Something has been sprayed on a Lewisham wall and you want it cleared properly, leaving the concrete, the brickwork and the paintwork as they were.
Almost all of it lifts. Two things here are different from the districts north of the river. A great deal of the marking is on blocks where the bill is shared rather than sent to one person, which changes who decides and how fast. And a great deal of the fabric is post-war concrete, which is far more absorbent than it looks and has a weak point most contractors walk straight across. The surface decides the method, and on a system-built elevation the joints between surfaces decide as much again.
We identify the material, prove the treatment out of sight, then lift the mark and leave the rest alone. Across SE13 and SE14 that is usually the same day, seven days a week.

On An Estate The Bill Is Shared
Most pages on this site address somebody who owns or occupies a building and pays for it directly. On a Lewisham estate that model does not describe what happens, and the difference matters if you are a leaseholder wondering why nothing moves.
The Council Is Three Things At Once
On a council block containing right to buy leaseholders alongside tenants, the local authority is simultaneously the freeholder, the managing landlord and the body you would otherwise report to. There is no separate agent to chase and no third party to appeal to, because all three roles sit in the same organisation.
What The Service Charge Actually Covers
Lewisham recharges leaseholders for a defined list of communal services: caretaking, building and estate repairs, sweeping and grounds maintenance, entry phones, lift servicing, shared window cleaning, communal lighting and heating, pest control and bulk waste. Costs are generally divided among the properties that benefit, and caretaking is explicitly linked to how much work a building needs, so the more the block requires the higher the cost to it.
Which Means Slow Cleaning Costs You Money
That last point is the one to act on. If communal cleaning scales with the work a block needs, a block marked repeatedly and cleared slowly is one whose leaseholders pay more every year through a charge they cannot opt out of. Reporting promptly is not civic-mindedness, it is the cheapest financial decision a leaseholder has, and far cheaper than a communal elevation that gets progressively harder to clean.
And The Fine Behind It All
For completeness, the borough does enforce. A fixed penalty notice for graffiti or flyposting is £265 if paid within ten days and £500 within fourteen, with a maximum court penalty running from £1,000 to unlimited, and there is no right of appeal against the notice itself. A report with a reference number is what makes any of that possible.
Post-War Concrete Drinks It
Lewisham was heavily rebuilt, and a large share of its walls are concrete rather than masonry. Almost everything people assume about concrete is wrong in the direction that causes damage.
What A System-Built Elevation Is
Precast panels delivered to site and bolted together, with the joints sealed rather than mortared. Board-marked in-situ concrete on the older blocks, the grain of the formwork still legible. Exposed aggregate panels where the finish is the stone itself. None of it behaves like brickwork, and none can be repointed if something goes wrong.
More Absorbent Than It Looks
Concrete reads as dense and impervious and is neither. The pore structure is open, exposed aggregate is open at the surface by design, and solvent-borne pigment sprayed on an untreated panel goes in rather than sitting on top. Which is why a tag left a fortnight on concrete is a different job from the same tag on glazed tile, and why the fast methods that appear to work take the top off the panel with the paint.
The Joint Between Panels Is The Weak Point
This is the detail most contractors miss. A system-built elevation is weathertight because of the mastic seal between panels, and on a block of that age the seal is often original and already hardened. It is not mortar, it cannot be raked out and replaced casually, and it is what stands between outside and inside. Play a pressure washer along a panel joint and water goes behind the facade rather than down it, which is water ingress inside somebody's flat rather than a mark outside. So the joints are masked and the work kept off them deliberately.
Which Rules Out Most Of The Quick Options
No pressure across joints. Nothing acidic, because the alkalinity of the concrete will react with it and the result is a bleached patch you cannot undo. No abrasive on exposed aggregate, because the finish is the aggregate. That leaves controlled chemistry with short dwell, poultices where the pigment has gone in, and patience, which is why a concrete elevation takes longer than the same area of brick.
Nothing At Full Strength Until A Hidden Square Proves It
On fabric this unforgiving the governing rule is that no product touches the visible wall until it has been proved somewhere it will not matter. The sequence is the same every time.

- Identify what the panel actually is, since precast, in-situ, exposed aggregate and rendered blockwork all read similarly from ten metres and behave differently.
- Find genuinely concealed test ground, which on an estate block usually means a return elevation, a bin store flank or the inside of an undercroft.
- Run the mildest credible option at reduced strength and reduced dwell.
- Read the result in daylight, wet and then dry, since concrete dries back much lighter than it looks when damp and a patch that seemed acceptable can be obvious an hour later.
- Escalate one step only where the previous step demonstrably fell short, and re-trial rather than applying the stronger option straight to the mark.
- Carry the proven setting onto the marked area with no adjustment on the fly, and keep it off the panel joints throughout.
Working that way also brings the difficult news forward. Where a panel has already been pressure washed by somebody else, or a mark has sat long enough to travel well into an untreated surface, full recovery genuinely needs more than cleaning, and we will say so at the quotation rather than after the invoice.
One Elevation, Four Materials
A typical Lewisham block presents several materials on one face, and a competent job treats each as a separate decision rather than working across them.
The main panels are concrete, absorbent and jointed as above. At ground level there is usually brick, either engineering brick that tolerates a great deal or soft stock that does not, and the two are hard to tell apart wet. Balcony and walkway edges carry painted metal balustrades, some factory finished and some repainted on site over decades, wanting opposite treatments. Entrance surrounds and bin stores are often rendered and painted, soft beneath the coating and easily bleached into ghosting. Door sets bring glazing, gaskets and powder coated frames, where the seals are more vulnerable than the glass. And on a refurbished block an insulated render system may sit over the original concrete, thin and easily punctured.
Substrate detail is on the relevant pages, including precast concrete panels, exposed aggregate concrete, unpainted brick, painted brick, smooth render, painted metal, powder coated metal, galvanised steel and laminated glazing.
What Superheated Steam Costs In Time
Low pressure superheated steam is the right tool on masonry here and the trade deserves stating plainly. It covers ground slowly, because heat needs dwell to soften a binder and there is almost no force behind the water to hurry it. Work that a jet would finish in twenty minutes takes a couple of hours. That time is the price of an intact brick face and full joints. On concrete it is used with more caution again, because a panel does not need much heat to take on water it will hold for days, and because the joints are exactly where a lance should not linger.
Where Nothing Else Is Gentle Enough
Dry ice earns its place on the surfaces where every alternative does harm. Painted balustrades and handrails, where an abrasive burnishes and a solvent lifts the coating. Entrance screens and door sets, where water near the gaskets is the risk rather than the glass. Exposed aggregate panels, where the pellets shock the film off without touching the stone. And communal interiors, stair cores and undercrofts, where nothing may be left on the floor for residents to walk through. It adds no water at all, which on a block where water finds its way into somebody's hallway is frequently the whole argument.
Porosity Decides Which Of The Three
| Surface | What it gets, and why |
|---|---|
| Non-porous: glazing, sealed metal, powder coated frames, glazed tile | A solvent gel, because nothing was absorbed: the film is softened where it sits and lifted away in minutes. |
| Porous: untreated concrete, exposed aggregate, soft brick, unpainted render | A poultice. The pigment has moved inward and has to be drawn back out over hours rather than pushed deeper. |
| Robust and painted: bin store doors, service gates, plant enclosures | Soda blasting, kept well away from panel joints, glazing and anything delicate within drift range. |
Anyone weighing one approach against another will find the reasoning in chemical solutions for graffiti removal, and anyone tempted by the fastest option should read pressure washing for graffiti removal first.
A Removal Contractor Against A Cleaning Company
- A cleaning company owns one system and uses it whatever the wall turns out to be. A removal contractor carries several and chooses after identifying the material.
- A cleaning company prices by area, because that is what its equipment measures. A removal contractor prices by elevation, because that is where the risk sits.
- A cleaning company needs a tap and a socket. We arrive self-contained with our own water and power, so no caretaker has to open anything.
- A cleaning company treats a trial patch as a delay. It is the only evidence a method is safe on a panel nobody can repair.
- A cleaning company supplies insurance details when asked. Public liability cover goes out before we attend.
- A cleaning company works weekdays and charges weekends as an exception. We work seven days a week, because that is when marking appears.
- A cleaning company wants somebody there to watch. Nobody needs to be on site, and the dated photographs do what supervision would.
How that is controlled in practice, from product selection to where run-off goes, is described under safety precautions during graffiti removal.
When Marking Actually Appears
On an estate the pattern differs from a high street and is worth scheduling around. Communal marking goes up mostly in the evening and early night, in places covered but not overlooked: stair cores, undercrofts, walkway returns, bin store surrounds, lift lobbies. Not the hours a shopfront is hit, and not surfaces anybody photographs.
Two things follow. The useful window is the working day rather than dawn or midnight, since residents are present overnight and communal areas are quietest mid-morning. And because the surfaces are internal or semi-internal, water and residue matter far more than outside, pushing the method towards dry ice and controlled gels rather than anything that runs. Saying on the first call whether the marking is outside or in a stair core changes what we bring.

What A First Attempt Does To The Job After It
The most expensive quotations we produce here are rarely for the worst graffiti. They are for ordinary marks somebody tried to deal with first, because on concrete the damage from the attempt is usually permanent while the tag never was.
A wire brush on a concrete panel takes the surface skin off with the paint and leaves an area rougher, lighter and more absorbent than everything around it, so the next mark goes deeper and cleans worse. A household solvent on an untreated panel drives pigment further in, turning a surface job into a staged poultice. Any strong remover near a panel joint attacks a mastic seal nobody can see. And painting over on a communal elevation commits the block to repainting that patch forever. None of it is anybody's fault, because none of it is obvious. The first ten minutes simply decide what the next two hours cost, so photograph it, report it and leave it alone. The reasoning is set out on DIY versus professional removal, and where the marked surface is not yours the routes are under reporting vandalism in London.
From Test Patch To Sign-Off
What happens between arriving and leaving is undramatic, and worth knowing so you can tell whether you got it. The extent is confirmed and the boundary between what goes and what stays agreed and photographed. Everything that is not the target is protected: glazing, balustrades, door sets, signage, and above all the panel joints. The trial patch is run concealed and read twice, wet and dry. The proven setting is carried onto the mark and worked outward from the edges so the treated zone blends rather than announcing itself. Run-off and residues are collected at source and removed under waste transfer documentation. Protection comes down in reverse with each surface checked. And the elevation is photographed and dated, with anything found that the building did not know about, such as a failed seal or an earlier repair, written down.
Removing It Against Painting Over It
| Painting over | Removing |
|---|---|
| On a communal elevation it commits the block to repainting that patch indefinitely, at everybody's cost. | Ends the job in one visit, with nothing recurring on the service charge. |
| Cannot be matched on concrete, exposed aggregate or weathered brick, so the patch ghosts against the wall around it. | Returns the elevation to one continuous surface. |
| Bridges panel joints and movement gaps that were designed to stay free. | Leaves the assembly working as it was built to. |
| Creates exactly the clean flat panel the next mark is looking for. | Leaves no invitation behind. |
Where We Are Called Out Around Lewisham
Lewisham High Street frontages, shutters and fascias. Lewisham Gateway and the station approaches. Rushey Green and the parades along it. Loampit Vale and Molesworth Street. Deptford Broadway and the New Cross Road corridor. Ladywell Road and Algernon Road. Estate blocks, stair cores, undercrofts and bin store surrounds throughout the borough. Railway and DLR structures where they meet private frontages. Plus service yards, loading bays and rear returns, which take most of the marking and receive the least attention.
Work Completed Across SE13 And SE14
We have lifted aerosol from precast concrete panels without opening the surface or touching the joints, cleared exposed aggregate with dry ice so the stone finish survived, removed marking from painted balustrades and walkway edges with the coating intact, treated stair cores and undercrofts with methods that left nothing on the floor for residents, cleaned shopfronts and shutters on the high street before opening, and corrected panels damaged by an earlier attempt with a brush. There is more on protected and older fabric under graffiti on historic buildings in London, while marking cut into glass rather than applied to it is dealt with on acid etched graffiti removal.
Who Instructs Us In Lewisham
| Who they are | What they need from us |
|---|---|
| Housing teams and estate managers | Methods safe on system-built panels and joints, priced so a service charge can absorb them. |
| Residents associations and leaseholder groups | Plain pricing for a body making a collective decision, and a record that stands up at the year end. |
| Managing agents for private blocks | One instruction across frontage, communal areas and service zones. |
| Independent shops and sole traders on the high street | A frontage cleared before opening, priced before attendance, with no contract to sign. |
| Schools, community buildings and places of worship | Straightforward pricing for an organisation with no property department behind it. |
Why A Photograph Beats A Description
We can give a firm figure from images in almost every case, because the three things that build a price are all visible and none are things a caller reliably reports.
First, what the wall is. A caller says concrete; the photograph shows exposed aggregate, a different method, or an insulated render system applied over the concrete during a refurbishment, different again. Second, the true extent: a mark described as a metre across regularly runs over two panels and a joint, and the joint decides the approach. Third, position, since a stair core, a third floor walkway and a ground level flank are three jobs with identical marking. Send the elevation, the mark in context and the surface close up, and the contingency comes out of the price. Managing agents comparing tenders will find factors that affect the cost of graffiti removal the most useful; anyone setting a budget wants how much graffiti removal costs in London; and anyone minded to leave it should read the hidden costs of not removing graffiti promptly.
The Trader With Nobody To Escalate To
The estate position above has one virtue: somebody is responsible and a mechanism exists. An independent shop on Lewisham High Street or Deptford Broadway has the opposite problem. No property department, an agent acting for the building rather than the occupier, and a freeholder who may take a fortnight while the mark sits on a frontage that trades on how it looks.
Three things make it manageable. Find out where your demise stops before anything else, since retail leases here commonly end at the shopfront and shutter and hand everything above to the freeholder, so the fascia may never have been your bill. Get a written quotation either way, because a figure on paper is what moves a landlord from sympathy to authorisation. And look at your excess before calling it an insurance matter, since one frontage almost always sits inside it. Who is responsible for graffiti removal sets out the tests, and whether insurance covers graffiti removal in London covers the rest.
Coating As A Budgeting Decision
Coatings get discussed as deterrents and they deter nobody. Nobody choosing a wall at night can tell a treated surface from an untreated one. A coating changes the cost of the next removal, which makes it arithmetic rather than security, and on an estate that arithmetic is easy because the incidents are already recorded somewhere.
Count how often a surface is actually marked, from the repairs log rather than impression. Multiply by what a removal costs. Compare against the coating and its reapplication interval, remembering a sacrificial system is consumed at each incident and a permanent one degrades quietly over years. On a bin store surround or stair core dado hit several times a year it pays for itself and reduces the communal charge. On a main elevation marked once in three years it never does, and on exposed aggregate the appearance change is a cost on top. If you are deciding which surfaces across a block or a portfolio are worth treating, how anti-graffiti coatings work explains the two types and the best coating products for London properties covers specification.

Lewisham Graffiti Removal: Frequently Asked Questions
We are leaseholders. Who pays for the communal wall?
Everybody in the block, through the service charge. Communal repairs and caretaking are recharged across the properties that benefit rather than billed to one flat.
So is there any point reporting it quickly?
Yes, and it is financial rather than civic. Caretaking cost is linked to how much work a building needs, so a block marked repeatedly and cleared slowly costs its leaseholders more.
Can you pressure wash our concrete panels?
No. It takes the surface skin off along with the paint, and along a panel joint it drives water behind the facade rather than down it.
What is wrong with cleaning across the joints?
The joint is a mastic seal, not mortar, and on a block of that age it is usually original and hardened. Damage it and you have created a water ingress problem inside a flat.
Is concrete not too hard to absorb paint?
It looks that way and it is not. The pore structure is open, so a solvent-borne pigment goes in rather than sitting on the surface, especially on exposed aggregate.
How soon can you attend SE13?
Same day for most morning calls at ground level. Walkway or upper level positions become booked visits once access has to be arranged.
Does anybody need to let you in?
Not for external work. We carry our own water and power. Stair cores and undercrofts need access arranging, which is worth doing on the first call.
The marking is in the stair core rather than outside.
Then it changes the method rather than the price band. Inside we use approaches that leave nothing on the floor and add no water, which usually means dry ice or a controlled gel.
Somebody scrubbed a panel with a brush first.
Then tell us, because it changes what is achievable. A brushed panel is rougher, lighter and more absorbent than its neighbours, and that part is not reversible by cleaning.
Is the fine for graffiti real?
Yes. The borough issues fixed penalty notices of £265 within ten days or £500 within fourteen, with court penalties from £1,000 upward, and no appeal against the notice.
Should we just paint the communal wall instead?
It is the expensive option disguised as the cheap one, because the block then repaints that patch indefinitely and the cost sits on the service charge forever.
The tag has been there a month.
On concrete that matters more than elsewhere, because the pigment has had time to move in. It is usually a poultice across more than one visit by then.
Would a coating reduce our service charge?
On a surface that is genuinely hit several times a year, such as a bin store or a stair core dado, yes. On a main elevation marked rarely, no.
Our glass has been scratched or etched.
Etching and scoring bite into the glass itself, which puts them outside what any remover can reach. They are handled separately, on the acid etched graffiti removal page.
What do you need to quote?
The elevation, the mark in context and the surface close up, plus whether it crosses a panel joint. That last one changes the method more than the size of the mark does.
