Stone care in Miami
Hot, humid, salty air with intense UV and sudden rain.
Miami's salt-laden air and year-round humidity accelerate efflorescence, mildew, and sealer breakdown on outdoor stone. Indoors, AC swings and citrus-heavy kitchens are the main enemies of marble and travertine.

Frequently asked questions
What stone holds up best around a Miami pool?
Honed granite, dense quartzite, or sealed travertine pavers. Avoid soft limestone unless you're committed to frequent sealing.
Why does my travertine deck keep getting white spots?
That's efflorescence — mineral salts wicking up through the stone. Rinse, let dry fully, and apply a breathable penetrating sealer.
