Drill and Fill Walls

The drill-and-fill process is an effective installation where existing walls (interior or exterior) require insulation upgrading.Small holes are strategically drilled into the wall, between the wall studs. Loose fill insulation fiberglass or cellulose is then carefully blown into the empty wall cavities. On completion, the holes are patched in and the wall finished.

Retrofit drill and fill is an insulating option for many homes. For example, homes built from 1920 to 1960 did not require any wall insulation according to the building code – in the a lot of these cases, the homes had absolutely no wall insulation. For the homeowner with walls that are noticeably cold to the touch (particularly exterior walls) retrofit drill and fill is the solution.

Retrofit drill and fill is an insulating option for many homeowners who are experiencing high heating or cooling costs, the drill and fill upgrade is an ideal option. For those who have uneven heating and cooling throughout their homes, this is also a good reason to upgrade insulation. And in situations where the HVAC system (the furnace and air conditioner) is “overworking”, it’s definitely time to upgrade the insulation. We here at PEC are very well skilled and trained in this area, and have done many drill and fill procedures.
