Chimney Sweeps in Evergreen, Colorado: Wood Stoves, Wildfire Country and Altitude

Long burn seasons build creosote. Creosote is the tar-like residue that condenses when smoke cools in the flue. A stove burning daily for seven or eight months can reach the 1/8-inch depth that CSIA-trained sweeps treat as a cleaning trigger by midwinter. See our creosote guide.

Cold air pools in the drainages. On calm winter nights, cold air settles along Bear Creek and in other low spots. Smoke lingers, and a cold exterior chimney on the north side of a house can refuse to draft until the flue is warmed with a small, hot kindling fire.

Snow slides off steep roofs. Eighty inches of snow a year piles against the uphill face of chimneys, melts in afternoon sun and refreezes at night, forcing water under the flashing (the metal seal between chimney and roof). A cricket, a small peaked roof section behind the chimney, is the standard fix on wider chimneys.

Forest on every side. Pine needles pack into roof valleys behind chimneys and branches overhang flue tops, so a chimney fire or a missing spark arrestor carries far more risk than in town.

Altitude. Draft depends on the weight difference between hot flue gas and cold outside air, and that difference shrinks as air pressure drops. Large open fireplaces with short chimneys are the most likely to spill smoke, and stove manuals often call for taller chimneys at elevation. See chimney smoke and draft problems.

Evergreen was settled in 1859, got its post office in 1876, and spent decades as a summer retreat for Denver families before growing into a year-round commuter community. The result is a wide mix of chimney types on a single road.

Many Evergreen homes have two or more flues (a lower-level stove plus an upstairs fireplace, or a fireplace plus a furnace flue), and each is priced separately. The most common problem in older houses is a wood insert slid into a masonry fireplace and vented into an oversized clay flue with no stainless liner. It drafts poorly, builds creosote fast and is hard to sweep. See fireplace inserts and chimney liners.

Evergreen has no town government, so Jefferson County, the state health department and Evergreen Fire/Rescue each handle part of the picture.

Jefferson County building permits

The Jefferson County Building Safety Division (100 Jefferson County Parkway, Golden; 303-271-8260) issues permits for unincorporated areas including Evergreen. The county requires a mechanical permit for wood-burning fireplaces and stoves, submitted in person or by email, and reviews each system for EPA Phase II compliance against EPA's certified wood stove database. Gas fireplace installs also need a permit, with the gas line run by a properly licensed contractor. Ask the division whether a reline or rebuild above the roofline counts as a permitted alteration. Sweeping, inspection, caps and waterproofing normally need no permit. Permitted fuel-appliance work also triggers Colorado's CO alarm law (C.R.S. 38-45): working alarms within 15 feet of each sleeping room entrance.

Denver-metro Action Days and the 7,000-foot exemption

Jefferson County is one of the seven counties in the Denver-Boulder high-pollution program under Regulation No. 4. The Colorado Department of Public Health and Environment (CDPHE) issues a forecast daily at 4 p.m. from October 31 through March 31. On an Action Day, open wood fireplaces and uncertified stoves may not be used in the program area, but CDPHE exempts homes above 7,000 feet.

Downtown Evergreen is just above that line and most hillside homes are higher, but some lower sections along Bear Creek east of downtown sit close to it. If your home is near 7,000 feet, confirm its elevation from a topographic map or survey before relying on the exemption.

The exemption covers only the Action Day restriction. It does not override the statewide rule that new stoves must be EPA-certified, your HOA covenants or county fire restrictions. Check status on CDPHE's air quality advisory page or at 303-758-4848.

Evergreen Fire/Rescue and wildfire rules

The Evergreen Fire Protection District (Evergreen Fire/Rescue), 1802 Bergen Parkway (303-674-3145), runs eight stations and offers free defensible-space home assessments, a chipping program for slash, and burn permits and fire-pit rules for outdoor fires. Ask the assessor to note branches over your chimney and needles on the roof around it. County fire restrictions mostly target outdoor fires, but keep ashes in a lidded metal can on a noncombustible surface at all times.

Colorado's 2025 Wildfire Resiliency Code (8 CCR 1507-39) applies in mapped wildland-urban interface (WUI) areas to new homes, additions of 500 square feet or more, and replacement of 25% or more of a roof or exterior wall. It focuses on roofs, walls and vents, not chimneys, but fire officials and many insurers expect a spark-arrestor cap on every wood-burning flue in the forest.

Evergreen falls in the foothills tier of our Colorado pricing, roughly 10–25% above national averages because of canyon drive time, steep roofs, multi-flue chimneys and heavy wood use. Ranges are estimates based on 2026 national surveys (HomeGuide and Angi) adjusted for foothill labor and access.

Tall stone chimneys cost more to repoint or rebuild than brick, and a second flue pushes a sweep toward the national two-flue range of $250–$400 before the foothill premium.

Colorado has no state chimney sweep license, and Jefferson County does not license sweeps for cleaning, so vetting is up to you:

1. Search the CSIA "Find a Pro" tool and the National Chimney Sweep Guild directory; check reviews and the BBB.
2. Ask how often they work above 7,000 feet, on steep roofs and on stoves used as primary heat.
3. Verify CSIA or NFI certification numbers with the issuing body.
4. For installs, get it in writing that the installer pulls the Jefferson County permit.
5. Ask for photos or camera footage before approving a liner or rebuild, and for liability and workers' comp certificates.

Complaints go to the Colorado Attorney General's Consumer Protection Section (1-800-222-4444). See how to hire a chimney sweep and chimney sweep scams.

• Keep branches at least 10 feet from the chimney outlet and clear the roof valley behind the chimney each spring and fall.
• Stack firewood away from the house, and buy it locally; the state advises against moving firewood because of emerald ash borer. See our firewood guide.
• Have propane appliance vents checked with the annual sweep.

Sweeps working Evergreen typically also serve Bergen Park, Kittredge, Idledale, Indian Hills, Morrison, Genesee, Conifer, Aspen Park, Pine, Bailey and Idaho Springs. See the Colorado chimney guide and the city pages for Denver, Littleton and Boulder.
