Living in South Florida comes with year-round sunshine and coastal beauty, but it also brings consistently high humidity levels. While the climate is great for tropical plants and beach days, it can pose serious challenges for woodwork inside your home—especially your cabinetry.
At Delta Woodworks FL, we specialize in crafting custom cabinetry built to withstand Florida’s unique climate conditions. In this article, we’ll explain how humidity affects wood cabinets, what signs to look for, and how to protect your investment over time.
Why humidity impacts wood cabinets
Wood is a natural, porous material that responds to changes in moisture levels. In a humid environment like South Florida’s, wood tends to absorb moisture from the air, causing it to expand. When the humidity drops, the wood releases moisture and contracts. This constant cycle of expansion and contraction can lead to a variety of structural and aesthetic issues.
Common problems caused by humidity
Swelling and warping
Excess moisture causes wood to swell. Cabinet doors may no longer close properly, drawer faces can become misaligned, and visible warping may occur, especially in softer woods.
Cracking and splitting
When humidity drops suddenly (such as from indoor air conditioning), previously expanded wood may contract too quickly, leading to surface cracks or joint separation.
Finish damage
High humidity can cause finishes to bubble, peel, or become sticky to the touch. It can also dull the appearance of paint or stain over time.
Mold and mildew growth
In poorly ventilated kitchens or bathrooms, high humidity levels can encourage mold or mildew growth behind and beneath cabinets, especially if condensation builds up near plumbing.
How to protect your wood cabinets in a humid climate
Choose the right wood type
Some hardwoods are more stable than others. Maple, cherry, and oak are popular choices for Florida homes because they expand and contract less than softer woods like pine.
Use high-quality finishes and sealants
Water-resistant finishes and professional sealing methods can add an extra layer of protection to your cabinets. This helps prevent moisture from penetrating the wood surface.
Maintain indoor humidity levels
Use a dehumidifier or properly calibrated HVAC system to keep indoor humidity between 35% and 55%. This creates a stable environment that helps prevent wood movement.
Ensure proper ventilation
Install or maintain exhaust fans in kitchens and bathrooms. Adequate airflow helps reduce excess moisture in areas where humidity tends to build up the most.
Clean and inspect regularly
Regularly inspect cabinet surfaces and joints for signs of warping or moisture damage. Clean with a soft, dry cloth and avoid using excessive water during maintenance.
Final thoughts
Humidity is a fact of life in South Florida, but it doesn’t have to damage your home’s cabinetry. With the right wood choices, finishes, and care routines, your custom cabinets can stay beautiful and functional for years to come.
