Verandah Decking

Mistakes to Avoid When Building a Veranda Deck

A verandah deck is a composite deck material with reversible finish – one side features a wood grain finish and the other side features a combed finish. A verandah deck can be used to build any kind of deck and gazebo or patio. A verandah deck usually lightens during the initial 2 to 3 months after building due to sunlight exposure as it is mainly used for outdoors. After 2 to 3 months, there will be no further color fading and lightening. When planning on building a new verandah deck, avoid making the mistakes listed below.

1. Using Board Lengths That Are Too Short or a Poor Layout

When you use board lengths that has a poor layout or boards that are too short, it can cause wastage of the deck boards. Insufficient planning can result in spending more and going over your budget. It also delays the time that is needed to build your deck. Think carefully before planning on this project to avoid these kinds of problem.

2. Under-Estimating the Board Quantity and the Time Needed for Installation

A normal deck project usually goes beyond the budget when there is poor planning and poor decision making. Wastages caused by odd-shaped decks, triangles, circles, 45-degree angle or non-squared deck shapes can increase the quantity of boards required and time involved significantly. To avoid or solve this problem, you have to design your verandah in such a way that it suits the deck boards’ length. This will reduce board wastage, and you will get an even bigger deck without additional cost. This will also make installation fast.

3. Painting the Verandah Deck

Remember that only the top of the deck can be painted. This means that the boards’ other three sides are not painted. When moisture gets into the deck, it causes the deck to swell which makes the paint crack and peel. Water seeps in after the paint cracks and causes rotting.

4. Building Decks That Are Too High

Building consent and a handrail are required when you are planning to build a verandah that is over 3 feet/1 meter high. This process is usually time consuming and costly. If you do not get the needed consent, it can cause a problem later on if you want to sell the house.

5. Building a Poorly Ventilated Verandah Deck

Verandah decks need ventilation. The substructure needs airflow to prevent it from swelling, rusting and rotting. Therefore, moisture exposure especially during winter has to be reduced. Allow a 12mm gap allowance from another building structure (such as retaining wall or house) when building a verandah. This will allow water to drain and prevent capillary action. The boards must not be in contact with another surface or the ground, with the substructure as an exception. If the decks are very close to the ground, ventilation grates can be used to allow air flow.
