Review 1
This is the second house/crawl space we’ve done with this business. We came back the second time because they did a great job the first time. And the install crew did another great job again! Certainly recommend them for their work and dedication for getting the job done. Crawl space looks great…and we’ve got follow-up rodent control over the next year.

Review 2
NW Crawlspace – This is how a business should operate. NW Crawlspace completely refurbished our 2100 sq ft crawl space. The 6-man crew showed up on time and worked until well after dark, finishing the job in 2 days vice the 3 days estimated. They completely replaced the vapor barrier and under floor insulation, sealed all vents, installed rigid insulation against the foundation, sealed all potential rodent entry holes, installed a dehumidifier, and provided a thorough report with before-and-after pix. They also are coming back every 3 months for a year to ensure their rodent prevention fixes are working. I would definitely recommend NW Crawlspace to anyone needing crawl space modification.
