Drill & Fill Insulation

Upgrade your wall insulation & reduce your high energy bills

Today, there are many residential homes (both old and new) that are being “retrofitted” with insulation. An insulation retrofit is simply an upgrade to ensure that “conditioned” air is kept within the home. In the winter, it means keeping warm air from escaping to the outdoors, and in the summer, it means keeping the cooled air from escaping. The insulation creates energy efficiency.

Drill & Fill Insulation Process:

  • Depending on your home, drilling will either be from the inside or outside of the house.
  • One- to two-inch-diameter holes are drilled into each bay.
  • One installer operates the hose to fill each hole while a second installer operates the blowing machine.
  • The two installers use cellulose insulation to fill each bay of a wall, providing maximum insulation.
  • After all holes and bays are filled with cellulose insulation, each hole is patched up.

Drill & Fill Insulation For Older Homes

Homes built before 1979 typically have little or no wall insulation. In many homes, batt insulation can only provide incomplete insulation, which allows more heat to escape. The answer to incomplete wall insulation is the drill-and-fill process.

Every spare spot on a wall can be filled with a drill and insulation, which is not always possible using just batt insulation. Filling every bay with insulation ensures maximum insulation benefits. This allows the highest possible R-value for wall insulation. R-value measures how effectively insulation performs in various parts of the home. Drill and fill techniques can be used to re-insulate the walls and provide maximum R-value coverage in older homes that may already have old wall insulation.

Insulation Commandos did a great job with my attic insulation replacement. They protected the floor and walls carefully, finished the job in an efficient timely manner and and cleaned up afterwards. Thank you!

Insulation Commandos did an excellent job. They removed and took away debris, vacuumed, sanitized and plugged rodent holes. They left traps to ensnare any stray rodents. They arrived exactly on time and finished sooner than we expected.

I recently had Insulation Commandos and rodent-proof my attic and replace the insulation and heating ducts. They also cleaned and insulated the crawl space and installed a vapor barrier. Throughout the process, they were pleasant, professional, and responsive; they handled the project swiftly and the work was performed in a careful (and clean) manner. I am happy to recommend them

This company is AMAZING! From the first encounter with the salesman to working with the installers, my experience was excellent! I had my old (35-year-old) insulation removed, my old ductwork removed, and all new installed. The process was flawless, and I was very happy with the work done
