How Coastal Georgia's Humidity Affects Your Flooring Choice

If you've lived in Savannah, Pooler, Richmond Hill, or anywhere else along our stretch of the Georgia coast for more than a summer, you already know the air here does things air in most of the country doesn't. Thick, wet heat for half the year, salt air near the marshes, and humidity that regularly sits above 70% — it's rough on a house, and flooring takes more of that abuse than almost anything else inside it.

We get asked constantly which flooring "holds up" here. The honest answer is that some materials are built for this climate and some genuinely aren't, and picking the wrong one can mean gaps, cupping, or a warped floor within a year or two — not decades of slow wear.

Why Humidity Hits Flooring So Hard Here

Wood-based flooring is hygroscopic, meaning it absorbs and releases moisture from the surrounding air. When humidity swings the way it does on the coast — muggy summers, drier winters, and AC units cycling on and off all day — wood-based floors expand and contract right along with it. Do that enough times and boards start to cup, crown, or open up gaps at the seams. Add a slab foundation with residual moisture, a bathroom, or a laundry room, and the problem gets worse.

Materials That Handle Our Climate Well

• Luxury vinyl plank (LVP) — fully waterproof core, dimensionally stable regardless of humidity
• Porcelain and ceramic tile — unaffected by moisture, the standard for bathrooms and mudrooms here
• Engineered hardwood — its cross-layered core resists the expansion and contraction that ruins solid wood
• Waterproof laminate with a sealed core — a step up from standard laminate in humid rooms

These are the products we install most often for homes near the marsh, on a slab, or anywhere a client tells us their old floors "always feel damp" in July and August. They're not just marketed as humidity-resistant — the way they're built physically prevents the swelling and buckling that solid wood is prone to.

Materials That Need Extra Care

Solid hardwood isn't off the table on the coast, but it needs the right conditions: consistent indoor humidity (ideally 35–55%), proper acclimation before installation, and a moisture-managed subfloor. Skip any of those steps and even a beautifully installed solid hardwood floor can start showing gaps by its second summer. Standard (non-waterproof) laminate is the other one to watch — its core can swell permanently if it's exposed to standing water or chronic high humidity, which makes it a poor fit for kitchens, bathrooms, or ground-level rooms near the coast.

Signs Humidity Is Already Affecting Your Floors

• Boards that feel higher in the middle than at the edges (cupping)
• Visible gaps between boards that widen and narrow with the seasons
• A soft, spongy, or uneven feel underfoot near exterior walls or bathrooms
• Laminate that looks swollen or "puffy" along the seams

Any of these usually means moisture is getting into the floor from below, above, or the air itself — and the fix is almost always addressing the moisture source, not just replacing the boards, or the same damage comes back.

Our Take

For most homes in the Savannah, Pooler, Rincon, Springfield, Statesboro, and Guyton area, we steer clients toward LVP, tile, or engineered wood in any room touching a slab, bathroom, or ground floor — and reserve solid hardwood for climate-controlled upper levels where humidity swings are smaller. The right call really does depend on your specific house, foundation, and how the space is used, which is why we walk the room with you before recommending anything.
