I'm renovating the entire main floor of my 1940s bungalow, which, until now, had no insulation to speak of. I demoed right back to the brick and decided that interior spray-foam insulation made the most sense. Foam It were the first insulation company to respond to query and a consultant arrived the very next day to give me a quote which I found very reasonable.
I am absolutely delighted with the final result - the installers did a very thorough job with no mess left over and no odour whatsoever.
I found Foam It be highly professional, patient (I had to reschedule installation 3 times due to scheduling conflicts with other work) and happy to answer questions. I would highly recommend them if you are considering spray-foam insulation.
