We hired Air Tight Insulation to address serious energy loss in our West Covina home, and the experience was outstanding. Their team used a blower door test to scientifically pinpoint where our home was leaking air. The sealing work they performed was incredibly meticulous—around windows, doors, attic hatches, and all penetrations. The crew was professional, clean, and thorough. Our home now feels solid, quiet, and maintains a perfect temperature. This is true building science expertise.
