238170

Analysis

NAICS 238170 is the 2022 national industry for siding contractors, part of 23817 (Siding Contractors). Census lists 13 example activities under it in the official index.

Between 2018 and 2023 the number of establishments grew 15% and employment rose 16%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.

County Business Patterns counts 9,142 US establishments in this code in 2023, employing 41,885 people at an average annual payroll of $58,783 per employee (31st percentile of national industries). 75% of the establishments have fewer than five employees, which marks it as a small-business industry.

Its index entries, the activities Census uses to assign businesses to this code, include aluminum siding installation, downspout, gutter, and gutter guard installation, eavestrough installation and fascia and soffit installation, among 13 in all.

Census lists 3 related activities that belong elsewhere, most often in 238140, 238190 and 238220. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.

For example, installing brick, stone, or stucco building exterior finish materials are classified in 238140 (Masonry Contractors) instead.
