Air Sealing

Spectergy is a certified Net‑Zero Builder and Net‑Zero Renovator, specializing in airtight, high‑performance homes.

We help homeowners stop drafts, cut energy bills, and get more from their heat pumps, furnaces, and insulation by fixing one of the biggest cold‑climate issues: air leakage.

Many competitors focus on new construction, where they need open wood-framed walls before drywall goes up. Spectergy is purpose-built for existing homes, using blower door testing, thermal imaging, and precise detailing in the attic, basement, and key interior areas to improve airtightness — all without major demolition.

Our air sealing targets the hidden gaps, cracks, and bypasses that let conditioned air escape, delivering fast, high‑impact improvements in comfort.

Because air sealing boosts the performance of every other upgrade, it fits at any stage of your project — before, during, or after insulation, HVAC, or renovation work. A tighter building envelope is often the single most cost‑effective step you can take to turn a drafty house into a comfortable, efficient home.

Our Air Sealing and Testing Expertise

Spectergy treats air sealing as core building science, not just an insulation add‑on. Our team is trained by Sustainable Buildings Canada to perform ASTM E3158‑18 airtightness testing and is certified as both a Net‑Zero Builder and Net‑Zero Renovator, so the same expertise used to design ultra‑efficient homes guides every air sealing project we do.

This experience with complex airtightness testing helps us diagnose leaks accurately, prioritize the most cost‑effective upgrades, and verify results with data.

Spectergy’s team combines formal training, advanced diagnostic tools, and deep energy audit experience to deliver proof‑based air sealing, not guesswork. Every recommendation is backed by measured data — blower door results, thermal images, and clear before‑and‑after performance — so homeowners can see exactly how our work improves comfort and efficiency.

Tested, Not Guessed

At Spectergy, air sealing is tested, not guessed. We use blower door testing and thermal imaging to diagnose where your home is leaking, complete targeted air sealing, and then re‑test so you can see the improvement in real numbers.

This simple sequence — test → seal → re‑test — means you’re not just taking our word for it; you get clear, proof‑based results that show how your home’s comfort and efficiency have improved.

Why Air Sealing Matters

A well‑insulated home can still feel uncomfortable if it leaks air like a sieve. Air sealing works alongside attic insulation, basement rim joist insulation, and high‑efficiency HVAC to create a comfortable, efficient home that actually performs as designed.

By reducing uncontrolled air leakage, you can:

Improve comfort by eliminating cold drafts and temperature swings
Help your heat pump stay out of costly backup electric resistance mode
Lower heating and cooling costs all year
Reduce moisture problems, frost in the attic, and risks of mold or condensation
Increase the effectiveness of every other energy efficiency upgrade you’ve already made

Air sealing is the foundation of true home performance — and it’s where Spectergy excels.

How Air Sealing Works

Every home is different, so we start by understanding how and where your house is leaking.

Our air sealing projects typically include:

Blower door testing to measure how leaky your home is and identify problem areas
Thermal imaging (infrared camera) to visually locate cold spots, bypasses, and hidden leaks
Targeted attic air sealing, including attic hatches, top plates, plumbing and wiring penetrations, bath fans, and chimneys
Basement and crawlspace sealing, including rim joists and sill plates where outside air commonly pours in
Sealing around windows, doors, and ductwork where it provides the best return

When combined with attic insulation upgrades, duct sealing, and heat pump optimization, air sealing becomes a key part of a whole‑home comfort and efficiency strategy.

Attic Hatches, Bypasses, and Frost Problems

One of the most common issues we see is a well‑insulated attic (often R‑50 or higher) paired with a weak, leaky attic hatch. That thin panel can act like a hole in your ceiling. Spectergy upgrades attic access points by:

Adding durable gaskets and weatherstripping for a tight air seal
Installing proper latch hardware so the hatch closes firmly
Applying rigid XPS or similar insulation so the hatch matches your attic’s R‑value

These improvements help prevent warm, moist air from reaching the cold roof deck, which can cause frost in the attic that later melts and drips onto insulation and ceilings. Air sealing combined with the right insulation and ventilation protects both your comfort and your building structure.

Integrated with Our Other Core Services

Air sealing is rarely a standalone solution. It works best as part of a coordinated plan that may include:

Home energy audits and performance assessments
Heat pump consulting and optimization
Attic insulation upgrades and top‑ups
Basement and crawlspace insulation
Duct sealing and airflow balancing
Solar and renewable energy consulting

Spectergy offers turnkey consulting and project installation services so you don’t have to juggle multiple contractors. From initial testing to final verification, we design, manage, and implement upgrades that actually move the needle on comfort, efficiency, and emissions.

Results You Can Feel — and Measure

Spectergy’s approach is grounded in building science and real‑world testing. After air sealing, we can re‑test with a blower door to quantify improvements in airtightness and verify that your home is performing better.

The result is:
