Texas is known for its extreme weather—scorching summers, high humidity, and sudden weather shifts. While homeowners and business owners adapt to these conditions, many don’t realize how much the Texas climate affects wood. Whether it’s custom cabinetry, flooring, trim, or furniture, wood reacts to temperature and moisture changes. Without proper care, this can lead to warping, cracking, or even mold growth.
Understanding how heat and humidity impact wood and how to protect it will help ensure your investment in custom millwork stands the test of time.
How Texas Heat Affects Wood
Expansion and Contraction
Wood is a natural material that absorbs and releases moisture from the air. In extreme heat, especially during Texas summers when temperatures regularly exceed 100°F, wood dries out faster. As moisture evaporates, wood shrinks, which can cause gaps in flooring, cracks in furniture, or misaligned cabinet doors.
When temperatures cool down or humidity increases, the wood absorbs moisture again, causing it to expand. This constant cycle of expansion and contraction stresses the wood, leading to long-term damage.
Increased Risk of Splitting and Cracking
When wood dries out too quickly due to high heat, it becomes brittle. This makes it more susceptible to cracks, especially in solid wood furniture and flooring. Fine millwork details, such as crown molding or intricate carvings, are particularly vulnerable because they rely on precise dimensions to fit together seamlessly.
Fading and Discoloration
Direct sunlight, which is common in Texas homes with large windows or outdoor living spaces, can cause wood to fade over time. UV rays break down the wood’s natural fibers and finish, leading to discoloration and a dull appearance. Lighter woods, such as maple or ash, are particularly prone to fading, while darker woods may take on an uneven, weathered look.
How Texas Humidity Affects Wood
4. Keep Wood Away from Direct Sunlight
Whenever possible, position furniture, cabinets, and millwork away from direct sunlight. Use curtains, blinds, or UV-filtering window films to reduce sun exposure and prevent fading.
5. Allow Wood to Acclimate Before Installation
If you’re installing new flooring, cabinetry, or trim, allow the wood to adjust to your home’s climate before installation. This means letting it sit in the space for a few days to a week so it can adapt to the temperature and humidity levels. This reduces the risk of expansion or contraction after installation.
6. Maintain Proper Ventilation
Good air circulation helps prevent moisture buildup. Use exhaust fans in kitchens and bathrooms, and make sure furniture isn’t placed too close to walls, which can trap moisture and encourage mold growth.
How to Protect Your Wood from Texas Heat and Humidity
1. Choose the Right Type of Wood
Not all wood reacts the same way to heat and humidity. Hardwoods like oak, maple, and hickory are more stable than softer woods like pine. If you’re investing in custom millwork, ask about wood species that are naturally resistant to warping and moisture damage.
2. Apply Proper Finishes and Sealants
A high-quality finish acts as a protective barrier against moisture and UV damage. Polyurethane, lacquer, and oil-based finishes help seal the wood, reducing its ability to absorb or lose moisture too quickly. If your woodwork is exposed to direct sunlight, consider UV-resistant finishes.
3. Control Indoor Humidity Levels
Maintaining a consistent humidity level indoors can prevent wood from expanding and contracting too much. Using a dehumidifier in humid months and a humidifier in dry months can help stabilize conditions. Ideally, indoor humidity should stay between 35% and 55%.
