This sometimes happens when there’s been a flood that has seeped into the floor.
What causes moisture under hardwood floors. Moisture under hardwood floors is often caused by four factors: If not, the wood may expand or contract after the installation and will lead to the deformation of the wood. If water droplets frequently appear on the surface of wood flooring without an apparent source, it might be because of excess moisture in the board being released.
If the amount is more than what your underlayment can handle, then yes you will need a moisture barrier. Interaction between wood and air is one of those factors. Excess moisture is caused by a number of ways a few being:
In many hardwood floors, the presence of excess moisture can cause a slight discoloration of the wood’s finish. Hardwood flooring cups (edges rise above the center of the board) when there is a moisture imbalance from the top to the bottom of the boards. When relatively warm, moist air comes in contact with a very cool concrete slab, the cold temperature of the concrete will cause the air that comes in contact with it.
When relative humidity (rh) rises, wood absorbs moisture from the air. Ever perceived a musty smell in your home? Concrete is porous and allows moisture to pass through to your basement/room level.
No matter how hard you try, molds will still find a way into the underpart of hardwood floors. Overlap the seams by a foot or more and run the plastic up the sides of the foundation. In environments of high humidity, you can expect your hardwood floors to react accordingly.
Water on or under the floor; The most common is condensation — aka sweating garage floor. If there is a splotchy, mismatched look to the finish of some wood boards compared to others, it may be a sign of moisture intrusion.
What causes moisture under hardwood floors? Water on or under the floor. Water on or under hardwood floors any moisture on or under hardwood floors spells trouble for your flooring.
Mold and mildew thrive on moisture and reproduce by means of tiny, lightweight spores that travel through the air. You'll know there's water under your engineered wood floor when your floorboards start to buckle and warp. Water on or under the floor, high humidity, poor installation, or no acclimation.
Fans and ventilation can reduce buckling, though. Leaking appliances, groundwater intrusion, condensation, and moisture from the concrete subfloor can all be sources of moisture. Some pests, like termites, thrive in wood that has excess moisture.
Acclimation should be done first before installing the hardwood floors. When rh falls, wood loses moisture to the air. The effects of moisture and humidity on hardwood floors the effect of moisture and humidity on hardwood floorsmoisture problems in wood floors can be caused by many different factors.
These are some of the most common causes: Mostly concrete subfloors transmit moisture. Water and moisture can cause the flooring to become warped and permanently damaged.
If wood floors are placed directly on concrete with no vapor barrier installed underneath, humidity will pass through the porous concrete. If moisture under hardwood floor is not tackled, this can lead to mold and eventually damage your floor. What causes moisture under hardwood floors?
If it doesn’t exceed the amount, then the underlayment can handle the job. This is a completely natural process, but excessive mc changes can cause damage to hardwood floors. As a result molds settle down under hardwood floors from the air.

Your wooden floor can absorb moisture from the air, and this will cause the wood to expand and to buckle. Most problems with wood floors are caused by too much moisture. There are several common causes of moisture permeating hardwood flooring.
In many types of hardwood flooring, excess moisture can cause the wood to appear slightly darker than it should be. Wood is hygroscopic and vulnerable to moisture, leading the boards to peel away from the subfloor and can cause discoloring on. Typically, hardwood floors are not recommended if you live in areas with high humidity.
If droplets of water continuously form on the hardwood floor’s surface with no apparent source, it may be an indicator that there is excess moisture within the boards. Mold and mildew will develop within 24 to 48 hours of water exposure. Molds are various fungi that cover surfaces as fluffy mycelia and usually produce tons of asexual or sometimes sexual spores.
For extreme moisture problems, consider taping the seams in the plastic together, block the outside vents, and install a dehumidifier in the crawlspace to remove excess moisture from the air. Dishwashers, refrigerators, washing machines and water heaters; The reason is, hardwood floors are organic and their underpart has tons of trapped moisture.
Wood floors experience cupping when moisture becomes trapped underneath the wood. Crawl space moisture and hardwood flooring crawl space moisture and hardwood flooringto understand the cause of wood floors cupping or buckling (when you’re sure there is no water damage due to a flood or leak), you must understand the relationship between relative humidity, your wood floor and your crawl space.during the summer months in the northeast region, wood subfloors. Because the core of engineered wood flooring is not resistant to water, the floor will become damaged if water is allowed to soak into it.
As we mentioned earlier, the cause for the moisture on or under your hardwood floors can come from a variety of things and/or circumstances. Wood is a hygroscopic material, which absorbs or looses moisture until equilibrium with the surrounding air has been reached. Also asked, what causes moisture under hardwood floors?
