A milky, clouded patch has turned up in the glass and nothing will shift it. It has the look of frosting applied to one part of the pane. If a blade has already been used on it, there will be scratches lying across the top of the original mark.
The damage is acid etched graffiti. A corrosive gel was spread on the pane and left to dissolve the surface, pitting it finely enough to scatter light rather than pass it through. There is nothing sitting on the glass waiting to be cleaned off, which is why nothing has worked.
We take it out of the pane where it stands. Normally within the day, with nothing boarded and nothing on order, at a small share of what replacement costs.

The Bridge Changes What Same Day Actually Means
Any contractor quoting a Hammersmith job off a map is going to get their timings wrong, and it is worth being straight with you about why.
Hammersmith Bridge has been closed to motor traffic for years. On a map the south bank sits a few hundred metres away. In practice, while the bridge remains shut to vehicles, a van coming from Barnes, Castelnau or the Putney side has to go round via Chiswick Bridge or Putney Bridge, and at the wrong hour that detour is substantial.
Two things follow, and both matter more than they sound.
We route from the north. Our attendance here comes across the A4 corridor rather than up from the south bank, which is how we hold a same day response for W6 rather than promising one we would miss. If somebody has quoted you a time that assumes a straight run across the river, ask them how.
Your frontage is watched differently than it used to be. The closure changed movement patterns through this part of Hammersmith. Streets that used to carry steady cross river traffic now carry less of it, particularly in the evening, and a frontage that once sat on a busy through route may now be considerably less overlooked after dark than its owner assumes. Several of the jobs we attend on the streets nearest the bridge fit exactly that pattern.
None of that is a reason to worry. It is a reason to be realistic about how long your glass sits unobserved at night, and to think about protection accordingly.

Glazing That Faces A Bus Station, Not A Street
The second Hammersmith particular is the Broadway, and it is unusual enough to be worth its own section.
A substantial amount of retail and food glazing here does not face a street at all. It faces inward, onto an enclosed interchange concourse with the bus station beneath and the gyratory wrapped around the outside. That environment behaves differently from a shopfront on King Street in three ways we plan for.
The air is dirtier than it looks. An enclosed bay handling buses all day deposits a fine film on nearby glazing, and like any grime it masks light etching. Damage on interchange frontages is frequently found later than damage on the street.
There is no real closing time. Services run early and late, so the concourse is rarely empty in the way a shopping parade is. The workable window is set by the transport operator's quiet period rather than by your own trading hours.
Access is not yours to grant. Working on a frontage inside an interchange means arrangements with whoever manages that environment, not simply with the unit. We ask who that is at the quotation stage rather than turning up and finding out.
Where We Get Called Out Around Hammersmith
King Street. The long retail spine and the bulk of our work here, with independent shops, chains and food businesses along a route carrying heavy traffic and pedestrians throughout the day.
The Broadway and the interchange. Retail and food frontages facing the concourse, with the conditions described above.
Lyric Square and the streets behind it. Theatre, hospitality and market pitches around the square, busy in bursts and quiet between them.
Shepherd's Bush Road and Glenthorne Road. Mixed commercial frontage on busy connecting routes, less overlooked once the offices empty.
Fulham Palace Road. A long southward run with retail, hospitality and medical premises, exposed to constant through traffic.
Queen Caroline Street and the approaches to the bridge. The streets most affected by the change in cross river movement, and noticeably quieter after dark than they used to be.
Lower Mall and Upper Mall. Riverside pubs and premises fronting the towpath, reached on foot with no vehicle access at the door.
Period Parades And Modern Blocks Side By Side
The building stock changes character within a few hundred metres here, and the right approach changes with it.
Along King Street and the older parades the glazing frequently sits in painted timber, bedded in putty and beads. Replacing a pane disturbs the beads, the putty and the paintwork, which brings a decorator in alongside a glazier and leaves the frontage looking patched until that elevation is redecorated. Parts of the district also carry conservation area protection, and where a building is listed, altering it can require consent, with works done without that consent being an offence rather than a formality.
Around the Broadway and the office blocks the glazing is modern and often specified rather than ordinary, carrying low emissivity, solar control or anti-reflective coatings. Abrading through a coating destroys it and leaves a panel reading differently in colour and reflectivity from the ones beside it.
Both point the same way for different reasons. Restoration alters nothing, so on protected fabric no application arises and on specified glazing the unit keeps its performance. What matters is identifying which you have, and that comes before we price anything.
Replacing Or Restoring
| Fitting a new pane | Restoring the existing pane | |
|---|---|---|
| Getting materials to site | A vehicle and a delivery, with the river crossing detour | One technician, kit carried in |
| Interchange frontages | Manoeuvring a pane through a managed concourse | Worked in place inside the quiet period |
| Painted timber parades | Beads, putty and paintwork disturbed | Joinery and paint untouched |
| Coated and specified glazing | Specification has to be reproduced exactly | Unit and its performance retained |
| Timescale | Days to weeks once measured and ordered | Usually the same day |
| Meanwhile | Boarded, on a high street that lives on appearance | Nothing covered at any stage |
| Cost | The glass, the fitting, the making good and lost trade | Up to 90 per cent less |
The cost side is set out at glass replacement vs protection: the true cost, and the decision at should I replace or restore etched graffiti glass.

Working Out What You Have
Three sorts of damage look similar from a distance and each takes a different route.
Paint or marker lies on top of the glass. Solid colour, a defined boundary, and a fingernail rides up where it begins. The correct solvent takes it off cleanly.
Acid etching is in the glass. Pale and clouded but still translucent, with a faint chalkiness sitting level with the surface instead of standing above it. The outline fades where the gel travelled before somebody wiped at it. With the interior lit it reads far more strongly than from the pavement.
Scratching has been cut in. Thin bright furrows made with a blade, a stone or a key, and a fingernail runs into one and stops.
Photographs to compare yours against are at glass scratching vs acid etching, with the clouded appearance covered at white frosty window graffiti. There is background on how widespread this has become in the rise of acid-etch vandalism in London.
The First Hour
Anything still wet is a live chemical. Etching gel injures skin and eyes. Keep staff and the public away from it, and on an interchange frontage tell the management team as well as your own people.
Nothing sharp, nothing abrasive. A scraper leaves permanent scoring in glass that would have recovered fully, and wiping wet gel carries the damage sideways onto panes that were untouched.
No proprietary removers. There is nothing for them to dissolve, and on coated or filmed glazing they introduce a second problem.
If residue is visible and it is safe, flush it with cold water in quantity, gloved and with eye protection, letting it carry away rather than dragging a cloth through it.
Photograph it at once, dated, from both faces. On a frontage that carries a film of grime, clean a small area beside the damage first, because the contrast is what shows the real extent.
Report it as criminal damage. An insurer will want the reference before engaging. The order of things is set out at what to do when your shop window is vandalised.
How The Work Is Done
Reading the pane. Period or modern, float, toughened, laminated, coated, mirrored or a sealed unit, whether film is present and on which face, and how far the acid has travelled. On a street where the stock changes every few doors this is established rather than assumed.
Depth assessment and a trial patch. The method is proved on a small area out of view before the full pane is committed to.
Masking and containment. Beads, putty lines, paintwork, frames, seals, vinyl and signage are protected. Slurry is contained, and on an interchange frontage the working area is bounded so nothing wet reaches a surface people are crossing.
Down through the abrasive grades. Each stage finer than the last, taking off a depth of glass no eye could measure, with the treated zone carried well past the mark so it fades instead of ending at a line. Work the tag alone and a dished patch is left behind, a shallow lens in the pane, bending everything seen through it. On a large shopfront that shows from across the road.
Cerium oxide to finish. The last of the haze comes back under wet cerium oxide, judged by looking through the pane towards the light rather than at what reflects off it.
Checked from both faces. From the pavement, from inside against the interior lighting, and at an oblique angle, because on a busy road people see your glass sideways long before they see it square on.
A single pane is normally finished within three hours. The removal is documented at acid etched graffiti techniques and removal methods, the finishing at how to polish shopfront glass to optical clarity, and the equipment at acid etched graffiti removal equipment and materials.
And where restoration will not work, that is said at the assessment rather than discovered later. Acid that has gone unusually deep, a sealed unit whose seal had already failed, or a coating sitting where the abrasive must run each mean the pane genuinely needs replacing, and the opinion is given in writing before anything is committed.

What We Restore Around Hammersmith
- Laminated shopfront glazing on King Street and the Broadway frontages.
- Float and older window glass in the period parades and upper storey glazing.
- Toughened glass in entrance doors, concourse screens, balustrades and shelters.
- Interchange and concourse glazing facing the bus station rather than the street.
- Sealed units in modern frontages, worked externally with the cavity closed.
- Mirrors and mirrored panels in restaurants, salons and shop interiors.
- Obscured and patterned glass, including privacy glazing on medical premises, matched rather than removed.
- Glass block in older commercial frontages and lightwells.
- Steps, cills and plinths in polished granite and polished marble.
- Polished metal on door furniture, handrails, frames and shutter housings.
The gel attacks any worked surface. On a parade the handrail and the letter plate are marked as readily as the display glass, and the whole frontage is dealt with in one visit.
Who We Work For In Hammersmith
Retail and food operators on King Street. The bulk of our work here, scheduled around trading rather than around us.
Interchange and concourse units. Frontages inside the managed environment, worked in the operator's quiet period with access agreed in advance.
Office and building managers around the Broadway. Ground floor and reception glazing restored outside core hours.
Riverside pubs and premises on the Mall. Towpath frontages reached on foot, with no vehicle needed at the door.
Managing agents and residential landlords. Parade frontages with flats above, where the communal door, fanlight and stair window sit outside any occupier's demise.
Who Carries The Cost
The lease settles it. The repairing covenant tells you whether the shopfront falls inside your demise, which along King Street and Fulham Palace Road it usually does. The communal entrance, the fanlight and the stair window serving flats above generally belong to the landlord and are recovered through the service charge. On the larger Broadway buildings the boundary often sits further out than expected, so the demise plan is worth reading alongside the wording.
For a unit inside the interchange the position is different again, because the fabric may belong to the operator rather than to any tenant. Establish that before anybody pays for anything.
On insurance, weigh our figure against the excess before notifying. A single restored pane will frequently fall beneath it and a claim producing nothing still registers at renewal. Several panes or a whole frontage usually justifies claiming. Dated photographs from both faces and a written works description come with the job regardless.
Reducing The Chance Of A Repeat
Restoring the pane deals with the damage you can see. It deters nobody, and on the streets nearest the bridge, where evening movement is thinner than it once was, a frontage can sit unobserved for a long stretch of the night.
Sacrificial film bonds to the outer face and is built to be ruined instead of the glass, stripping off and being renewed in minutes at a small share of another restoration. It is optically clear, so a display or an entrance looks no different. On coated and specified glazing the film has to be chosen so that clarity and colour rendering survive, and on painted timber frontages it is cut to each pane rather than applied as a sheet.
There is a full account at anti-acid etched graffiti protection, taking in the mechanism behind it, how long a fitted film lasts, what fitting it costs and what it does to the appearance of a window. There is separate guidance for shop displays at protecting retail displays from glass vandalism.

Hammersmith Acid Etched Graffiti Removal: Frequently Asked Questions
Can the pane be restored or do we need new glass?
Restored, in nearly every case. The acid has reached only a fraction of a millimetre into the surface, so the work takes that depth off evenly and polishes the clarity back. New glass is needed only where the etch has gone unusually deep, the unit had already failed, or a coating sits in the path of the work.
Can you really get here the same day?
Yes, because we route from the north rather than across the river. With the bridge shut to motor traffic, anybody coming from the Barnes or Putney side faces a long detour, and a quoted time that assumes a straight run across is a time that will be missed.
Our unit faces the bus station rather than the street. Can you work there?
Yes, with access arranged through whoever manages that environment rather than through the unit alone. We ask who that is when we quote, and we work in the operator's quiet period rather than assuming your trading hours apply.
Why did nobody notice the damage sooner?
Because the glass on the interchange and on the main road frontages carries a film of grime that hides light etching. It is frequently found when the glass is next cleaned rather than when it happened.
Is our frontage more exposed than it used to be?
On the streets nearest the bridge, quite possibly. Evening movement through there is thinner than before the closure, so glass that once sat on a busy through route may now be unobserved for longer stretches of the night.
Do we need to close or board up?
Neither. The pane never leaves the frame, so there is nothing to cover and no reason to stop trading.
Our shopfront is painted timber. Does that matter?
Not to us, and it is a good argument against replacing. New glass means lifting beads, cutting out putty and making good the paint, so two trades are involved and the frontage looks patched until the elevation is redecorated.
Our glazing is coated. Is restoration safe on it?
That depends which face carries the coating relative to the damage. Abrading into a coating destroys it and leaves that panel reading differently from its neighbours. The make up is confirmed first and we will say plainly when a panel should be left alone.
Will the treated area show afterwards?
It should not. The treatment runs well beyond the damage and thins away, so nothing marks where it finishes. The mistake to avoid is a contractor working the tag on its own, which sinks a shallow lens into the pane and warps whatever is behind it.
There is scratching as well as etching.
One visit deals with both, because the sequence that lifts an etch is the sequence that lifts a scratch. Depth is the only real constraint.
What about the handrail and the door furniture?
Marked as often as the glass on a frontage like this, and both recoverable. Polished metal and stone are handled alongside the windows.
We are on the towpath at Lower Mall with no vehicle access.
That suits restoration and rules out replacement for most practical purposes. We walk in with the kit rather than trying to bring a pane along a shared path.
What does it cost?
Against replacing the same glazing, counting the unit, the fitting, the making good and the trade lost while boarded, restoration comes in up to 90 per cent below. The price turns on the area affected, the depth, what the glass is, the access and whether film follows. It is confirmed in writing beforehand. No lazy contractors. No hidden fees.
Should we claim on insurance?
Hold our figure against the excess first. One restored pane commonly costs less than the excess itself, in which case notifying achieves nothing and still shows at renewal.
It has been there for a while. Still fixable?
Almost always. Age lengthens the job because weathering settles into the pitting and more has to be taken back, but the pane still clears.
How do we get it priced?
Send a photograph from outside and one from inside with the lights on. If the glass is dirty, wipe a patch beside the damage first, because the contrast is what shows us the real extent.
