Chimney & fireplace FAQ

Straight answers to the questions Colorado homeowners ask us most.

How often should I have my chimney swept?
For regular wood-burning, once a year. Heavy users may need it twice a season. Even gas fireplaces should be checked annually. Creosote buildup is the leading cause of chimney fires, so an annual sweep is the single best safety habit.
What's included in a chimney inspection?
We follow the recognized Level 1–3 standards. A standard inspection covers the crown, cap, flashing, masonry, firebox and damper, plus a video camera scan of the flue. You get a plain-English, photo-backed report.
How do I know if my chimney needs repair?
Warning signs include falling brick or mortar, white staining, water in the firebox, ceiling stains near the chimney, a smoky smell, or a smoky fireplace. When in doubt, an inspection gives you a clear answer.
Do you work on gas fireplaces too?
Yes — wood and gas, plus inserts and stoves. Gas units need service on ignition, valves, logs and venting; we handle all of it.
Are you really available 24/7?
Yes. For genuine emergencies — a blocked flue, a storm leak, an animal in the chimney — you can reach us any hour, any day at 720-943-7149.
How much do your services cost?
It depends on your chimney and what it needs. We give honest, up-front estimates for free, with no scare tactics and no surprises. Call us for a straight answer.
Do you serve my town?
We cover 100+ communities from three hubs — Denver, Fort Collins and Colorado Springs. Use the ZIP search on our homepage or browse our service areas to find yours.
Why does my chimney leak when it rains?
Most 'chimney leaks' come from failed flashing, a cracked crown, a missing cap, or porous brick. We find the true source and fix that — not just the symptom.
Is it safe to use a fireplace with cracks in the firebox?
Not really. Cracks let heat reach the structure behind the firebox. It's usually an easy repair and worth doing before you burn again.
What is creosote and why is it dangerous?
Creosote is the tar-like residue wood smoke leaves inside your flue. It's highly flammable and the number-one cause of chimney fires. Regular sweeping removes it.
Do you clean air ducts and dryer vents?
Yes. While we're keeping your chimney clear, we can clean your HVAC ducts and dryer vents too — cleaner air and safer airflow.
