Editorial summary
Sono Spray Foam Insulation is listed at 10 Devon Ave in Norwalk, CT, with a phone number on file but no website in this record. Google lists the business as an insulation contractor, while this directory places it in crawl space work. The only verified service supplied here is crawl space repair. The listing shows a 4.9 Google rating from 33 reviews, along with an A quality grade and a 96 quality score. That gives the profile a strong local trust signal even though the fact set is narrow. Because the source data does not name additional crawl-space services, it would be inaccurate to assume encapsulation, vapor barrier installation, waterproofing, drainage, dehumidifiers, sump pumps, or foundation repair. For homeowners comparing options in Norwalk, this record supports a simple takeaway: the company has a strong review profile and a crawl-space repair focus, but further service details are not provided here.
