A Locust Grove Crew That Only Does Insulation
Founded by Jose Ferrera and built over ten years of attics, walls, and metal buildings across Metro Atlanta. One trade, done properly, every day.
One trade, done properly, every day
Allstar Insulation started with one truck, one spray rig, and a simple observation: most of the houses south of Atlanta were losing money through the attic. Ten years later we're still based in Locust Grove, still owner-run, and still on the job site every day, but the crew has grown and the work now runs from single-attic top-offs to full commercial shells.
We install three systems and nothing else: spray foam, batt, and blown-in. That focus matters. It means the crew spraying your roof deck has sprayed hundreds before it, knows how Georgia humidity behaves in a closed attic, and knows exactly how deep the foam needs to be for the R-value on your estimate.
We're licensed and insured, we put every number in writing before work starts, and we walk the finished job with you before we pack up. That's how we'd want it done in our own homes.
What we stand for
Six standards we hold ourselves to on every project — big or small.
Installed to Spec
The depth and R-value on the estimate are the depth and R-value in the attic.
Straight Answers
If blown-in will do the job, we won't sell you spray foam.
Respect for Your Home
Masked, contained, and cleaned up before we leave.
Kept Schedules
A real install date, and a crew that shows up on it.
Measured, Not Guessed
Depth gauges and markers on every job so you can verify the work.
Built for Georgia
Materials and methods chosen for our heat and humidity, not a generic spec sheet.
A better service experience, by design
Generic promises are easy. We focus on the habits that actually make the difference.
