Chimney & Fireplace Services in Denver.
Chimney and fireplace care for Denver homes. The median home here was built in 1974, and the nearest weather station averages 6,068 heating degree days a year.
How old is the housing a Denver chimney belongs to?
Half of Denver's housing units were built in 1974 or earlier, which puts the median Denver home at about 49 years old by the 2023 end of the estimates that figure comes from.
That is the oldest median of the four Colorado cities with a page here; the newest is Fort Collins at 1992, 18 years later.
Around 1974 masonry chimneys and factory-built fireplaces were both common, so which of the two is in the house decides the scope of the visit and which parts fit it.
Is a Denver chimney usually on a detached house?
Usually not: only 41.2% of Denver housing units are single-family detached, so about 58.8% are counted in some other structure type.
Taken against the 352,593 housing units the Census counts in Denver, 41.2% works out at roughly 145,300 detached homes; the same table files the rest under some other structure type, from an attached house to an apartment building or a mobile home.
With 58.8% outside the detached category, a Denver chimney can serve more than one home and the roof it stands on may not be yours alone, so who approves access is a question to settle before the work is booked, not on the day.

What does a Denver chimney usually vent?
61.5% of occupied Denver homes heat primarily with utility gas, and under 0.1% heat primarily with wood.
Those are heating shares, not a count of fireplaces, but at 61.5% a Denver flue is more likely to be carrying the exhaust of a furnace, boiler or water heater than the smoke of a wood fire, and that flue needs checking for blockage, moisture and liner condition rather than creosote.
A wood share of under 0.1% means almost no Denver home depends on wood for heat, so most fires here are occasional — which still leaves deposits, and still leaves the flue idle long enough for nests and debris to collect.
How hard does a Denver chimney work in winter?
The NOAA climate-normals station nearest Denver averages 6,068 heating degree days a year.
Across the four Colorado cities with a page here the stations run from 5,918 near Fort Collins to 6,292 near Colorado Springs, putting Denver about 3% above the milder end.
6,068 degree days is a heating season long enough that a flue in Denver is working steadily for a good part of the year; book the inspection before it starts rather than during it.
Degree days measure heating demand, not freeze-thaw cycles: 6,068 says how long the flue is in use, not how much the masonry around it moves.

Before we visit.
Which service should I request?
If the cause is unclear, start with an inspection and describe what you’ve noticed. Water, cracking, smoke, and an appliance that will not light can involve different parts of the system.
What should I have ready?
Have any previous inspection reports and accessible appliance information ready. Note when the concern appears. Do not climb onto the roof or operate an appliance that shows unsafe symptoms.
What if I smell gas or a carbon monoxide alarm sounds?
Leave the building and contact emergency services or your gas utility from a safe location. Do not use the estimate form for emergency assistance.
