What we seal.

Top plates

The top of every interior wall connects to the attic. That gap runs the full length of the wall.

Recessed lights

Each one is a hole through the ceiling into the attic.

Plumbing stacks

Every pipe that passes through has a gap around it.

Wire penetrations

Every wire, junction box, and cable run.

Duct chases

Large open cavities built to hide ductwork.

Attic hatch

The access point itself is rarely sealed or insulated.

Air sealing is included in every insulation and restoration job. It is not an add-on.

Why it matters.

Your attic floor has dozens of small gaps. Individually they seem minor. Added up, they can equal one to two square feet of open space to the attic.

Heated and cooled air moves through those gaps constantly. The EPA estimates that sealing them can reduce heating and cooling costs by 15%.

Insulation slows heat transfer. Air sealing stops air movement. Both need to happen for either one to work properly.

Common questions

What is air sealing?

Closing every gap and crack in the attic floor where air passes between your living space and the attic. Around pipes, wires, lights, walls, ducts. Done with foam, caulk, and metal flashing depending on the location.

Is air sealing included in the job?

Yes. Every insulation and restoration job includes air sealing. It is part of how we work, not something extra.

Can I just add insulation without air sealing?

You can, but the insulation will not perform the way it should. Air moves through the gaps underneath it regardless of how much insulation sits on top.

How do I know if my attic needs air sealing?

If your home was built before 2000, it almost certainly has unsealed penetrations. The inspection will show you exactly where the gaps are.
