PRIME / Exterior Wall Insulation

Improve what is inside the walls.

Cold wall surfaces and rooms that are hard to heat may be connected to empty or poorly insulated wall cavities. Dense-pack cellulose can be an option where the wall assembly is suitable.

We insulate exterior wall cavities from inside the home, through planned access in the interior drywall. This service focuses on the walls that separate your living space from the outdoors.

01 / THE REASON

Why It Matters

Walls surround much of your living space. Filling suitable exterior wall cavities can reduce unwanted heat flow. We review the wall assembly and plan access from the interior.

02 / THE PLAN

How We Approach It

We review wall construction, existing insulation, moisture conditions, and access. Where appropriate, dense-pack cellulose is installed in exterior wall cavities through carefully planned access in the interior drywall. Patching and finish expectations are agreed before work begins.
