Chimney Restoration and Repair in Denver, CO
Denver's chimneys take a beating. They're the highest, most exposed masonry on any home — fully exposed to UV, wind, rain, snow, and the most severe freeze-thaw cycling on the structure. It's no surprise that chimneys are among the first places masonry begins to fail, and among the most dangerous places to ignore when it does.
Why Chimney Masonry Fails
Mortar joint deterioration.
When joints open, water enters. When water freezes, the joint opens wider. Each cycle erodes more mortar, loosens more brick, and eventually leads to structural movement or collapse of upper courses.
Crown failure.
The concrete or mortar crown at the top of the chimney is the first line of defense against water entry. When it cracks — and Denver's freeze-thaw cycles crack most crowns eventually — water pours directly into the chimney structure.
Flashing failure.
Where the chimney meets the roof, metal flashing seals the gap. When flashing pulls away from the masonry, water channels directly into the roof and wall system. This often gets misdiagnosed as a roofing problem.
Chimney Restoration Services
Repointing and Tuck Pointing
Full repointing of chimney stacks using custom-matched, climate-appropriate mortar — with softer lime-based mixes on older chimneys to maintain compatibility with the original brick.
Mortar Crown Repair and Replacement
A failing crown gets stabilized or rebuilt depending on the degree of deterioration.
Brick Replacement
Spalled, cracked, or structurally compromised bricks in upper chimney courses are replaced with carefully matched brick — matched in size, color, texture, and era to the existing structure.
Partial and Full Chimney Rebuilds
When upper courses have shifted, settled, or become structurally unsound, we rebuild from a stable point. Far safer and more cost-effective than leaving a structurally compromised chimney standing.
Insurance and Safety
Chimney work requires working at height. We are fully licensed, bonded, and insured — including coverage appropriate for elevated masonry work. Not every masonry contractor carries this coverage. We also comply with all applicable building codes and pull permits where required.
