Chimney Cap Installation in Boulder Starts With the Flue Opening
A cap sits at the top of the flue, where it helps keep rain, snow, debris and animals out while allowing smoke to escape. Before installation, we check the existing cap and the flue opening so the replacement can be matched to the chimney. With 55% of Boulder homes built before 1980, according to the US Census, checking the existing condition and fit is especially useful before choosing a replacement.
We travel to your Boulder home for the in-home inspection and installation. The visit includes checking the cap and the area where it attaches, then fitting the replacement; the time depends on access and the condition of the existing setup. For broader chimney care in the city, see our chimney sweep in Boulder page or details about chimney cap installation.

Signs Your Boulder Chimney Cap May Need Replacement
The cap is missing or visibly loose
A missing or shifted cap leaves the flue opening exposed to rain, snow, debris and animals. Have the cap and attachment checked before deciding on installation.
You see rust, distortion or a bent top
Visible damage can affect how the cap sits over the flue. A discolored or distorted rain cap can also be a sign of a chimney fire, according to CSIA’s Preventing Chimney Fires guidance; arrange an inspection rather than treating it as a routine replacement.
Debris or animal activity appears at the flue
Material around the opening or signs of animals can point to an exposed or damaged cap. We check the cap and opening to identify whether installation is the needed repair.
