The Leaks You Cannot See Are Costing You

A typical home has dozens of small openings where air moves in and out: top plates, wire and pipe penetrations, recessed lights, attic hatches, rim joists and around windows and doors. Added up, they can equal leaving a window open all year.

Air sealing finds and closes those paths. It is one of the highest-return, lowest-cost steps you can take, and it makes every other insulation upgrade work better.

A Continuous Air Barrier

We target the specific places air moves through your building envelope and seal them with the right material for each spot, from foam at large gaps to caulk and gaskets at smaller ones.

The goal is a continuous air barrier that keeps conditioned air in and outside air, moisture, dust and pollen out.

Where Air Sealing Pays Off

Attic plane

Top plates, penetrations and the attic hatch, where warm air escapes upward.

Rim and band joists

A major, often ignored leak point in the floor system.

Around openings

Windows, doors and where different materials meet.

Utility penetrations

Wiring, plumbing and duct chases that pass through the envelope.

What Affects Air Sealing Cost

Air sealing is usually one of the most affordable improvements. Cost depends on:

  • Size of the home
  • Number and type of leak points
  • Access to attics, crawl spaces and rim joists
  • Whether it is paired with an insulation upgrade
  • Condition of existing materials

Air Sealing FAQ

Is air sealing really worth it?
Yes. It is one of the best returns in home performance because it is low cost and makes your insulation, comfort and equipment all work better. It is often the first thing we recommend.
Do I still need insulation if I air seal?
They work together. Air sealing stops air leakage; insulation slows heat transfer. Doing both gives you the comfort and savings people expect from an upgrade.
Will it help with dust and allergies?
Often, yes. Sealing the envelope reduces the unfiltered outside air and dust that sneak in through gaps.
How long does it take?
Most homes can be sealed in a single visit. We confirm the timeline after we see the home.
Can you air seal an existing home?
Yes. Retrofitting existing homes is the most common air sealing work we do.
