What is sealing?
A. Sealing is any or all of the following activities: caulking the foundation wall joint, cracks and openings between the house and soil, covering and caulking the sump pit, and covering the crawlspace with membrane and adhering it to the walls and pillars therein. Q. Why was I charged more when the mitigation system didn’t reduce radon to less than 4.0? I have a warranty. A. Be sure that you understand the extent to which the warranty applies in your case before you sign the contract. A few mitigation contractors attach exemptions and/or limitations to their warranty that may render it ineffective. Know what you’re purchasing BEFORE you sign the contract and don’t authorize the work until a contract is signed. Q. The mitigator left continuous radon monitors in my house. Now I’m being charged for them.
