A multi-unit residential building wears differently to a standalone home. By the time the committee notices, render is streaked across the elevations, mould has crept along the shaded south-facing walls, organic staining sits under eaves and balconies, and cobwebs have settled into the corners of stairwells and shared corridors. These signs accumulate slowly across the years between AGMs, and a single coordinated exterior wash often shifts the property’s whole presentation back to where the committee wants it. For property managers, a tired-looking building affects resident satisfaction, tenant turnover, and even valuations, which makes a coordinated exterior wash one of the most cost-effective items on the body corporate calendar.
Mr Sparkle Window Cleaning is the Melbourne team that handles building washing for body corporate and owner corporation properties, and we do quite a bit of it. We use a soft-wash approach so render, paint, weatherboards, brick, and coated metal stay intact while the chemistry lifts mould, algae, and cobwebs. We coordinate directly with your building manager, work the building section by section, and keep results consistent across multiple elevations. Honest scope: accessible multi-unit and low-rise buildings, not high-rise, not post-construction.
Most quotes go out within 30 minutes to an hour, around 90% are handled remotely with no site visit needed, and we can include exterior window cleaning in the same visit if it’s already on your maintenance plan. Call us today on (03) 7073 2133 to get on the schedule.
Building washing is custom-quoted per property because body corporate and owner corporation buildings vary too widely for a fixed price range to be useful. A six-unit walk-up, a thirty-unit complex, and a courtyard cluster of townhouses are three completely different jobs, and your quote needs to reflect what’s actually in front of us.
Here’s what we can be specific about upfront:
The factors that shape your quote are practical, not arbitrary:
Once your committee approves the quote, a 50% deposit confirms the booking. It’s payable online with no credit card fees and is calculated against the agreed quote. Pricing details for your specific building are available on request, so call us on (03) 7073 2133 if you’d rather walk through the numbers verbally.
Committee approvals, board meetings, and AGM cycles can slow things down on the client side, so we keep the quote turnaround fast on our end. The only timeline you’re managing is the approval cycle you already control. During business hours we usually respond to inquiries within one to five minutes (often within one minute), and most building washing quotes go out within 30 minutes to an hour. Around 90% of those quotes are completed remotely using Google Earth, Google Street View, real estate listing photos, or photos sent through by the property manager. For larger or more complex buildings, photos of the elevations, side passages, and any access constraints help us put a more precise number together. If you’d prefer an in-person assessment, useful for older buildings, complex sites, or properties with unusual surface conditions, on-site quotes are free of charge in our local service area. Once approved, we lock in scheduling around the building’s preferred timing.
Many of the body corporate properties we work with already have exterior window cleaning on a recurring schedule, and the natural fit is to coordinate both services in the same visit. Building washing leaves windows rinsed but water-spotted as a by-product of the process, and finishing them with our water-fed pole and pure water system ties walls and glass together so the entire exterior reads as freshly maintained.
If your committee wants to combine building washing with a recurring window cleaning schedule, we’ll structure the quote around it. The standing options are:
For commercial-specific or stacked discounts beyond these, current offers are confirmed at the time of quoting.
We soft-wash the exterior surfaces common across Melbourne body corporate and owner corporation properties, including render, brick, weatherboards, painted exterior walls, and metal cladding, along with the windows, frames, eaves, and shared exterior areas that frame the property’s presentation.
Render is the most common surface we encounter on Melbourne body corporate buildings, and it’s also the one we have the most direct conversations about with property managers. Because render is porous, mould, algae, and lichen embed deeply into the surface rather than sitting on top. For render that’s been neglected, we may need to run two or three soap-dwell-rinse cycles to lift the growth properly. We don’t hit it harder with pressure; we work it longer with chemistry, applying soap, letting it dwell, rinsing it down, inspecting, and repeating until the surface comes back.
Brick follows the same overall soft-wash process as render but is less porous, so growth typically lifts on the first pass. The point worth flagging clearly: if mortar is already failing or breaking apart, we adjust the approach so the cleaning process doesn’t worsen what’s already there. We flag mortar concerns during the on-site walkthrough so the property manager can fold masonry repair into broader maintenance planning if needed.
Weatherboards (timber or composite) are generally easier to wash than render because the surface is less porous and growth lifts more readily. Painted exterior walls (over render, weatherboards, or fibre cement) handle soft washing well, since the chemistry breaks down growth without the pressure that strips paint. We adjust technique to suit the surface in front of us rather than running the same configuration on every building.
Metal cladding, including Colorbond and other coated metal facade systems, sometimes needs agitation rather than soft-wash chemistry alone. Our method here is water-fed pole brushing across the facade paired with a pure water rinse, used for situations where surface grime, oxidation-style residue, or coastal salt buildup doesn’t release with detergent and rinse alone. Our scope is surface cleaning, so cladding that has progressed into oxidation damage will need a metal restoration specialist rather than a wash.
The parts of a body corporate building that look most neglected are usually the eaves, the window frames, and the corners where cobwebs accumulate. These get attention as part of the wash. Frames are scrubbed, cobwebs around frames are physically removed before we touch the glass, and eaves are rinsed thoroughly. Property managers often comment that the cobweb removal alone makes the building look freshly maintained, before the surface wash even shows results.
For body corporate buildings with windows across multiple levels, we use a water-fed pole and pure water system. With the minerals removed from the water, exterior glass dries streak-free without traditional squeegee work on every pane. We work top-down: top windows first, middle windows next, ground-level windows last. Working in this order means upper-level rinse water falls onto windows we haven’t cleaned yet, not onto windows we’d otherwise have to redo.
Body corporate properties almost always have garden beds, mature trees, hedges, lawns, and planter boxes around the building. Plant protection is a repeated step on every wash, not a one-time precaution. Vegetation gets a thorough rinse before any chemical is applied, again during dwell time, and once more after each section is finished, which means three full rinse passes per section. We work around landscaping, not through it.
Honest boundary-setting helps trust, and there are real-world conditions where we adjust the approach:
It helps property managers if we name the commercial work that sits outside our scope upfront, before a committee approval cycle starts:
For property managers juggling tenant requests, AGM prep, and contractor coordination across multiple buildings, the worst contractor experience is silence. We aim to start the conversation within one to five minutes during business hours, and most replies land within the first minute. You can usually move on with your day before the next meeting starts.
For property managers covering multiple buildings, arranging site access just to compare quotes adds days to a maintenance cycle. Around 90% of our building washing quotes go out without that step. We work from Google Earth, Google Street View, real estate listing photos, or photos sent through by the property manager, and we book in-person assessments only when the building’s condition genuinely calls for one. In our local service area, those visits are free of charge.
Many committees ask for “pressure washing” because that’s the term they know, but the surfaces most body corporate buildings are made of (render, paint, coated cladding) need a gentler approach to come up clean while staying intact. We use soft washing instead: the same industrial machine, configured for high water volume and low pressure, paired with detergent that does the actual lifting. Organic growth comes off, and paint and porous render stay where they belong.
For body corporate buildings where render hasn’t been cleaned in years, a single soap-and-rinse pass won’t return the surface. We plan two or three full cycles into the quote upfront so older render genuinely comes back, rather than half-cleaning a building and handing the committee an awkward result. The chemical itself is SH (sodium hypochlorite, also known as bleach), the industry-standard agent for organic growth on exterior surfaces. We don’t apologise for it and we don’t claim it’s eco-friendly.
On body corporate and owner corporation jobs, the building manager is our primary point of contact, and we bring the project structure with us so you don’t have to. Resident notifications, 24-hour reminders, access coordination across locked gates and shared spaces, and on-the-day check-ins are handled to a script we’ve run on dozens of buildings. Property managers shouldn’t have to project-manage their contractors, and on our jobs they don’t.
Quality across multiple elevations comes down to disciplined sequencing. Working in sections rather than treating the whole building at once gives the team the room to self-check each elevation and address touch-ups before moving on, rather than discovering inconsistencies only at the end of the job. The same controlled rhythm applies to the top-down window sequence on multi-level work.
Body corporate landscaping is a separate maintenance line item, and property managers worry about this for good reason. Our standard plant protection runs three rinse passes per section, before chemical, during dwell time, and after rinsing the walls. It’s the same protocol on every job. We treat the gardens like they belong to the same building we’re cleaning, because they do.
For body corporate insurance brokers and committee due diligence, $20 million public liability is the cover level approved contractors are expected to show. Certificate of currency available on request. We close every job with a walkthrough sign-off (or a video walkthrough for off-site decision-makers), and the work is backed by a free return visit if anything is missed and a money-back position if we genuinely can’t get it right.
Our process is built around three things: clear coordination with the building manager before we arrive, controlled section-by-section work on the day, and a proper sign-off afterwards.
After your inquiry comes through, we reply within one to five minutes during business hours and ask a short list of discovery questions: building type (body corporate, owner corporation, multi-unit), approximate footprint, number of levels, surface types (render, brick, weatherboards, metal cladding), age of the building, current condition, and whether exterior window cleaning is in scope. We then review the property remotely through Google Earth, Google Street View, and any listing photos available. For larger or more complex buildings, we ask the property manager to send a few photos of side elevations and access points.
From the discovery information, we put a custom quote together within 30 minutes to one hour of the inquiry, with pricing built around size, levels, surface type, condition, and accessibility. From there the timeline shifts to your committee. Approval cycles can run longer because of board meetings or AGM scheduling, and the quote sits ready until you’re ready to go.
Once the property manager or committee approves the quote, we lock in the agreed schedule and take a 50% deposit online with no credit card fees. Booking confirmation goes out immediately. This is also where we coordinate with the building manager: we agree on what they’ll communicate to residents, confirm access (locked car park gates, side passages, balcony access, internal courtyards), and identify any sensitive timber or seal issues we should know about before the day.
The building manager notifies residents of the service date in advance, usually through email, body corporate notice boards, or resident WhatsApp groups. Residents are asked to keep windows closed during the wash. We send a 24-hour reminder to the property manager so they have a final chance to remind residents and confirm any last-minute access arrangements.
We arrive on time, meet the building manager or designated contact, walk the perimeter to plan the most efficient sequence, and confirm scope. Then we set up: park for direct access, connect to your on-site water supply (our machine uses around 30 litres per minute, which is more than a 200-litre truck tank can supply across a full building wash), cover sensitive exterior electricals with plastic and tape, and for areas with pedestrian traffic, set up cones, tape, and crew direction where needed.
We typically work two sides at a time so the chemical never dries on the surface. For each section: rinse vegetation thoroughly, apply SH-based soft-wash detergent, allow it to dwell for 5 to 15 minutes depending on how dirty the building is, mid-rinse vegetation during dwell time, rinse the walls and eaves thoroughly, then final-rinse vegetation. Move to the next section and repeat. For heavily affected render, the section may run through the soap-dwell-rinse cycle two or three times before moving on. For metal cladding, the rinse stage is paired with water-fed pole agitation where needed.
For buildings with exterior window cleaning included in scope, we move to the windows after the building wash is complete. Top-level windows first using the water-fed pole and pure water system, middle-level windows next, ground-level windows last. The team scrubs frames, removes cobwebs, scrubs the glass, and rinses with pure water across every window. The top-down sequence keeps upper-level rinse water from landing on glass that’s already been cleaned.
The team does its own walkthrough first, looking for inconsistent sections, missed cobwebs, render that might need another pass, or runoff areas that need tidying, then completes touch-ups on the spot. After that, we walk the property manager through, or record a video walkthrough for off-site decision-makers so the committee can review the result. Anything spotted afterwards is addressed on a free return visit. The week after, our office team makes a happy call to confirm satisfaction, gather feedback, and ask for a Google review if appropriate.
Building washing is custom-quoted per property because body corporate and owner corporation buildings vary too widely for a published price range to be useful. Pricing depends on building size, number of levels, surface type, condition, accessibility, and whether exterior window cleaning is included. We send most quotes within 30 minutes to an hour of the inquiry.
A typical building washdown takes around one day. The exact timeline depends on building size, number of levels, surface type, and condition. Larger buildings, heavily affected render, or buildings with exterior window cleaning added to the scope can extend the timeframe.
The cleaning method is similar: the same soft-wash approach, the same SH-based chemistry, the same plant protection process, and the same top-down window sequence on multi-level work. The difference is coordination. Building washing requires liaising with the building manager, notifying residents, and managing access for shared properties.
Yes, body corporate and owner corporation buildings are a core part of our commercial work. We coordinate directly with the building manager or property manager, support resident notification through their normal communication channels, and structure the work around the building’s access constraints and resident expectations.
High-rise washing sits outside our service scope; we don’t use rope access or aerial-platform methods. Our service is built for accessible low-rise and mid-rise body corporate buildings, owner corporation properties, and multi-unit residential complexes.
We use soft washing, which is the same industrial machine configured for high water volume and low pressure, paired with SH-based detergent that breaks down mould, algae, and cobwebs. The chemistry does the lifting, not the pressure, so render and paint stay intact. For heavily affected render, we run two or three soap-dwell-rinse cycles until the surface comes back.
Yes, residents should be notified ahead of the service date and asked to keep windows closed during the wash. We coordinate this with your building manager during the booking process, and we send a 24-hour reminder so the property manager has a final opportunity to remind residents. Closed windows keep water out during exterior cleaning.
We record a video walkthrough showing the finished work, so the property manager can review the result themselves and share it with the committee or board. This is common for property managers covering multiple buildings, who get a clear visual record without scheduling another visit.
We use SH (sodium hypochlorite, also known as bleach), the industry-standard agent for breaking down mould, algae, and cobwebs on exterior surfaces. Dwell time runs 5 to 15 minutes depending on how dirty the building is, and we work in sections so the chemical never dries on the surface. We don’t make eco-friendly claims about it; we’d rather be honest about the chemistry than dress it up.
We bring all our own equipment: industrial pressure cleaner, soft-wash configuration, water-fed poles, hoses, ladders, pure water system, and harnesses for working at heights. We do require on-site water access because our machine uses around 30 litres per minute, which is more than a 200-litre truck tank can supply across a full building wash. The property manager only needs to confirm an outdoor tap connected to the building water supply.
Whether you’re organising a one-off building wash before an AGM, scoping maintenance for an upcoming committee meeting, or evaluating contractors for an owner corporation property going to tender, we can have a custom quote in your inbox within the hour, with no site visit needed for most buildings.
