Duct Sealing Services for Whistler & Squamish Homes
Improve energy efficiency and comfort in mountain climates with professional Aeroseal duct sealing.
Living in the breathtaking Sea-to-Sky region comes with unique home comfort challenges. From Whistler‘s sub-zero winter temperatures to Squamish‘s fluctuating humidity levels, your home’s duct system faces extreme conditions that can compromise its performance. At Airtight Solutions, we specialize in helping Whistler and Squamish homeowners overcome these challenges with advanced Aeroseal duct sealing technology – delivering more comfortable living spaces, reduced energy bills, and improved indoor air quality.

Why Homeowners in Whistler & Squamish Need Duct Sealing
The stunning mountain landscapes of Whistler and Squamish create a paradise for outdoor enthusiasts, but they also present unique challenges for your home’s comfort systems. Whistler’s long, harsh winters and heavy snowfall, combined with Squamish’s year-round humidity fluctuations, expose the vulnerabilities in unsealed duct systems.
Most homes in the Sea-to-Sky corridor lose 20-30% of heated and cooled air through leaky ducts. These leaks waste energy and create frustrating comfort problems: cold spots in bedrooms, uneven heating across floors, and stuffy air despite constantly running your system. For vacation properties that sit empty during off-seasons, these inefficiencies can lead to concerning moisture issues, potential mould growth, and unnecessarily high utility bills.
Mountain homes with crawlspaces, split-level designs, or complex roof lines are particularly vulnerable to duct leakage. The extreme temperature differentials between indoor and outdoor air in Whistler and Squamish create stronger pressure imbalances that force air through even the most minor duct gaps.
Benefits of Professional Duct Sealing in Whistler & Squamish
Investing in professional duct sealing delivers immediate and long-lasting improvements for your Sea-to-Sky region home:
Save up to 20% on Heating and Cooling Costs: Mountain living means significant heating demands during Whistler’s long winters. By sealing leaky ducts, you’ll keep that expensive heated air where it belongs – inside your living spaces. Many homeowners see a return on their investment within 2-3 heating seasons through lower energy bills.
Experience Consistent Comfort Across All Levels: Say goodbye to those frustrating temperature differences between your main floor and bedrooms. Proper duct sealing ensures conditioned air reaches all areas of your home as designed, eliminating cold spots and overheated zones common in multi-level Whistler and Squamish homes.
Breathe Cleaner, Healthier Indoor Air: Leaky return ducts pull unwanted contaminants from attics, crawlspaces, and between walls. In a region where many residents suffer from seasonal allergies, our duct sealing process creates a closed system that significantly improves indoor air quality by preventing dust, pollen, and other irritants from entering your breathing air.
Prevent Moisture Problems and Mould Growth: The humidity challenges in Squamish homes and seasonal Whistler properties make moisture control essential. Properly sealed ducts help maintain appropriate humidity levels throughout your home, reducing condensation issues that can lead to mould growth and structural problems.
How Aeroseal Duct Sealing Works in Your Mountain Home
Our non-invasive Aeroseal technology makes duct sealing simple and effective, even in hard-to-access areas common in mountain home construction. The process takes just one day and follows three straightforward steps:
Comprehensive Inspection: We begin by thoroughly evaluating your existing ductwork using specialized diagnostic equipment. This assessment identifies where leaks occur and establishes a baseline leakage rate, allowing us to quantify improvements.
Advanced Sealing Process: Next, we temporarily block your registers and inject a safe, water-based aerosol mist into the pressurized duct system. This patented Aeroseal technology works from the inside out, with microscopic particles finding and sealing leaks up to 5/8″ in size. The process effectively addresses hard-to-reach areas behind walls and in crawlspaces without demolition.
Verification and Documentation: After sealing, we conduct a final test to measure the improvement and provide a computer-generated certificate documenting the before-and-after results. Most Whistler and Squamish homes see an 85-95% reduction in duct leakage, with improvements you’ll feel immediately.
The entire process typically takes 4-8 hours, depending on your home’s size and duct configuration. There’s no mess, no wall cutting, and no disruption to your home’s structure – just measurably better comfort and efficiency.

Frequently Asked Questions About Duct Sealing in Whistler & Squamish
The Aeroseal sealant has been tested to last 40+ years. It remains flexible to accommodate the natural expansion and contraction of ductwork that occurs with mountain temperature fluctuations.
Absolutely. Vacation properties often benefit most from duct sealing, as it helps prevent energy waste during unoccupied periods and reduces moisture-related issues that can develop when homes sit empty.
Yes. By sealing your ducts, your humidification systems (if present) work more effectively, as the moisture you add to the air stays in your living space rather than escaping through leaks.
Duct sealing is often the more cost-effective first step. Even the most efficient heating system wastes energy if it pushes air through leaky ducts. Many Whistler and Squamish homeowners find their existing systems perform dramatically better after proper duct sealing.
No ongoing maintenance is needed for the sealant itself. We recommend continued regular maintenance of your HVAC system for optimal performance.
