Glad I called and selected Barrier to do the insulation work on my home renovation project. I received three to four bids on this job of removing my old blown in insulation from my attic, and installing foam insulation to two exterior walls and under the roof decking in my attic space. Barrier was not the cheapest bid by far, but the most knowledgable for sure when you talk with Rick the owner.
You need to be real careful on who you choose to blow foam in your attic/structure, the cheapest contractor can end up becoming the most expensive and causing you long term headaches and problems down the road. Do your research on this, the installer can be in-experienced, which leads to other problems, they can be using cheap Chinese foam, causing sick building syndrome, etc.
These guys have you covered and protected from those very real and potential issues, using spray foam insulation. I highly recommend you end your search here, you will be glad you did.
