Our Blown-In Insulation Process

Space Assessment and Material Selection

We evaluate the area to be insulated- attic, wall cavity, or another space- and determine the right blown-in material and density needed to reach your target coverage and R-value.

Preparation and Safety Measures

We protect surrounding areas of your home and set up equipment to ensure clean, controlled application, minimizing dust and mess throughout the process.

Blowing and Distribution

Using professional blower equipment, we distribute the insulation evenly throughout the space, filling gaps, corners, and hard-to-reach areas that other insulation types can struggle to cover completely.

Coverage Check and Final Walkthrough

We check depth and coverage across the treated area to confirm it meets the target R-value, then walk you through the completed project.

Loose-Fill vs. Dense-Pack Blown-In Insulation

Blown-in insulation can be installed at different densities depending on the application. Loose-fill is typically used in open attic spaces, applied at a lighter density for straightforward, cost-effective coverage. Dense-pack is used in enclosed wall cavities, packed at a higher density to minimize settling over time and improve air-sealing performance in spaces that can't be easily inspected or topped up later.

Benefits of Blown-In Insulation

Budget-Friendly Coverage — Blown-in insulation offers strong performance at a lower cost than spray foam.
Fast Installation — Because it's blown into place rather than applied in layers or cut to fit, most blown-in projects are completed quickly with minimal disruption to your home.
Great for Hard-to-Reach Spaces — Blown-in insulation fills irregular spaces, tight cavities, and areas around obstructions more easily than rigid materials.
Improved Comfort and Efficiency — Like other insulation upgrades, blown-in insulation reduces the strain on your HVAC system and helps even out temperatures throughout your home.

What Affects the Cost of Blown-In Insulation?

Square footage and area treated — larger spaces require more material.
Loose-fill vs. dense-pack — dense-pack applications require more material and labor.
Existing insulation condition — whether old material needs to be removed first.
Accessibility — attics or wall cavities that are harder to reach can increase labor time.

Frequently Asked Questions

Is blown-in insulation as effective as spray foam?

Blown-in insulation performs well and is a great value option, though spray foam generally offers a higher R-value per inch and better air sealing. Many homeowners choose blown-in as a budget-conscious upgrade and consider spray foam for specific high-priority areas.

How messy is the blown-in installation process?

We take care to minimize mess by protecting surrounding areas and using controlled equipment, so the process is clean and straightforward.

Can blown-in insulation be added on top of existing insulation?

In many cases, yes, as long as the existing material is in good condition and free of moisture or pest damage.

How long does blown-in insulation last?

Blown-in insulation typically lasts 20-30 years when properly installed, though loose-fill can settle somewhat over time, gradually reducing its effective R-value, which is why we factor expected settling into our initial coverage calculations. Dense-pack applications are more resistant to settling and tend to hold their performance longer.

Is blown-in insulation good for walls, or just attics?

Both. Blown-in insulation works well in open attic spaces and, when used with the dense-pack method, in enclosed wall cavities too.
