Fireplace Repair in Colorado
Professional fireplace repair across Denver, Fort Collins, and Colorado Springs. Family-owned since 1998 · Licensed & insured · Open 24/7.
About This Service
Fireplace repair covers the living-room side of the system: cracked firebrick and mortar joints in the firebox, failing dampers, deteriorated hearths, loose facing, and the dozens of small failures that turn a fireplace from an asset into a worry. Most are inexpensive to fix — and expensive to ignore.
We repair both masonry fireplaces and factory-built units, sourcing correct refractory panels, gaskets, and parts for prefab systems and doing genuine firebrick and refractory mortar work on masonry ones. One visit, an honest assessment, and repairs matched to what the fireplace actually needs.
Signs You Need Fireplace Repair
- Cracked or crumbling joints between firebricks
- Gaps opening between the firebox and the facing
- A damper that won't open, close, or seal
- Cracked refractory panels in a factory-built unit

Why It Matters for Safety
The firebox and its surround are engineered as a containment system; every open joint or cracked panel is a breach in it. Manufacturers and NFPA 211 are unambiguous: visible firebox damage means stop burning until it's repaired.
Maintenance Tips From Our Technicians
- Vacuum ash regularly, but leave an inch — an ash bed insulates and improves burning.
- Cracks in firebox joints are stop-burning findings; check monthly during season.
- Operate the damper fully monthly even off-season to keep it free.
- Glass doors closed at night reduce heat loss and stray embers.

Frequently Asked Questions
Are small cracks in the firebox really a problem?
Hairline surface crazing is normal; open cracks and failed joints are not — they can let heat reach framing behind the firebox. The distinction takes an experienced eye, which is exactly what an assessment visit is for.
Can you get parts for my older prefab fireplace?
Usually. We work with the major manufacturers' parts channels and universal-fit refractory suppliers, and when a unit is genuinely unsupported, we'll tell you straight and walk through insert options.
How soon can you come out?
Routine appointments are usually available within the week, and our 24/7 emergency line handles the situations that can't wait. October and November book fastest — spring and summer scheduling is easiest.
