UNSPSC 30151800: Siding and exterior wall materials

UNSPSC 30151800 Siding and exterior wall materials is a Class code covering roof replacement, exterior cladding installation and repair, painting, gutter replacement, and related envelope work on public buildings. State and local governments procure under this code primarily through town and county facilities management departments, community development authorities, and special-purpose districts managing municipal properties. Recent solicitations show work spanning roof decking evaluation and replacement with asphalt shingles, vinyl siding repair and replacement with fiber-cement products such as Hardie Plank, fascia and soffit replacement, gutter and downspout installation, exterior painting with primer and finish coats, window replacement, and hazardous-materials disposal for older cladding. Contractors typically must carry general liability and workers' compensation insurance, provide performance and payment bonds when contract value warrants, and comply with prevailing-wage and Davis-Bacon Act requirements on federally funded projects.

Recent activity spans Connecticut, Georgia, and Wisconsin. The Town of Groton, Connecticut issued ITB 2708 for Spicer Rowing Barn roof replacement and painting due August 20, 2026, encompassing approximately 1,450 square feet of roof work with new shingles, gutters, window replacement, ridge vent installation, and exterior painting; sealed bids were due at 2:00 p.m. with no estimated contract value disclosed. White County Board of Commissioners in Cleveland, Georgia requested proposals for EMS Ambulance Garage repairs due July 31, 2026, including termite-damaged stud-wall replacement, exterior vinyl siding replacement with Hardie Plank Lap Siding, truss repairs, and painting, with a mandatory pre-proposal meeting on July 10 and general contractor licensure required. The Community Development Authority of the City of Madison, Wisconsin bid the Karabis Apartments Painting and Siding Project (RFB 15051-0-2026-AH) due July 17, 2026, covering exterior surface prep, gutter and downspout installation, soffit and fascia replacement, painting, caulking, and disposal under Davis-Bacon Act compliance. One opportunity, Sourcewell RFP 061626 for law enforcement equipment, appears unrelated to exterior building materials and signals potential code misclassification in the state and local taxonomy.
