Is it worth investing in professional installation of a composite decking terrace?

What is a terrace made of composite decking boards?

Composite decking boards are made by combining wood and plastic. This means they bring together the natural appearance of wood and the strength and moisture resistance typical of synthetic materials.

The main advantages of composite decking boards:

• Resistance to moisture and mould.
• No need for impregnation.
• Easy to keep clean.
• Long lifespan.
• Attractive appearance.

Thanks to these properties, composite is increasingly being chosen instead of traditional wooden boards. But is it worth commissioning professionals to install it?

How much does professional installation of a terrace made of composite decking boards cost?

The installation cost depends on many factors, such as:

• Terrace area – The larger it is, the higher the installation cost.
• Type of base – If additional ground preparation is needed, costs will increase.
• Installation system – Some systems require special substructures, which increases labour costs.

Average prices for installing a composite terrace in 2024:

• Materials (decking boards, joists, substructure): from 200 to 500 zł/m²
• Professional installation: from 100 to 250 zł/m²

Professional installation vs DIY installation.

Many people choose to lay their terrace themselves in order to save money. However, not everyone is aware of the challenges involved.

Advantages of professional installation.

• Quality assurance – Professionals have the experience and knowledge to lay the boards correctly and prevent them from warping or cracking.
• Proper ventilation and a stable structure – Installation mistakes can lead to moisture problems, shortening the terrace's lifespan. Professionals know how to prepare the base and drainage system properly.
• Saving time and hassle – Building a terrace involves more than just laying boards: it also requires proper preparation of the base, levelling and securing the whole structure. Professionals will do this more quickly and without the stress.
• Safety – A poorly installed terrace can be dangerous for users. Professional installation eliminates the risk of instability and unevenness.

Disadvantages of professional installation.

• Higher cost – Of course, hiring a team involves additional costs, which can amount to as much as several dozen per cent of the value of the materials themselves.
• The need to find reliable professionals – Not every building team is experienced in installing composite decking boards, so it is worth checking reviews and references before choosing a contractor.

The most common mistakes when installing a terrace yourself.

If you decide to install it yourself, look out for the most common mistakes, which can lead to costly remedial work:

• Incorrect preparation of the base – A lack of adequate drainage can cause water to accumulate and damage the boards.
• Incorrect gaps between boards – Composite expands when temperatures change, so suitable expansion gaps must be maintained.
• Incorrect installation of joists – If they are laid incorrectly, the whole structure may become unstable.
• Using the wrong screws and connectors – Using unsuitable fixings can weaken the terrace structure.

When is professional installation worth choosing?

If durability and appearance matter to you, professional installation is an excellent investment. It is particularly worth considering if:

• You have no experience in construction work.
• You want to avoid costly mistakes.
• Durability and safety are important to you.
• Your terrace has an unusual shape or requires special preparation of the base.
