Why Attic Insulation Matters

Insulating your attic helps your whole home feel more comfortable year-round. It keeps heat inside during winter and blocks hot air in summer, so your HVAC doesn’t work overtime.

It can also help improve indoor air quality by sealing out contaminants. You’ll notice steadier temperatures, fewer drafts, and potential savings on energy bills.

A Complete Attic Service, Start to Finish

We do more than just blow insulation into the attic.

 

Every job starts with a full attic cleaning to remove old insulation, debris, and any signs of pests. We then seal leaks and penetrations in the Sheetrock and roofline using foam and other materials to block air gaps. From there, we install high-quality blow-in insulation to evenly cover every corner.

 

This process improves air quality, reduces heat loss, and helps create a cleaner, more efficient home from top to bottom.

 

We’re also a Puget Sound Energy (PSE) rebate partner, which means you may qualify for insulation rebates when we handle the work. We’ll walk you through what’s needed to help make the most of available savings.

How Our Attic Insulation Process Works

Remove old insulation and debris

We start by clearing out damaged insulation, debris, and signs of pests to get a clean working space.

Inspect for damage and air leaks

Our team checks for mold, water damage, and hidden air gaps—especially around light fixtures and penetrations in the Sheetrock.

Seal and prepare the attic

We use fire-safe foam to seal leaks, install screens for airflow, set measuring rulers for proper R-value, and add soffit breathers to support ventilation.

Install new blow-in insulation

We apply high-performance insulation evenly across the attic to maximize coverage and improve energy efficiency.
