How to Maintain Composite Fencing?

Many people are opting for composite fencing these days. It looks like wood and works better than plastic. It doesn’t take much labour to care for a composite fence. Use warm soapy water and a soft-bristle brush to clean it once a year or every other year to get rid of dirt, pollen, and mildew. Don’t use powerful chemical cleaners because they can hurt things.

Also, trim plants regularly to keep mildew from building up. Be careful when using low-pressure washers. This article lists the most important things to do to keep composite fencing in good shape. You can easily address several issues to keep your fence looking new.

What is a Composite Fence?

You should know what a composite fence is before you start taking care of it. Most of the time, composite fencing is made up of the following parts:

Wood Fibres: Give the look and feel of real wood. Most of the time, this element is made from wood items that have been recycled, including shavings and sawdust.
Recycled plastic: This is plastic that has been used before, such as milk bottles, plastic bags, and other things. The material is really good at keeping water out and not rotting because it has plastic in it.

This special mix of materials has benefits that standard wood can’t match:

Resistance to moisture and corrosion: The surface of the composite fence keeps water from getting through, which stops mould and wood rot from growing.
Dimensional Stability: Unlike wood, which swells when it gets wet and cracks and warps when it dries out, composite fence does not.
Insect Resistance: Composite fencing doesn’t attract wood-eating bugs like termites.

Daily Maintenance of Composite Fencing

With composite fencing, you don’t have to do things like sanding, staining, and sealing anymore. That doesn’t mean it doesn’t need to be taken care of, though. Your fence will seem brand new and robust for decades to come if you check it and take care of it regularly.

Cleaning Regularly

It’s important to do simple, regular cleaning. It’s easy and quick to clean composite fencing. Most of the time, mild soapy water and a soft-bristled brush will get rid of most of the filth. You can use specialised methods to get rid of tough stains.

Getting Rid of Mould and Mildew

Fences are most likely to be damaged by mould and mildew, especially in wet, shady places. How to treat:

Pre-treatment: Before you start, be sure to clean the fence and the area surrounding it well by getting rid of all the leaves and other organic debris you can see.
Selecting a Cleaner: Mix two parts white vinegar with one part water, spray it on the mouldy spots, and let it sit for 10 to 15 minutes.
Scrubbing and Rinsing: Use a soft-bristled brush that has been dipped in the cleanser to scrub the wood grain. Finally, give it a good wash with clean water.

How to Fix Scratches and Wear

Even though composite fences are strong, sharp instruments can nevertheless leave marks. How to Treat:

Natural Fading: Small scratches may fade away on their own after a few months, blending in with the colour around them.
WD-40: To make the scratch less visible, spray WD-40 on a soft cloth and clean the area over and over.
Heat Gun: Set the heat gun to about 450°C (832°F). Keep the nozzle 10 to 15 cm (4 to 6 inches) away from the surface and brush it evenly over the scratch. The heat will make the material a little bit softer, which will smooth out the mark.
Sandpaper Sanding: Use 60–80 grit coarse sandpaper to carefully sand the area along the wood grain to get rid of deeper marks. Don’t push too hard if you don’t want indentations or uneven colouring.

Other Ways to Get Rid of Stains

Some common ways to get rid of stains are:

Grease: Use a soft cloth that has been soaked with mild soapy water to wipe it off. You can use an all-purpose cleaner on the residue.
Salt and Calcium Chloride: If calcium chloride or winter de-icing salt gets on the fence, wash it off right away with clean water and a soft brush.
Chalk Marks: You can get rid of kids’ chalk drawings using water and a soft brush.
Spray Paint: If you accidentally get spray paint on yourself, make sure you use the proper solvent for the kind of paint. First, try the liquid in a place where it can’t be seen to make sure it doesn’t hurt the surface of the composite fence.

Maintenance of Composite Fences in Different Seasons

In addition to routine cleaning and maintenance, you also need to undertake certain checks and maintenance during each season.

Spring Maintenance

Spring is the greatest time to check and clean your fence after the rain, snow, wind, and frost of winter.

Check Structural Stability: Make sure that each post stays in place and doesn’t lean or fall. Look for screws that are missing or loose on all the connections between the beams and panels.
Damage Assessment: Check the wooden planks for cracks, bends, or breaks that could have happened because of freezing weather or hard strikes. Parts that are close to the ground are more likely to get damaged by water, so pay additional care to them.
Debris Removal: Get rid of the dead branches, leaves, and dirt that built up at the base of the fence and in its cracks during the winter. This makes sure that the bottom has good airflow and drains efficiently.
Trim Vegetation: Cut back any plants, shrubs, or vines that are touching the fence. Keep a space of at least 15 to 30 cm. This stops plants from holding onto moisture, which encourages mould formation.
Deep Clean: Use a broom or soft brush to sweep away loose dust, pollen, and cobwebs from the fence. Use soapy water and a soft-bristled brush to wash the whole fence well.

Summer Maintenance

Summer is a time when plants develop quickly, so care is mostly about keeping everything clean and avoiding scratches.

Vegetation Management: Plants grow quickly in the summer, so you need to examine and trim them more often. Don’t let the vines wrap over the fence. When water and shadow get stuck, the chance of mould growing increases a lot.
Stain Removal: Summer activities like barbecues and parties on the terrace become more common. Take care of food, grease, or dirt spills on the fence right away.
Caution with Heat Sources: Never install grills, fire pits, or other hot things immediately next to a composite fence. Leave at least one metre of space for safety.

Fall Maintenance

Get ready for winter by doing a thorough cleaning in the fall.

Thorough Sweeping: The hardest part is getting rid of the leaves that have fallen. They build up at the bottom and in the spaces between panels, where they decay and encourage mould growth. Use a brush or leaf blower to clean up leaves and other trash around the fence and on the fence itself.
Deep Cleaning: Give everything a good wash at the end of the season. Get rid of pollen, dirt, and any mould that may have grown over the spring and summer.
Check and Secure: Go over all the hardware again and make sure it’s tight. In the fall, the wind might loosen screws. If you tighten them ahead of time, winter storms won’t be able to inflict as much damage.

Winter Maintenance

The cold weather, snow, and ice of winter are quite hard on the structure of fences.

Check Drainage: Make sure that the area surrounding the posts is clear for drainage. Check the bases of the fence to make sure there are no puddles.
Snow Management: When you clear snow from your patio, never put it against the fence. Snow can bend fence panels or shatter joints because of how heavy it is.
Use a Plastic Shovel: If you need to clear snow off the fence, always use a plastic shovel. Don’t let metal shovels harm your stuff.

Conclusion

Composite fences free us from annoying maintenance responsibilities because they work so well. You can keep your composite fence robust and looking beautiful for a long time by following the maintenance and checks listed above.

FAQ

How Long Does Composite Fence Last?

With the right placement and minimal care, a decent composite fence should last between 25 and 30 years. It will survive a lot longer than the 15 years that wood fences usually last. It will last a long time because it won’t rot and can handle the weather.

Is it okay to use bleach to clean my composite fence?

Not a good idea. Bleach is a strong oxidising chemical that can eat away at the surface of a composite fence, rendering it brittle, discoloured, and chalky. Instead, choose milder, more targeted cleaners or a solution of white vinegar.

How can I safely get rid of ice and snow on my fence in the winter?

Do not hit ice with metal tools, as this can scrape or even break the boards. Letting things melt naturally is the safest way to go. Use a plastic shovel to clear snow if you need to step in. Also, make sure that the bottom of the fence drains well so that it doesn’t freeze.
