Home service pros in Collinsville, IL

6 companies based in Collinsville and 18 more whose own websites say they serve it.

Housing. Collinsville is in Madison (partly St. Clair) County. U.S. Census Bureau estimates (American Community Survey, 2019–2023) put the median year built for its 11,779 housing units at 1970; about 63% were built before 1980 and 13% in 2000 or later (Census table B25034).

  • With so many older homes, expect pros to find original-era plumbing, wiring and ductwork. Federal rules require contractors who disturb paint in homes built before 1978 to be EPA lead-safe certified (EPA RRP rule); ask for the certification.
  • Metro East summers are hot and humid and winters bring freeze-thaw cycles, so furnace and AC tune-ups, gutter cleaning and roof checks before each season pay off.

Permits. Inside city limits, permits are handled by the City of Collinsville Community Development Department (618-346-5200). The city adopted the 2021 ICC codes as of January 1, 2025. Its most common permit is the Limited “U” permit, used for roofing, siding and windows. Rules change, so confirm with the office before work starts.
