The right chimney repair starts with the cause of damage. Ask for an itemized scope that separates water entry, masonry defects, liner concerns, and any structural work.
Denver homes: age and weather
Public figures for Denver as a whole. They describe local housing and heating, not your home, so the visit still starts with your own chimney.
- Median year built
- 1974
- Half of Denver's housing units were built in 1974 or earlier, so the median Denver chimney had about 49 years behind it by the 2023 end of the estimates. Fort Collins, also in Colorado, records 1992, 18 years newer. Brick and mortar of about 1974 need repair materials matched to the existing masonry, not simply the hardest product on the shelf.

- Heating degree days a year
- 6,068
- The NOAA climate-normals station nearest Denver averages 6,068 heating degree days a year. Colorado Springs, also in Colorado, records 6,292, about 4% more. Degree days measure heating demand, not freeze-thaw cycles, so 6,068 says roughly how long a Denver flue is in use across a year, not how much the masonry around it moves. Book before the season rather than during it.

- Single-family detached homes
- 41.2%
- 41.2% of Denver housing units are single-family detached, leaving about 58.8% in some other structure type the same table counts. Colorado Springs, also in Colorado, records 60.8%, 19.6 percentage points higher. With 58.8% outside the detached category, one flue can serve more than one home and the roof may not be yours alone, so settle who approves access before the visit is booked.

- Owner-occupied homes
- 49.1%
- 49.1% of occupied Denver homes are owner-occupied, leaving about 50.9% rented. Aurora, also in Colorado, records 63.3% owner-occupied, 14.2 percentage points higher. With 50.9% rented, the person who notices the fault is more often not the person who authorizes the repair, so say which you are and the findings can be written for both.

Chimney repair in ColoradoQuestions about masonry repair
General answers. The findings at your home come first.
Why is the brick flaking?
Flaking or spalling brick usually means water is getting into the masonry and freezing, sometimes made worse by hard mortar or a coating that traps moisture. Find the water source and use compatible materials; sealing over the damage can make it worse.Source: National Park Service, Common Problems with Brick Masonry
