About Us

Avalon Spray Foam is owned and operated by Sam Thornhill.  My training and 25 years of experience in the construction industry has taught me that many buildings are not insulated and sealed as well as they could be.


This can lead to drafts, dust, mould, rot, noise, and high energy bills.  As a result I started Avalon Spray Foam to provide customers with a more efficient way to insulate and seal their buildings.
