Most problems cannot be seen with the naked eye.
Warm air, energy leaks, hidden moisture, and rodent entry points are usually invisible.
That is why we don’t start with insulation.
We start with diagnostics.
Only the combined use of a thermal imager and a Blower Door Test allows for the visualization and detection of hidden problems:

Hot? 🥵
Yeah, we noticed too. Let’s seal that attic and chill things down — for good.

Thermal images obtained with the Blower Door test are the main evidence of the quality of the work performed.
Licensed. Trained. Equipped to Test.
We do not limit ourselves to just installing thermal insulation.
Our approach begins with assessing the house as a single system:
we identify air leaks, check the ventilation system, and analyze actual heat loss using professional equipment. This enables us to select a solution that genuinely improves the building's energy efficiency.

Thermal Imaging Diagnostics
Infrared scanning helps locate hidden attic air leaks, cold spots, and insulation gaps.
What Is Included in Every Attic Project
Our standard attic package is built around measurement, correction, insulation, and verification. The goal is not just more R-value.
The goal is a tighter, better-performing attic with documented results.
The goal is a tighter, better-performing attic with documented results.
-
Blower Door & Thermal Test
Pre-work diagnostic testing measures air leakage and helps identify hidden leak points. -
Old Insulation Removal
Settled, damaged or contaminated insulation is removed before starting new work; this is a mandatory requirement. -
Air Sealing
Gaps and penetrations are sealed with appropriate sealants and fire-rated materials around key leakage points. -
Recessed Light Covers
IC-rated covers help separate fixtures from insulation and reduce leakage paths. -
Soffit Baffles
Baffles protect soffit-to-ridge airflow, which is important for Pacific Northwest moisture control. -
Ductwork Corrections
Damaged or disconnected attic ducting can be replaced or corrected so conditioned air reaches the room, not the attic. -
Blown-In Insulation
New attic insulation is installed after sealing work, targeting proper performance for the home. -
Post-Work Verification
A follow-up blower door test documents the improvement instead of asking you to trust a guess.

No more free estimates!
We calculated that a single one of our service vehicles used solely for driving to free estimate appointments consumes about 1,200 gallons of fuel a year. This results in unnecessary CO₂ emissions, which we believe is terrible for the environment.
That is precisely why we have stopped offering free estimates that provide no real value.
Now, every visit we make has a clear purpose and delivers real benefits.
$350 gets you a professional inspection, including:

What needs to be done to achieve the best result — step by step
Stage 1. Comprehensive diagnostics and measurements
-Without a Blower Door Test and thermal imaging, you're flying blind
We perform checks three times; this allows you to see the results at every stage of the isolation process.
Identify and document all problem areas.
We measure:
air leakage levels;
heat loss;
problem areas;
potential moisture accumulation sites.

air leakage levels;

potential moisture accumulation sites.
Objective:
Before blowing in the insulation.
To verify the quality of the sealing.
If the test reveals leaks, we seal them before blowing in the glass wool.

Step 2. Removal insulation
Why should old insulation be removed?
Additional benefits of insulation removal
We can detect:
Removing old insulation allows for the elimination of contaminated material and the discovery of all entry points.
- mice
- rats
- birds
- their entry points
Removing old insulation allows for the elimination of contaminated material and the discovery of all entry points.
Once cleared, the following become visible:
- roofing issues
- damaged ventilation ducts
- electrical wiring errors
- plumbing leaks
- hidden structural defects.
If there is mold in the attic, the insulation must be removed.
Even modern sprayers cannot treat surfaces hidden beneath the insulation.
The primary cause of mold is moisture.
If air leaks through the ceiling are not eliminated, humid air will continue to enter the attic, and the problem will return.

Step 3. Sealing the attic
This is the most important stage of the entire project.
It is airtightness that creates the foundation for energy efficiency.
Not the insulation.
Not the thickness of the glass wool.
But specifically the airtightness.
Not the insulation.
Not the thickness of the glass wool.
But specifically the airtightness.
- cable penetrations
- plumbing openings
- drywall joints
- ventilation openings
- utility openings
- gaps around light fixtures
- complex structural junctions.
Heat always tends to move from a warmer environment to a cooler one.
In winter:
heat tends to escape from the house.
In summer:
heat tends to enter the house.
-If the ceiling is not airtight, energy is constantly lost, regardless of the amount of insulation above it.

-If the ceiling is not airtight, energy is constantly lost, regardless of the amount of insulation above it.
Special protective enclosures and solutions that meet fire safety requirements are used for light fixtures and other components.
A second Blower Door test is conducted after the sealing work is completed.
It shows:
- whether any leaks remain;
- how effectively the work was performed;
- whether it is possible to proceed with the insulation.

Step 4. Attic ventilation
Proper attic ventilation
Many homeowners think only about insulation.
But an attic needs to do more than just retain heat.
It must be properly ventilated.
But an attic needs to do more than just retain heat.
It must be properly ventilated.
- mold;
- condensation;
- roof damage;
- attic overheating in summer;
- reduced roof service life.
- presence of soffits;
- condition of ventilation ducts;
- adequacy of air intake;
- operation of the exhaust ventilation system;
- presence of obstructions to airflow.
- installing new plastic baffles;
- creating ventilation channels;
- restoring soffits;
- installing reinforced metal mesh to keep out rodents and birds.
Stage 5. Installation of insulation
new insulation
Once the attic has been cleaned, sealed, and properly ventilated, new insulation is installed.
The attic contains:
Voids remain.
Blown-in glass wool fills the space evenly, creating a continuous thermal insulation layer.
- pipes;
- cables;
- beams;
- ventilation ducts;
- a complex rafter system.
Voids remain.
Blown-in glass wool fills the space evenly, creating a continuous thermal insulation layer.
A third diagnostic test is performed after the work is completed.
You receive:
✔ a final Blower Door report
✔ before-and-after thermal imaging photos
✔ before-and-after digital readings
✔ confirmation of the quality of the work performed

Most contractors sell insulation.
We sell verifiable results.
Most companies:
❌ do not perform blower door tests
❌ do not use thermal imaging cameras
❌ do not measure air leakage
❌ do not provide numerical results
❌ simply add new insulation on top of the old
Our approach:
✔ Diagnostics
✔ Measurements
✔ Documentation
✔ Air sealing
✔ Quality control
✔ Verification of results via photos and data
Because you cannot improve what you do not measure. And you cannot prove the quality of the work without objective testing before, during, and after the project.
