About JCL Insulation
JCL Insulation operates as an insulation contractor serving Lynnwood, Washington and surrounding communities in the greater Seattle metro area. The business holds a 3.5-star rating derived from 8 customer reviews, reflecting a mix of homeowner experiences with residential spray foam projects. Core service offerings span attic insulation, basement waterproofing, crawl space encapsulation, insulation removal, and both residential and commercial spray foam applications.
The contractor specializes in spray foam insulation solutions, distinguishing itself through closed-cell spray foam installations that deliver higher R-values compared to conventional fiberglass batts. Website offerings include no-burn intumescent coatings for fire resistance, pole barn insulation, and basement waterproofing services. This focus on spray foam rather than traditional batting materials positions the business as a specialist in air-sealing and thermal performance for region 4 marine climate zones.
