Concrete driveways, paving and masonry take high pressure well. Aged roof tiles, old render and soft timber do not. Knowing which is which is the whole job and on a Mount Claremont home it is the difference between a clean surface and a damaged one.
Pressure Cleaning in Mount Claremont: the short version
The machine is the easy part. Judging pressure for a given surface, choosing the right nozzle and working at the correct distance is what separates a clean from damage. Detail sits on our pressure cleaning page.
Why Mount Claremont roofs behave the way they do
Mount Claremont, known for most of its history as Graylands, is one of the most institutional suburbs in Perth. Hospitals, military and migrant facilities, colleges and university land have occupied much of it and the residential suburb grew as those uses were progressively wound back from the 1950s onward. That produces the defining consideration here: a great deal of the housing sits on or beside former institutional land. Checking the land-use history of a particular parcel is worth doing, because ground that once carried a hospital, a camp or a depot can hold made ground, buried services and demolition fill beneath later housing. It also means build eras vary widely, since land came to market in stages, anything from 1950s and 60s stock to very recent development on newly released parcels. Two councils, one suburb Mount Claremont straddles the boundary between the City of Nedlands and the Town of Cambridge. It adds up. Planning rules, heritage listings and approval records differ between them, so before relying on what is permitted, or trying to trace whether an addition was approved, confirm. Council actually holds the file for that address. The suburb also contains the heritage-listed Swanbourne Hospital Conservation Area, built from 1903 and for much of the twentieth century the largest stand-alone psychiatric hospital in the state. Properties within or adjoining the conservation area face real constraints on what may be altered.What that means for pressure cleaning in Mount Claremont
Old buildings need the lightest approach available. Soft limestone, lime mortar and original render are all softer than the water pressure most machines deliver and damage to them is permanent.
Driveways and paths on these properties are typically sound concrete and take pressure well, so the same visit can involve two completely different approaches.
Metalwork here is frequently already compromised by corrosion, so pressure that would be safe elsewhere can drive water behind failing edges.
Mount Claremont roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Timber decking, greyed | Soft grain, raises easily | Low pressure with the grain |
| Limestone, historic | Soft and permeable | Specialist approach, not high pressure |
| Concrete driveway, general grime | Sound surface, hard wearing | High pressure, fan tip |
| Slippery paving on the shaded side | Algae holding moisture | Treat, then clean at moderate pressure |
Guide only. Every roof differs, which is why we look before quoting.

Roof Cleaning in Mount Claremont
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Mount Claremont roof and gets it back to a clean, even surface — either as a standalone tidy-up or as the first stage of a restoration. We treat the growth first so it dies at the root, then clean at a pressure matched to the tile so we lift the grime without stripping the surface or driving water under the laps.
Left alone, that growth holds moisture against the tiles and works into the pointing, which is why we treat rather than just blast it — the same method we use through nearby Swanbourne. We check the roof over while we’re up there and flag anything that needs attention, so a clean doesn’t paper over a repair that’s quietly getting worse. On steeper or two-storey Mount Claremont roofs we work off proper anchorage and stay off the tiles where we can, so the clean lifts the grime without cracking the very surface it’s meant to protect, and we’ll let you know if the roof would be better served by a full restoration.

Roof Restoration in Mount Claremont
Learn moreA roof restoration renews a tired but sound Mount Claremont roof for a fraction of replacement: we treat the moss and lichen, high-pressure clean, replace broken tiles, re-bed and re-point the ridge caps in a flexible compound, then seal and coat with a Dulux AcraTex membrane as accredited applicators.
It’s the right call when the tiles have decades left but the surface and pointing are gone — the same judgement we bring to nearby Claremont. We’ll tell you honestly whether a restoration suits your roof or whether repairs or a re-roof make more sense, and the finished job carries both a manufacturer coating warranty and our 10-year workmanship warranty. Most Mount Claremont homes take two to three days depending on the repairs needed before coating. As accredited applicators we prepare to the manufacturer’s specification, so the membrane actually holds — a coating only lasts if the surface beneath it was treated, cleaned and repaired properly first, which is exactly where a cheap spray-over fails within a couple of summers.

Roof Repairs in Mount Claremont
Learn moreMost Mount Claremont roof problems come down to a handful of failures: cracked or slipped tiles, perished ridge pointing, rusted valley irons and tired flashings. We trace the leak to its actual source — which is rarely under the ceiling stain — and fix the cause, whether that’s replacing matching tiles, re-bedding and re-pointing the ridge in a flexible compound, or renewing a corroded valley.
We’ll always tell you honestly when a roof is genuinely repairable versus when the repairs are mounting up and a restoration would serve you better, as it often does through nearby Karrakatta. Prompt repair matters: a single cracked tile left through a wet winter becomes soaked insulation, stained ceilings and, eventually, damaged roof timber. Every repair is backed by our workmanship warranty, and because we photograph what we find and talk you through it, you’ll understand exactly what was wrong and what we did about it rather than being handed a bill and a shrug.

Roof Replacement in Mount Claremont
Learn moreWhen a Mount Claremont roof reaches the end of its life — porous tiles, rusted-through valleys, or a roof that’s been patched one too many times — a full re-roof is often the honest answer. We strip the old covering, check and repair the timber and battens underneath, and install a new tile or Colorbond roof with fresh sarking, valleys and flashings throughout.
A tile-to-Colorbond conversion is popular here for its lighter weight, clean lines and colour range, and because the lighter roof changes the wind uplift we reassess the tie-down as part of every conversion. We’ll also be straight about whether you’ve genuinely reached replacement or whether a restoration, as we do through nearby Peppermint Grove, would renew the roof for a fraction of the cost. Every re-roof is engineered and tied down to Australian Standards and backed by our 10-year workmanship warranty, and we handle the guttering, flashings and tie-down as one job so nothing is left for you to chase afterwards.

Roof Inspection in Mount Claremont
Learn moreA roof inspection is the cheapest way to know exactly what your Mount Claremont roof needs before you commit to anything — or before you buy. We get onto the roof and into the roof space, physically checking the tiles, pointing, valleys, flashings, gutters and the structural timber, then hand back a clear written report with photographs.
On older homes we test the timber for rot, termite damage and delignification; on newer ones we look for the builder-grade detailing faults that leak early. It’s the same thorough check we run through nearby Cottesloe, and it’s what tells you whether a roof needs a minor repair, a restoration or something structural. If you’re buying a home, an inspection of the one part most people skip — the roof space — is money very well spent, and the written report gives you something concrete to put in front of an agent, a buyer or your insurer rather than a verbal all-clear.

06Roof Carpentry in Mount Claremont

Roof Carpentry in Mount Claremont
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Mount Claremont homes we repair and rebuild that framing to standard: sistering weakened members, replacing rotted or termite-damaged timber, and reinstating trusses that have been cut for a skylight, duct or downlight.
We also test for delignification, the chemical breakdown that leaves roof timber looking sound but unable to hold a fixing — the same treatment we carry out through nearby Swanbourne where the timber is worth saving rather than replacing. As registered builders we can certify structural carpentry, which a general handyman can’t, and we assess the whole load path while we’re in the roof space so a repair addresses the cause, not just the symptom. Where a member is load-bearing we prop it safely with acrow props and work to a structural engineer’s design before anything is cut — it’s the natural companion to our tie-down and structural-defect work.

Local conditions in Mount Claremont
An unusually institutional suburb, hospitals, military and migrant facilities, colleges and university land. Much of the residential development sits on or beside FORMER INSTITUTIONAL LAND released progressively since the 1950s. That means checking the land-use history of a parcel: former hospital, camp or depot ground can carry made ground, buried services and demolition fill.
The suburb straddles TWO councils, the City of Nedlands and the Town of Cambridge. Planning rules, heritage listings and approval records differ depending on which side a property sits, so confirm which council actually holds the file.
Because land was released in stages as institutions were wound back, build eras vary widely, 1950s-60s through to recent development on newly released parcels. Establish the vintage.
We cover the whole of the City of Nedlands. Around Mount Claremont that takes in Nedlands, Shenton Park and Perth. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.

Recent work


What the work involves
- Match nozzle and standoff to the surface. A pencil jet concentrates enormous force into a tiny area and will carve concrete. A fan tip spreads the same energy across a band. Doubling the distance from the surface dramatically reduces impact force
- Work down, never uphill under laps. On any roof or overlapping surface, driving water uphill forces it behind and underneath. That damage is invisible on the day and appears as a stained ceiling weeks later
- Protect surrounds and manage the runoff. Plants covered, windows and fittings protected and the considerable volume of dirty water directed somewhere sensible rather than into a soakwell it will block
Common questions about pressure cleaning in Mount Claremont
What about asbestos?
Never pressure clean it. Cleaning fibre cement sheeting releases fibres and it is both dangerous and unlawful. We identify suspected material and decline the work rather than proceed.
Where does all the water go?
Into your drainage, carrying whatever came off the surface. On a large job that is a genuine volume and it can silt a soakwell. Managing the runoff is part of doing it properly.
Is soft washing better?
On fragile surfaces, considerably. It applies treatment chemistry at low pressure and lets it work over time, then rinses gently. It takes longer and it does not damage what it is cleaning.
Can you clean before painting?
Yes and preparation is exactly where pressure cleaning earns its place. Coatings adhere to the substrate, not to what is sitting on it.
Do you work throughout Mount Claremont?
Yes and the surrounding suburbs. Ring 0421 768 842 and tell us your street. If we are not the right people for the job we will say so rather than quoting anyway.
How to tell a real assessment from a sales visit
Ask who will actually be on the roof. Whether the crew are employees or subcontractors matters most when a warranty claim arises, since a workmanship warranty from a business that subcontracts everything and supervises nothing is a document rather than a protection.
