Price

What drives the cost of radon mitigation in Cottrellville

  • Foundation type: basement, slab, crawlspace or a combination
  • Material under the slab and how easily air moves beneath it
  • Number of suction points needed
  • Pipe routing: through the house or up the exterior
  • Crawlspace membrane area
  • Electrical work for the fan circuit
  • Finished basements that limit access
  • The age of the home: the typical Cottrellville home was built around 1975, so older materials, lead-safe rules and hidden damage can add time

Before you hire in Cottrellville

Lead-safe work rules apply to most homes

The typical home in Cottrellville was built around 1975. 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.

Pre-war construction

16% of homes predate 1940. Expect plaster walls, balloon framing and possible asbestos in old pipe wrap or floor tile; test before demolition with a licensed asbestos contractor.

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