UNSPSC 30151803: Siding butt joints

UNSPSC 30151803 Siding butt joints (Commodity) encompasses exterior cladding repair, replacement, and installation work that state and local governments solicit for building maintenance and renovation projects. Recent solicitations show the code applied to vinyl siding replacement, Hardie Plank lap siding installation, and comprehensive exterior renovation including fascia and soffit work on public facilities. Issuing bodies span county commissions, municipal governments, and public development authorities. Work typically involves removal and reinstallation of siding materials, surface preparation, caulking, painting coordination, and coordination with related roofing or gutter replacement. Contractors solicited under this code must hold commercial general contractor licenses and maintain standard liability and workers' compensation insurance, with performance and payment bonds required on most awards.

Recent opportunities are concentrated in the Southeast and Midwest. The White County Board of Commissioners (Georgia) solicited proposals for exterior vinyl siding replacement at the White County EMS Ambulance Garage with a July 31, 2026 due date (RFP, mandatory pre-proposal meeting July 10); the City of Tybee Island (Georgia) issued ITB 2026-107 for South Annex Building Repairs including approximately 320 square feet of Hardie siding installation, due May 5, 2026, with a mandatory pre-bid meeting April 21; and the Community Development Authority of the City of Madison (Wisconsin) solicited bids on the Karabis Apartments Painting and Siding Project under RFB #15051-0-2026-AH, due July 17, 2026, subject to Davis-Bacon Act prevailing-wage requirements. A fourth record tagged to this code (Sourcewell law enforcement equipment RFP #061626, due June 16, 2026) shows no material relationship to siding work and represents a classification mismatch. Geographic spread in recent activity includes Georgia and Wisconsin; no broader regional pattern emerges from the current opportunity set.
