insulated basement with spray foam...problem??
My house is 80 years old.
In my effort to make our house more energy efficient, I had the basement insulated 3 years ago.
I decided to use the spray foam type of insulation and hired a local insulation company to do the work.
They sprayed all 4 walls of the basement from the ground up to the ceiling.
In terms of efficiency, I am very happy with the results - the floors on main level are warmer & our utility bills have gone down.
I have noticed that our house smells a little musty & not fresh. I especially notice the smell in the spring and fall when the AC & furnace aren't running. I also notice the smell on our carpeted stairs and on our microfiber couch (mostly hardwood floors & leather furniture otherwise).
I'm worried that the spray foam insulation has made the basement too airtight and the house cannot "breathe". Could this be the cause of the musty/stale/damp smell?
How can I fix this?
Any suggestions will be very appreciated.
Thanks & regards.
