8" Double Wall Chimney Installation Cost

Construction ITEM DESCRIPTION

Construction estimating unit cost for an 8" double wall metal chimney.

This price is for the straight chimney run-- it does not include elbows, floor sleeves, top cap or other fittings.

The labor costs are for a fairly simple run up an exterior wall, with maybe one cut through a wall or roof in a 20 foot run. Add extra labor if the project requires several floor cuts or other serious futzing. You can probably reduce the labor cost for new construction with the chimney in an interior chase.

Unit Size

One lineal foot of chimney.

Labor Costs

We figure about 4 lineal feet per hour of work by a mason or carpenter, plus one unskilled hour of help for every 20 feet of chimney..

Material Costs

Double wall chimney (priced by the inch) plus a fastener allowance.

Suggested Quantity

Goldenseal suggests the calculated height from ground level to the highest roof point. It's usually a good guess for rough estimates, but you'll probably need to adjust the height based on the actual geometry of the project.

Source of Construction Pricing

Based on crew timing from a couple of fireplace installation projects.

Places Included

Architect Starter File, Construction Starter File, Developer Starter File
