Looking for a reasonably priced insulation company?

I wonder if anyone here knows anything about spray foam insulation that is sprayed in thru small holes made in the top of the walls and under windowsills? If so, if you can recommend a good company that does this

Is there a company in Haldimand-Norfolk that does spray (foam) insulation? I cannot go through another winter with frozen feet and neither can my daughter who rents the other side of this duplex!! Thanks!
