Siding contractors install exterior cladding — vinyl, wood, fiber cement, aluminum, and similar materials — on residential and light commercial structures. Work often includes related components such as gutters, downspouts, fascia, and soffit. Projects range from full new-construction exterior packages to repair or replacement on existing buildings, typically performed by small crews working from ladders and scaffolding.
Questions to investigate
- What percentage of work is residential vs. commercial or multi-family?
- Does the operation include any EIFS, stucco, or composite panel installation alongside traditional siding?
- What is the split between direct labor payroll and subcontractor costs — and does the contractor collect certificates from all subs?
- Are any roofing, window installation, or other trades performed under the same operation?
