Housing stock and what it means for service needs

•Homes built from the 1970s through the 1990s are common throughout St. Peters. Many have original furnaces, standard-efficiency air conditioners, and galvanized or polybutylene plumbing that may need updating.
•Newer subdivisions and townhome communities feature modern HVAC systems, PEX plumbing, and poured-wall foundations with drainage systems.
•Ranch and split-level homes on slab or crawl-space foundations are prevalent, making ductwork modifications and foundation access important considerations.

Common HVAC, plumbing, and foundation issues in St. Peters

•Aging furnaces and air conditioners in 30- to 50-year-old homes often need replacement rather than repeated repairs.
•Hard water throughout the area shortens the life of water heaters, dishwashers, and plumbing fixtures.
•Clay soil movement causes foundation cracks, sticking windows, and uneven floors in both older and newer subdivisions.

What to look for when hiring a contractor

•HVAC contractors should inspect ductwork and airflow before recommending a replacement system.
•Plumbers should test water pressure and hardness before installing new fixtures or water heaters.
•Foundation contractors should provide clear documentation distinguishing structural movement from normal settling.

Permit and code considerations

St. Peters follows St. Charles County building codes. Permits are generally required for HVAC replacements, water heater installations, plumbing modifications, and structural foundation work. Professional contractors should handle permits and inspections for you.

Seasonal maintenance tips

•Spring: Schedule an AC tune-up and change filters before the cooling season peaks.
•Summer: Monitor water heater temperature and pressure relief valves during high-use periods.
•Fall: Have the furnace inspected and test the ignitor and heat exchanger before heating season.
•Winter: Protect outdoor hose bibs and irrigation backflow preventers from freezing.
