A full beach house repaint on the Mornington Peninsula generally lands between $8,000 and $18,000 for exterior work, with weatherboard at the top end and rendered walls at the lower end. Broken down wall by wall, a typical single-storey coastal home carries $1,800 to $4,500 on the exposed western elevation, $1,200 to $2,800 on each side elevation and $600 to $1,600 on the sheltered southern or eastern face. Every figure needs a site inspection to become a real quote, because one elevation rarely matches the others.
That imbalance is the point. The best painters do not price a beach house as one average surface. They price four elevations with four different histories.
The wall-by-wall breakdown
| Element | Typical range | Why it sits there |
|---|---|---|
| West or north-west elevation | $1,800 – $4,500 | Full sun plus salt-laden wind, most likely to need three coats and repair |
| North elevation | $1,400 – $3,200 | Heavy UV, chalking common, usually sound underneath |
| Side elevations, each | $1,200 – $2,800 | Access is often the constraint, not condition |
| South or east elevation | $600 – $1,600 | Least UV, but mould and lichen are frequent |
| Eaves, fascia and barge | $900 – $2,600 | Ladder or scaffold work, fine cutting, often the first to fail |
| Windows and doors, per opening | $120 – $380 | Timber sashes cost more than aluminium reveals |
| Verandah posts, beams and ceiling | $800 – $2,400 | Complex cutting, exposed underside, salt collects here |
| Deck re-oil | $25 – $45 per square metre | Clean, dry, two coats of penetrating oil |
| Full deck restoration | $45 – $80 per square metre | Strip, sand, board replacement, rebuild the finish |
| Soft wash before painting | $260 – $735 | Whole house, removes salt and biological growth |
| Roof clean | $315 – $1,375 | Pitch, material and anchor point requirements |
Why the west wall costs double the south wall
On the Peninsula the prevailing weather comes off the water, and the western and north-western faces take the sun for the hottest part of the day. Salt settles on the film, holds moisture against it and works into every joint and fixing. Ultraviolet light breaks down the binder from the outside.
So the west wall is usually chalking, sometimes cracking, and often needs bare-substrate priming across a large area. That means three coats rather than two, more filling and more time on ladders. The south wall of the same house may need only a wash, a light sand and two coats.
Substrate rates you can check the quote against
- Weatherboard: $45 to $80 per square metre, and roughly 95 per cent of southern Peninsula housing stock is detached timber or fibro
- Rendered walls: $30 to $55 per square metre
- General exterior: $30 to $80 per square metre depending on profile and access
- Labour behind those rates: $75 to $95 per hour plus GST, or $400 to $800 per painter per day
Multiply your wall area by the relevant band and you have a defensible expectation before the first painter arrives. If you own a weatherboard home, budget toward the upper half of every range, and expect the best painters to say so at the inspection rather than after.
The line items people forget
Three things blow out beach house budgets more often than the painting itself. The first is timber repair. Coastal boards rot at the ends and behind downpipes, and a painter who does not cut those out is covering a problem you will pay for twice.
The second is access. A house on a slope may need scaffold, which can add $1,200 to $3,500 before a brush is lifted.
The third is the deck. Owners often do the walls and leave the deck for next year, then find the boards have gone past re-oiling into full restoration at roughly double the rate.
How often you will be paying this
Inland, a premium exterior system holds for seven to twelve years. Within sight of the water, five to seven is realistic. Rinsing the exterior walls with fresh water every three to six months genuinely extends that, and it costs nothing but time.
For an absentee owner, that maintenance is the hard part, which is why painting for coastal second homes is usually structured around scheduled visits rather than one large job every seven years.
Turning ranges into a real number
Take this table to your next quote conversation and ask for each elevation priced separately. The best painters will do it without complaint, because that is how they estimated the job anyway. When you want a measured figure, book a site inspection through our contact page.
Frequently Asked Questions
How much does it cost to repaint a beach house on the Mornington Peninsula?
A full exterior repaint on a coastal Peninsula home typically costs $8,000 to $18,000, with weatherboard at the top of that range and rendered walls lower. Individual elevations range from about $600 for a sheltered south wall to $4,500 for an exposed western face. A site inspection is required for an accurate quote.
Why does one wall cost more to paint than another?
Exposure. West and north-west elevations take the most ultraviolet light and the most salt-laden wind, so they chalk, crack and lose adhesion first. Those walls often need bare-substrate priming and three coats, while a sheltered south wall may need only a wash, a light sand and two coats of the same product.
Should I do the deck at the same time as the walls?
Usually yes. Deck re-oiling costs $25 to $45 per square metre while a full restoration costs $45 to $80, and a deck left too long moves from the first category to the second. Doing it alongside the walls also avoids paying twice for site setup, access equipment and travel.
Do I need the house soft washed before painting?
On the coast, almost always. Soft washing a full house costs $260 to $735 and removes salt deposits, mould and lichen that would otherwise sit under the new film and undermine adhesion. Skipping it is one of the most common reasons a coastal repaint fails years earlier than it should.
