Use this wall sheathing cost calculator to estimate a planning range for exterior wall sheathing installation or replacement. It includes sheet count, OSB or plywood material, wall height, stories, siding removal, WRB or housewrap, flashing tape, rot risk, access, and restoration.
This is not a contractor bid. Wall sheathing costs can change after siding comes off and hidden water damage, missing housewrap, bad flashing, damaged framing, mold, or poor nailing is exposed.
Estimate your wall sheathing cost
How this estimate works
The calculator converts wall area into sheets, adds material cost, labor allowance, siding removal, WRB and flashing work, hidden damage risk, wall height, access, and regional labor adjustment.
Why wall sheathing cost changes after siding removal
Rot, missing housewrap, failed flashing, mold staining, damaged framing, bad nailing, and trapped water often stay hidden until siding and trim are removed.
