Question from Linda
I live in San Francisco and am putting in about 50, 3″ x 10″ x 24 feet beams to cantilever a deck under our house. Its treated with ACQ-A and I’m wondering if the pesticides will off gas into our home, through the floorboards.
They will reach under our living room floor (between a basement room and the upstairs living room about 18 feet. The deck will stick outside about six feet.
Lisa’s Answer
I can’t answer that. I assume that it would depend on the construction of your home and how airtight it is. Readers, any thoughts?
Unless you could talk to an environmental specialist in architecture to get a definitive answer, why risk it? If you install it, and then get sick, it’s too late by then. Look up Mary Cordaro. She’s in Ca., and I believe does paid consultations over the phone. Debra knows her and recommended her to me at one time.
