As a Real Estate Agent I love having Biorganic as a company that I can trust. My client was recently quoted over $10,000 to treat mold in their attic. Peter accurately tested and assessed the situation and told us honest information that saved these homeowners thousands of dollars.

I heard about Peter with Biorganic Mold Removal from a realtor & mom in my neighborhood. We had found our chimney was leaking into our attic space and had Peter come out to assess for mold, as we felt certain that there would be mold growth found. Peter came out and actually happily told us that the wood in our attic was resilient and that what I thought was mold was actually efflorescence, but he did tell us that we had moisture problems up there and directed us with a company to fix it. He could have sold us on remediation- I was sure it was mold! But he did not. And so I wanted to make sure other people knew that this was an honest company, who wasn’t just trying to sell me on unnecessary services. Highly recommend having Peter come take a look if you suspect mold growth!
