Our Mission
Our mission is to help property owners improve suitable existing wall cavities without unnecessary demolition. Cavity wall injection allows cellulose or fiberglass insulation to be installed through carefully placed access points rather than removing large sections of finished walls.
Based in Lompoc, CA, 805 Insulation evaluates the wall construction, available cavity depth, and existing conditions before recommending this approach. Every project starts with determining whether the walls are suitable for drill and fill insulation.
Problems We Solve With Cavity Wall Injection
Older and existing buildings can have wall cavities with little insulation, uneven coverage, or areas that were never insulated properly. Because these cavities are hidden behind finished surfaces, improving them requires a different approach than insulating open framing.
Removing large sections of drywall or exterior finishes can create unnecessary disruption. When wall construction and conditions allow, cavity wall injection provides another way to add insulation while keeping most of the existing wall surface intact.
Our Solution
805 Insulation uses cellulose or fiberglass to fill suitable existing wall cavities. Small access openings are carefully created through drywall or stucco, allowing insulation to be added into the available cavity space.
The amount of insulation that can be installed depends on the wall itself. Available wall depth varies between buildings, so we evaluate the framing and cavity before recommending the work rather than promising the same insulation amount or R-value for every property.

Improve Existing Walls With Less Disruption

Less Invasive Installation
Cavity wall injection allows insulation to be added through carefully placed access openings, avoiding the need to remove large sections of suitable drywall or stucco.

Improved Wall Insulation
Filling suitable empty or inadequately insulated wall cavities with cellulose or fiberglass can help reduce unwanted heat transfer through the treated walls.

Made for Existing Properties
Drill and fill insulation provides a practical option for certain existing buildings where the wall cavities need insulation but the finished wall surfaces are already in place.

17 Years of Experience - Our insulation industry experience helps us evaluate existing walls and determine whether cavity wall injection is appropriate for the property.
Cellulose & Fiberglass - We use cellulose or fiberglass to fill suitable existing wall cavities, selecting the approach according to the wall and project conditions.
Minimal Wall Disruption - Our drill and fill approach uses carefully placed access points through suitable drywall or stucco instead of unnecessarily opening large sections of finished wall.
Precision, Quality, and Lasting Results
Our Process

We evaluate the existing walls, construction, available cavity depth, and accessibility to determine whether wall injection insulation is appropriate.

Our team identifies suitable access locations and determines whether cellulose or fiberglass is appropriate based on the wall cavities and project scope.

We create carefully placed access openings through suitable drywall or stucco and install insulation into the available wall cavities according to the agreed scope.

Once the work is complete, the treated wall cavities have improved insulation coverage designed to help reduce unwanted heat transfer through the walls.
Testimonials
If suitable existing wall cavities have little or inadequate insulation, cavity wall injection may provide a way to improve coverage without opening the entire wall.
