Hot, humid outside air leaks in through every unsealed gap. That moisture loads up your AC and drives mold risk. Stopping the leak is more effective than just adding insulation on top.

Common leak points
Recessed lights, plumbing stacks, electrical wiring, attic hatches, and top plates. Each one is small; together they can equal a wide-open window.
Materials we use
Fire-rated foam around hot surfaces, mastic and caulk on joints, weatherstripping on hatches. Always to manufacturer spec.
