Editorial summary
Quality Insulation of Portsmouth is listed at 360 Constitution Ave in Portsmouth, NH. The directory record identifies it as a crawl space specialist, and the only service shown is crawl space encapsulation. The Google category is insulation contractor, which fits the general home-performance side of the work, but the supplied facts still stay narrow. A phone contact is listed. No website is provided. Public review data is present, though it is limited: Google shows a 3.7 rating from 15 reviews. That is enough to give a basic public signal, but not enough to suggest a particularly robust online reputation either way. The record does not include a stated service area, years in business, free inspection information, or financing information. Because the supplied facts confirm only crawl space encapsulation, it would be inaccurate to extend the service list to waterproofing, drainage, mold treatment, or other related work. For a homeowner comparing Portsmouth crawl-space providers, this entry is best read as a minimal but usable directory record with modest review support and few extra details.
