How to Repair Water Damaged Wood Floors






Did you know that 15 million U.S. homes are at risk of flooding? These floods can destroy everything, even the floor materials. Water damaged wood floors are the worst!

Not only is the wood at risk of becoming moldy underneath, but it might mold in places you can see as well. This is because it is composed of wood cellulose, which is great for holding water, both inside the wood and around it.

Luckily, if your wood floors have been damaged by water, there is hope. Read on how you can repair water damaged wood floors.

Causes of Water Damage on Wood Floors

Water damage to wood floors can be a homeowner’s worst nightmare. Not only is it unsightly and affects the overall aesthetic of the home, but it can also lead to costly repairs and even permanent damage if not addressed.

Understanding the causes of water damage on wood floors is crucial in preventing and repairing any potential issues. Here are some examples:

Plumbing Leaks

One of the most common causes of water damage on wood floors is plumbing leaks. Whether it be a burst pipe or a small leak under the sink, these can cause significant damage to your flooring if left untreated. It is important to check for any signs of leaks, such as damp spots or discoloration on your floor, and address them.

Appliance Malfunctions

Another culprit for water damage to wood floors can be malfunctioning appliances, such as dishwashers, refrigerators with ice makers, or washing machines. If these appliances leak or overflow onto your flooring, it can cause irreversible warping and staining. Inspect these appliances for any signs of wear and tear that could lead to potential leaks.


Natural disasters like floods are another common cause of water damage on wood floors. When excess water enters your home because of heavy rainfall or overflowing rivers, it has nowhere else to go but into your flooring. This not only causes immediate damage but also creates a breeding ground for mold growth if not dried.

Roof Leaks

A roof that has been damaged by storms or has not been properly maintained can lead to water leaking into your home, including onto your wood floors. Over time, this can cause significant damage and may require costly repairs. It is important to inspect your roof for any signs of damage and address any issues.

Humidity and Moisture

Even without a specific event or accident, excessive humidity levels in the home can cause moisture buildup on wood floors. This can lead to warping, cupping, and other forms of damage. To prevent this, it is important to control the humidity levels in your home through proper ventilation and the use of dehumidifiers.


While we love our furry friends, their accidents and spills can also contribute to water damage on wood floors. Whether it be from a tipped-over water bowl or an accident on the floor, pet urine can seep into the wood causing discoloration and odor if not cleaned up immediately.

Tools and Materials Needed for Repair

When it comes to repairing water damaged house floors, having the right tools and materials can make all the difference. This section will discuss the essential tools and materials needed for a successful repair.

Protective Gear

Before starting any repair work, it is important to prioritize safety. Make sure you have proper protective gear such as gloves, goggles, and a dust mask to protect yourself from harmful chemicals or debris.

Drying Equipment

The steps in repairing water damaged wood floors are by drying out flooring. For this task, you will need a high-powered fan or dehumidifier to help speed up the drying process. You may also want to use a wet/dry vacuum to remove excess water from the surface of the floor.

Pry Bar/Crowbar

To access the damaged areas of your wood floor, you will need a pry bar or crowbar to remove baseboards and trim pieces that are covering them. These tools will allow you to lift and remove these finishing pieces without causing further damage.


In some cases, water damage can cause boards on your wood floor to become loose or detached. To fix this issue, you will need a hammer and nails to reattach them securely into place.

Circular Saw/Jigsaw

If there are severely damaged sections of your wood floor that need replacing, you may need a circular saw or jigsaw to cut out these sections cleanly and precisely.

Wood Filler 

After cutting out damaged sections, you will need to fill in the gaps with wood filler. This material is used to fill in cracks and holes, creating a smooth and even surface.


To prepare your wood floor for refinishing, you will need sandpaper or a sander to smooth out any rough areas or imperfections. This step will help ensure that your repaired floor blends seamlessly with the rest of the flooring.


Once your repairs are complete, you may need to stain or paint the affected area to match the rest of your flooring. Make sure to choose a color that matches closely for a seamless finish.

Finishing Products

To protect and seal your repaired wood floors, you will need finishing products such as polyurethane or wax. These products will provide a protective layer and give your floors a polished look.

Cleaning Supplies

Lastly, make sure to have some cleaning supplies on hand, such as a mop and bucket, to clean up dust and debris after completing the repair work.

Step-by-Step Guide to Repairing Water Damaged Wood Floors

Water damaged wood floors can be a nightmare for homeowners, but with the right steps, they can be repaired and restored to their former glory. Here is the step-by-step guide:

Evaluate the Damage

In restoring water damaged floors you need to evaluate the extent of the damage. Take note of any areas that are heavily damaged and may require replacement. By carefully evaluating the damage, you can create a plan for effective repairs and prevent further damage to your wood floors.

If the damage is minor and limited to a small area, you may be able to fix it yourself. However, if the damage is widespread or severe, it may be best to call a professional.

Remove Excess Water

Before you start any repairs on your wood floor, it’s important to remove any excess water from the affected area. You can use towels or a wet/dry vacuum to soak up as much water as possible. By removing excess water promptly, you can prevent warping, mold growth, and other costly repairs.

Dry Thoroughly

To dry the wood floors, start by opening windows and using fans to increase air circulation. You can also use a dehumidifier to remove excess moisture from the air.

Once the area is well-ventilated, use a dry cloth to blot up any remaining water on the surface. This will prevent further damage and also help in accurately assessing the extent of the damage.

Sand Down Damaged Areas

In cases where there is discoloration or warping of the wood due to water damage, sanding down these areas can help restore them to their original state. Use fine-grit sandpaper and work in a circular motion until you achieve a smooth finish. Sanding down damaged areas not only removes any visual imperfections, but also helps to level out the surface for a more uniform finish.

Replace Severely Damaged Boards

If it has severely damaged some of your wood flooring beyond repair, you may need to replace those specific boards. Carefully remove them using a pry bar and replace them with new ones that match your existing flooring. Finally, sand and refinish the new boards to match the rest of the floor for a seamless repair.

Apply Wood Filler

For smaller cracks or gaps caused by water damage, filling them with wood filler can help restore the appearance of your wood floor. Apply the filler with a putty knife and smooth it out to match the surface of the floor. This will help restore the damaged wood and give your floors a polished look once again.

Sand and Refinish

Once all repairs have been made, sanding down the entire floor and refinishing it will help blend in any repaired areas with the rest of your flooring. Make sure to use a sealant or stain that matches your existing flooring. With these steps, your water damaged wood floors will be as good as new.

Call a Professional

If you’re unsure about how to repair water damaged wood floors or if the damage is extensive, call water damage repair services. They have the expertise and tools needed to assess and repair any damage.

Following these steps will help your water damage repair effectively. Remember to act quickly when you notice any water damage on your wood floors as prompt action can save you from costly repairs in the long run.

Preparation and Safety Measures

When it comes to repairing damaged wood floors, preparation and safety measures are crucial for a successful and safe restoration process. In this section, we will discuss the steps to take before beginning the repair process and important safety precautions to keep in mind. Identify the source of water damage

  • Assess the extent of the damage
  • Remove furniture and items from the affected area
  • Clean up excess water
  • Allow proper ventilation
  • Wear protective gear
  • Turn off electricity
  • Use caution when removing damaged flooring
  • Use proper equipment

Preventing Future Damage

Wood floors are a beautiful and timeless addition to any home. However, they require regular maintenance to ensure their longevity and beauty.

Water damage is one of the most common issues that wood floors face, and if not addressed promptly, it can cause significant damage. In this section, we will guide you in preventing mold growth with some helpful tips for maintaining your wood floors to prevent water damage.

Clean Spills Immediately

The first and most crucial tip for maintaining your wood floors is to clean up any spills immediately. Wood is a porous material that absorbs liquids quickly, making it vulnerable to water damage.

If left unattended, even small spills can penetrate the floorboards, causing warping or staining. Use a dry cloth or paper towel to soak up the spill as soon as possible before it seeps into the wood.

Use Mats and Rugs

One way to prevent water from reaching your wood floors is by using mats and rugs in high-traffic areas such as entryways or near sinks. These areas are more prone to spills and moisture, so having a mat or rug can act as an additional barrier against water damage.

Regularly Check for Leaks

Leaking pipes or appliances can cause significant water damage if left undetected on wood floors. It’s essential to regularly check for leaks in your home, especially in areas where there are exposed pipes such as basements or under sinks.

Avoid Using Excess Water When Cleaning

When cleaning your wood floors, avoid using excess water. Too much water can seep into the wood and cause damage. Instead, use a damp mop or towel to clean your floors. Always wring out the mop or towel thoroughly before using it on your wood floors.

Use Quality Cleaning Products

Using the right cleaning products is crucial for maintaining your wood floors. Avoid using harsh chemicals or abrasive cleaners that can strip off the protective finish and damage the wood. Instead, opt for gentle, pH-neutral cleaners specifically designed for wooden surfaces.

Refinish When Necessary

Over time, the protective finish on your wood floors will wear down and leave them vulnerable to water damage. It’s essential to refinish your floors every few years to maintain their protective barrier. Signs that it’s time for refinishing include scratches, discoloration, and dullness.

Control Humidity Levels

Excessive humidity can also cause damage to your wood floors by causing them to expand and contract, leading to warping and buckling. Invest in a humidifier or dehumidifier if you live in an area with high humidity levels.

Follow These Tips on How to Repair Water Damaged Wood Floors

Knowing how to repair water damaged wood floors may seem like a huge task, but with the right tools and techniques, it can be manageable and cost-effective. Remember to always assess the damage, dry the area thoroughly, and use appropriate materials for the job.

Don’t hesitate to call a professional for help if needed. Follow these steps and restore your wood floors to their former beauty. Take action and start repairing those damaged floors today!
