For local homeowners or sellers who want to try to reduce Radon levels by only sealing the sump pit, and retesting. There are no guarantees that Radon levels will be reduced using this method.
Note: If Radon levels were greater than 6 pCi/L on a test taken at least 10 feet from the pit, your best option is to install an active Radon mitigation system from the start.

|Replacing pedestal pump with 1/3 hp submersible, sealing standard 17" pit*||

$50 / hour plus materials
* Additional charge for sealing larger sump pits. Prices do no include re-piping of ejector pipe. Some existing sump pump ejector piping may not be suitable for attaching to a new sump pump, due to size or flexibility of pipe, or if it’s unsecured. Existing ejector piping must have a minimum inside diameter of 1-1/4″, be secured (not wobbly), and be rigid PVC or ABS pipe. If these conditions are not present, we must install new ejector piping.
