Exterior Wall Fire Blocking Cost

Construction Item Description

Construction estimating unit cost for installation of fireblocking in wood framed exterior walls.

Unit Size

One lineal foot of exterior wall.

Labor Costs

We figure that a carpenter can install fireblocking on about 33 lineal feet of exterior wall per hour, with a bit of help from an unskilled worker.

Material Costs

We include one lineal foot of 2x4 framing lumber per foot of wall.
