Chimney & Fireplace Services in Fort Collins.
Chimney and fireplace care for Fort Collins homes. The median home here was built in 1992, and the nearest weather station averages 5,918 heating degree days a year.
How old is the housing a Fort Collins chimney belongs to?
Half of Fort Collins's housing units were built in 1992 or earlier, which puts the median Fort Collins home at about 31 years old by the 2023 end of the estimates that figure comes from.
That is the newest median of the four Colorado cities with a page here; the oldest is Denver at 1974, 18 years earlier.
Housing of about 1992 is more often factory-built fireplaces and direct-vent gas appliances, where the work follows the appliance's own listing and the manufacturer's instructions rather than masonry practice.
Is a Fort Collins chimney usually on a detached house?
More often than not: 52.9% of Fort Collins housing units are single-family detached, with about 47.1% counted in some other structure type.
Taken against the 73,332 housing units the Census counts in Fort Collins, 52.9% works out at roughly 38,800 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.
Most Fort Collins chimneys serve one household and can be looked at from the ground and the roof without another owner's permission; the 47.1% outside the detached category still raises the access question.

What does a Fort Collins chimney usually vent?
67.8% of occupied Fort Collins homes heat primarily with utility gas, and 0.4% heat primarily with wood.
Those are heating shares, not a count of fireplaces, but at 67.8% a Fort Collins 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 0.4% means almost no Fort Collins 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 Fort Collins chimney work in winter?
The NOAA climate-normals station nearest Fort Collins averages 5,918 heating degree days a year.
That is the lightest heating demand of the four Colorado cities with a page here: the station nearest Colorado Springs records 6,292, about 6% more.
5,918 degree days is a heating season long enough that a flue in Fort Collins 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: 5,918 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.
