Before you hire in Farmington

Lead-safe work rules apply to most homes

The typical home in Farmington was built around 1966. Painting, window, siding and remodeling work that disturbs paint in homes built before 1978 must follow the EPA lead-safe (RRP) rule. Ask any contractor for their RRP certification before work starts.

Mid-century and newer systems

Most homes here date from 1966 or later. Original furnaces, water heaters and roofs from that era are well past their service life, so replacement planning matters more than repair.

Permits: check with the Farmington building department before work starts.
