What Causes Buckled Hardwood Floors?

1. Moisture and Swells

One of the most common causes of hardwood floor buckling is excessive moisture. This can be caused by flooding or a slow accumulation of water seeping up from the concrete subfloor. Moisture can cause the wood to expand and swell, pushing out against the boards that contain it and causing them to buckle up.

2. Improper Installation

Another potential cause of buckled hardwood floors is improper installation. Improperly installed floors can cause buckling when the subfloor isn’t level, or when the floor was laid too tightly, not allowing for natural expansion and contraction of the wood. This type of buckling usually happens near walls or corners where there may be more movement in the floorboard due to its tighter fit.

3. Heat and Humidity

Finally, buckling can be caused by large swings in heat or humidity. When temperatures rise, wood expands; when they drop again, it contracts. If the boards were installed too tightly, this expansion and contraction can cause them to buckle up as well.

Fortunately, there are a few ways to repair buckled hardwood floors and get your floors looking like new again. Keep reading to find out how you can fix buckled hardwood floors and what steps you should take to prevent them from happening in the future.

How to Repair Buckled Hardwood Floors in 6 Easy Steps

Step 1: Remove All Furniture and Other Items From the Room

The very first step is to remove all furniture and other items from the room. This includes any rugs or floor mats that may be in place. Also, you have to make sure that all nails, staples and other objects are removed from the floor.

Step 2: Prepare the Floor

Once you have cleared the room of furniture and objects, you can begin to prepare the floor for repair. Start by removing any loose boards from the area with buckling. If needed, use a crowbar or flat pry bar to help remove them. After the loose floorboards have been removed, use a hammer and chisel to level out any raised portions of the floor.

Step 3: Nail Down Buckled Areas

Once the area is prepped and ready for repair, start by nailing down the buckled areas with finishing nails. Make sure that you drive in the nails at an angle so they will hold firmly. If you have the right tools, you can also use a pneumatic flooring nailer for this job.

Step 4: Check the Subfloor

Before going further with your repair job, inspect the subfloor underneath for any signs of water damage or rot. If needed, replace any damaged pieces and make sure to fill in any holes with wood putty or wood filler.

Step 5: Apply Floor Leveler

Once the subfloor has been inspected and repaired, you can apply a self-leveling compound to the buckled areas of the floor. This will help fill in any gaps and create an even surface for your hardwood floors. After the leveler is applied, give it time to dry completely before moving on to the next step. After the leveler has dried, sand down any high spots and fill in any low spots with wood putty or filler.

Step 6: Refinish Your Hardwood Floor

Once all of the repairs are complete, you can apply a fresh coat of finish to your hardwood floor. This will help protect the surface from further damage and give it a beautiful new shine. For the best results, make sure to use a high-quality finish that is designed specifically for hardwood floors.

Following these steps will help you successfully repair your buckled hardwood floors and get them looking like new again. Just be sure to take the time and patience necessary for this type of job so that it’s done properly.

Some Extra Tips to Repair Buckled Hardwood Floors

1. Use a Moisture Meter

This is the most important tool for fixing buckled wood floors. A moisture meter can help you identify any areas that may be too wet or dry, which is often the cause of buckling and warping.

Also, ensure that any exposed areas of your floor have a relative humidity level between 30 and 50%.

2. Fill the Gap with Resin

If there is a gap between the boards, fill it with a resin filler. This will make sure that moisture cannot seep through and cause more buckling and warping in the future. Also, make sure to sand the area smoothly with a belt sander before applying the resin.

3. Use Wood Screws

For large cracks or gaping holes, use wood screws to hold the boards together and help prevent future buckling. Make sure to use a drill bit that is slightly larger than the screw so that it can go through both pieces of wood without splitting them apart. Also, predrill the holes and countersink the screws to ensure a smooth finish.

4. Remove Excess Moisture

If the wood flooring is exposed to moisture due to flooding or plumbing leaks, it’s important to try and remove as much of the water as possible. Use a wet/dry vacuum and mop up any standing water. Use fans to help the area dry quickly and then seal the wood with a waterproof sealer.

5. Call in Professionals

If you’re unable to repair the buckling hardwood floors yourself, it’s best to call in professionals who specialize in flooring repairs. They can properly assess the situation and take the necessary steps to restore your floor to its original condition. Have them fix the buckling and take measures to prevent it from happening again in the future.

By following these steps, you’ll be able to repair your buckled hardwood floors without too much hassle. Just make sure that you use the right tools and take all necessary precautions when dealing with moisture or gaps in between the boards.
