Foam cut and scraped off the underside of the roof, bagged and taken away, and the rafters photographed once they were visible. The written record of what was found is what a lender or surveyor wants to see.
More on how the work is done, and what you get at the end of it, is on our spray foam removal page. If foam in your loft is holding up a sale or a remortgage, ring 07307 928751 or ask for a written quote.
