Protect Your Home from Radon: The Comprehensive Guide to Sealing Your Sump Pump Cover

Radon is a radioactive gas that can cause serious health problems, including lung cancer. It can enter your home through cracks in the foundation or floor, and one of the most common entry points is the sump pump cover. Sealing your sump pump cover is an important step in radon mitigation and can help to protect your family’s health.

Materials You Will Need

• Radon-resistant sealant
• Caulking gun
• Duct tape
• Utility knife
• Cleaning rags

Step-by-Step Instructions

1. Clean the surface. Before you apply any sealant, it is important to clean the surface of the sump pump cover and the surrounding area. This will help to ensure that the sealant will adhere properly. Use a cleaning rag and a mild detergent to remove any dirt or debris.
2. Apply a bead of sealant around the perimeter of the sump pump cover. Use a caulking gun to apply a bead of radon-resistant sealant around the perimeter of the sump pump cover. Be sure to get a good seal between the cover and the surrounding concrete.
3. Smooth the sealant. Use a finger or a putty knife to smooth the sealant and remove any excess.
4. Apply duct tape over the sealant. Once the sealant has dried, apply a strip of duct tape over the sealant to help hold it in place.
5. Cut the duct tape. Use a utility knife to cut the duct tape to the desired length.
6. Repeat steps 2-5 for any other openings. If there are any other openings in the sump pump cover, such as for electrical wires, be sure to seal them as well.
7. Test the seal. Once you have sealed all of the openings, test the seal by pouring water over the sump pump cover. If there are any leaks, you will need to apply more sealant.

Tips

• Use a radon-resistant sealant that is specifically designed for this purpose.
• Apply the sealant in a thick bead to ensure a good seal.
• Smooth the sealant carefully to remove any excess.
• Apply duct tape over the sealant to help hold it in place.
• Test the seal before you finish the job.
