Canadian Spray Foam Systems – Built on Trust, Strengthened by Community

Founded in London, Ontario seven years ago, Canadian Spray Foam Systems was born out of a commitment to quality, integrity, and doing things right the first time. What began as a small operation quickly grew into a trusted local name thanks to our passionate team, certified expertise, and a customer-first mindset.
When the COVID-19 pandemic brought uncertainty to the construction world, we leaned on what mattered most—our incredible network of loyal contractors and supportive clients. Their trust and resilience helped us weather the storm and emerge stronger than ever. The challenges of those years weren’t easy, but they reminded us why we do what we do: to deliver reliable, energy-saving insulation solutions with care, craftsmanship, and heart.
Today, we continue to serve London and the surrounding communities with pride, offering spray foam, batt insulation, blown-in insulation, and vapour barrier installation for residential and commercial projects. Every job we take on is backed by our promise: certified workmanship, timely service, and long-lasting results. We stand firmly behind our work, and we always will.
