Waterproofing and Building Envelope Estimating
Waterproofing, air barrier, sealant and cladding estimates for the parts of the envelope that keep water and air out.
Waterproofing and Building Envelope Estimating Overview
Envelope scopes are spread across many details: foundation walls, wall sections, window heads and sills, and joints between materials. We take off waterproofing and air barrier areas, measure sealant joints by length and size, and quantify siding and cladding systems with their trims and accessories.
Together with roofing and insulation, this page covers CSI Division 07. Separating the three keeps each estimate focused on how that work is bought and installed.
Also covered on this page: Thermal and moisture protection (CSI Division 07), other than roofing and insulation.
