Our Premium 4-Step Attic Insulation Process

Most contractors stop at blowing in insulation. We start with the details that actually make the difference.

Comprehensive Air Sealing

We apply high-grade foam sealant to close gaps and cracks between your living space and the attic — stopping air leakage at its source before anything else.

Soffit Vent Cleaning

Clear, functioning soffit vents allow your home to “breathe” properly — preventing moisture buildup, mold risk, and ice dams in winter.

Baffle Installation

Baffles protect your roof by maintaining continuous airflow from the soffits to the ridge vent — a step many contractors skip entirely.

Premium R-60 Blown-In Fiberglass

Only after sealing and venting are verified do we blow in industry-leading fiberglass to achieve R-60 — the gold standard for energy efficiency in this climate.

Why Homeowners Choose Peak Performance

We’re not generalists. Insulation is all we do — and we do it right the first time.
