Home Tight is Closing the Gaps on Energy Loss When it comes to making a house feel like home, comfort is everything. Warm in the winter. Cool in the summer. Quiet. Fresh. Efficient. That’s where Home Tight’s specialized air sealing services come in — not as a technical add-on for builders, but as something that truly impacts how homeowners live every day. So what exactly is air sealing? “For readers who may not be familiar, air sealing is about closing the gaps you can’t see,” explains Ken Graham, Field Manager at Home Tight. “We use Aeroseal Envelope for the home’s structure and Aeroseal Duct for the ductwork. Both use a water-based acrylic mist in a pressurized environment that actually finds the leaks and seals them from the inside.” Instead of tearing into walls looking for cracks, the system sends a fine mist through the home or ductwork. The particles travel to areas where air is escaping and seal them automatically. It’s precise, efficient, and surprisingly non-invasive. But why does that matter to homeowners? Nick Azarcon, Aerobarrier Supervisor, says the biggest difference is comfort. “When conditioned air is leaking out, or outside air is leaking in, your HVAC system has to work harder. That’s when you get uneven temperatures, drafts, and higher energy bills.” Air sealing keeps heated or cooled air where it belongs. It also reduces outside pollutants, controls moisture, and even limits sound transfer between rooms or units. In multi-residential buildings, it can help prevent odours and pests from travelling between spaces.
Moisture control is another key benefit. “With air leakage comes moisture buildup inside wall assemblies,” Ken explains. “Over time, that can lead to rot or mold. Proper air sealing protects the durability of the home.” For homeowners investing in high-performance builds, including Net Zero homes from builders like Doug Tarry Homes, airtightness is critical. But even in existing homes, duct sealing can make a noticeable difference. “What’s great about Aeroseal Duct is that it can be applied to almost any home with metal ducting,” Nick says. “It’s not invasive. You don’t have to tear down walls or move furniture. You’re out of the house for half a day, and that’s it.” And the results are measurable. Home Tight performs pre- and post-testing to show improvements in leakage and airflow. Many homeowners notice stronger airflow at vents with a more consistent operation. Nick has experienced it firsthand. “I had my own ducts sealed and shaved about $40 off my gas bill. You don’t see the seal, you just feel the difference.” In the end, air sealing isn’t just about technical targets. It’s about peace of mind. A home that’s quieter, healthier, more efficient, and built to last — that’s something every homeowner can appreciate.
