Drafts are only part of the story.

Start with the simplest upgrades first.

Then inspect the perimeter seal, because compression-style weatherstripping usually holds up better than bargain adhesive strips in a humid climate.

Heat can warp some materials, and constant sun exposure can dry out seals, especially on south- and west-facing entries.

If you are comparing best entry door materials for South Carolina climate, fiberglass tends to balance durability, stability, and thermal performance well, while steel can be efficient but needs good finish maintenance to resist dents and surface wear.

That is why good installation matters as much as the product itself.

Older homes sometimes have settled openings, uneven floors, or layers of prior repairs that hide air leaks.
