Why Attic Insulation Matters in Marin County
Living in Marin means dealing with cool coastal air, warm inland summers, and older homes with less-than-ideal insulation. If your attic was insulated 15+ years ago (or never at all), chances are you’re paying more than you should on heating and cooling.
We specialize in:
Attic insulation upgrades
Complete insulation removal and cleanup
Blown-in insulation installation
Air sealing and energy efficiency consulting
As a trusted insulation contractor in Marin County, we start every job with a free attic inspection. From there, we’ll walk you through your options, explain what’s worth saving — and what needs replacing — and deliver a same-day quote.
The Power of Blown-In Insulation
While we offer different insulation materials depending on the structure and needs of the home, we often recommend blown-in insulation for attics — especially in retrofits or irregularly shaped spaces.
Blown-in insulation, made of either cellulose or fiberglass, is applied using a machine that disperses the material evenly across the attic floor. This creates a consistent thermal blanket that reaches every nook and cranny, including areas that are difficult to cover with traditional batts or panels.
As a professional blown insulation contractor, we know how to get full, even coverage without compromising ventilation or airflow. This method is fast, clean, and ideal for topping off old insulation to improve overall R-value without a full removal.
Safe and Thorough Attic Insulation Removal in Marin County
Old insulation isn’t just inefficient — it can be harmful. Over time, insulation materials can become compressed, moldy, rodent-infested, or contaminated with dust and allergens. Before installing new insulation, we often recommend a full attic insulation removal, especially in homes where the existing material is outdated or damaged.
Our insulation removal service in Marin County is thorough and safe. We use high-powered vacuums to extract loose-fill insulation without disturbing your home, and we properly dispose of all materials. If needed, we also offer air sealing, odor neutralization, and preparation for a clean new install. Starting fresh ensures that your new insulation performs as it should — clean, effective, and long-lasting.
