Deck Replacements Sunshine Coast

Do you have an older Sunshine Coast deck that looks neglected and requires a new facelift? Maybe a deck refreshment is all your deck needs to get it looking amazing and ensure that it can withstand the harsh outdoor climate. The difference between a refresh (restoration) and a replacement is heavily influenced by the condition of the existing decking boards and the initial construction quality. A simple deck inspection from one of our Sunshine Coast deck builders will reveal whether the decking can be restored or has passed its due date.

Deck Replacement Options

When it comes time to replace or upgrade your decking boards, there are 3 options to consider:

Remove and replace with the same decking
Remove and replace with alternative natural timber decking
Remove and replace with composite timber

Natural Timber - Some great options for natural timber decking include the following species and their common available sizes:

ACQ Pine 90 x 22
Losp Pine 90 x 22
Pacific Jarrah 90x19
Yellow Balau 90x19
Kwila/Merbau 90x19

We have a huge range of brands and styles to select from. Along with our professional advice and industry experience, we can help you select the best composite board for your deck.

Existing Deck - Restoration Or Refresh

A timber deck requires a quality coating system to protect it from the harsh outdoor elements. A deck coating system will enhance the timber's performance and extend its lifespan during the ongoing battle with sun and rain. How often your deck protection coating needs to be refreshed will depend on the location and exposure of your timber deck.

Replacement Coating

A failing deck protection coating can look unsightly and increase the chances of premature timber failure. These coatings need to be stripped right back to bare timber by using products or sanding the timber. If dome headnails have been used during the construction, sanding the deck is not an option. For bullet head nails, screws or clip systems, the deck can be sanded using professional sanding equipment. Once the deck has been restored to bare timber, a new coating system can be applied, usually requiring an initial 3-coat system. Once the new coating has been completed, the deck is back to full strength and should be reviewed every 3 months to assess its next ‘top up’ application.

Refresh Coating

Deck protection coatings that are in order and simply need to be ‘topped up’ require a simple surface clean followed by one coat of the product initially used. Mixing different products may cause the coatings to react and prematurely fail. Once the new coating has been finished and the deck is back to full strength it should be reviewed every 3 months to assess its next application.

For all our decks we use and support the Intergrain product to achieve great results, which have been proven to stand the test of the harsh Australian climate.

Your Questions Answered

First, identify the decking board or portion of decking that needs replacing. It is advised to always replace lengths spanning greater than 3 joists. Establish the centreline of the joist that you plan to cut along. If multiple boards need to be replaced, ensure you stagger the joins.

Using a multi-tool with a wood-cutting blade, cut square through the board over the centre line of the joist. A multi-tool is the ideal tool for this job as cutting through with a circular saw may prove to be difficult without overcutting. Remove the damaged section of board.

Measure the space and carefully cut a replacement board to the same length. Seal all end grains of the decking before installing. Fasten the new decking board in place with fixings to match the existing. Apply timber coatings to protect the new decking board and match with the existing deck.

It is advised to always ensure the deck is safe and the correct safety signage is visable before removing any subframe. Identify the rotten or failing joist that needs replacing. Remove the fixings connecting the decking to the joist. Remove the fixings connecting the joist to the bearers. Once the fixings have been removed, slide the joist out from its position.

It is important to ensure the replacement joist is the same specification, matching the size, grade and treatment of the original joist. Cut the new joist to the required length and seal both ends. Install a rubber joist protection over the top face of the joists to extend its life span and reduce water penetration from above.

Reinstall fixings to connect the joist to the bearers, followed by the fixings connecting the decking to the new joist. Clean area and reopen decking for use.

Water and moisture are timber's greatest enemies. Here are some helpful tips on preventing costly wood rot in your deck.

If water gets into cracks or under sealed surfaces and doesn’t dry out, it can cause wood rot. Unsealed or incorrectly treated timbers are especially susceptible to decay and rot. Timbers that are low to the ground or exposed to moist, damp environments are likely to have a shorter lifespan than those in dry conditions with good ventilation. Once rot and decay start, it can be very costly to repair, and often, the only cure is to replace the damaged timber. Left untreated, wood rot may spread, infecting other wood parts and possibly leading to structural damage.

Some tips on how to prevent wood rot:

Start with quality construction – jumping into DIY might seem easy. However, there is a lot to consider when it comes to construction. Using a professional building company to start with is a great way to ensure your structure is built to fit its environment. The initial upfront cost for a licenced contractor and a quality build will save you money down the track from unexpected repairs.
Look for trouble spots – a great defence to rot is as simple as using your eyes and best of all it’s free! Once a year, look over your structure to identify any potential zones that are susceptible to decay or rot.
Improve ventilation – increased ventilation ensures that wet timber can dry out quickly. Don’t block the sides of your structure or deck, which may prevent a cross breeze.
Maintain deck coating systems – ensure your deck coating system is up to date and still effective. A water beading test is a simple way to check the quality of your deck coating system.

Eliminating the opportunities for rot and decay to start within your deck is a great way to ensure that you can enjoy a long life in your outdoor space for many years to come.
