Looking after your render in Bendigo.
Render needs almost no maintenance, which is exactly why it gets none, and why so many Bendigo facades need work at year twelve instead of year twenty-five. There are five habits. None of them takes long.
Five things, and that is genuinely all.
- Wash it once a year. Autumn is the time, after the summer dust has settled and before winter drives it into the surface.
- Walk around it once a year. Look for new cracks, tap for drummy patches. Ten minutes.
- Keep garden beds and mulch clear of the damp-proof course. This one causes more render failures than any other maintenance issue.
- Keep gutters and downpipes working. Water running down a wall is render’s worst enemy in a frost climate.
- Refresh the coating every 8 to 15 years depending on the elevation.
Do those and a render system comfortably runs 25 to 30 years, as covered in how long render lasts. Skip them and you are paying for repairs a decade early. The maths is not close. All five are genuinely homeowner jobs, which is not true of render itself. Where that line sits is the whole subject of DIY vs professional rendering.
How to clean render without wrecking it.
Low pressure and patience. The mistake almost everyone makes is treating a rendered wall like a concrete driveway. A 3,000 PSI machine with a pencil tip held 50 millimetres from a texture coat will strip it to bare render in seconds and leave permanent tracking marks that no amount of recoating fully hides. We repair that damage several times a year, and it is always self-inflicted.
The safe envelope: keep it under about 1,200 PSI, use a 25 or 40 degree fan tip, stay at least 300 millimetres back from the wall, and work top to bottom so you are not driving dirty water into clean render. Never aim upward into a control joint, under a bead, or at a window head, because that is how you get water behind the render rather than off it. For general grime, warm water with a little mild detergent and a soft broom does most of what a pressure washer does, and it cannot damage anything.
The green wall problem.
Every second south-facing wall in Bendigo grows a green film, and it is algae rather than mould in most cases. It grows because a south wall gets no sun and stays damp right through our cold, still winters. Treat it with a diluted bleach solution or a proprietary render-safe wash, leave it 15 to 20 minutes to work, then rinse at low pressure.
Then fix why the wall is wet, or you are doing this again next winter. Nine times in ten it is one of three things: a shrub planted hard against the wall holding moisture and stopping airflow, a blocked gutter or split downpipe dribbling down the face, or a garden bed built up so high that the wall wicks from the soil. Kill the algae and change nothing and you have bought a season.
The one that costs people the most money.
Keep soil, mulch, garden beds, decking and paving clear of the damp-proof course. You want a visible gap of at least 75 millimetres between the top of the soil and the bottom of the render, and you want it to stay that way.
Here is how it goes wrong, and it goes wrong constantly. The house is rendered correctly, stopping short of the DPC. Five years later the owner mulches the garden bed. Then mulches it again. Then again. By year twelve the bed has crept up 150 millimetres and is sitting against the render, and now ground moisture has a direct bridge into the wall. The render starts blowing at the base, the white salt bloom appears, and a job that would have been a $400 afternoon with a shovel becomes a salt damp repair running into thousands.
Same story with a new deck built at render height, or paving laid over the old paving instead of replacing it. Every one of those is invisible on the day and expensive at year twelve. If you are having landscaping done, tell the landscaper where the DPC is. They will not look for it.
What a recoat cycle costs, done properly.
A 150 square metre rendered facade in Strathdale, acrylic system, now 13 years old. The south and east walls still look respectable. The north and west walls are chalky, faded a shade, and shedding a fine powder onto your hand when you rub them. That chalking is the UV load: 2,100 hours of Bendigo sunshine a year does that to any coating, and it is normal.
The whole-house recoat is roughly $5,400 in 2026 at $30 to $45 per square metre for a texture coat, scaffold included. But you do not have to do it all. Recoating only the north and west elevations, about 80 square metres, lands near $3,100. Then the south and east go two or three years later when they are genuinely due.
Splitting it like that matches how the walls actually wear, spreads the cost, and means each elevation gets recoated when it needs it instead of when its neighbour does. The only caveat is colour: if you are changing shade, do the whole house at once or you will have two colours for three years. If you are staying with the same colour, split it. Full rates are in the rendering cost guide, and the seasonal guide explains why autumn is the window for coating work too.

Render maintenance questions.
How do I clean rendered walls in Bendigo?
Low pressure and patience. Use a garden hose or a pressure washer turned down to about 1,200 PSI with a wide fan tip held at least 300 millimetres from the wall, working top to bottom. High pressure held close will strip a texture coat clean off and cut grooves into the render, and we repair that damage regularly. For general grime, warm water with a little mild detergent and a soft broom does most of the job. Do it once a year, ideally in autumn after the summer dust has settled and before winter drives it in.
How often should render be recoated in Bendigo?
Every 12 to 15 years on the shaded south and east elevations, and every 8 to 12 years on the north and west walls that take the full afternoon sun. Bendigo gets roughly 2,100 hours of sunshine a year and that UV load is what ages a coating, not the render underneath. You do not have to do the whole house at once. Recoating the north and west walls on a shorter cycle than the south and east is perfectly sound, costs less each time, and matches how the walls actually wear.
How do I get rid of green mould on my rendered wall?
The green film on a south-facing Bendigo wall is algae, and it grows because that wall stays damp through our cold, still winters. Treat it with a diluted bleach solution or a proprietary render-safe mould wash, leave it to work for 15 to 20 minutes, then rinse at low pressure. It will come back unless you fix why the wall stays wet: cut back the shrub planted hard against it, clear the blocked gutter that is dribbling down the face, and let some air move. Killing the algae without changing the conditions just buys you a season.
What maintenance does render actually need?
Genuinely very little, which is why it gets neglected. An annual wash, an annual walk-around to check for new cracks and drummy patches, keeping garden beds and mulch clear of the damp-proof course, keeping gutters and downpipes working so water is not running down the wall, and a coating refresh every 8 to 15 years depending on the elevation. That is the entire list. Do those five things and a render system will comfortably run 25 to 30 years. Skip them and you will be paying for repairs at year twelve.
Can I pressure wash my rendered house?
Yes, if you turn it down. The mistake is treating a rendered wall like a concrete driveway. A 3,000 PSI machine with a pencil tip held 50 millimetres from a texture coat will strip it to bare render in seconds and leave permanent tracking. Keep it under about 1,200 PSI, use a 25 or 40 degree fan tip, stay at least 300 millimetres back, work top to bottom, and never aim upward into a joint or under a bead where you will drive water behind the render. If you are unsure, a hose and a soft broom will not damage anything.
