For our specific needs your company was the best fit. Spray foam around the can lights and fans, walls etc. Not only is our house bearable now, my allergies and migraines are better! Pretty sure it was sealing those gaps. Omg! My heater is also not shutting off. I wish I could have afforded tinhabe insulation blown into the walls because that is the only place we still feel cold coming in from. You have no idea how nice it is to wake up to a warm house after freezing!!!! Or maybe you do!
