If you've ever wondered why your house feels drafty, why some rooms are impossible to keep comfortable, or whether you should tackle insulation before replacing windows or upgrading your HVAC system, you're not alone.
Everybody wants a more comfortable, energy-efficient home. Fewer know where to start, or how to get the biggest bang for their effort.
That's why we've created the Air Sealing Priority Guide: The First Five Places to Air Seal in Any House.
This new 28-page illustrated guide is designed to help Canadians understand one of the most cost-effective yet overlooked opportunities to improve comfort, reduce energy costs, and protect the long-term durability of their homes: stopping uncontrolled air leakage.
Why Air Sealing?
Air sealing is often the single most impactful and cost-effective improvement you can make to an existing house. It's not very sexy. It's grubby work, it should come before insulation and mechanical upgrades, but it's so worth it.
Here's why:
When air moves through cracks, holes, gaps, and joints in the building enclosure, it doesn't just carry heat with it. It can also carry moisture into walls, attics, and floors, contributing to condensation, mold, comfort problems, and higher energy bills.
The challenge is that most houses leak in very specific places, and most homeowners have never been shown where those places are.
The result? People spend thousands of dollars on upgrades without addressing the issues that may be undermining those investments.
Our goal with this guide is simple: help people understand enough to make informed decisions.
What's Inside the Guide?
The Air Sealing Priority Guide identifies the five locations responsible for the majority of uncontrolled air leakage in Canadian homes and explains:
- Why stopping air movement often matters more than adding insulation alone
- The first five areas to investigate and improve
- What signs homeowners can look for themselves
- Which projects may be suitable for confident DIYers
- When it's time to call in a professional
- Common mistakes that can create moisture problems
- Why ventilation and air sealing need to work together
- Simple ways to determine whether fans and ventilation systems are doing their job
The guide focuses on practical, actionable information rather than technical jargon.
Built for Homeowners. Useful for Professionals.
Although we developed the guide with homeowners in mind, we've found that the need it addresses extends much further.
Builders, renovators, energy advisors, utilities, retailers, housing providers, and community organizations all face a similar challenge: explaining why the order of improvements matters.
When homeowners understand the basics of how houses work, they can ask better questions, recognize potential red flags, and have more productive conversations with the professionals they're working with.
Better-informed homeowners often lead to better project outcomes.
Printed Copies Available
