Fix Hardwood Floor Cupping with Argendon Dehumidifier
Best dehumidifier for hardwood floor protection
Cupping is when the edges of your hardwood floor rise up, creating a bowl-like shape with the center of the plank being lower than the edges. It usually happens when there's uneven moisture around or under the floor, causing the wood to absorb more water on the edges than in the middle
It can start out as a minor issue, but if left unchecked, it can get worse, leading to uneven floors and even damage. Argendon commercial dehumidifiers are designed specifically to pull excess moisture from indoor air and help stabilize hardwood floors before the damage becomes permanent.
Common Causes of Cupping in Flooring
Seasonal Humidity Change
Moisture from Subfloor
A big cause of cupping is moisture rising from below. This can happen if you have a damp concrete slab, a humid crawl space or basement . It’s also common in new construction when the hardwood goes in before the HVAC starts running, meaning the indoor humidity hasn’t stabilized yet. If the underside of your flooring stays more humid than the top, cupping will eventually show up.
Leaks, Spills, or Water Intrusion
Slow leaks around sinks, refrigerators, dishwashers, or ice makers can cause localized cupping that sneaks up on you. Sometimes the leak is so small you don’t even notice it until the floor starts to warp. On the other hand, sudden spills or a quick water accident, like an AC overflow or plumbing issue, can trigger cupping in just a few hours if the moisture isn’t cleaned up thoroughly. A little water left behind can migrate under the boards fast.
How to Fix Cupping in Wood Floors
If cupping is caused by seasonal high humidity or short-term water leakage, running an Argendon dehumidifier will help dry the air quickly and prevent moisture from getting trapped under the boards.
Place large fans on the floor (this helps push moisture into the air) and use a dehumidifier to remove moisture from the air. Most of the time, slight cupping will return to normal if the wood floor isn't too wet.
However, if your hardwood floor has sustained water damage or is severely warped, it’s best to call in a professional to fix it.
Protect Your Hardwood Floors
The image below comes from a real case where an Argendon dehumidifier was used to fix hardwood floors.
Air-Flow, Dry Floor in 4–5 Hours
Fast air circulation blows directly against the hardwood to help dry it out.
Any time you have water on the floor, there’s a risk of mold and mildew.
The sooner you get it dry, the safer your hardwood floor will be.
Ideal for Hardwood Floor Protection
Drying the floor completely is extremely important.
It also comes with a long drain hose — perfect when leaks happen far from a drain.
The dehumidifier pulls moisture out of the air while the fan keeps air moving around the room.
40%–50% Optimal Indoor Humidity
You can set the humidity level to your ideal range, or lower it if you want the room extra dry.
Keeping indoor humidity around 40%–50% helps protect hardwood floors from warping or damage.
