📘 Our Story

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.

🌡️ Smarter Insulation Starts with Energy Audits

Partnering with Experts to Help You Save More with Canadian Spray Foam Systems

  • At Canadian Spray Foam Systems, we believe every home and business deserves maximum comfort and minimal energy waste. That’s why we work hand-in-hand with certified energy auditors in London, Ontario and surrounding areas to offer tailored insulation upgrades that deliver real, measurable savings.

🔍 Why Energy Audits Matter

  • An energy audit is the first step toward understanding where your building is losing heat, costing you money, and reducing comfort. These audits assess air leakage, insulation gaps, ventilation systems, and overall thermal performance.
  • Through partnerships with trusted auditors, we identify problem areas and recommend insulation solutions that make sense not just for your building, but for your budget.

🏡 Our Insulation Services

  • Based on your audit results, we install the right mix of high-performance insulation materials to optimize your building envelope:
  • Spray Foam Insulation
    Ideal for sealing air leaks and providing a continuous thermal barrier. It’s especially effective in attics, crawl spaces, rim joists, and hard-to-reach areas.
  • Blown-In Insulation
    Great for retrofits and increasing R-values in attics and wall cavities. It quickly boosts efficiency with minimal disruption.
  • Batt Insulation
    A cost-effective and reliable solution for walls, ceilings, and floors. Our precise installation ensures full coverage with minimal waste.

✅ Certified Installers with a Customer-First Approach

  • Our team consists of experienced, certified professionals who pride themselves on friendly communication, reliable scheduling, and clean job sites. We work efficiently and respectfully treating your property like it's our own.
  • Every project is completed with care and backed by a commitment to quality, so you’ll feel the difference not just in your comfort, but in your utility bills.

💰 Maximize Rebates & Savings

  • Through our collaboration with energy auditors, you may qualify for government rebates or incentives that further reduce the cost of upgrading your insulation. We’ll help guide you through the process so you get the most out of your investment.
  • Warm up in winter, cool down in summer, and save year-round with insulation that works as hard as we do.
