A section of the glazing has clouded over and will not come clean. It has the look of frosting across one patch, with the rest of the panel unaffected. Should anyone have attacked it with a blade in the meantime, there will be scoring over the original damage.
This is acid etched graffiti. A corrosive gel has been left in contact with the pane for long enough to eat into it, and the surface it leaves behind is broken at a scale fine enough to scatter light instead of transmitting it. Nothing sits on the pane to be washed off. The glass is the damage.
We deal with the panel in place, normally completing the same day, with no screening and nothing to be manufactured first, at a small fraction of a replacement.

Here The Planning Unit Is The Week, Not The Day
St John's Wood is quiet for most of the year and then, several times a season, it is not. Major cricket brings crowds to this district in a way that differs from almost any other sporting calendar in London, and the difference matters practically.
A football fixture changes a district for an afternoon. A Test match changes it for five consecutive days. The roads around the ground carry restrictions for the whole of that period, the approaches from the station are busy from mid morning, and the high street and the surrounding hospitality run at capacity from breakfast through to evening across the entire week.
That produces an awkward coincidence for anybody with a damaged frontage.
Your busiest week is your least accessible week. The days when a clouded window costs you the most are exactly the days when getting a contractor, a vehicle and a working area to your door is hardest. If damage appears in the run up to a major fixture, it needs dealing with before the week starts rather than during it.
The lead time is longer than people assume. Booking the work for the day before play begins is cutting it fine. Two or three days ahead is comfortable, and on a village high street that is usually achievable if somebody picks up the phone when they see it rather than the following week.
And the quiet weeks are genuinely quiet. Outside those blocks this is a residential district with a village parade, easy access and no particular constraint, which is when most of our work here happens and when it is simplest to arrange.
Tell us where you are and what is coming up. It takes a minute and it is the difference between the frontage being right for your best week and being wrong all the way through it.

Frontages That Sit Behind A Gate
The second St John's Wood particular is how far back from the street a great deal of the glazing sits.
Beyond the high street this is a district of large detached villas, gated apartment blocks and premises set behind forecourts and in-and-out drives. The building line is well back from the pavement, often behind railings, a gate and a planted boundary.
Two things follow from that, and they pull in opposite directions.
The building itself is better protected. Glass that cannot be reached from the footway is glass that mostly does not get marked.
But the boundary takes the damage instead. Gates, entryphone panels, gate posts, nameplates and the glazing in a lodge or a porter's office are all at the pavement edge and all reachable. That is where we are most often called, and it is frequently reported as damage to the gate rather than as glass damage at all.
And a set-back frontage is unobserved. Where glazing behind a gate is marked, nobody walking past sees it, because nobody walking past can see the building properly. Damage on a set-back elevation is routinely found days or weeks later during a routine inspection rather than reported the morning after.
For managing agents and estate teams that is worth building into the inspection round: walk inside the boundary, not just along it.
Where We Get Called Out Around St John's Wood
St John's Wood High Street. The village parade, with independent food retail, cafes, pharmacies and clinics serving a close residential catchment, and the bulk of our high street work.
Circus Road and the streets off the parade. Smaller premises, professional offices and consulting rooms in converted stock, quiet once the working day ends.
Wellington Road and Grove End Road. Wide, heavily trafficked approaches with gated apartment blocks and set-back frontages behind them.
The area around the ground. Hospitality and retail that runs at capacity during major fixtures and comparatively quietly the rest of the time.
Abbey Road and the studio streets. A constant flow of visitors on an otherwise residential street, with frontages that are photographed far more than their owners realise.
Hamilton Terrace and Queen's Grove. Large villas in institutional, diplomatic and office use, with gates, lodges and boundary glazing.
Avenue Road and the northern approaches. Set-back premises behind long drives, where damage on the building is found late rather than reported early.
Painted Joinery, Gates And Boundary Ironwork
The stock here runs from stucco and brick villas to purpose-built blocks of several periods, and the older frontages carry painted timber joinery with glass bedded in putty and beads.
Replacing a pane in that kind of frontage disturbs beads, putty and paintwork, so the real cost includes a decorator as well as a glazier and the elevation looks patched until it is redecorated. Parts of the district also sit within conservation areas, and where a building is listed, altering it can require consent, with work carried out without that consent being an offence rather than a procedural matter.
The boundary ironwork is its own consideration. Gates, railings, gate posts and entryphone housings are painted or polished metal, and the same gel that clouds a pane will mark them. On a set-back property we are usually dealing with both, and it makes sense to quote them together rather than have two trades attend separately.
A restoration leaves the fabric alone entirely. Glass, rebate, putty, beads and paintwork are all as they were when we arrived, and nothing requires an application.
Replacing Or Restoring
| Fitting a new pane | Restoring the existing pane | |
|---|---|---|
| Timing against a busy week | Weeks of lead time, landing whenever it lands | Bookable ahead of the block, done in one visit |
| Access behind a gate | A crew and a vehicle inside the boundary for hours | One technician, in and out |
| Boundary ironwork | Gates and panels dealt with by a separate trade | Quoted and treated alongside the glass |
| Painted timber joinery | Beads, putty and paintwork disturbed | Joinery and paint untouched |
| Conservation area stock | Consent may be required | Nothing altered, nothing to apply for |
| Meanwhile | A boarded frontage on a village parade | Nothing covered at any stage |
| Cost | Glass, joinery, decoration and lost trade | Up to 90 per cent less |
The cost comparison is set out at glass replacement vs protection: the true cost, and the decision at should I replace or restore etched graffiti glass.

Three Kinds Of Damage
They look alike from a few paces and each takes a different route.
Paint or marker is a deposit on the surface. Opaque, sharply bounded, and a fingernail climbs onto it. The right solvent takes it away and leaves the pane intact.
Acid etching is within the surface. Clouded and pale while light still passes through, with a slight coarseness sitting level with the glass around it. The edge of it is soft rather than sharp, since the gel carried on spreading until it was stopped. Lit from within, it shows up considerably more than it does from outside.
Scratching is cut in physically. Hard bright scores from a blade, a stone or a key, deep enough for a fingernail to lodge in.
Compare yours with the images at glass scratching vs acid etching, and the milky effect is explained further at white frosty window graffiti. On what lies behind this kind of vandalism, there is why acid etching graffiti happens.
The First Hour
Any gel still present remains corrosive. It harms skin and eyes, so nobody handles it, and at a gated entrance that means keeping residents and visitors away from the gate rather than assuming word gets round.
Nothing sharp, nothing abrasive. Take a blade to it and you put permanent lines into a panel that could have been fully recovered, and running a cloth over wet gel moves the problem onto adjacent glass.
No metal polish on the gates or the entryphone panel. Working at a clouded plate with an abrasive polish hollows it locally and leaves a visible dished area. Leave it and photograph it.
Rinse with plenty of clean cold water where residue is visible and it is safe, gloved and with eye protection, allowing it to drain rather than spreading it about.
Photograph everything affected, dated, and walk inside the boundary while you do it. The gate is what you noticed; the building behind it may have been marked at the same time and nobody has looked.
Report it as criminal damage. The reference will be wanted before an insurer engages. There is a checklist of the right sequence at what to do when your shop window is vandalised.
How The Work Is Carried Out
Reading the frontage. Glass to begin with: its age, whether it is plain float, toughened, laminated, coated, mirrored or a sealed unit, and the depth the burn has reached. The boundary metalwork is then assessed on its own terms.
A concealed trial. The method is proved on a small section out of view before the rest is taken on.
Masking and containment. Beads, putty lines, paintwork, door furniture, gate ironwork and any signage are protected. Containment keeps everything within the working area and off the drive, the steps and the planting.
Through the abrasive grades. Each stage finer than the last, taking off a thickness of glass the eye cannot register, and running the treated zone well past the mark so it disappears rather than ending at a line. Keep it to the tag alone and a shallow lens is left sunk into the pane, bending everything seen through it.
Metalwork taken back evenly. Gates, plates and entryphone panels are worked across the whole face rather than locally, so the finish reads as one surface afterwards.
Cerium oxide on the glass to finish. The remaining haze comes out under wet cerium oxide, judged with light travelling through the pane rather than reflecting from it.
Checked from inside. A shop window or a hall window is looked through from within all day, so the finish is assessed from the room, against the light, before it is signed off.
A single pane is normally finished within three hours, with boundary metalwork worked alongside in the same attendance. The grinding stage is at acid etched graffiti techniques and removal methods, the polishing at how to polish shopfront glass to optical clarity, and the compound at how to use cerium oxide glass polish.
If a pane cannot be saved, that comes out at the assessment. An exceptionally deep burn, a unit that had lost its seal beforehand, or a coating across the surface we must abrade all mean the pane genuinely needs replacing, and we put that in writing before you commit.

What We Restore Around St John's Wood
- Polished and painted metal on gates, railings, entryphone panels, nameplates and door furniture.
- Float and older window glass in villa entrances, fanlights and sash windows.
- Laminated shopfront glazing on the High Street and Circus Road parades.
- Toughened glass in block entrance screens, lobby doors, porch glazing and balustrades.
- Lodge and gatehouse glazing at the boundary line.
- Sealed units in later windows, addressed from the street face only.
- Mirrors and mirrored panels in lobbies, lifts and shop interiors.
- Obscured and patterned glass on consulting rooms and clinics, rebuilt to the original finish.
- Glass block in basement areas and service elevations.
- Entrance steps and thresholds in polished granite or polished marble.
Nothing with a finished surface escapes the same gel, and on a gated property the boundary metalwork is hit far more often than the building behind it. Both are cleared in one attendance.
Who We Work For In St John's Wood
High Street traders. Independent food retail, cafes and pharmacies on the parade, worked around trading and ahead of the busy weeks.
Managing agents and block managers. Gated entrances, boundary ironwork and communal glazing, quoted together rather than split between trades.
Estate and facilities teams on set-back properties. Elevations behind a boundary, where the inspection round matters as much as the response time.
Clinics and consulting rooms. Privacy glazing rebuilt rather than cleared, with attendance timed around appointments.
Institutional and diplomatic premises. Access entirely on the occupier's terms, arranged in advance.
Who Carries The Cost
On a gated block the boundary, the gates, the entryphone and the communal glazing sit with the freeholder or the managing agent and are recovered through the service charge. An individual resident is not liable for the gate, which is worth knowing before anybody offers to sort it out themselves.
Along the parade the repairing covenant settles it. The shopfront itself is usually within your demise, whereas the shared entrance, the fanlight over it and the stair glazing usually are not. On converted villa stock that division is seldom self evident, so read the demise plan next to the covenant.
Run the numbers on insurance before a broker is contacted. Restoring one pane will generally come in under the excess, so a claim yields nothing and still leaves a mark on the policy. Where glass, gates and ironwork have all been done, the combined figure normally justifies it. Dated photographs of every affected surface and a written record of works are supplied whichever route you take.
Reducing The Chance Of A Repeat
Restoring the frontage deals with what has happened and nothing more. It discourages nobody, and a residential district that empties in the evening leaves a parade and a set of gates unobserved for most of the night.
Anti-graffiti film is a sacrificial layer fitted over the outer face of glazing so that it, rather than the pane, is destroyed next time, and it is stripped and renewed quickly at a small part of another restoration. On a shopfront it is straightforward. On period and listed stock it is cut to each pane rather than run across a frontage, and the specification is worth confirming with the local authority first.
It is worth being clear that it protects glass and not metalwork. A gate, a railing or an entryphone plate has no equivalent sacrificial layer, so on a gated property the realistic defence there is lighting, a camera covering the entrance, and dealing with damage promptly rather than letting it weather in.
There is a complete account at anti-acid etched graffiti protection, covering the principle of a layer designed to be sacrificed, how many years it lasts in service, the cost of installation and whether the glazing ends up looking different. Parade shopfronts are covered at protecting retail displays from glass vandalism.

St John's Wood Acid Etched Graffiti Removal: Frequently Asked Questions
Can the pane be restored or does it need replacing?
Restored, in nearly every case. The acid reaches only a fraction of a millimetre in, and the work takes that fraction off across the whole affected area and brings the clarity back. A new pane is needed only where the burn is exceptionally deep, the seal has already failed, or a coating lies across the surface we must abrade.
There is major cricket next week. Should we wait?
No, book it before. Those weeks are when a clouded frontage costs you most and when getting a contractor and a working area to your door is hardest. Two or three days ahead of play starting is comfortable; the day before is cutting it fine.
Our gates and entryphone panel have been marked, not the building.
That is the usual pattern on a set-back property, because the boundary is the only part anybody can reach. All of it is recoverable and we quote glass and metalwork together rather than leaving you to arrange two trades.
Should we polish the gate ourselves in the meantime?
Please do not. An abrasive metal polish worked at one spot hollows the plate locally and leaves a dished area on top of the original damage. Leave it, photograph it, and let it be taken back evenly.
Where else should we check?
Inside the boundary. A set-back elevation cannot be seen properly from the pavement, so damage on the building behind the gate is routinely found weeks later during an inspection rather than reported the next morning. Walk the drive, do not just look from the street.
Do we have to close or board up?
Neither. Nothing leaves the frame at any stage, so the frontage stays intact and a shop keeps trading throughout.
Our building is in a conservation area.
That argues for restoring. Consent can be required to alter a listed building, and the protection frequently covers the joinery and the opening as well as the elevation. Restoration alters none of it.
Our shopfront is painted timber.
Then a replacement pane means lifting beads, cutting out putty and making good the paint, which brings a decorator in alongside a glazier and leaves the elevation patched until it is redone.
Will the repair be visible?
It should not be. We carry the work far outside the damaged area and feather it away, so nothing marks where it ends. Bad finishes come from treating the tag in isolation, which leaves a shallow lens in the glass that bends the view through it.
There is scratching as well as etching.
One visit covers both. Etched and scored damage answer to an identical run of abrasives and the same finishing polish, with depth the sole limiting factor.
Our clinic has obscured glazing that has been etched.
It has to be rebuilt to the original finish rather than polished out, or you end up with a clear panel where a private one was. Those are assessed individually.
Can film protect the gates as well?
No. Film is for glazing. There is no sacrificial layer for a gate or an entryphone plate, so on a gated property the realistic defence is lighting, a camera on the entrance and prompt treatment before the damage weathers in.
As a resident, am I liable for the gate?
Almost certainly not. The boundary, the gates and the communal glazing sit with the freeholder or the managing agent and go through the service charge. Report it rather than arranging it yourself.
What does it cost?
Against a replacement, counting the glass, the joinery, the decoration and any metalwork, restoration comes in up to 90 per cent below. The figure depends on how many items are affected, the extent and depth, what each surface is, and the access. It is confirmed in writing beforehand. No lazy contractors. No hidden fees.
Should we claim on insurance?
Compare our figure with the excess first. One pane usually falls beneath it. Glass, gates and ironwork together usually do not.
How do we start?
Send photographs of everything marked, including the gate and the entryphone panel, and tell us whether anything major is on at the ground in the next fortnight. The photographs price it and the calendar decides when we come.
