Drill & Fill Insulation for Existing Walls and Older Homes

Tech Drill Filling Insulation

Upgrade Your Walls. Boost Your Comfort. Lower Your Energy Bills.

Older homes and buildings often lack proper wall insulation — or have none at all. That means heat escapes in the winter and sneaks in during the summer, making your HVAC system work overtime and leaving your home uncomfortable year-round.

At SRI Energy, we help homeowners and property managers throughout the Tulsa Metro Area solve this problem with drill and fill insulation — an easy, effective way to add insulation to existing walls without tearing them open.

What Is Drill & Fill Insulation?

Drill and fill insulation is the process of adding insulation into the wall cavities of existing homes or buildings. Small access holes are drilled between the wall studs, insulation is blown into the cavities, and then the holes are patched and finished neatly.
This technique allows you to improve your home’s energy efficiency without the cost or hassle of major renovations — perfect for older homes, rental properties, and multi-family buildings.

Benefits of Drill & Fill Insulation:

  • Lower Energy Bills — Fill the gaps in your wall insulation and stop energy loss where it happens most.
  • Improve Year-Round Comfort — Eliminate those frustrating cold drafts in the winter and overheated rooms in the summer.
  • No Major Renovation Needed — Add insulation from the outside or inside with minimal disruption to your home or tenants.
  • Reduce Outside Noise — Enjoy quieter, more peaceful living spaces by reducing noise transfer through the walls.
  • Fast, Professional Installation — Our certified team handles the job quickly and leaves your space clean and intact.

Polite, Professional, and Detail-Oriented from Start to Finish!

The two SRI Energy associates that came to my house were very professional. When they arrived, they identified themselves and shook my hand. They did an excellent job and even pointed out some thing small that I need to call an electrician on. They were very neat and cleaned up even the smallest of smudges on the door that goes up to the attic.
A different associate First came out to give me an estimate on the job that I needed done. He, as well, identified himself. And shook my hand. Very very polite employees. I highly recommend SRI ENERGY and I will definitely refer them to others.
