Weatherization

Gaps around windows, doors, attic hatches, outlets, dryer vents and utility lines let air pass all year. They are small individually and large together, and they are some of the quickest, simplest problems to fix.

We weatherize homes across Nashville and Middle Tennessee. We install door sweeps and weatherstripping, caulk window frames and trim, foam utility penetrations, seal the attic hatch and check every exterior opening so the house closes up.

FAQ

Common questions about weatherization

Is weatherization different from insulation?

Yes. It seals gaps and moving parts, while insulation slows heat flow. Both matter.

Do I need to replace my windows?

Often not. Sealing and weatherstripping can solve most drafts at far less than window replacement.

How long does it last?

Weatherstripping wears with use. We show you what to check each year.
