What a proper install involves

The old unit comes out first, and Judson checks the opening for soft or stained wood.

Any rot at the sill gets cut out and rebuilt before anything new goes in.

Flashing tape goes on the sill, jambs and head, lapped so water always runs outward.

The new unit is shimmed plumb and level, then fastened at the points the maker calls for.

Gaps around the frame get low-expansion foam, which seals without bowing the frame.

Exterior joints are finished with backer rod and sealant, then the trim goes back on clean.

Keeping the mountain wind out

Wind drives rain and snow into weak spots, so the details around an opening matter.

Fog and damp hold against the wall on cool mornings, which tests every seam.

A tight window also helps a home hold heat through long winters in Banner Elk and Beech Mountain.

A sun-side door bakes in summer and freezes in winter, so threshold and weatherstrip matter.

Replacement is also a chance to fix tired trim, so casing is matched to the room inside.
