rebuilt, any flashing or flue liner work required, and the crown specification.
Chimney bricks above the identified sound course are carefully removed and cleared. Demolition is controlled to avoid structural disturbance to the roof or surrounding building elements. Debris is managed and removed from the site as work progresses.
Replacement bricks are sourced to match the original chimney in size, colour, and texture as closely as the available supply allows. The mortar mix is specified to match the age, type, and hardness of the surrounding masonry. Material selection is a critical part of chimney rebuilding because a mismatch in mortar hardness or brick absorption rate causes premature failure. Stone Haven applies the same care to material specification here as it does to targeted chimney repair work.
The chimney is rebuilt course by course from the sound starting point upward. Each course is checked for level, plumb, and mortar joint consistency. No scaffold is removed until the full rebuild is complete and the mortar has achieved the initial set.
A new chimney crown is cast or formed at the top of the rebuilt stack using the correct crown mix, sloped away from the flue opening to shed water outward. A chimney cap is installed over the flue to prevent rain and debris entry.
Flashing at the chimney-to-roof junction is inspected as part of every chimney rebuild. If existing flashing is deteriorated or improperly integrated with the new masonry, it is replaced. Proper flashing is as important to chimney watertightness as the brickwork itself. Broader roofline or structural scope can be handled through Stone Haven’s professional construction consulting.
A full rebuild resets the maintenance clock rather than extending a cycle of recurring repairs.
A chimney that has shifted or lost brick cohesion is a safety risk. A rebuild removes the failed masonry and reconstructs the stack to current standards.
A rebuilt chimney with a properly formed crown and integrated flashing stops the water pathways that cause interior moisture damage.
A documented chimney rebuild by a professional masonry contractor is a verifiable improvement that registers positively in any property inspection.
When a rebuild is done correctly with matched materials, the reconstructed chimney performs reliably for decades.
Stone Haven Developments provides professional chimney rebuilding services across Southwestern Ontario including Stratford, Perth County, Kitchener, Waterloo Region, Guelph, Cambridge, Hamilton, London, Burlington, Oakville, and Milton.
Stone Haven Developments was founded by Matthew Howe, a mason with over 17 years of experience in residential, commercial, and industrial masonry. Every chimney rebuild is approached with the same care as any significant structural masonry project: assessed properly, specified correctly, and executed to a standard the finished result demonstrates.

A chimney that needs repair has isolated brick failures, receding mortar joints, or a cracked crown but retains its overall structural integrity. A chimney that needs to be rebuilt has shifted away from plumb, lost multiple courses of brick, or has mortar failure throughout the stack that targeted repointing cannot address. Our guide on signs your chimney needs rebuilding walks through the key indicators in detail. An on-site structural assessment by a qualified masonry contractor is the only reliable way to make this determination accurately.
The cost of a chimney rebuild in Ontario depends on the height of the rebuild, the number of brick courses to be replaced, material matching requirements, flashing condition, and access complexity. A partial rebuild above the roofline typically ranges from $3,000 to $8,000. For a broader look at what drives masonry costs across different project types, our guide on chimney rebuild cost in Ontario covers the key variables. A full chimney reconstruction from the base is a more significant project with costs determined by the specific scope. Stone Haven Developments provides a detailed written proposal after an on-site assessment.
Most residential chimney rebuilds above the roofline take two to five days depending on the height of the rebuild, the number of brick courses involved, and weather conditions. The project timeline includes demolition, brick sourcing confirmation, masonry construction, and crown work. For context on how different masonry scopes affect timelines, our guide on how long masonry jobs take is a useful reference. New mortar requires 24 to 48 hours for the initial set. Stone Haven provides a project timeline with every rebuild proposal.
Stone Haven makes every effort to source replacement bricks that match the original chimney in size, colour, and texture. For many residential properties, a close match is achievable. Our post on matching old brick for repairs explains how this process works and what affects the degree of match. For very old or historically significant brickwork, perfect matching may not be possible, but a skilled mason can minimize the visual contrast. Mortar colour and joint profile can also be adjusted to blend the new work with the existing chimney below the rebuild line.
Building permit requirements for chimney rebuilds vary by municipality in Ontario. In some jurisdictions, structural chimney reconstruction above the roofline may require a permit. Our post on masonry permits in Ontario covers what homeowners should know before starting a project. Stone Haven Developments recommends confirming with your local municipality before work begins. The team can advise on typical permit requirements based on the municipality where the property is located.
