About This Service
Individual bricks fail before whole chimneys do — faces pop off from trapped frozen moisture, edges crumble, cracks split units in two. Brick replacement removes the failed units and sets matched new ones, stopping a localized problem before water uses it as a doorway into the structure.
The craft is in the match: size, color range, and texture, plus a compatible mortar so the new units and old wall age together. We keep relationships with regional brick suppliers precisely because 'close enough' looks like a patch and correct looks like nothing happened.
Signs You Need Brick Replacement
- Brick faces flaking off and collecting on the roof or ground
- One or several visibly cracked or hollow-sounding bricks
- Soft, crumbly units you can scratch with a key
- A previous repair done with obviously mismatched brick

How We Approach Masonry Work
Assessment with photos — you see exactly what's failing and why before any quote.
Failed material is removed to sound substrate; nothing gets buried under patches.
Repairs use matched mortar and units, tooled to your chimney's original profile.
The work area is protected with water repellent so freeze-thaw doesn't restart the cycle.
Why It Matters for Safety
A deteriorating chimney is a falling hazard above and a fire pathway within: open joints can expose framing to flue heat, and loose masonry sheds onto roofs and walkways. Structural chimney work isn't cosmetic — it's the building's tallest, heaviest, hottest component being kept trustworthy.
Maintenance Tips From Our Technicians
- Glance over exterior masonry each fall; sandy joints and flaking faces are early flags.
- Keep sprinklers from wetting the chimney — chronic wetting accelerates every failure mode.
- Re-apply breathable water repellent roughly every ten years.
- Address single-brick problems as single-brick problems; they don't stay that way.

Frequently Asked Questions
Why do bricks spall in Colorado?
Brick absorbs a little water; Colorado freezes it — often forty or more freeze-thaw cycles a season along the Front Range. The expanding ice pops the outer face off the brick, and once the face is gone, the softer core erodes fast.
Can you replace bricks without it being obvious?
Yes, that's the standard we work to. We match units and mortar, and tool the joints to the original profile — the goal is a repair you have to be shown to find.
