Cold Weather and Your Floors: What Actually Happens in Louisiana & East Texas

Why Winter Is Worth Thinking About for Your Floors

The Ark-La-Tex doesn't get the extended severe winters that affect the northern half of the country — but we get enough cold to affect floors, particularly because our homes move quickly between temperature extremes. A Louisiana home might go from 75 degrees and high humidity in October to 35 degrees and dry heating air in January. That swing is enough to cause real changes in flooring materials, especially wood.

This guide covers what cold weather actually does to the most common floor types in our market and what warning signs indicate a problem versus normal seasonal behavior.

Hardwood: The Most Cold-Weather-Sensitive Product

Wood shrinks as it loses moisture to dry winter air and expands as it absorbs moisture in humid conditions. In a properly installed and well-maintained hardwood floor, this seasonal movement is built into the installation — expansion gaps at the perimeter allow the floor to move without buckling or cracking.

What you'll see in winter that is normal: small gaps between planks, particularly in solid hardwood floors. This is the wood contracting as the relative humidity drops with heated indoor air. In most cases, these gaps close back up in spring and summer when humidity returns. This is not a defect — it's wood behaving as wood does.

What you'll see that indicates a problem: gaps that are unusually wide (more than 1/8 inch in multiple planks), gaps that don't close when humidity returns in spring, or cracking in the surface of individual planks. These can indicate that the floor wasn't properly acclimated before installation, that the subfloor moisture was too high when the floor was installed, or that a heating system is creating extreme dry conditions in one area of the home.

What helps: A whole-home humidifier during winter months keeps indoor relative humidity in the 35–50% range, which significantly reduces seasonal movement in hardwood floors. This is especially relevant in Shreveport and Bossier City homes with forced-air gas heating, which can drive indoor humidity very low during cold snaps.

LVP: More Stable, But Not Immune

SPC-core LVP is significantly more dimensionally stable than hardwood — it expands and contracts far less with temperature and humidity changes. But it's not immune.

LVP has a temperature range within which it's designed to perform. Below that range (typically around 55–65°F for most products), the click-lock joints can become brittle and more prone to damage from impact. This rarely matters in a conditioned home. It matters for spaces that aren't heated — garages, lake cabins, vacation properties — where temperatures may drop below the product's specified range.

If you have LVP in a space that gets very cold in winter and you notice the joints pulling apart slightly at the seams, that's thermal contraction. Returning to normal temperature usually closes the gaps. Persistent gaps after temperatures normalize warrant a closer look.

Tile: The Most Cold-Weather-Stable Option

Porcelain and ceramic tile are the most cold-weather-stable flooring options. The tile itself doesn't move appreciably with temperature changes. What can be affected is the grout.

In bathroom tile floors specifically, temperature-driven movement between the tile and the subfloor can stress grout joints over years of thermal cycling. Hairline cracks in grout that appear in winter are often the result of this movement — not improper installation, but normal long-term behavior. Regrouting affected areas is straightforward.

For exterior tile — patios, entryways, covered outdoor areas — make sure the tile specified is rated for freeze-thaw cycles. Not all porcelain tile is rated for this. In East Texas and Louisiana, we don't get extended hard freezes, but the occasional dip into the low 20s can crack a non-freeze-rated tile that has absorbed water.

What to Watch For This Winter

• Hardwood gaps: Small gaps between planks are normal. Wide or persistent gaps warrant a call.
• LVP joint separation in unconditioned spaces: Usually closes when temperatures normalize. Persistent gaps after warming warrant attention.
• Tile grout cracking: Normal long-term behavior in high-movement areas. Regroutable.
• Squeaky floors in winter: Wood subfloors shrink slightly in dry winter conditions, which can create movement between the subfloor and finish floor. Usually resolves in spring.
