When a deck needs restoring
A timber deck that has greyed, feels rough, shows splits or has lost its finish is a restoration candidate. The work usually means cleaning, sanding the surface, repairing or replacing damaged boards and applying a coating. It is cheaper than rebuilding if the frame beneath is sound, which is the first thing to check.
The recoating cycle
A national guide says treated pine and hardwood decks need cleaning and recoating with oil or stain, typically every 12 to 24 months in full Australian sun, and less often in shade. A professional clean and recoat for a modest deck commonly runs into the hundreds of dollars, according to the guide, while a DIY job costs a weekend and materials.
What happens if you skip it
The guide says that if the cycle is skipped, boards grey, split and check, which shortens their life and turns a maintenance item into a replacement item. Over ten years, it says, recoating a pine deck can add a meaningful share of its original build cost. A deck that has been neglected costs more to bring back.
Cleaning first
Restoration begins with cleaning to remove dirt, mould and old coating. A pressure washer on a high setting can raise the grain of soft timber, so ask the business how it cleans and at what pressure. Coolum Beach, which Wikipedia describes as a beachside town beneath Mount Coolum, has many decks that catch coastal weather.
Sanding
Sanding removes weathered fibres and old coating so that the new finish can soak in. Ask whether the quote includes the whole surface, the edges and the steps, and whether fixings will be punched below the surface first. Sanding over proud screws damages the sander and the boards.
Oil or stain
Oils soak in and are easy to refresh. Stains add pigment and can hide wear. The guide says a coating is needed on day one on pine and that hardwood needs oiling to hold its colour. Ask for the product name, the number of coats and the recoat interval in writing, and keep the tin label.
Board repairs
Boards with deep splits, rot or loose fixings may need replacing. A replacement board will not match a weathered run until it ages, so ask whether the quote includes a sample of how it will look. Where boards have been fixed down with nails that have lifted, ask for screws.
Check the frame
The guide says the substructure has its own service life and that treated pine framing in a damp, poorly ventilated space can need attention before the boards do. A restoration that coats over a failing frame is money wasted. Ask the business to inspect the underside and report on what it finds in writing.
Ventilation and termites
Ventilation clearance, drainage away from footings and termite protection are, in the guide's words, the cheapest lifecycle insurance a deck can have. Ask about airflow and signs of termites, and whether a pest inspection is wise before any money goes into the surface.
Does restoration need approval?
Sunshine Coast Council lists building work such as new decks and alterations in its permit list. Cleaning and recoating is maintenance, but replacing a large share of a structure, adding a roof or changing a balustrade can change the answer. Ask a private building certifier if you plan more than care work.
Licences
The QBCC says a licence is required for building work valued over $3,300. Restoration that includes structural repairs can pass that. Ask each business which licence it holds, and what its warranty covers on the new coating. We do not say any business is licensed.
Preparing the site
Move furniture, clear pot plants and cover nearby surfaces. Ask who will protect plants, walls and glass from oil and sanding dust. Check that the business will not work in rain or when boards are damp, because coatings need dry timber.
Planning the next recoat
Put the next recoat date in your calendar when the job finishes. Ask the business to tell you the product, the date and the interval. Shaded decks need less frequent work, and decks in full afternoon sun need more.
What to ask before you sign
Ask for the cleaning method, the sanding grade, the number of coats and the name of the product in writing, and for the date the business will return if the coating fails. Compare at least two written quotes.
How often should a timber deck be recoated?
The guide says every 12 to 24 months in full Australian sun and less often in shade.
How much does a clean and recoat cost?
The guide says a professional clean and recoat for a modest deck commonly runs into the hundreds of dollars. It is not a Sunshine Coast quote.
Is restoration cheaper than replacement?
Often, if the frame is sound. Ask the business to inspect the frame and report in writing.
Does restoration need a building approval?
Care work usually does not, but adding a roof, a balustrade or larger structural changes can. Ask a certifier.
