Editorial summary
Installed Building Products Portland is listed at 2738 N Hayden Island Dr in Portland, OR, with a phone number on file and no website provided. The directory record identifies it as an insulation contractor and shows vapor barrier installation as the only stated service. That makes it relevant to crawl space moisture control conversations, but the listing does not say whether the company also handles crawl space encapsulation, crawl space waterproofing, mold remediation, dehumidifier installation, drainage systems, sump pumps, or foundation repair. The visible Google rating is 3.4 from 24 reviews, which gives a modest amount of review history but not a highly strong rating. No free inspection, financing, or service-area text appears in the supplied data. For homeowners comparing local options, the useful part of this record is its specific Portland location and the fact that vapor barrier installation is explicitly listed; beyond that, the published detail is limited.
