A section of the glazing has clouded and will not come clean however it is treated. The rest of the panel is untouched while that one area looks frosted. Where somebody has since applied a blade, there is scoring sitting over the top of the original mark.
This is acid etched graffiti. A corrosive gel has been left against the panel long enough to eat into it, and the surface that remains is broken at a scale fine enough to scatter light instead of transmitting it. There is nothing sitting on the glass to wash away. The panel itself has been damaged.
We treat the pane in position, normally within a day, with nothing screened off and no unit on order, at a small share of what replacing it would cost.

The Bigger The Pane, The Stronger The Case
Stratford carries some of the largest single panes of glass in London. Mall frontages several metres across, concourse glazing, arena and venue entrances, full-height screens at the base of the towers. And the thing worth understanding about oversized glass is that the cost of replacing it does not rise in proportion to its size. It rises much faster.
Restoration, by contrast, is priced on the area actually damaged. A tag on a four metre pane costs very much the same to take out as the same tag on a shop window.
That gap is the whole argument on this kind of glazing, and it comes from four separate places.
An oversized unit cannot be carried in. It arrives on a vehicle that has to get close, and it is placed with lifting equipment rather than by hand. On a mall frontage or a concourse that means planning, exclusion zones and frequently an overnight possession.
Getting the old one out is its own operation. Large panes are often set into structural framing with adjacent panels that have to come out first, or fixings that were installed before the surrounding finishes existed. What looks like one pane is regularly a sequence of them.
Lead times are long and the unit is bespoke. Oversized glazing is made to order, frequently laminated and frequently coated, so there is nothing to pull off a shelf. Meanwhile the frontage stands damaged, or worse, hoarded.
And the disruption lands on everybody. A replacement on a busy mall or concourse affects trading, circulation and neighbouring units. A restoration is one technician working within a small bounded area for a few hours.
So when somebody quotes you to replace a large pane because of a mark measuring a few hundred millimetres, ask what the restoration figure is first. On glazing this size, the difference is not a percentage. It is a different order of decision entirely.

Two Centres, Two Completely Different Questions
Stratford holds a premium destination centre and an older local one within a few minutes of each other, and the damage that lands on them is identical while the reason for dealing with it is not.
In the premium centre it is a brand problem. Tenants pay for a standard of presentation and expect it maintained. A clouded panel on a flagship frontage undermines the proposition regardless of what it costs to fix, so the questions we get asked are about how quickly it can be done, whether it can happen out of hours, and whether the finish will genuinely be invisible against the panels either side.
In the older centre it is a cost problem. Budgets are tighter, the units are smaller and independent, and the honest question is whether it is worth spending anything at all. There the answer that matters is that restoration costs a fraction of replacement, needs no closure and can often be done in a single visit for less than the excess on the policy.
Both are legitimate and we answer them differently rather than giving the same pitch twice. What does not change is the method, the documentation and the willingness to say when a panel genuinely cannot be saved.
Where We Get Called Out Around Stratford
The shopping centres. External frontages, mall entrances and unit glazing across both, with the buying positions described above.
The station and interchange. Concourse and approach glazing, with concentrated flow through most of the day and a narrow quiet window.
Broadway and The Grove. The older High Street run, with independent retail, food businesses and flats above.
The park and venue frontages. Large-format glazing and entrance screens on buildings around the open space, exposed on several sides.
East Village and the newer blocks. Ground floor commercial units beneath residential development, with specified modern glazing.
Angel Lane and the streets off the centre. Smaller premises and service frontages, quiet at night and overlooked by very little.
Rear and service elevations. Delivery routes and back-of-house glazing, where damage regularly goes unnoticed for weeks.
What Large-Format Glazing Actually Is
Before any price is given on a big pane, the make-up has to be established, because oversized glazing is rarely plain.
It is usually laminated, for safety at that size. It may be a sealed unit with low emissivity or solar control, and on mall and concourse frontages it is frequently treated to cut reflection so the interior reads properly from outside. It may carry applied manifestation. Every one of those is a coating or an interlayer, and each changes what can be done.
Abrading into a coating destroys it, and on a repeating run of identical panels the result is one panel reading differently in colour and reflectivity from all its neighbours. From across a mall or a concourse that is worse than the original mark and considerably more expensive to put right.
So we identify the panel first, ask for the facade documentation where the building is recent enough to have it, and say plainly if a panel should be left alone. On glazing of this value that conversation happens before anybody commits to anything.
Replacing Or Restoring
| Fitting a new pane | Restoring the existing pane | |
|---|---|---|
| Oversized glazing | Lifting equipment, exclusion zone, possession | One technician in a small bounded area |
| Cost basis | Rises sharply with the size of the unit | Priced on the damaged area, not the pane |
| Removing the old panel | Adjacent panels and fixings frequently involved | Nothing is unfixed at any stage |
| Coated and laminated units | Bespoke, made to order, long lead time | Unit and its treatments retained |
| Disruption | Trading, circulation and neighbouring units | A few hours, contained |
| Timescale | Weeks for a specified oversized unit | Usually the same working day |
| Cost | The unit, the access, the closure | 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.

Telling The Three Apart
They resemble each other from a distance and each takes a different route.
Paint or marker is a layer sitting on the glass. Opaque, cleanly bounded, and a fingernail climbs over it. Solvent removes it and the pane beneath is sound.
Acid etching is within the surface. Pale and clouded while light still comes through, with a faint grittiness level with the glass rather than raised on it. It has no clean edge, because the gel went on travelling until something stopped it. On a large pane it is far more obvious from a distance than people expect, because the eye reads a dull patch against a big flat reflective surface immediately.
Scratching is cut in. Sharp glinting lines from a blade, a stone or a key, which a fingernail lodges in.
There are photographs set against each other at glass scratching vs acid etching, and the washed out look is examined in white frosty window graffiti. The motivation is covered at why acid etching graffiti happens.
The First Hour
Residue may still be live. The gel burns skin and eyes, so the affected section needs cordoning rather than staff simply being told, particularly where the public passes within reach of it.
Nothing sharp, nothing abrasive. A blade puts permanent scoring into glazing that was entirely recoverable, and wiping wet gel simply extends the damage to panels that were clean.
No graffiti remover on treated glazing. There is no coating for it to break down, and on an anti-reflective or solar control panel it creates a second problem on top of the first.
Flood it with cold water if there is visible residue you can safely get to, gloved and with eye protection, allowing it to run clear rather than working it across the panel.
Photograph the panel whole, not just the mark. On large-format glazing we need to see the full panel and its neighbours to price it properly and to judge how the finish will need to read against the run.
Find the facade documentation if the building is recent. It answers the specification question faster than anything else and saves a survey visit.
Report it as criminal damage. The reference will be wanted before an insurer engages. The steps in order are at what to do when your shop window is vandalised.
How The Restoration Is Done
Establishing the panel. Laminated, toughened, coated, anti-reflective, mirrored or a sealed unit, whether manifestation is applied and to which face, and how far the acid has travelled. On the newer buildings the facade paperwork settles it quickest.
Access and timing agreed first. On a mall, a concourse or a venue frontage the working window, the extent of the bounded area and any out-of-hours arrangement are settled before a date is confirmed.
Depth reading, then a trial patch. We verify the method somewhere it will not be seen before taking on the full panel.
Masking and containment. Framing, gaskets, seals, manifestation and signage are protected, and the slurry is contained and kept off a floor finish that people will be walking on within the hour.
Down through the abrasive grades. Stepping from coarse grades to fine, we take off a thickness of glass no eye can resolve, carrying the treated zone well past the damage so that it ends without any perceptible edge. Confined to the tag alone, the work leaves a shallow lens that warps everything behind it, and over a large flat panel that distortion carries right across the space.
Cerium oxide to finish. Remaining cloudiness is worked out wet under cerium oxide, and we judge it standing where daylight passes through the panel rather than reflects from it.
Judged against the run. The treated panel is compared with the untreated panels either side, straight on and at an oblique angle, because on repeating large-format glazing the neighbours are the only standard that matters.
One panel typically takes three hours, with access arrangements adding to the attendance rather than the work. The abrasive work, the clarity stage and the compound each have their own guide: acid etched graffiti techniques and removal methods, how to polish shopfront glass to optical clarity and acid etched graffiti removal equipment and materials.
If a panel is past saving you hear so at assessment, never later. An unusually deep burn, a unit that had already lost its seal, or a coating across the surface we must abrade each mean the panel genuinely needs replacing, and that goes to you in writing before you commit.

What We Restore Around Stratford
- Large-format and oversized panels in mall, concourse and venue frontages.
- Laminated and security rated glazing in entrance screens, lobbies and unit frontages.
- Toughened glass in balustrades, walkway screens, automatic doors and shelters.
- Float and older window glass in the Broadway parades and the storeys above.
- Curtain walling and infill panels at ground and podium level.
- Sealed double glazed units, treated on the external leaf only.
- Mirrors and mirrored panels in retail interiors, lift cars and washrooms.

Any finished surface is open to the same gel, and on a large entrance the framing and the handrails are marked as readily as the glazing. All of it is dealt with in one attendance.
Who We Work For In Stratford
Centre and asset management. Large-format frontages and mall glazing, restored out of hours with the finish judged against the adjoining run.
Retail and hospitality tenants. Unit frontages worked around trading, with documentation suitable for a landlord or a head office.
Venue and arena operators. Entrance screens and concourse glazing, scheduled around the event calendar rather than through it.
Independent traders on Broadway. Smaller frontages priced so that dealing with the damage is a realistic decision.
Managing agents of the newer blocks. Street level units and shared entrance screens, with the glazing make-up confirmed before any price is quoted.
Who Carries The Cost
On a leased unit it comes down to the repairing covenant. Your own frontage normally sits inside the demise, while the mall glazing, the communal entrance and anything forming part of the envelope belong to the landlord and are recovered through the service charge. In a managed centre that line sits further out than most occupiers expect, so it is worth checking rather than assuming you are liable for a panel that was never yours.
On large-format glazing the same question carries more weight, simply because the sums involved are larger. A tenant asked to fund a replacement oversized unit should establish two things before agreeing to anything: whether the panel is actually within their demise, and whether restoration has been priced at all.
Insurance wants a quick sum before anybody is notified. A single restored panel regularly comes in below the excess, meaning the claim yields nothing and still shows at renewal. Where several large panels are involved, or where access forms a real part of the cost, the calculation changes. Dated photographs and a written account of the works come with every job.
Making It Less Likely To Recur
Restoring the panel deals with what has happened and nothing further. It deters nobody, and long runs of accessible ground floor glazing around open public space will be found again.
Anti-graffiti film is a sacrificial layer fitted over the outer face so that it, and not the panel, is destroyed next time, and swapping it over is quick work at a fraction of another restoration.
On large-format glazing the argument is stronger than the raw figures suggest, because the thing you are protecting against is not only the restoration cost. It is the possibility of damage deep enough to force a replacement, which on an oversized bespoke unit is the outcome nobody wants. A film takes that risk off the table for the panels within reach.
Where glazing is coated, anti-reflective or carries manifestation, the product has to be matched so that clarity and colour rendering are unaffected. That is worth a proper specification conversation rather than fitting whatever is available.
The full picture sits at anti-acid etched graffiti protection, taking in the logic of an expendable surface, how long a fitted film serves, what installing it comes to and whether the glazing reads any differently. Shopfront glass has its own page at protecting retail displays from glass vandalism.

Stratford Acid Etched Graffiti Removal: Frequently Asked Questions
We have been quoted to replace a very large pane. Is that necessary?
Ask for the restoration figure before agreeing to anything. On oversized glazing the cost of replacing rises far faster than the size of the panel, while restoration is priced on the damaged area. A tag on a four metre pane costs much the same to take out as the same tag on a shop window.
Why is replacing a big panel so much more involved?
Because it cannot be carried in. It arrives by vehicle, is placed with lifting equipment, and getting the old one out frequently means removing adjacent panels or fixings installed before the surrounding finishes existed. Then there is the lead time on a bespoke unit.
Can you work in the mall during trading?
Usually out of hours is better, and that is arranged with centre management before a date is set, along with the extent of the bounded area. The work itself is one technician in a small space for a few hours.
Our glazing is anti-reflective or coated.
Then it depends where the treatment sits relative to the damage. Abrading into a coating destroys it and leaves that panel reading differently from all its neighbours, which across a repeating run is worse than the original mark. We establish the make-up before quoting.
Can the panel be restored or does it need replacing?
Restored, in the great majority of cases. The acid has bitten no further than a sliver of the surface, and the job takes that sliver back evenly before polishing the panel to full transparency. Replacement is forced only by an exceptionally deep burn, a failed seal, or a coating in the path of the work.
Will the treated panel match the ones either side?
That is the standard we work to, and we check it straight on and at an oblique angle before signing off. On repeating large-format glazing the neighbouring panels are the only meaningful comparison.
Will the repair be visible?
It should not. We extend the treatment a long way beyond the mark and thin it out, leaving nothing to show where it finishes. Restricting it to the tag sinks a shallow lens into the glass which distorts the view through it, and across a big flat panel that reads from a considerable distance.
Do we need to hoard the frontage?
No. At no point does a panel come out, so the frontage is never breached and there is nothing to screen.
Several panels along one elevation are affected.
Priced panel by panel, with the attendance charged once. Where the run cannot be finished in a single window we sequence it and prioritise the panels facing the main approach.
There is scratching as well as etching.
Both come out together. The same graded abrasion followed by the same polish handles scoring exactly as it handles etching, and only the depth of the damage sets a limit.
What about the framing and the handrails?
Marked as often as the glazing on a large entrance, and both recoverable. Metalwork and stone are handled alongside the glass.
We are a tenant and the landlord says it is ours.
Check the demise plan before agreeing, particularly on a large panel. In a managed centre the boundary sits further out than most occupiers expect, and mall glazing and communal entrances are usually the landlord's.
Is protective film worth it on glazing this size?
More than usual. What you are insuring against is not only the next restoration but the chance of damage deep enough to force a replacement, which on a bespoke oversized unit is the outcome to avoid. On coated or anti-reflective panels the film has to be matched properly.
Should we claim on insurance?
Do the sum first. One restored panel usually falls under the excess. Several large panels, or a job where access is a real part of the cost, usually do not.
What does it cost?
A long way below a replacement, and confirmed in writing before anything begins. The number reflects how much of the panel is affected, how deep the burn goes, the specification and the access arrangements. No lazy contractors. No hidden fees.
How do we get a price?
Photograph the whole panel and its neighbours rather than just the mark, add one from inside, and send the facade documentation if the building is recent enough to have it. That is usually enough to price the work without a survey visit.
