Local know-how

Homes in Wilmington: what we see

The Delaware climate and what it does to a house.

Delaware has humid summers, coastal storms and winters that swing above and below freezing.

Chimneys & fireplaces

Salt air and wet winters wear out metal caps and flashing, and the freeze-thaw cycle works on the mortar joints.

Roofs

Coastal storms and summer thunderstorms lift shingles. Humidity encourages algae streaks and moss on shaded roofs.

Gutters

Heavy summer downpours overflow undersized or clogged gutters and send water toward the foundation.

Attic insulation

Attic insulation and air sealing help in both the humid summer and the cold, damp winter.
