How to Fix Sagging Hardwood Floors

But never fear – with some essential tools and techniques on how to fix sagging hardwood floors, you can fix sagging floors and restore their beautiful finish without needing to hire a professional. In this post, I’ll outline the leading causes of sagging hardwoods and walk through simple steps you can take this weekend to lift and level your floors once more.

Necessary Items

Before attempting to repair your sagging hardwood floors, gather the following tools and materials:

  1. A large hammer or rubber mallet
  2. Finishing nails
  3. Drill with screwdriver attachment
  4. Carpenter’s level
  5. Wood shims or felt spacers
  6. Hardwood floor adhesive

Ensure you have all these items on hand before beginning the repair process. You may also want a broom and dustpan ready to clean up any debris that falls during the repair.

Identifying the Cause

The first step in fixing sagging hardwood floors is identifying what’s causing the issue. Generally, there are three main reasons for sagging floors:

1. Moisture Damage

If your hardwood floors are sagging in areas with a high moisture level, such as near windows or doors, water damage has likely caused the boards to warp and bend. This can happen if the floor needs to be sealed correctly or if there are leaks present in the room. To fix this issue, you must address any water leaks and replace the damaged boards.

2. Structural Issues

In some cases, the sagging of hardwood floors can be attributed to structural issues within the home. This could include problems with joists or beams that support the floor, which may have weakened or shifted over time. If this is the case, it’s best to consult a professional to repair the structural issue before fixing the floors.

3. Loose Floorboards

The most common reason for sagging hardwood floors is loose floorboards. Over time, boards can become worn and shift, causing dips and uneven spaces. This can be easily fixed by securing the flexible boards in place with finishing nails or screws.

10 Steps on How to Fix Sagging Hardwood Floors

Step 1: Clear the Affected Area

Begin by removing any furniture or area rugs from the affected area. This will give you more room to work and prevent damage to your belongings. Sweep or vacuum the area to remove any debris.

Step 2: Identify Loose Floorboards

Using a carpenter’s level, check each floorboard in the affected area for dips and uneven spaces. Mark any loose boards with a pencil so you know where to focus your repair efforts.

Step 3: Secure Loose Boards

Using your hammer or rubber mallet, gently tap the finishing nails into the loose boards to secure them in place. If the boards are mainly worn, you may need to use screws instead of nails for a stronger hold.

Step 4: Check for Gaps

After securing the loose boards, check for any gaps between the boards where they meet. These can be filled with wood shims or felt spacers to prevent future movement.

Step 5: Apply Adhesive

If there are still areas where the boards are sagging, apply a small amount of hardwood floor adhesive to the underside of the boards. Use clamps or heavy objects to hold the boards in place until the adhesive dries completely.

Step 6: Repeat for Other Loose Boards

Continue checking and securing any other loose boards in the affected area until all are secure and level.

Step 7: Check for Overall Level

Check the entire repaired area using your carpenter’s level to ensure it is now level. If there are still dips or uneven spaces, repeat steps 3-6 as needed.

Step 8: Sand and Refinish

If necessary, sand down any uneven areas or apply a new finish coat to the repaired section. This will give your floors a uniform appearance and help them blend with the rest of the room.

Step 9: Replace Damaged Boards

If moisture damage is the cause of your sagging hardwood floors, you may need to replace the damaged boards completely. Use a circular saw to cut out the damaged section and replace it with a new board of the same size. Secure in place with finishing nails or screws.

Step 10: Prevent Future Sagging

To prevent sagging hardwood floors in the future, regularly inspect and secure any loose boards. Also, be mindful of moisture levels in your home and address any leaks immediately to avoid water damage. Consider using protective pads under heavy furniture to prevent excess pressure on the floors.

Fixing sagging hardwood floors can be a manageable task. By identifying the cause and following these simple steps, you can restore your floors to their former glory without breaking the bank. Remember to inspect and maintain your floors regularly to prevent future issues. So, keep these simple tips in mind and make your sagging hardwood floors as good as new again.
