Drying wet wood in a house is essential to prevent further damage and mold growth. Here are some steps to effectively dry wet wood:

1. Remove any standing water or excess moisture using towels or a wet/dry vacuum.

2. Increase air circulation by opening windows and doors, and using fans or dehumidifiers.

3. Use a moisture meter to monitor the moisture levels in the wood. Ideally, it should be below 20%.

4. If the wood is severely wet, consider using a dehumidification system or professional drying services.

5. Inspect the wood for any signs of mold growth. If present, treat it with a mold remover or call a professional for assistance.

6. Once the wood is dry, assess any damage and consider necessary repairs or treatments to prevent future moisture problems.

By following these steps, you can effectively dry wet wood in your house and minimize the risk of further damage and mold growth.


There are several ways that water can get into the framing, flooring, and other woodwork in your house. It can come from leaks in the plumbing or roof, it can form as condensation from humid air, or it can be the result of a flood. Wet wood can cause damage, but usually, there is enough time to dry it out before permanent damage occurs.

How to Dry Wet Wood in a House

Remember this from the beginning: Wood cannot dry out if it is covered by something wet or if water is still entering. You need to expose the wet wood so that air can circulate around it and address the source of the moisture before the drying process can begin.

Some Water Damage You Can See and Some You Can’t

If there is an active leak or a recent flood, it is easy to identify wet wood. However, some problems are not immediately apparent and only become noticeable through related damage. Moldy or sagging drywall is the most obvious sign of water-damaged wood, but there are other signs such as visible ant infestations.

Water flows downward, so if you have experienced a minor flood or a leak, the bottom of walls and cabinets are the most likely areas to check for damage. Floors are particularly susceptible to moisture. If water seeps beneath the floor covering and infiltrates the subfloor, it can lead to rot and sponginess.

High humidity can cause wet wood throughout the entire house. It can cause passage and cabinet doors to swell, as well as warp door and window casement molding. Dark patches of mold usually indicate the presence of high humidity and potential structural damage.

The Damage Water Can Cause

If you have recently experienced a flood, there may still be standing water on the floor. The Red Cross advises caution as the water may contain pathogens and other contaminants that can be harmful to health. Additionally, the water can make everything dirty.

Even if the water is not pooling on the floor, it provides a suitable environment for mold, rot, and fungus to grow. If the moisture has been present for a long time, the colonies may be well-established. Drying out the wood is the best way to eliminate these colonies, but until then, it is important to avoid inhaling the air. Wearing a mask is recommended.

Mold remediation is necessary after prolonged exposure to moisture. You do not have to wait for the wood to dry out completely to remove the mold, but drying is crucial to prevent its return.

Dealing With Mold

Mold is likely to grow on any wood that becomes wet, and it is important to address mold growth during flood cleanup. The Environmental Protection Agency recommends professional cleanup for mold infestations larger than 10 square feet. Professionals have the necessary tools and expertise, and they can also assist with the drying process.

For localized mold problems, the recommended method is to physically scrub off the mold with detergent and water. Bleach is not necessary as its surface tension prevents it from penetrating the wood and killing the roots. However, if desired, a bleach solution of one part bleach to ten parts water can be used.

To disinfect wood and prevent mold growth, it is recommended to use borate wood treatment powder. This is especially effective for wet wall studs and plates. Sprinkle the borate powder generously on the dry wood before replacing the insulation and drywall.

The first step in drying a house is to remove any standing water. The method for removing it depends on the amount of water. You can squeegee it into a corner and use a mop or sponge to pick it up, or you may need to use a pump.

A wet/dry vacuum is useful for removing standing water, especially from cabinets. Simply vacuum the water into the canister, empty it outside, and clean up any residue with a sponge. The vacuum can also be used to remove water from underneath cabinets and wall plates.

The second step is to expose the wood. If the framing or other structural wood in your house gets wet, the drywall and insulation covering it will also be wet. You need to remove the wet material to allow the wood to dry. Take down any wet drywall and remove the insulation. If there is water damage to the subfloor, remove the floor covering to expose it. If there is a leak in a cabinet, remove everything from the shelves, take out as many shelves as possible, and consider removing the cabinet doors to promote air circulation.

The third step is to circulate the air. Open doors and windows to create a cross draft, as long as the weather is dry and not too cold. Turn on exhaust fans and use portable fans to circulate air at the bottom of the walls and cabinets. Some professionals recommend using a carpet fan to speed up the drying process.

The fourth step is to provide heat. Heat helps to evaporate water faster. Use electric heaters instead of propane ones, as propane combustion increases room humidity and slows down drying. During winter, keep most of the doors and windows closed to retain heat, but open a few windows upstairs to create an updraft and aid evaporation.

Step Five: Utilize a Dehumidifier

A dehumidifier is most effective in an enclosed space, and it is recommended to run one if the wood that needs drying is located in a basement or bathroom. In a large, well-ventilated living room, a dehumidifier may not be as beneficial, but it is unlikely to be necessary either.

A dehumidifier can be extremely helpful for repairing water damage to kitchen or bathroom cabinets. Even though air does not circulate well inside a cabinet, a dehumidifier can still extract moisture effectively. Place it near the opening of the cabinet and operate it at maximum power.

Dealing with Wood Rot

Similar to mold, rot is a microorganism that requires moisture to survive. When you uncover a wall that has been wet for a prolonged period, it is highly likely that you will find rot in the studs and wall plates, especially at the bottom of the wall.

It is crucial to ensure that the wood is completely dry before covering it back up. To expedite the drying process, you can use heat, air circulation, and a dehumidifier. Once the wood is dry, apply borate wood treatment powder to eliminate the rot fungus and prevent future growth.

Repairing rot damage often necessitates replacing the wood, but there may be a simpler solution. You can use epoxy resin wood filler to make the necessary repairs. First, remove the rot using a chisel or screwdriver, and then fill the cavity with the filler material. If epoxy filler is not available, auto body filler can also be used.

Addressing Water Leaks Under Cabinets

Flooded cabinets in the kitchen or bathroom pose a unique challenge because water typically seeps through the cabinet’s bottom onto the floor. This can lead to rot, which can destabilize the cabinet, and mold growth, which poses health risks.

In some cases, it may be necessary to remove the toe kick or the bottom of the cabinet to access the area beneath it. If this is not feasible, it is advisable to move the cabinet instead.

Use a wet/dry vacuum to remove any standing water and then use a sponge mop to clean up any residue. Position a fan beneath the cabinet and leave it there for one to two days to facilitate drying of the floor. Afterward, make any required repairs before covering everything back up.

Water Damage to Plywood and Particleboard

In a high-moisture environment such as a kitchen or bathroom, condensation can cause significant damage to cabinet sides and doors. This includes delamination of plywood and swelling of particleboard, as well as the promotion of mold growth. Once delamination or swelling occurs, replacing the wood is often the only option.

The signs of impending damage are typically evident through brown or black discoloration on the cabinet facing. When this occurs, clean off the mold with soap and water and then utilize a fan, heater, or both to facilitate drying. If you experience chronic issues, explore ways to enhance air circulation around the cabinet.

Window and Door Casings

If you reside in a region with cold winters, condensation may accumulate on the window and door trim. This moisture encourages mold growth and can even cause warping of the trim. This occurs due to the temperature gradient at the door or window, causing water to condense out of the warm indoor air. This problem could be avoided with better insulation of the trim.

To enhance insulation, you can enhance the insulation by eliminating the casing and injecting spray foam insulation into the space between the door or window frame and the wall. Another option is to insert fiberglass batt insulation into the gaps, although this is not as effective. Prevent drafts by applying weatherstripping to the door and window jams. If your budget permits, replacing single-pane windows with double-pane ones also helps.

To improve air circulation in the affected areas, you may consider using a fan. However, this may not be feasible if your house is already cold and you are trying to make it warmer. In that case, an alternative solution is to regularly wipe off condensation with a cloth once a week during the coldest months.
