Steps to Repair Water-Damaged Hardwood Floors
Here’s a step-by-step guide to repairing water-damaged hardwood floors, compiled from the top online resources:
- Stop the Water Source: The first and most important step is to identify and stop the source of the water damage. This might involve fixing a leaky pipe, repairing a roof, or simply cleaning up a spill.
- Remove Excess Water: Use a wet/dry vacuum, towels, or a squeezer to remove as much standing water as possible. Using a wide attachment with a vacuum hose can effectively remove most surface water. Another option is to use a water vacuum, which sucks up all the water in the affected area. The longer the water sits, the more damage it will cause. For minor water damage wood floors, quickly removing the water with a shop vacuum can be a simple first step.
- Dry the Area: Use fans, dehumidifiers, and open windows to thoroughly dry the affected area. In addition to fans and dehumidifiers, experts recommend laying thick towels over the affected areas and pressing down to absorb any remaining moisture. This process can take several days, so be patient. Avoid using heat to speed up the drying process, as this can damage the wood.
- Clean and disinfect: Clean the floor with a mild wood floor cleaning solution or a mixture of detergent, water, and disinfectant. If your floor has been painted, you may notice paint peeling off during the cleaning stage. If you see any signs of mold, use an abrasive cleaner and a mold treatment solution.
- Assess the Subfloor: Remove a few floorboards to inspect the subfloor for moisture, mold, or rot. Water can get under hardwood floors if there are cracks in the subfloor. If the subfloor is damaged, you’ll need to repair or replace it before proceeding.
- Repair or replace damaged boards: If the damage is severe, you may need to replace some of the hardwood planks. Replacement wood floors can cost from $6 to $25 per square foot, depending on the material. You can find replacement boards at most hardware stores. Be sure to match the species and finish of your existing flooring. If the floor is swollen due to humidity, install ventilation fans or use a dehumidifier to dry out the room and speed up the drying process.
- Sand the Floor: Once the floor is dry and any damaged boards have been replaced, sand the affected area to create a smooth and even surface. Start with coarse-grit sandpaper and gradually move to finer grits. For painted floors, remember that mold can easily grow under the surface paint, so additional mold treatment may be necessary after sanding.
- Fill Gaps and Cracks: Use wood filler to fill any gaps, cracks, or holes in the floor. Choose a filler that matches the color of your wood.
- Stain and Refinish: If necessary, stain the floor to match the original color. Then, apply a polyurethane finish to protect the wood and give it a glossy look. Most stain-resistant wood floor sealers are oil-based and increase the floor’s water resistance. You may need to apply multiple coats, sanding lightly between each coat.
| Sealant Type | Advantages | Disadvantages |
| Oil-Based Sealants | Offer excellent water resistance and durability. They penetrate deep into the wood, providing long-lasting protection. | May have a strong odor and take longer to dry. |
| Water-Based Sealants | Environmentally friendly and dry quickly. They provide a clear finish that doesn’t yellow over time. | May not be as durable as oil-based sealants. |
- Polish: Once the finish is dry, polish the floor to restore shine.
