Stevens Insulation Services Ltd. was established in 2009 by Darren and Mary Ann Stevens. They started with a small crew servicing customers doing spray foam insulation and blown cellulose in attics.

Bob Stillman joined the Stevens Insulation team in 2016 bringing with him years of experience in the insulation and building industry and in 2019 was joined by his wife Brenda as the Office Manager.

Since that time, Stevens Insulation Services has grown to a larger sales company by focusing on servicing custom home builders and contractors across Central Ontario.

In January 2025, Bob and Brenda Stillman and their family purchased the business and have expanded their list of services to include new specialized insulation products as well a as a drywall division to better serve our customers.

In May 2026, the next generation of the Stillman family joined Stevens Insulation Services when Bob and Brenda’s daughter, Jessica, and her husband, Jesse, moved from Alberta to join the company.

Jessica brings a background in the insulation industry, experience working with the Department of Defence, and a strong passion for building science, Passive House and Net-Zero homes. Her knowledge and interest in high-performance building practices complement Stevens Insulation Services’ continued commitment to expanding its knowledge, services, and specialized insulation solutions.

Jesse brings over 20 years of experience in the drywall industry, along with a background in insulation. A retired Canadian Army veteran, Jesse served as an Infantry Soldier with the Princess Patricia’s Canadian Light Infantry. His experience in construction, combined with the discipline, teamwork, and leadership developed through his military service, adds another valuable perspective to the Stevens team.

Today, Bob, Brenda, Jessica, and Jesse are working side by side as a family, bringing together decades of experience in insulation, construction, business, and service. Together, they are building on the foundation created by Darren and Mary Ann Stevens while continuing to grow Stevens Insulation Services into the future.

Built on trust and family values, we are a customer service driven company where relationships, quality work, and efficient use of time are the three most important pillars of our success.
