Insulation

Government rebate programs for home energy efficiency upgrades can significantly reduce the cost of insulation, air sealing, windows, and mechanical equipment upgrades. In many regions, the two primary programs as of 2026 are a national energy-efficiency rebate program (federal) and…

R-value is the measure of thermal resistance — how well insulation resists the flow of heat. Higher R-value means better insulation performance. In many regions’s cold climate, R-value recommendations are significantly higher than in warmer Canadian regions, and many older…

Insulation costs vary by insulation type, application, and scope of work. Here’s a practical overview of what to expect in many regions in 2026 — before rebates. “The cost question in insulation that matters most is net cost after rebates….

Insulation work is almost entirely invisible once complete — which makes it a trade where shortcuts are both easy to take and difficult to detect. A contractor who installs blown-in insulation without air sealing, blocks soffit vents without baffles, or…

A quick rule of thumb: the homeowners who avoid problems are the ones who get everything in writing, verify licensing and insurance before work starts, and never rely on a verbal promise for anything that matters. If a detail is…

Insulation is the most invisible upgrade in a home — and one of the most consequential. Done correctly, it reduces heating and cooling costs for decades, improves comfort, and qualifies for significant government rebates. Done incorrectly, it can trap moisture…

Attic insulation is the highest-return insulation investment in most local homes. Heat rises, and in an under-insulated attic, it escapes directly through the ceiling into the unconditioned attic space. Adding insulation here costs less per square foot than wall or…

Air sealing is the part of home insulation work that most contractors underprovide and most homeowners underestimate. A well-insulated home that isn’t air-sealed is like a well-insulated sleeping bag with all the zippers open — the insulation slows conductive heat…

Spray polyurethane foam (SPF) is the highest-performance insulation product available for residential use — and the one with the most significant consequences when it’s applied incorrectly. Off-ratio spray foam (incorrect mix of the two chemical components) can remain permanently tacky,…
