Home service pros in Troy, IL

15 companies whose own websites say they serve Troy.

Housing. Troy is in Madison County. U.S. Census Bureau estimates (American Community Survey, 2019–2023) put the median year built for its 4,591 housing units at 1992; about 34% were built before 1980 and 31% in 2000 or later (Census table B25034).

  • A large share of homes went up after 2000, so many owners are now meeting their first round of furnace, AC, water heater and roof replacements. Check your subdivision's covenants or HOA rules before exterior work.
  • 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 Troy Building & Zoning Department (618-667-8734 ext. 4). The city says permits are needed for all new construction, additions, renovations and structural changes, and it adopted 2021 building codes by ordinance in 2025. Rules change, so confirm with the office before work starts.
