How to Fix Water Damaged Hardwood Floors Easily

Now that you know the cause and signs of water damaged hardwood floors, are you affected? Let’s see the effective method of how to fix damaged hardwood floors and restore your property to its initial state. 


Assess the Damage and Stop the Water

Whether you use bamboo floors, acacia floors, gray hardwood floors, ash floors, maple floors, mahogany floors, or others, they are very beautiful and enhance your home's beauty. However, wood floors can easily be damaged by water.


You need to thoroughly check your house for water damage, such as staining, warping, buckling, swelling, mold, and mildew. For example, if you see sections of wood that look uneven, puffy, swollen, or raised, it is due to slow leaks under the floor. Again, if you are getting a musty smell or seeing fuzzy spots, check for mold growth due to water damage. 


After finding the cause of the water damage, like leaky pipes, backed-up drains, rainwater, flooding, and other issues, you need to immediately stop the water and protect your property from further damage. If the water damage is behind the walls, ceilings, and floors, turn off the water source and call a water damage restoration expert to restore your property. 


Dry and Clean Your Floors Immediately

After stopping the water source, you need to clean and dry the floor ASAP.


You can dry the water using different methods. First, move rugs, mats, and furniture from the damaged area so that trapped water can be dried. Now, 

  • Soak up water using microfiber cloths or a wet/dry shop vac.
  • Open the windows and turn on both the ceiling fans and box fans for ventilation. 
  • Place the dehumidifier near the water-damaged area and use it for 1-2 days to remove moisture from the air and dry the wood.
  • Check under the floor. If the water went under the floor, dry it with a dehumidifier to prevent further damage and mold growth. 

After drying the water, you need to clean the area. Use a high-quality wood cleaner to remove dust, dirt, and mold spores. For example, to remove mold spots, you can use vinegar with a gallon of water. 


Restore Minor Water Damage

With little effort, you can easily fix small water damage like clear white stains, dark stains, cracks, and scratches. 


White Stains 

If you notice white or hazy stains on the floor, use a soft cloth and mineral spirits or denatured alcohol to gently rub on the stain and clean it. If the stain is still not removed, you can also use baking soda. However, for any ingredient you use, do not rub the area harshly. It may leave scratches. 


Dark Stains

When the water has penetrated the wood, it is called dark stains. Getting rid of it is a bit harder than white stains. First, apply the technique below in a small space. If it works, apply it to the affected area. 


Use fine sandpaper to sand the spot lightly. Wipe away the dust with a soft cloth. Find a matching wood color and seal it with polyurethane to restore the property. 


Cracks and Scratches

Use wood filler or a matching wood stain to blend with your existing floor color. Use a small brush to apply filler and wood stain evenly across the area and remove deeper cracks and scratches easily. 


Restore Major Damages

If you have severely damaged boards or mold issues, this section is for you. 


Damaged Boards

If your board is severely water-damaged, replacing it is better than restoring it. 


Evaluate the boards and mark the damaged ones. Carefully cut the boards with a saw, ensuring good boards are not nicked, and remove them. Find similar matching boards, glue or nail them in the right place, sand the new boards to blend, and seal them for long-term use. 


Mold Damage

For expert mold remediation, check where the mold is growing. Remove affected boards to reach the subfloor. Clean the area with a vinegar mix or mold remover. If the subfloor is badly damaged, it is best to replace it. However, if it is not, just clean it properly and set the boards. 


The Final Step- Polishing

You need to polish the repaired water damaged hardwood floors to make them shiny, just like they were in their original state. Also, you need to clean the floors regularly to protect them from water damage and use them safely for a long time.
