No More Annoying Creaks: How to Fix Gaps Between Your Wood Floor Boards

Have you ever walked across your wood floor and heard an annoying creak or noticed unsightly gaps between the boards? These issues can not only be frustrating but can also be a potential hazard. If left untreated, the gaps between the boards can cause tripping hazards and may even damage the subfloor. Fortunately, fixing these gaps and creaks is easier than you might think. In this article, we’ll walk you through the steps to fix gaps between your wood floorboards and eliminate those annoying creaks once and for all. From identifying the cause of the problem to choosing the right materials and tools, we have you covered. So, let’s dive in and learn how to get your wood floors looking and sounding their best.

Reasons why wood floor boards develop gaps

Wood floorboards develop gaps for several reasons. One of the most common reasons is humidity and temperature fluctuations. When the weather changes, the wood floorboards expand or contract, causing gaps to appear. Another reason for gaps is improper installation. If the installer did not leave enough space between the boards during installation, gaps may appear. Additionally, as the wood dries out over time, gaps may develop.

It’s important to note that wood floor boards may not develop gaps immediately after installation. Sometimes, it may take a few months or even years for cracks to appear. Therefore, it’s essential to keep an eye on your wood floors and address any gaps as soon as you notice them.

Consequences of Gaps in wood floorboards

Gaps in wood floorboards can lead to several consequences. Firstly, they can be a tripping hazard. If you have pets or young children, gaps can pose a significant risk to their safety. Additionally, gaps can collect dirt, debris, and even liquids, making them challenging to clean. Over time, this debris can cause the gaps to widen, leading to further damage. Lastly, gaps can lead to drafts, reducing the effectiveness of your home’s heating and cooling systems and increasing your energy bills.

How to prevent gaps in wood floorboards

Preventing gaps in wood floorboards is much easier than fixing them. Here are some tips to prevent gaps from forming in the first place:

– Keep humidity and temperature levels consistent: Fluctuations in humidity and temperature can cause the wood to expand and contract, leading to gaps. Therefore, it’s essential to keep your home’s humidity levels between 35% and 55% and temperature levels between 60°F and 80°F.

– Use a humidifier or dehumidifier: If you live in a particularly dry or humid area, consider using a humidifier or dehumidifier to maintain consistent humidity levels.

– Choose the right wood: Some woods are less prone to gaps than others. For example, maple and oak are less likely to develop gaps than softer woods like pine or fir.

– Proper installation: Ensure that your wood floor is installed correctly by a professional. They can ensure that the boards are properly spaced apart, allowing room for expansion and contraction.

By following these tips, you can significantly reduce the likelihood of gaps forming in your wood floorboards.

How to fix gaps in wood floorboards

If you already have gaps in your wood floor boards, there are several ways to fix them. The method you choose will depend on the size and severity of the gaps. Here are a few options:

– Wood filler: If the gaps are relatively small, you can use a wood filler to fill them in. Wood filler is a putty-like substance that you can apply to the gaps and then sand down once it dries.

– Rope: For slightly larger gaps, you can use a rope to fill them in. Cut the rope to the length of the gap, and then push it into the gap using a putty knife. Once the rope is in place, sand it down to create a smooth surface.

– New boards: If the gaps are severe, you may need to replace the affected boards entirely.

Tools needed for fixing gaps in wood floorboards

Fixing gaps in wood floorboards requires a few tools. Here are the tools you’ll need:

– Putty knife

– Sandpaper

– Wood filler or rope

– Circular saw (if you need to replace boards)

– Hammer and nails (if you need to replace boards)

Steps to fix gaps in wood floorboards

Now that you have your tools ready, here are the steps to fix gaps in your wood floorboards:

1. Clean the gaps: Before you begin filling in the gaps, it’s essential to clean them out thoroughly. Use a vacuum or a small brush to remove any debris or dirt in the gaps.

2. Choose your method: Decide on the method you will use to fill in the gaps. Will you use wood filler, and rope, or replace the boards entirely?

3. Apply the filler: If you’re using wood filler, apply it to the gaps using a putty knife. Make sure to fill in the gaps entirely and remove any excess filler.

4. Sand down the filler: Once the filler is dry, use sandpaper to sand down the surface until it’s smooth and even.

5. Replace boards: If you need to replace the affected boards, use a circular saw to cut them out. Then, use a hammer and nails to secure the new boards in place.

6. Sand down the surface: Once the boards are in place, use sandpaper to sand down the surface until it’s smooth and even.

Tips for maintaining wood floorboards

Maintaining your wood floorboards can help prevent gaps from forming in the first place. Here are some tips to maintain your wood floors:

– Sweep or vacuum regularly: Regular sweeping or vacuuming can help prevent dirt and debris from collecting in the gaps.

– Use mats or rugs: Placing mats or rugs in high-traffic areas can help reduce wear and tear on your wood floors.

– Refinish your floors: Over time, your wood floors may become damaged or worn. Refinishing them can help restore them to their original condition and prevent gaps from forming.

When to seek professional help for fixing gaps in wood floorboards

While fixing gaps in wood floorboards is a relatively simple process, there may be situations where you need to seek professional help. For example, if the gaps are widespread or severe, it may be best to hire a professional to replace the affected boards. Additionally, if you’re not comfortable using power tools or handling wood filler, it may be best to hire a professional.


Gaps in wood floorboards can be frustrating, but they’re also relatively easy to fix. By following the steps outlined above, you can eliminate those annoying creaks and gaps and get your wood floors looking and sounding their best.
