Strong odor after crawlspace encapsulation
We had our basement encapsulated in the fall last year and made it through winter no issues. They used a thick mil high quality (apparently) vapor barrier and then sprayed /fogged with mold preventative. I don't think there is any more mold - smell is not musty really and I don't get a mold allergy reaction.
We live in a 50 year old brick ranch in Atlanta GA. Now since Spring we are smelling this bad smell. It is making me sick I believe. It smells a bit like cat urine type smell..... I have tried air cleaner, odor remover etc. with no luck. Basement is dry and at 40 percent humidity so dry. I have a dehu running as needed down there. Our furnace/AC and gas water heater are all in the crawl space as well. So we have those venting out I am hoping the smell eventually dissipates but so far it is strong and we smell it in the living space when the AC runs. A subtle yet bad smell. What to do??? I spent a lot on the encap. Didn't anticipate this bad chemical-cat urine-odd smell.
I am worried it is toxic. I don't know how to proceed. Recently had ducts professionally cleaned. Have had 2 HVAC guys checking duct connections and AC. Everything normal they say. Except the strong smell. I am pretty disparate for a solution. The crawlspace guy who did the encap said he never had any complaints about a smell....except early on he got one and he changed the material used afterwards.
