The best way to fix a water-damaged floor is to nail the planks together or replace them one by one. It all depends on the sort of floor you have and how much water damage it has sustained.

Keep an eye on the moisture content of your floor material, as wood floors tend to buckle or swell when they are saturated. To repair damaged hardwood, simply use new nails, but laminated wood will need to be completely replaced.

Signs Of Water Damage

Leaking pipes and appliances, bad weather, and floods are just a few of the things that can lead to water damage in the home. Before it’s too late, stay on the lookout for any signs of water damage.

Hardwood floors

Pure wood is used in the construction of these flooring, which are typically manufactured from oak or hickory trees. As a result of its strength and durability, this type of flooring is frequently used as a floor covering.

Because hardwood cannot be damaged by water, it is not a good choice for flooring. Wear and tear can occur when it’s soaked for an extended period of time.

If you notice any of the following:

  • Mold colonies are visible in the form of dark patches.
  • When the floorboards swell, this is known as “bulging.”
  • After a while, you will notice that the edges of your floor are not even.
  • When the planks are completely removed from the subfloor, buckling occurs.

Laminate floors

The wood used to construct these flooring is a variety of species that have been glued together. In addition to being scratch-resistant, easy to clean, and reasonably priced, laminate floors are great for the home.

Because of its susceptibility to water damage, this material is not recommended for use in bathrooms or kitchens. Even in the most secure parts of your house, it is possible that your laminate floors will become excessively wet. Laminate floors might show evidence of water damage.

  • Planks bulge or “cup” when moist, a phenomenon known as warping.
  • Discoloration — If your planks have dark areas, it could be a sign of mold or mildew.
  • It is common for the plank edges to have swelling damage.

Step-By-Step Process On How To Repair Water Damaged Floor

As soon as you notice your floorboards expanding, it’s time to fix them. Repairing hardwood and laminate wood requires different methods.

Method #1. Flattening hardwood floors

Wooden structures are more durable, therefore they may just require a small repair.

Step #1. Fix the small warped areas

You can nail or screw the bulging planks flat on the floor again.

Step #2. Remove severely damaged areas

Nail or screw the planks back down to the floor so they don’t sag.

Step #3. Sand the boards

Now that you’ve sanded your floor to make it look even, you may enjoy your once-perfect floor once more!

Method #2. Flattening laminate wood floors

As a result of laminate floors’ greater ability to absorb moisture, more substantial repairs are required.

Step #1. Dry the floor

Using a dehumidifier or a few fans will cause your floor to sag.

Step #2. Remove damaged boards

Work your way outward from the wall’s planks. Remove any and all damaged planks, or even the entire floor, if needed.

Step #3. Replace the damaged planks

It is possible to re-purpose some of the boards. Subfloor must be entirely dry before new boards may be installed.

Should You Also Repair The Subfloor?

Plywood or concrete are common materials for the subfloor, which sits beneath your main floor. Your boards may raise and swell with moisture because of this damaged area, and it may feel mushy when you tread on it.

Before replacing the main planks, you must first repair the subfloor. To replace the damaged plywood, first use a circular saw to remove the old flooring. You need to make sure this layer is in top shape to keep the boards from buckling up.

How To Prevent Swelling In Wooden Floors

Repairing a flattened floor can be expensive, especially if the damage is extensive. That’s why it’s important to protect your planks from water damage in order to save money.

Place rugs on the floor

Rugs can shield your planks from dribs and drabs of water, such as sprinkles. Dishwashers, washing machines, and refrigerators all use water, thus this should be done in the vicinity of them.

Make the boards water-resistant

Coatings and waxes can help preserve your floors from wear and tear. Apply a coating or sealer to the boards before they are put, but remember to reapply the chemical every year.

Spreading wax evenly on the floor is another option. Your boards should be free of any urethane, which could make them overly slippery. Every year, this chemical must be applied.

Will Home Insurance Cover Floor Buckling?

If your floor has been severely damaged by water, you may need to replace it. The cost of repairs is going to be very significant in this case.

That’s an option, isn’t it? Is it going to pay for the damages and the costs of repairs?

There are several variables to consider when it comes to determining the extent of water damage. Leaks and defective appliances are covered by most insurance policies. If you’re lucky, sewage overflow may also be covered.

Another problem is flooding caused by bad weather. Flood insurance is required for most people to cover these issues. Don’t forget to negotiate with your agency, and if you have any questions, call your lawyer!

Water Damaged Floor Repair Cost

For water-damaged floors, these are some ballpark figures for the cost of repairs. Repairing floors is more expensive than simply replacing them, as you’ll soon discover. Hardwood, tile, and polished concrete are all examples of surfaces where it may be worth it to have them repaired. Replacement of water-damaged vinyl, laminate, engineered wood, or carpet flooring may be more cost-effective in the long run since synthetic flooring traps moisture beneath it and deteriorates the subfloor and floor joists beneath it.

Hardwood Floor Water Damage Repair Cost

It costs $8 to $30 per square foot to repair water-damaged floors, depending on the complexity of your project and the type of wood you’re utilizing for flooring. It’s more expensive, but if you’re on a tight budget, repairing your hardwood floors may be a better option because it’s less disruptive and can be done over time.

Money-Saving Tips for Fixing Water Damaged Floors

Firstly, restoring water-damaged floors is more expensive per square foot than replacing them. Repairing a floor made of low-cost vinyl or laminate is rarely worth the effort. Even if the water damage is limited to a small section of the floor, it’s still a problem.

Removing the damaged material yourself can save you money when it comes to repairing water-damaged floors. Removal of material accomplishes two goals. This could speed up the evaporation of moisture by increasing the amount of airflow. In addition to the water damage, you should check the subfloor to determine if there is anything else that need immediate attention. The second benefit is that you’ll avoid the cost of hiring a professional to remove the wet flooring.

Avoid damaging the surrounding flooring, subfloor or joists when removing the afflicted flooring if you decide to go this route.

Fixing the floor and replacing what needs to be replaced yourself could save you a lot of money. A professional, on the other hand, will usually perform a better job of blending the repaired area into the surrounding environment. For both visual (color) and functional (fit and preventing gaps and fractures) integration, this is true. If you’re going to have the service done by a professional, make sure you acquire a quote for the cost of floor repair so you can shop around.
