We use premium-grade materials—spray urethane foam, caulking, weatherstr, weatherstripping, and rigid foam—to seal all air leaks around windows, doors, recessed lighting, electrical outlets, plumbing and wiring penetrations, attic access hatches, Weather Stripping Door Seal Strip.
These seals cut out drafts and prevent up to 25% of heating/cooling losses, helping HVAC systems run smarter and longer .
We perform diagnostic blower door tests to quantify air infiltration rates, using smoke pens and thermal imaging to pinpoint leaks .
The result? A full audit showing how much your home leaks and exactly where we’ll seal to seal the envelope tight.
We install top-tier insulation: spray foam (both open- and closed-cell), cellulose, fiberglass batts, rigid foam, and more—depending on your needs.
Spray polyurethane foam is one of the most effective options, with R‑values between R‑3.4 and R‑6.7 per inch, blocking air, moisture, and noise.
We optimize for installation type and budget, whether for attics, walls, crawlspaces, or rim joists.
Energy Savings
By combining air sealing and insulation, you can typically save 6–20% per year on energy bills.
Comfort All Year Round
No more cold drafts in winter or hot spots in summer—our solutions stabilize indoor temperature with fewer HVAC cycles.
Indoor Air Quality & Health
Sealing gaps helps prevent pollen, dust, smoke, and insects from entering—plus it mitigates moisture and mold risks.
Noise Reduction
Dense insulation materials like cellulose and spray foam also act as effective sound barriers.
Longevity & Lower HVAC Wear
With reduced air leakage, HVAC systems operate more efficiently, extending their lifespan and reducing maintenance.
Initial Assessment & Blower Door Test – We measure your home’s air-tightness.
Strategic Air Sealing – We address gaps with the right materials for each location.
Full Insulation Installation – Customize the insulation for attic, walls, crawlspace, etc.
Final Testing & Quality Check – A follow-up blower door test ensures we hit your target goals.
Q: What’s the best insulation for my needs?
A: For tight spaces and top R-value, closed-cell spray foam is ideal. For eco-friendly or budget-conscious choices, cellulose and fiberglass work great—especially when paired with air sealing.
Q: Can I do this myself?
Some tasks like caulking and weather stripping are DIY-friendly. But for thorough blower door testing and full-system installation, professional contractors ensure proper materials, safety, and efficiency .
Q: How quickly do I recoup my investment?
Most homeowners see a full return on investment within 1–3 years, thanks to energy savings.

âś… Success Story: How We Helped a Customer Lower Their Energy BillsÂ
In the chilly January of 2025, Zolali , a homeowner in Lasalle, Ontario, found himself frustrated.
His home felt cold and drafty. The furnace never seemed to stop running, and yet, he and his wife were constantly layering up indoors. The worst part? Their energy bills were hitting over $300 a month.
“I kept asking myself — why are we paying this much to feel this uncomfortable?”
— Zolali , homeowner
That's when Zolali found Sealed Home through a recommendation from a friend who had used their energy assessment services.
🔍 Step 1: Energy Assessment & Air Leakage TestÂ
Our certified energy advisor performed a blower door test and discovered significant air leakage around:
The attic hatch
Basement Penetrations through Headers
Door and window frames
Zolali decided to move forward with air sealing only — no insulation upgrades at this stage.
Our crew:
Caulked all accessible cracks and seams
Sealed basement Penetrations through Headers with spray foam
Applied weatherstripping on exterior doors and attic access
⚠️ Important:
Zolali only completed air sealing, not insulation.
If attic or wall insulation had been added, his savings would’ve been even higher.
