How Much Does a Chimney Cap Cost Installed?
A chimney cap costs $300 to $700 installed in Dallas–Fort Worth (Lowes Chimney Sweep, 2026) and $200 to $850 nationally, with custom multi-flue caps at $1,400 to $2,500 (HomeGuide, Brown Chimney). Ember Chimney & Fireplace gives a free written estimate for any cap or chase cover, with a crown check and photos, before the cap is ordered.
Here is what is in the price, what makes a cap cost more, and why a missing cap is the most expensive cheap part on the house.

What Makes a Chimney Cap Cost More
- Number of flues. One flue, one standard cap. Two or three flues close together need a custom multi-flue cap that covers the whole crown.
- Material. Stainless is the standard. Copper doubles the price for looks. Galvanized is cheaper and rusts out in a few years.
- Size and shape. Oversize, round or oval flues need a non-stock cap.
- Roof height and pitch. A steep two-story roof takes more time and gear than a single-story ranch.
- What the crown looks like. A cap mounts to the flue tile or the crown. A cracked crown gets photographed and quoted separately; see our post on why a cracked crown is an emergency.
Why a Missing Cap Costs More Than a Cap
- Rain down the flue rusts the damper ($200 to $600 to replace nationally) and the firebox floor.
- Water on the smoke shelf mixes with creosote into an acid that eats mortar joints.
- Chimney swifts, squirrels and raccoons nest in open flues; removal and sanitization after animals costs more than a cap.
- A nest or debris blockage pushes carbon monoxide into the house.
- Embers from an open flue land on the roof; the cap’s screen stops them.
