Chimney liner repair in Aurora, CO

A liner proposal should identify the existing system, show the defect, and explain why the proposed repair or replacement fits the connected appliance. Avoid choosing a liner from price or diameter alone.
Aurora homes and their flues
Public figures for Aurora as a whole. They describe local housing and heating, not your home, so the visit still starts with your own chimney.
- Median year built
- 1985
- Half of Aurora's housing units were built in 1985 or earlier, so the median Aurora chimney had about 38 years behind it by the 2023 end of the estimates. Fort Collins, also in Colorado, records 1992, 7 years newer. A liner fitted around 1985 was sized for the appliance of 1985; what matters now is whether it suits the one connected today.

- Homes heated mainly with utility gas
- 62.6%
- 62.6% of occupied Aurora homes heat primarily with utility gas, so about 37.4% run on oil, electricity, propane or something else. Wood is the primary heat in 0.1% of them. A liner has to suit the appliance it vents, and in Aurora that is a gas appliance about 62.6% of the time.

- Homes heated mainly with wood
- 0.1%
- 0.1% of occupied Aurora homes heat primarily with wood, against 62.6% on utility gas — a gap of 62.5 percentage points. Fort Collins, also in Colorado, records 0.4%, 0.3 percentage points higher. At 0.1%, almost no Aurora home depends on wood for heat, so most fires here are occasional — which still leaves deposits, and leaves the flue idle long enough for debris and nests to collect.

- Heating degree days a year
- 5,934
- The NOAA climate-normals station nearest Aurora averages 5,934 heating degree days a year. Colorado Springs, also in Colorado, records 6,292, about 6% more. Degree days measure heating demand, not freeze-thaw cycles, so 5,934 says roughly how long an Aurora flue is in use across a year, not how much the masonry around it moves. Book before the season rather than during it.

Chimney liner repair in ColoradoQuestions about liners
General answers. The findings at your home come first.
Should I stop using the appliance on that flue?
If a report or the findings say the liner is damaged, keep the appliance on that flue off until it is repaired: a damaged liner can let heat or combustion gases reach parts of the house they should not. If a carbon monoxide alarm sounds, leave and call 911.Source: U.S. Consumer Product Safety Commission, Carbon Monoxide Fact Sheet
