Langer Construction will conduct a professional short-term radon test that meets the EPA’s radon testing standards. The testing device (a continuous radon monitor) will be placed in the lowest lived in or livable level of the home or building. Radon testing takes a minimum of 48 hours. When the test is complete, we will email a copy of the report to you. The report will display the average radon level as well as graph out the hourly levels. When the short-term test results are greater than 4 pCi/L the EPA recommends that mitigation be performed.
Langer Construction, Inc. is a licensed, certified mitigation contractor and follows all EPA protocols when installing the mitigation system.
- Install the fan in the attic if at all possible — especially in cold climate areas
- If the house has drain tile inside the footings, access the drain tile either from the sump basket or by drilling a hole in the concrete near the footing
- If the house doesn’t have drain tile inside the footings, drill a 4” hole in concrete along footings or in a centralized location and create a suction pit (approximately the size of a 5 gallon pail) below the hole
- Install an electrical outlet within 6 feet of the radon fan
- Pitch the piping so rain water will drain into the ground
- Use 3” or 4” schedule 40 PVC piping
- Seal all visible cracks and intrusions in the concrete
- Use low odor glues and sealants
- Insulate the piping in the attic (prolongs fan life and prevents freezing)
- Install U-tube pressure monitor (manometer) in a visible area
- Label piping and electrical panel with radon stickers
- Install a varmit guard on top of pipe extruding from roof
- Follow EPA’s guidelines for crawl spaces
We include a follow up radon test after the mitigation system is complete. Materials and labor are guaranteed for 5 years and is transferable. We guarantee a level below 4 pCi/L and do whatever we can to obtain lowest level possible — many times below 1 pCi/L.
We believe that there is only one way to do the job, and that is the right way! We encourage you to shop around, but make sure the company you choose is licensed and certified and follows the EPA’s guidelines.
