Chimney Cap Installation in Colorado
Professional chimney cap installation across Denver, Fort Collins, and Colorado Springs. Family-owned since 1998 · Licensed & insured · Open 24/7.
About This Service
An uncapped flue is an open hole in your roof — collecting rain and snowmelt, inviting birds and raccoons, and letting Front Range winds drive debris straight down into your fireplace. A quality chimney cap closes that hole while keeping the flue drafting freely.
We install stainless steel and copper caps sized to your flue, with spark-arrestor mesh that matters in Colorado's fire-aware communities and mounting hardware chosen for our wind. The cheap galvanized caps big-box stores sell rust and blow off; the ones we install are typically lifetime-warrantied.
Signs You Need Chimney Cap Installation
- No cap at all — you can see open flue tile from the street
- Water sounds or dampness in the firebox after storms
- Birds, nesting material, or animal noises in the flue
- Debris and leaves collecting on the smoke shelf
How Installation Day Goes
Flue and crown measured and checked — a cap on a damaged crown is a bandage, and we'll tell you.
The correct-size unit is fitted and mechanically anchored (never friction-fit) for Colorado wind.
Mesh, clearances, and draft are verified with the appliance where applicable.
Old hardware is hauled away and the roof is left exactly as we found it.
Why It Matters for Safety
An open flue admits rain, animals, and debris — and lets embers exit. In Colorado's fire-conscious communities, spark-arresting mesh on wood-burning flues protects your roof and your neighbors', which is why we treat proper capping as safety equipment, not an accessory.
Maintenance Tips From Our Technicians
- Check the cap visually after major wind events — from the ground is fine.
- Wood burners: have the mesh cleaned with each sweep; it cakes faster than you'd think.
- Rust streaks below the cap mean it's talking to you — replace before it fails.
- After roof work, verify the cap was reinstalled properly; roofers move them.

Frequently Asked Questions
Do chimney caps cause draft problems?
A correctly sized cap doesn't — it actually improves draft consistency by breaking up wind gusts that cause downdrafts. Draft problems from caps come from undersized or clogged units, which is why sizing and mesh choice matter.
What cap survives Colorado wind?
Stainless steel with bolted (not friction-fit) mounting. We've replaced too many friction-fit caps found in yards after a Chinook event to install them ourselves.
