Blown-In Insulation Installation
Blown in insulation uses loose fill fiberglass or cellulose blown into attics or into closed wall cavities through access holes. It fills irregular spaces more completely than batts and allows existing walls to be insulated without full removal of the drywall.

About Blown-In Insulation
Blown in insulation solves two problems batts cannot. In an attic, it flows around framing, wiring, and the irregular geometry at the eaves, filling spaces a batt would bridge over. And in an existing wall, it can be installed through small access holes without removing the drywall.
That second application is the one homeowners ask about most. We drill access holes, blow the cavity to density, then patch and texture match the holes so they disappear. It is far less disruptive than opening a wall, with the caveat that you cannot visually verify coverage the way you can in an open cavity.

Why this matters
- Fills irregular spaces batts would bridge over
- Insulates existing walls without removing the drywall
- Consistent depth across attic areas
- Access holes patched and texture matched by the same crew

How we work
Our Process
How a blown-in insulation project runs from first contact through final walkthrough.
Step 1: Assess the Assembly
We look at cavity depth, framing spacing, the space above or behind, and what the assembly needs to achieve thermally or acoustically.
Step 2: Written Scope
Estimate stating insulation type, R value or acoustic target, coverage area, and how it coordinates with the drywall schedule.
Step 3: Protect and Prepare
Area protected and any existing material removed. Insulation work generates airborne fibre, so containment matters.
Step 4: Install to Full Contact
Material installed to fill the cavity completely without compression or gaps, because both destroy performance.
Step 5: Inspect Before Close In
We inspect coverage before board goes up, because once the wall is closed nobody will ever see it again.
