What 31-W Insulation does
31-W Insulation (legal entity 31W Insulation Company, Inc.) is a family-owned home improvement contractor founded in 1972 in Millersville, Tennessee and headquartered in Goodlettsville, Tennessee. The company provides insulation, garage doors, gutters, closet organizers, shower doors, mirrors, blinds, bath and door hardware, shelving, and fireplaces — combining branded product resale with professional installation delivered by company-trained employees rather than subcontractors. Its core offerings span insulation types (batt, blown, cellulose, spray foam, fiberglass) sourced from manufacturers including Owens Corning and CertainTeed, garage doors supplied under exclusive distribution arrangements with Amarr (and additional partnerships with Wayne Dalton and Windsor Door), and ClosetMaid-branded custom closet systems.
The business operates a sales-led go-to-market through 48 branch locations across 12 states in the Southeast and Midwest, distributing products via a company-owned truck fleet. Revenue is generated through two channels: direct sales to residential homeowners (with complimentary in-home estimates and quote-based pricing) and contractor supply, where building materials and installation services are sold to contractors serving both residential and commercial end customers. Pricing is quote-based and not publicly disclosed; online credit card payments include a 3.5% non-refundable service fee.
Customer segments include residential homeowners (primary), contractors (primary), and commercial customers (secondary). The company is BBB-accredited with an A+ rating and holds memberships in the National Association of Home Builders and the International Door Association. The company remains privately held under family ownership with no disclosed institutional investors, parent company, or subsidiaries, and operates with no public funding rounds, acquisitions, or restructuring events on record.

31-W Insulation competitors and assessment
Company assessmentDirect peers
- Installed Building Products: Largest publicly traded U.S. installer of insulation and complementary building products (shower doors, gutters, garage doors, fireplace surrounds) for residential new construction and remodel - directly comparable service mix, customer base, and installer-led model to 31-W, only at national scale.
- TopBuild: Public company formed from the merger of Masco's Installation Services and Service Partners; the largest U.S. distributor and installer of insulation and building envelope products. Overlapping product mix (insulation, garage doors, gutters) and the same residential/commercial install-contractor business model as 31-W.
- TruTeam: Private, PE-backed national installer of insulation, weatherization, and complementary home improvement products across more than 200 locations. Closest direct competitor to 31-W in residential insulation + multi-category install, distinguished by larger geography and sponsor ownership.
- Service Partners: Specialty insulation, fireproofing, and building products distributor with an installed-services arm serving residential and commercial contractors. Overlaps with 31-W on insulation distribution, contractor supply relationships, and product breadth across multiple home envelope categories.
- Precision Door Service: Largest U.S. garage door and opener repair/installation franchise. Directly comparable to 31-W's garage door product line in same end market (residential homeowners) and same GTM (scheduled estimates + service vans).
Emerging players
- Koala Insulation: Franchise-based residential insulation installer serving metro markets across multiple states. Comparable customer profile (homeowners, attic/wall/batt/spray foam) and same service-led install model, but smaller per-territory scale than 31-W's branches.
Broad incumbents
- Overhead Door Corporation: Nation's largest garage door manufacturer with an extensive authorized dealer/installer network. Relevant as a competitor and supply counterpart to 31-W's core garage door offering and as a channel through which Amarr and similar brands reach the same customers.
- Builders FirstSource: Largest U.S. supplier of building products, manufactured components, and installation services to professional homebuilders and remodelers. Overlaps with 31-W on contractor supply (insulation, garage doors) in shared geographies, though broader in scope and primarily new-construction focused.
- Home Depot Installation Services: National retailer of home improvement products with an installer marketplace covering insulation, garage doors, gutters, blinds, and closet systems. Indirect competitor to 31-W across nearly every service category, particularly for DIY-leaning homeowners shopping by SKU.
