The problems we see most in Denver-area fireplaces and chimneys, what usually causes them, and the typical 2026 price range here.
Typical 2026 prices in the Denver metro. Cleanings are priced at the free inspection. Your exact price is written down before any work starts.
Gas first
Most Denver homes burn gas.
Gas heats 61% to 77% of homes in every Denver-area city, against 46.5% nationally (Census ACS 2024). At 5,280 feet a gas fireplace also loses about 13% of its rated input, so it needs a high-altitude setup to burn right.
Masonry
From one loose brick to a new stack.
From Capitol Hill Victorians and Denver bungalows to newer homes with metal chases, chimneys fail from the top down. We repair what can be saved and rebuild what can't.
Why Denver fireplaces and chimneys fail
Hail, frost and thin air.
Three facts explain most of what we fix across the metro.
in damage from one hailstorm
The May 8, 2017 Denver storm. Hail dents caps and chase covers and cracks crowns, and the damage often goes unnoticed until water gets in. Hail damage repair
freeze-thaw days a year in Denver
About 156 nights at or below freezing, with sunny days in between. Water in brick freezes, thaws and freezes again. NOAA normals 1991–2020
no-burn day season
On air-quality Action Days, wood burning is restricted below 7,000 feet. Gas fireplaces, gas logs and EPA-certified inserts are allowed. Make your fireplace burn-day legal

No cleaning price to haggle over at the door. We look first, show you photos, and write the price down before any work.
Chimney inspection
- Crown, cap, flashing and brick from the roof

- Photos of everything we find
- A written price for anything that needs doing
Buying or selling a house
- Same top-to-bottom look before closing
- Written findings you can hand to the other side
- Colorado requires CO alarms near bedrooms when a home with a fireplace or gas appliance is sold, and an inspection catches what a buyer will ask about
No-burn days
Keep the fire, lose the fine.
On a metro no-burn day an open wood fireplace has to stay cold. The state health department's own FAQ says it may be used only if it is fitted with gas logs, an EPA Phase III insert, an approved pellet insert or an electric device. We install all of those.

FAQ
Questions
Do you charge for the inspection?
No. The inspection is free. We check the fireplace and chimney from the roof and from inside, take photos, and write down the price of anything that needs doing before any work starts. Cleanings are priced at that visit too.
Can I use my fireplace on a no-burn day?
Only if it isn't burning wood the old way. On Denver-metro air-quality Action Days, November through March, wood burning is restricted below 7,000 feet. Gas fireplaces aren't restricted, and the state health department's FAQ says an open fireplace may be used only if it's fitted with gas logs, an EPA Phase III insert, an approved pellet insert or an electric device. The forecast is posted daily at 4 p.m.
What is the fine for burning on a no-burn day in Denver?
Denver's code sets a fine of $250 minimum, up to $2,000 per violation per day, for using a wood fireplace or stove on a high-pollution day. EPA-certified Phase III stoves and inserts and approved pellet stoves are exempt.
Did hail damage my chimney?
Possibly, even if you can't see it from the ground. Hail dents and cracks metal caps and chase covers and can crack a concrete crown, and water gets in later. We check it at the free inspection and photograph the damage so you can give it to your insurance adjuster.
Does altitude affect my gas fireplace?
Yes. Gas appliances usually lose about 4% of their input for every 1,000 feet above 2,000 feet, which is roughly 13% at Denver's elevation. A gas fireplace needs to be set up for altitude to light and burn properly.
Do I need anything for my fireplace when I sell my house in Colorado?
Colorado requires a carbon monoxide alarm within 15 feet of every bedroom when a home with a fireplace or gas appliance is sold, and after permitted work like replacing a gas appliance. Many buyers also ask for a chimney inspection, and ours is free.
Can I install a new wood-burning fireplace in Denver?
Only a certified one. Anything sold or installed in Denver must be certified, a new home or addition is limited to one wood-burning device, and since May 2020 new stoves statewide must meet the EPA's 2015 Step 2 standard.
How often should a fireplace and chimney be checked?
NFPA 211, the national standard, calls for an inspection at least once a year and cleaning when needed. Gas fireplaces need the yearly check too, for the pilot, burner, glass seal and vent.
