Many homeowners desire wooden flooring due to their aesthetic designs, durability, and convenience, and are willing to spend thousands of dollars. Well maintained hardwood floors can last for generations; however, it is durable but not invincible and requires regular care and maintenance.
Wood is a natural material, and even after being transformed into flooring, it is sensitive to environmental factors such as extreme temperatures and high humidity. When moist Wood expands, but it contracts again when the air is dry and temperature drops. Hardwood floors dry out when there is not enough moisture in the air. Laminate flooring solid woods and even engineered flooring are all vulnerable to the effects of humidity.
Manufacturers recommend that humidity should be kept between 40-70%
How Humidity Affects Wood
As per the National Wood Floor Association (NWFA), 90% of wood flooring failures are related to relative humidity and moisture problems.
Consistently high humidity can swell Wood by as much as 15%. During warm and humid summers, the hardwood floor absorbs moisture from the air, swelling, and expanding, creating pressure between the boards, and causing the boards to warp, cup, or crack. Some of the hardwood floor moisture problems are as mentioned below:
Gapping
When relative humidity is lower than recommended levels, wood plank shrinks, therefore, thin gaps can appear between wood planks. Once the moisture level becomes routine, the hardwood floor expands, and most gaps will close automatically.
Splits & Checks
When the floor wood experiences extreme environments, it becomes stressed and deteriorates, making the hardwood floor brittle, and increasing the likelihood of damage. The wooden board may split, check or crack in the center or at the ends, or damage the grain’s finish.
Cupping
With a disproportionate humidity level or water spillage into the wood plank, the floorboards’ edges swell, and curl upward, becoming higher than its center, making the board appear like a cup. Other reasons for cupping include relative humidity migrating from a basement or crawl space, water infiltration, etc.
Crowning
Crowning is the opposite of cupping, where the center expands upward, and the edges remain flat. The causes of crowning include excess moisture from humidity, spills, or wicking moisture from the sub-floor. Another reason for crowning is if the floor is sanded too soon after cupping.
Buckling
Buckling is a relatively rare but severe condition usually caused by extreme events such as flooding or plumbing issues. The buckled floor expands beyond gaps and pulls away several inches from the subfloor, creating high and low spots. Once the humidity drops, the Wood shrinks back, but some space may remain between the wood boards. In most cases, the buckled planks need to be replaced.
Cracking
When Wood expands due to high moisture, boards start pressing against each other. In extreme cases, this increased pressure can lead them to crack. Even if the humidity is restored at a reasonable level, it may take some time for the Wood to come back to its original shape.
Preventing Hardwood Floor Moisture Problems
Even when it’s treated and sealed, Wood is still a porous, fibrous material and is reactive to moisture content (MC) in the surrounding air. If the air is humid, the Wood will absorb moisture and swell. If the air is dry, wood fibers will release moisture partially back into the air and shrink. While optimal humidity for interior conditions can change for different types of Wood, seasons, and climates, it’s ideal for keeping moisture somewhere between 40 to 60% to minimize contraction and expansion.
Keeping the humidity and temperature level at the recommended level is essential for maintaining the hardwood floor, and is also advisable for a healthy home environment. Regularly monitor the humidity levels with a digital hygrometer. Most hardwood floor manufacturers recommend humidity levels of around 35%.
How to Regulate Humidity for Hardwood Floors
Humidity in the house is continuously vacillating. If you live in a wet area with high humidity levels or have a home with a basement, it is ideal to use a Dehumidifier. If you live in a place with humid summers, you may need to run it seasonally to keep your wood floors in top shape year-round. The key is controlling the climate in your home, keeping it as consistent as possible.
Excess moisture is detrimental for wood floors but everyone’s health. Mold can grow inside of floors, walls, and ceiling spaces. Installing hardwood floors in basements or over crawl spaces can be challenging unless you have a dehumidifier working. Dehumidifiers can be attached to the central heat and air conditioning unit or portable for use in one room.
The NWFA advises that relative humidity levels range from 30 to 50% for hardwood floors’ best performance and life span. The NWFA estimates that relative humidity issues cause approximately 90% of hardwood flooring failures in the home. Many wood flooring manufacturers will require homeowners to maintain correct relative humidity in the house to keep their warranty active.
Use a Dehumidifier
When a dehumidifier is left on an automatic setting, it will remove excess moisture from the air. This will significantly reduce the amount of moisture your wood flooring will absorb, and most automatic settings will maintain humidity at around 50% RH.
Dehumidifiers are designed expressly to remove moisture. They pull air in across cooling coils and collect the moisture. The cooled air is then reheated and returned to the room for better redistribution. Dehumidifiers have one-tenth of the demands of AC units. Some of the latest models also feature humidistats so you can set the desired humidity levels.
