About This Service
When freeze-thaw damage, age, or past neglect push a chimney beyond spot repair, rebuilding restores it properly — from a partial rebuild of the top few courses to a complete teardown and reconstruction from the roofline up. Done right, a rebuilt chimney is better than the original, because it's built for Colorado from day one.
We rebuild with severe-weather-rated brick, correctly proportioned crowns with drip edges, and modern flue components — then finish with cap and water repellent so the new stack is protected from its first winter. Before-and-after, the difference speaks for itself.
Signs You Need Chimney Rebuilding
- The chimney visibly leans or has stair-step cracking
- Multiple courses of loose or missing brick at the top
- The crown is broken through to the flue tiles
- An inspection found structural movement or core failure
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
Do you always have to rebuild the whole chimney?
Rarely. Damage concentrates at the top where exposure is worst, so a partial rebuild of the upper section solves most cases. We rebuild only as far down as the damage actually goes.
How long does a chimney rebuild take?
A typical partial rebuild runs one to three days depending on height, access, and weather. Full rebuilds from the roofline take longer, and we schedule around Colorado's freeze windows so mortar cures properly.
What areas do you serve?
We work throughout the Colorado Front Range — roughly 65 miles around each of our three bases in Denver, Fort Collins, and Colorado Springs, from the Wyoming line down to Pueblo and up into the mountain communities.
