  • Mortise lock retrofits on older doors
  • New boring or filling old holes

Before you hire in Trenton

Lead-safe work rules apply to most homes

The typical home in Trenton was built around 1960. 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.

Older plumbing and sewer lines

50% of homes here were built before 1960, when cast iron drains, clay sewer laterals and galvanized supply pipe were standard. A sewer camera inspection before buying or remodeling is cheap insurance.

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