Florida’s sunshine and sea breezes come with a challenge every homeowner knows: humidity. Whether you live on the Gulf or the Atlantic side, year-round moisture in the air affects everything from drywall to décor—and especially flooring.

At Bell Service Group LLC, we’ve seen firsthand how humidity can quietly warp wood, loosen vinyl planks, and stress adhesives. Here’s how to understand the science behind it and how to keep your floors in perfect condition through every season.

Why Humidity Matters

Humidity is the amount of water vapor in the air. When levels rise, flooring materials—especially wood—absorb that moisture. When humidity drops, they release it. This constant expansion and contraction can lead to cupping, crowning, gapping, or buckling over time.

Wood floors are hygroscopic, meaning they naturally absorb moisture.
Luxury Vinyl Plank (LVP) and laminate can lift or separate if humid air seeps beneath.
Tile and stone are less affected but the grout beneath them can still trap moisture.

That’s why manufacturers and the National Wood Flooring Association (NWFA) recommend maintaining a stable indoor relative humidity (RH) range between 35–55 %.

Florida’s Climate Challenge

Coastal Florida’s RH often hits 60–90 %. Add air-conditioning, sea breezes, and seasonal storms, and your home can cycle through extremes daily. In summer, high outdoor humidity can push into cool, dry indoor spaces—condensing on floors and walls. In winter, AC or dehumidifiers may make air too dry, causing gaps in wood floors.

Smart Prevention and Control

Monitor Indoor Humidity

Place digital hygrometers on each floor of your home. Models from brands like ThermoPro or Govee cost under $20 and connect to apps that alert you when levels drift out of range.

Run a Dehumidifier in Peak Season

In Florida’s summer, a whole-home or stand-alone dehumidifier helps your HVAC maintain balance. Look for ENERGY STAR-rated units sized for your square footage.

Keep Air Flowing

Ceiling fans, open interior doors, and a well-maintained HVAC system prevent moisture pockets that can damage floors in closed-off rooms.

Use Area Rugs and Mats Wisely

Rugs are great for style and comfort, but avoid rubber backings that trap moisture. Choose breathable materials like cotton or woven jute and lift them monthly to let the floor breathe.

Acclimate Your Flooring

Before installing wood or laminate, store it inside your home for 3–5 days so it can adjust to the ambient RH and temperature. This reduces post-install movement.

Design Insights for Humid Climates

Engineered wood is more dimensionally stable than solid hardwood. Its cross-ply layers resist movement from moisture.
Luxury vinyl plank (LVP) with a rigid core handles humidity well while delivering a wood look.
Tile and stone remain top choices for bathrooms, entryways, and coastal zones where humidity and sand mix.
Matte finishes disguise minor movement better than high gloss.
