Stop Energy Loss.
Turn Up the Comfort.
Make Your Home Perform.
If your home is hot in some rooms, freezing in others, and your energy bills feel like a personal attack on your bank account—your problem probably isn’t your AC. It’s air leakage.
At LoneStar Air Sealers, we provide professional air sealing in College Station, Bryan, Montgomery, and surrounding Texas areas, helping homeowners and builders eliminate hidden air leaks that kill comfort, waste energy, and overwork HVAC systems.
Most homes—yes, even new ones—are full of gaps and cracks in the attic and building envelope. These leaks allow hot, humid Texas air to pour in while your conditioned air escapes. The result? Higher bills, uneven temperatures, humidity problems, and a home that never quite feels right.
We fix that.
What Is Air Sealing (And Why It Actually Matters)
Air sealing is the process of closing up all the hidden gaps, cracks, and penetrations in your home that allow uncontrolled airflow.
And here’s the part most contractors won’t tell you:
Insulation does NOT stop air movement.
So if your home isn’t properly sealed, your insulation is underperforming—period.
That means:
- Your AC runs longer than it should
- Your home struggles to maintain temperature
- Humidity sneaks in and lingers
- Dust, allergens, and attic air enter your living space
Air sealing is what turns your home into a controlled environment instead of a leaky box fighting the Texas climate.
Air Sealing for New Home Construction in College Station & Bryan, TX
Building a new home? Good. Now let’s make sure it doesn’t perform like a 20-year-old one.
Most new construction homes in Texas are not properly air sealed. Why? Speed. Builders are moving fast, and detailed sealing of the building envelope is often skipped or rushed.
We come in before insulation and drywall and seal everything while it’s still accessible—when it actually matters.
What We Seal in New Construction:
- Top plates and framing transitions
- Electrical and plumbing penetrations
- Attic bypasses and open chases
- Duct connections and boots
- Wall-to-attic intersections
- Any gap that allows airflow
Why This Matters:
- Lower energy bills from day one
- Better temperature consistency throughout the home
- Reduced humidity intrusion (huge in Texas)
- Improved indoor air quality
- Less strain on your HVAC system
- Better HERS scores and code compliance
Bottom line: If you skip this now, you pay for it forever.
Attic Air Sealing & Full Attic Rehab for Existing Homes
If your home is already built, the attic is where the real issues—and the biggest wins—are.
Homes in College Station, Bryan, Montgomery, and surrounding areas are notorious for poor attic sealing. It’s one of the biggest reasons homeowners deal with high energy bills and comfort issues.
We don’t do surface-level fixes. We do full attic rehabs with professional air sealing.
Our Attic Air Sealing Process:
We locate and seal:
- Attic floor penetrations
- Recessed lights and electrical boxes
- Duct boots and HVAC connections
- Plumbing and wiring penetrations
- Top plates and framing gaps
- Attic hatches and pull-down stairs
- Open wall cavities and bypasses
In many cases, we:
- Remove or pull back existing insulation
- Properly seal all leakage points
- Reinstall or upgrade insulation for maximum performance
Because again—insulation without air sealing is wasted potential.
What You’ll Notice After:
- Lower energy bills
- Even temperatures across rooms
- Less humidity and that “sticky” feeling
- Reduced dust and allergens
- Your HVAC system finally keeping up
This is one of the highest ROI upgrades you can make to your home. Period.
Why Air Sealing Is Critical for Texas Homes
Texas heat + humidity + leaky attic = problems.
When hot, humid air enters your home through attic leaks, it doesn’t just affect comfort—it can lead to:
- Moisture buildup
- Mold and mildew growth
- Reduced insulation performance
- Long-term structural issues
Air sealing is your first line of defense. It locks down your home so your insulation and HVAC system can actually do their jobs.
Signs Your Home Needs Air Sealing
If you’re noticing any of this, your home is likely leaking air:
- Hot and cold spots throughout the house
- High energy bills (especially in summer)
- Rooms that never reach the right temperature
- Excessive dust

- Ghosting on walls
Sound familiar? Yeah… it’s time.

🔥 FAQ – Air Sealing in College Station, TX
How much does air sealing cost?
It depends on the size of your home and how much leakage is present. Most projects are far more affordable than people expect—especially considering the energy savings and comfort improvements.
Is air sealing really worth it?
Yes. It’s one of the highest ROI upgrades you can make. Lower bills, better comfort, longer HVAC life—it pays for itself.
Can I just add more insulation instead?
You can—but it won’t fix the problem. Without air sealing, insulation alone won’t stop airflow.
How long does air sealing take?
Most attic air sealing projects can be completed in a day, depending on the scope.
Do new homes need air sealing?
Absolutely. Many new homes are some of the leakiest because sealing was rushed or skipped.
