Vapor Barrier Installation

What This Service Involves

Moisture management is critical in our marine climate, and a correctly placed vapor barrier keeps damp ground and humid air from condensing inside assemblies. In crawlspaces, we lay and seal a durable ground barrier; in walls, we position vapor retarders to match the assembly's drying direction. Getting the placement and permeability right prevents the trapped moisture that leads to rot and mold. The result is a drier, healthier, longer-lasting structure.

Benefits

Blocks ground and air moisture migration; Protects framing from rot and mold; Improves crawlspace and indoor humidity; Supports insulation performance; Extends the life of the structure

Our Process

1) Evaluate moisture sources and assembly drying; 2) Select the correct barrier permeability; 3) Install and overlap the barrier, sealing seams; 4) Detail edges, penetrations, and transitions

What Affects the Cost

Area to be covered and barrier grade; Crawlspace ground versus wall application; Sealing, taping, and detailing labor; Existing moisture remediation; Access and site conditions

Best Time of Year

Vapor barriers can be installed any season and are especially valuable ahead of the wet Northwest winter.
