Deck Building in Alabama — Pro Tips

Schedule exterior work between October and April

Alabama summers run 90°F+ with humidity above 70% — conditions that slow exterior paint drying and strain sealant adhesion. Scheduling staining, painting, and caulk work in the cooler months produces better results and fewer callbacks.
