Even newer homes can leak air through cracks you can’t see — and those leaks quietly rob your comfort every single day. Hidden gaps in your attic, walls, or basement can let warm air escape in winter and sneak right back in during summer.

You don’t always need to see a gap to know your home is leaking air — the signs are often hiding in plain sight.
🌬️ Drafty rooms or uneven temperatures — certain spots feel colder or warmer than the rest.
🧹 Dusty or discolored insulation — air moving through insulation leaves behind dust trails.
🧊 Cold floors or walls — a sure sign that air is escaping through unsealed framing.
💧 Moisture or musty smells — humid outdoor air sneaks in and condenses where it shouldn’t.
⚙️ Rising energy use — your HVAC system runs harder just to keep up with those leaks.
To find the leaks you can’t see, Comfort 1st Insulation uses blower door testing and thermal imaging. These advanced diagnostic tools uncover hidden air pathways behind walls, around windows, and in attic spaces — giving you a clear picture of where your home is losing comfort.
🌀 Blower Door Testing — Gently depressurizes your home to reveal where outside air is sneaking in. Great for spotting leaks around doors, windows, and framing seams.
🌡️ Thermal Imaging — Uses infrared technology to show temperature differences in walls, ceilings, and floors, highlighting hidden gaps and weak insulation areas.
✅ Precision Results — Together, these tools pinpoint problem areas so our team can seal and insulate exactly where it’s needed most — no guessing, just proven comfort improvements.
Once those hidden leaks are found, Comfort 1st Insulation seals them tight with professional-grade materials designed to last. From spray foam to air sealing and weatherization, every solution is tailored to your home’s unique needs. The result? Fewer drafts, lower energy costs, and rooms that stay the same temperature all day long — no more freezing bedrooms or stuffy upstairs spaces. You’ll notice the difference not just in your comfort, but in how little your furnace or AC has to work to keep it that way.
Air sealing and proper insulation work hand in hand to create a comfortable, energy-smart home that performs better year-round. When your home is airtight and well-insulated, you keep conditioned air where it belongs — inside. That means less wear on your HVAC system, improved indoor air quality, and a quieter, more peaceful home environment. Comfort 1st Insulation takes the guesswork out of energy efficiency so you can enjoy a cozier home that saves you money season after season.
