Frequently Asked Questions

Deck boards are attached to the structure underneath using screws or ironmongery specifically for the decking product you select.

As timber is a natural product, it can move slightly when exposed to the weather. This is why it is recommended that we leave a small gap between deck boards. This is why it is recommended that you leave a small gap between deck boards - anything from 3mm to 10mm will be sufficient. The most commonly used gap size between boards being 5mm.

Deckmasters use composite decking as they are low maintenance. This superior product never needs painting, oiling, or staining.

Composite decking is extremely water resistant and also slip resistant. It is also it ideal for use alongside hot tubs and swimming pools.

Not at all. Due to the versatility of timber decking, a panel can be used to cover the drain and allow simple access when required.

As a matter of course we cover any vegetation areas with a weed and plant suppressing membrane preventing future growth.

Regularised 100 x 50mm preservative treated joists and beams form the support carcase to which the deck boards are screw fixed. These are Use Class 3 (UC3 suitable for out of ground contact). The beams of the carcase are connected to 75 x 75mm Use Class 4 (UC4 suitable for in ground contact) preservative treated vertical support posts. Concrete pads are poured in-situ into excavated holes to form the foundations for the support posts. Protective butyl joist cap tape is used to protect the top of the structure from moisture. We also build your deck off PVC drainage shims preventing moisture ingress from ground level and where necessary geotextile under deck weed proof membrane is installed as a matter of course. Depending on the hight of the project, the substructure is hidden behind deck horizontal skirt or vertical facia boards which follow where possible, the existing levels of the garden.

Composite deck boards have minimal expansion and contraction with changes in temperature. Expansion and contraction are most significant where extreme temperature changes occur. For example, gaps between boards varying between of 3mm to 5mm side to side and 1mm to 5mm where they sporadically butt are commonplace but greater and lesser can occur.
