Deck restoration brings a weathered timber deck back to a sound, even surface and protects it with a new exterior coating. Depending on the condition of the deck, it can be as simple as a thorough clean and a fresh coat of oil, or as involved as replacing boards, punching nails, sanding the whole surface and applying several coats.
Bendigo is hard on outdoor timber. Long-term Bureau of Meteorology averages for Bendigo Airport show mean January maximums above 30 °C, low summer humidity and only around 510 mm of rain a year. Strong sun breaks down coatings and greys exposed timber, while hot dry spells followed by cold wet winters make boards shrink, swell and check.
Bendigo Floor Sanders is an enquiry service, and does not restore decks itself. With your consent, we pass your enquiry to an independent local contractor, once one is appointed, who will inspect and quote. Some deck work, such as structural repairs or new framing, may need a builder or carpenter.
Clean and recoat, or sand?
This is the most common question people ask about decks, and the answer depends on what's on the surface now.
A clean and recoat may be enough when:
- the boards are smooth to walk on, with no lifted grain or splinters;
- the existing oil or stain has faded but hasn't peeled or flaked;
- water soaks into the timber rather than beading on a failed film;
- you're keeping the same type of product.
Sanding is usually needed when:
- the timber is grey, rough or splintering;
- an old film coating (such as a varnish or paint-like stain) is peeling;
- you want to change colour or switch from a film coating to a penetrating oil;
- boards are cupped or uneven;
- patches under pot plants or outdoor furniture have aged differently from the rest.
Sanding only patches of a deck tends to leave a visible difference. If sanding is needed, the whole surface is usually done.
What a full deck restoration involves
- Inspection. The contractor checks for loose, split or rotten boards, rusty or raised fixings, and signs of problems in the frame.
- Repairs. Damaged boards are replaced, popped nails are punched or replaced with screws, and fixings are set below the surface so they don't catch on sanding machines.
- Cleaning. A deck cleaner or stripper removes dirt, mould and failing coating. A pressure washer may be used carefully; too much pressure can raise and damage the grain.
- Drying. The timber must be dry before sanding or coating. In Bendigo summers that may only take a day or two, but after winter rain it can take longer.
- Sanding. A drum or orbital deck sander takes the surface back to fresh timber, with edges and areas around posts done by hand or with an edger.
- Coating. Usually two or more coats of a decking oil or exterior stain, applied in suitable weather.
Choosing a deck coating
- Penetrating decking oils soak into the timber and wear gradually. They don't peel, and maintenance is a clean and fresh coat. In strong sun they may need recoating relatively often.
- Water-based deck stains offer colour and UV protection, are low odour and dry quickly. Product choice matters, as some form more of a surface film than others.
- Film-forming varnishes and paint-like coatings can look good at first but tend to peel outdoors when timber moves, and stripping them later is hard work.
Darker, pigmented products generally offer more UV protection than clear oils. Follow the manufacturer's directions on temperature, because applying in direct summer sun can make coatings dry too quickly and look patchy.
Verandahs on period homes
Many Bendigo heritage homes have timber verandah floors, often under a roof but exposed to weather at the edges. The City of Greater Bendigo's heritage design guidelines describe verandahs as a characteristic feature of the city's period houses. Restoration is similar to a deck, though verandah boards are often narrower tongue-and-groove boards that may be painted. Check whether your property is covered by a heritage overlay before changing its appearance, and see the lead paint note below.
Safety points
- Old paint. Paint on verandah floors and decks of older homes may contain lead. Australian Government guidance warns against dry sanding lead paint.
- CCA-treated pine. Many decks are built from treated pine. Sanding dust from treated timber should be controlled, and offcuts shouldn't be burnt.
- Structure. Soft or springy areas can mean rot in joists or bearers underneath. That needs a builder's assessment, not just new decking boards.
Keeping the deck in good shape
- Sweep regularly so leaves and dirt don't hold moisture against the boards.
- Keep gaps between boards clear so water can drain.
- Move pots and furniture occasionally so they don't leave pale or damp patches.
- Recoat when water stops beading or soaking evenly and the colour starts to fade. In Bendigo's sun, north- and west-facing decks may need attention more often.
What affects the price
Deck restoration is usually quoted per square metre. The deck's condition, the amount of repair, the number of coats, access, stairs and balustrades all affect the total. Balustrades in particular are slow, detailed work and are often priced separately. See typical prices for published ranges and sources.
Frequently asked questions
How often should a deck be oiled in Bendigo?
It depends on sun exposure, the product and how much use the deck gets. Many oil-based products need a maintenance coat every year or two in exposed spots. A simple test: if water no longer beads or soaks in evenly, it's time.
Can a grey deck be brought back?
Usually, yes. Greying is the surface layer of timber breaking down in sunlight. Sanding removes it to reveal fresh timber, as long as the boards themselves are still sound.
Is pressure washing bad for a deck?
Not necessarily, but too much pressure or holding the nozzle too close can raise fibres and gouge softer timber. Many contractors use a deck cleaner and a gentle wash, then sand if the surface is rough.
What's the best time of year for deck work in Bendigo?
Spring and autumn often give the best combination of dry timber and moderate temperatures. Summer heat can make coatings dry too fast, and winter rain can keep timber too damp to coat. Follow your contractor's advice and the product directions.
Do I need to sand the whole deck or just the bad parts?
If sanding is needed, the whole surface is usually done. Patch sanding tends to leave areas that look different from the rest once oiled.
