Most Homeowners Forget This One Thing About Their Insulation—Don’t Be One of Them!

Victoria, BC, May 23, 2025 -- When it comes to home energy efficiency, most homeowners think they’ve ticked the insulation box the moment it’s installed. But according to Advance Insulation Canada, a top-rated insulation company based in Victoria and servicing the entirety of Vancouver Island, that assumption could be costing homeowners thousands over time.

The critical issue? Air leakage.

“Insulation is only half the story,” says Robert, founder of Advance Insulation Canada. “If you don’t deal with how air moves through your home—especially through attics, crawl spaces, and around fixtures—then even the best insulation won't do its job.”

The Invisible Problem That’s Everywhere

Air leaks are often hidden in plain sight—small gaps around attic hatches, recessed lighting, electrical outlets, vents, and even plumbing penetrations. On their own, these may seem trivial. But collectively, they can significantly reduce a home’s ability to retain heat in the winter and cool air in the summer.

“Imagine zipping up a winter coat but leaving it open at the bottom. That’s essentially what happens when you skip air sealing,” says Robert. “Heat escapes, drafts come in, and your HVAC system works overtime to maintain temperature.”

Studies from energy efficiency programs across Canada estimate that uncontrolled air leakage can account for 20–40% of heating and cooling energy loss in a typical home. That translates directly into higher energy bills and increased carbon emissions, making it not only a financial issue but an environmental one too.

The Case for Re-Evaluating Older Insulation

Many homes, especially those built before modern energy codes, have insulation that’s settled, shifted, or degraded over time. Even newer homes aren’t immune, particularly if corners were cut during construction or if homeowners have since added lighting or hardware that breached existing thermal barriers.

Crawl spaces, in particular, are often overlooked. They tend to harbor moisture, pests, and poorly installed or missing insulation. Add in the common lack of proper vapor barriers or air sealing, and they become one of the biggest energy liabilities in any home.

Professional Evaluation Makes a Difference

While many homeowners attempt DIY fixes, Advance Insulation Canada stresses the importance of a professional energy audit as it’s not just to assess insulation quality but to understand how air is actually moving through a building.

“Thermal imaging, blower door tests, and physical inspections can reveal issues you can’t see,” Robert explains. “We often find homes that appear well-insulated but are hemorrhaging energy due to unseen air pathways.”

Such audits can lead to tailored recommendations which may be sealing a few specific areas, upgrading attic insulation, or addressing systemic airflow issues.

A Small Fix with Big Payoffs

Fixing air leaks isn’t always expensive or invasive. In many cases, targeted sealing and minor upgrades can result in noticeable improvements in comfort, air quality, and energy use often within a single season.

And while rebates and government incentives may offset some of the cost, the real value lies in long-term savings and sustainability.

“Homeowners think about insulation as an upfront project, something you install and forget,” says Robert. “But understanding and maintaining your home's thermal envelope should be ongoing. It's not just about comfort—it's about cost, health, and environmental impact.”
