A safe timber deck is one that is one that is regularly maintained. Timber rot, cracks, splitting, warping and discolouration, are all problems waiting to happen thanks to our harsh climate. These simple steps will help you get the most from you deck.

Even so, the best timber can deteriorate if not maintained properly. To get the most from your deck, check for deterioration at least twice a year, and certainly in spring and autumn.

To ensure it stays in top condition you should clean your deck every year and treat it every two years.

  • Tinted preservatives add a little colour to the wood and are available in a variety of shades. These come in two main types, stains and solid finishes.  Stains allow  the grain of the timber to show through, where solid finishes give a uniform look to the deck.
