Chimney Replacement in Colorado
Chimney Replacement by Donovan Chimney & Fireplace: honest diagnosis, written pricing, and quality work across the Colorado Front Range. Family-owned since 1998 · Licensed & insured · Open 24/7.
About This Service
Chimney replacement is for systems past saving — structurally failed masonry stacks, rotted prefab chases, or obsolete metal systems with unavailable parts. We remove the old system safely and build its successor correctly, whether that's new masonry, a rebuilt chase, or a modern Class-A installation.
Replacement is also an opportunity: the new system gets sized to the appliances you actually use, insulated for altitude draft, and terminated with the crown, cap, and flashing details the original probably lacked. Homeowners are routinely surprised how much better the replacement performs.
Signs You Need Chimney Replacement
- A condemned or structurally failed chimney
- Prefab chase framing rotted beyond repair
- An orphaned metal system with no available parts
- Repair estimates approaching rebuild cost
How We Work
Every project starts with assessment and photos — decisions from evidence.
Scope and pricing in writing before work begins; no surprises mid-job.
Work performed to code by trained, insured technicians.
Final walkthrough and documentation; 24/7 reachability if anything comes up.
Why It Matters for Safety
Everything we do traces back to two risks: fire and carbon monoxide. Codes, inspection standards, and our own procedures exist to keep both where they belong — and 24/7 availability means the urgent version of either always has someone to call.
Maintenance Tips From Our Technicians
- One annual service visit prevents most emergencies we see.
- Keep a simple file: inspections, sweeps, repairs — it compounds in value.
- Changes in smell, draft, or sound are the system communicating; call early.
- Our line answers 24/7 — the middle-of-the-night question is always welcome.

Frequently Asked Questions
Can you replace just the above-roof portion?
Yes — when damage is confined to the exposed section, partial replacement from the roofline up is common and sensible. Full replacement is for systems compromised through the structure.
Will replacement disrupt the house much?
Exterior masonry replacement mostly happens outside your walls. Interior chase or full-system work is more involved; we protect finishes, contain dust, and sequence the work to keep your home livable throughout.
Are you licensed and insured?
Fully. Donovan Chimney & Fireplace carries the licensing and insurance this work requires, and certificates are available on request — something we recommend asking of any company that climbs on your roof.
