Denver homes and their chimneys
16.9% of Denver's homes were built in 1939 or earlier, and half were built in 1975 or earlier. HomeGuide lists lining old and unlined brick chimneys among the most common uses of a stainless steel liner, and says clay flue tiles were traditionally used in older homes. HomeGuide's chimney repair price table puts liner replacement at $1,500 to $7,000, so in an older Denver house, ask for the liner to be checked on camera during the inspection.
Denver winters and your chimney
Denver averages 156 nights a year at or below freezing and a December to February average of 31.8°F (NOAA normals, Denver International Airport). That matters for the outside of the chimney: HomeGuide says cracks in brick and mortar usually start small at the corners but can expand quickly if water seeps in and freezes. Brick repair runs $150 to $500 for minor cracks and $1,000 to $3,500 for replacing brick from the crown to the roofline, according to HomeGuide.
Chimney fires in Colorado
Chimney fires confined to the chimney or flue made up 3.9% of residential structure fires in Colorado fire department records for 2020 to 2024, above the national 3.4%. 55% of Colorado's chimney fires happened in December, January and February, a smaller winter share than the national 57.4%.

Denver no-burn days
During the winter high pollution season, November through March, the Colorado Department of Public Health and Environment says that on an air quality Action Day, indoor burning is restricted in Denver, Boulder, Broomfield, Douglas and Jefferson counties and in parts of Adams and Arapahoe counties.
It exempts Phase II EPA-certified stoves, EPA-certified pellet stoves, Colorado-approved masonry heaters, devices above 7,000 feet, and homes where indoor burning is the primary source of heat and an exemption letter has been issued. An open wood-burning fireplace is not on that list, so check the day's status before lighting one.
Local rules and resources in Denver
Planning a new fireplace? Colorado's Regulation Number 4 says that on and after January 1, 1993, no one may install a fireplace in a dwelling in the area it covers (the parts of Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas and Jefferson counties in the AIR program area, below 7,000 feet) unless it is a gas appliance, an electric device, a certified fireplace insert, an approved pellet-burning insert or another clean-burning device the state approves. That section does not apply where a substantially equivalent provision was in effect on January 1, 1993, and the regulation's high pollution day section does not apply in a municipality that had its own high pollution day ordinance in effect on January 1, 1990. The regulation lists Denver's own rules, both in Chapter 4.24 of the city code, as ordinances the city must implement and enforce: a high pollution day ordinance enacted in October 1986 and a construction ordinance enacted in May 1990. Ask the city or your installer which rule a conversion or new fireplace has to meet.
Chimney cleaning, inspection and repair in Denver
A yearly Level 1 inspection costs $100 to $250 with a basic cleaning, according to HomeGuide, and a Level 2 inspection, which adds a video inspection, costs $250 to $600; HomeGuide recommends Level 2 when buying a home with a chimney. Common repairs such as a cap replacement or crown repair cost $200 to $850. Ask whether the sweep is CSIA certified. Details: chimney sweep cost, chimney inspection and chimney repair.
