Nowadays, many people prefer to lay parquet floors in their homes because of their classic look and durability. Hardwood floors can be of different types and make a good impression in any home.

The advantages of a wooden floor include the ease of installation, the ease of cleaning and the ability to integrate with a variety of interior styles.

The only thing you need to do with hardwood floors is to update any holes that may appear over time.

This is something you can only really avoid if your floors are newly installed because they require a lot of maintenance.

If the wood has not been treated before, preventive measures cannot have the same effect.

So why do cracks appear in hardwood floors? When the temperature changes during the day or season, the wood expands and shrinks to react.

You may not notice any cracks in the first few days of installation, but after a few weeks they will start to appear. These holes are perfectly normal and can easily be filled, so don’t panic!

Let’s start with temporary measures…

Fast solution

As with many things in life, there are quick solutions you can choose if your budget doesn’t allow you to find a permanent solution.

These are temporary solutions, and they will not last as long as the longer sentences in this article, but it is useful to underline their existence.

Putty used to be a way to fill the joints of your hardwood floor.

However, many soil layers began to notice the negative effects of the putty, which led them to look for other ways to solve the problem.

They discovered that the putty had hardened over a long period of time and began to crack.

This damages the floor and makes it worse than if there were joints! The solution to this new problem is to dig up all the old hard putty and replace it.

As you can imagine, this is a very long process, so many layers of the game are dedicated to new ways to solve problems.

Again, the use of wood putty is only a temporary measure. Wood filler has a slightly different consistency than putty, which means that even after the filler has dried, your floor will expand and shrink depending on the temperature of your home.

The only way to prevent the movement of the wood filling is to keep your house moist all day long.

It can be very difficult to keep track of everything, especially if you don’t work from home or if you have a fixed budget for air conditioning. If these shortcomings continue to hamper you, it makes sense to look for longer-term measures.

We also advise you to only fill the small joints of your floor with wood filler. Avoid using it over long distances, because they don’t hold up very well!

Long-term solutions

Many people may want to switch from temporary to long-term solutions.

They are much more economical for you and much more durable.

Below we present our four main mounts that can help you fill in the small and large holes in your hardwood floor!

This is an excellent solution for the narrow spaces that are beginning to form in your floor. Instead of pushing the gap filling when your wood expands under the influence of heat, it bends with the floor.

Be sure to vacuum the syringe before use to remove any dirt that may interfere with its operation. The putty works like a tube of putty, so just cut the tube and apply it to each crack. You’ll see the difference right away!

A good option for a larger shaped space is to use pieces of the same wood to fill it. To successfully fill in the holes, cut them to size and apply a little wood glue to the edges. Make sure your room is damp before inserting the wood into the joints, as this gives the best results.

Because the wood expands with moisture, you may need to use light force to force the wood into the crevices. You can do this by gently tapping the pieces of wood with a hammer. Be careful not to use too much force, as this can damage the floors.

One of the oldest tricks in the book is to fill holes in your hardwood floor with pieces of rope. You have to cut them off and slide them into the slots. For best effect, the rope should be at the level of the wooden floor.

You may want to colour the rope according to the colour of your floor. This makes it fit better in your wooden floor instead of sticking out like a sore thumb. The use of the rope as a filler also plays a role in the insulation, which is a great advantage!

Maybe you recently had a hardwood floor laid and the carpenter left sawdust behind. You can use the sawdust to fill in the holes that will arise in the coming days. Please note that this technique is only suitable for newly laid and unfinished floors.

If you decide this is the best solution for you, take sawdust and mix it with polyurethane. This creates a thick paste that can easily be poured into the holes to be filled.

Prevention methods

These prevention methods are suitable for newly installed floors or all restored wooden floors.

The best prevention against cracks in your floor is regular waxing. With what regularity? It depends on the type of wax used.

You can use either liquid wax, which must be reapplied every two years, or hard wax. Hard wax must be reapplied every two to five years.

If you are still unsure how often you need to clean, contact your floor manufacturer for further advice.

Complete exchange

In some cases, the clearances can be much less than with repairs, and the best option would be to replace the entire wood floor. This option should only be considered if the floor covering is damaged, old, warped or has large joints requiring extensive maintenance.

Replacing the floor seems a rather expensive option at first. However, if you sit down and calculate the cost of a repair, it is probably cheaper to get a new floor covering.

If you decide to replace your floor, don’t forget to wax it regularly and fill any gaps with the suggestions in this article!


We hope our suggestions today have raised your hopes. After all, the joints in your floor can be repaired!

A quick solution is possible, but it should only be temporary! They’re cheap, but they don’t last too long. So they can only be adapted if you are looking for a more permanent solution.

When it comes to a permanent solution, you have many possibilities. You just have to do the right thing. Whether it’s rope, sawdust, wood or soft fillers, you won’t be disappointed in your decision.

The care of the floors is very important, but if they are well maintained, you will see their beauty.

As long as you keep this up, you’ll have beautiful floors that everyone will love!
