Hidden fasteners are replacements for screws when you want to install composite decking. Aside from making the top of your decking attractive, they will securely hold down the composite boards. Homeowners prefer hidden fasteners to screws and nails because of the beauty that it provides. This makes installing wood-plastic decking worth it. As the best patio material, plastic wood decking offers better durability than timber and plastic altogether. Also, wood-plastic composite is easy to maintain. But failure to maintain your composite decking will eventually lead to damage. This implies that the surface of your wood-plastic decking might sag, or mould can destroy it. When this occurs, you must take steps to repair your composite decking with hidden fasteners.

What Are Hidden Fasteners?

Hidden fasteners are tools you can use to install your plastic wood composite. Unlike the open installation method that requires screws and nails, hidden fasteners are concealed from the surface. They are made of starter clips and intermediate clips. Starter clips are used to start installing the decking, while intermediate clips are used to install the remaining. The starter clip looks like the letter L, while intermediate clips look like the letter T. The T edges of the intermediate clip will hold down composite boards at both sides.

While the little curve on the L top of the starter clip will hold down the boards, using clips to install your composite wood decking makes it attractive. This is because you won’t see the screws on top of your decking boards like when you use screws. Also, your decking is secure and safe to walk on without the nails or screws sticking out of the decking. But when repairing your composite wood decking, it can be difficult to remove the boards. This is because they are held down together by clips that must be removed before the boards can be removed. 

How to Repair Your Composite Decking 

Repairing composite decking in this context means taking steps to regain your decking after you discover it on the surface. Note that how you repair your composite decking differs based on the wear on your decking. But when you want to repair by changing the boards, you must remove the boards by un-clipping them first. If you discover scratches on your wood-plastic decking surface, you only have to clean the top and leave the scratch to fade. 

But if the scratches are too obvious, then you might have to replace the boards. That is one way you can repair your wood-plastic composite. Another reason you might have to repair your plastic wood decking is mould growth on the top of the decking. This means that when you discover mould or mildew on your plastic wood decking, you must scrub it. This repair process does not require replacing or removing the clips; just clean with a gentle scrub. We have explained how you can repair your composite boards if you want to replace or remove the boards.

Step One- Inspect the Composite Decking

Inspecting the decking is the first step to repair your composite decking. This will enable you to identify the spots that need repair. If your composite boards are seriously damaged, then you should contemplate changing the boards. But if you discover little damage on your decking, you might take the step to repair it without replacing the decking. 

Step Two – Fix the Damage

How you fix the damage on your plastic wood decking depends on the kind of damage. For mould growth or oil stain, you should prepare a water solution that contains soap. Then get a good decking brush to scrub the top of the decking. Try to peel off the mould before scrubbing the decking to make it easier. If you discover that your decking sag, you should look for a good screw and unscrew the fasteners. 

This unscrewing task will be a little hard; that is why most homeowners don’t like hidden installation. If your decking boards are not installed properly, then unscrewing them will enable you to rearrange the boards. But if the boards are damaged, then they need replacing. You should do the same if you discover that the surface of your composite decking breaks or splinters due to heat. A splintered decking might need replacing. So, you must unscrew the boards and then change them.


There are several ways you can repair composite decking with hidden fasteners. You can either scrub the surface of the decking or change the damaged boards.
