A clouded patch has appeared in the glass and nothing lifts it. The effect is of frosting applied to one area and nowhere else. Where a blade has already been tried there will be scoring across the top of the original mark.
The damage is acid etched graffiti. A corrosive gel was applied to the pane and left to dissolve the surface, pitting it so finely that it scatters light rather than passing it through. Nothing remains on top to be cleaned off. The surface itself has been altered.
We take it back out where it stands, generally within the day, with nothing boarded and nothing on order, for a small share of what replacement would cost.

On The Medical Streets The Plaques Get Hit Too
The frontages along Harley Street, Wimpole Street, Devonshire Place and the streets around them are unlike anything else in London, and the thing that makes them distinctive is also the thing most often damaged alongside the glass.
A consulting house here carries a column of polished brass nameplates beside the door, sometimes a dozen of them, each belonging to a different practitioner. They are the frontage. They are what a patient looks at while waiting to be let in, and they are what the address signals about the building.
Acid gel attacks polished brass exactly as it attacks glass. It dulls the surface, eats into the lettering and leaves a bloom that no amount of metal polish will shift, because the damage is in the metal rather than on it. We are called to marked glazing here and find the plaques done at the same time more often than not.
Do not let anybody polish it. A cleaner working at a clouded plaque with an abrasive metal polish will make the situation considerably worse, because the damage needs taking back evenly across the whole face rather than rubbing at locally. That is how a plaque ends up with a visibly hollowed patch around the lettering.
Engraved lettering needs care. The infill in engraved brass is a different material from the plate around it, and treating the two as one surface is how lettering gets lost. Plaques are assessed individually and we will say plainly where a plate is beyond recovering and should be remade.
Quote the whole frontage, not just the window. Glass, plaques, letter plate, bell panel and the step. It is usually one incident and it should be one attendance, not three visits by three trades.

Nobody In The Building Owns The Front Door
The second Marylebone particular is a governance problem that catches out anyone trying to get the work instructed.
A consulting house is rarely occupied by one practice. It is far more common for a building to hold rooms let by the session to a dozen or more independent practitioners, each in on different days, each with their own plaque and none of them holding a lease of the building. They are users of rooms rather than tenants of the frontage.
So when the entrance is marked, the person who notices it has no authority to fix it and frequently does not know who does.
The building manager is the right first call. Most houses on these streets have one, whether employed by the building or by the practice group that runs it, and that is the person who can obtain a quotation and instruct the work.
Above them sits the estate. Much of this district is held on long established estate ownership, and on frontage matters the estate's requirements may apply to what can be done. A restoration does not alter anything, which is precisely why it rarely raises a question where a replacement would.
And the plaques may be individually owned. A practitioner usually owns their own plate even though they hold no interest in the building. Where several are damaged we itemise per plate so each can be dealt with by whoever is responsible for it, without anybody having to unpick a single figure.
If you are a practitioner who has noticed it, call us anyway. A written, itemised figure is the fastest way to get a building manager moving.
Sessions, Not Opening Hours
Consulting rooms run on sessions rather than trading hours, and that changes when work can realistically happen.
A building may be quiet at eleven in the morning and full at two. Lists run in blocks, patients arrive and leave in waves, and a waiting room that is empty on Tuesday is at capacity on Thursday. The genuinely reliable window on these streets is early, before the first list of the day, and we plan around that rather than assuming a shop pattern applies.
Where a building has treatment or procedure rooms at ground floor level, we ask before attending rather than after. Noise, vibration and a working area outside a window are all things a clinical list can do without, and none of it is difficult to schedule around if the question is asked in advance.
Where We Get Called Out Around Marylebone
Harley Street and Wimpole Street. The consulting houses, with brass plaque frontages, railings and lower ground glazing, and the occupancy position described above.
Marylebone High Street. The principal retail run, with independent shops, restaurants and cafes in period stock and a trade that depends on how the street looks.
Marylebone Lane and Moxon Street. Narrow streets with small independent frontages, quiet once the shops close and overlooked by very little.
Chiltern Street and Paddington Street. Boutique retail, restaurants and hospitality in red brick stock, with display glazing at a small scale.
Wigmore Street and Cavendish Square. Larger commercial and institutional frontages, professional premises and the offices between them.
Baker Street and Portland Place. Wide, heavily trafficked routes with long ground floor elevations and institutional buildings.
Seymour Place and the western streets. Mixed commercial frontage and converted premises where damage frequently goes unnoticed for days.
Georgian Frontages And What Replacement Means
The consulting houses and much of the surrounding stock are Georgian, with painted timber joinery, glass bedded in putty and beads, and a great deal of railing and gate ironwork at the front.
Replacing a pane disturbs beads, putty and paintwork, so the real cost carries a decorator alongside a glazier and the elevation looks patched until it is redone. A good deal of this stock also sits within conservation areas or carries a listing, and where a building is listed, altering it can require consent, with works carried out without that consent being an offence rather than a procedural matter. The protection routinely extends to the joinery and the opening as much as the elevation.
Restoration disturbs none of it. The pane stays in its rebate, putty and beads are untouched, the paint is unmarked and nothing needs applying for.
Replacing Or Restoring
| Fitting a new pane | Restoring the existing pane | |
|---|---|---|
| Authorisation | A larger sum, needing building manager and possibly estate sign off | A figure a building manager can obtain and instruct |
| Brass plaques | Plates remade and re-engraved | Taken back evenly across the face, lettering preserved |
| Clinical sessions | Days of disruption at the entrance | One early window before the first list |
| Painted Georgian joinery | Beads, putty and paintwork disturbed | Joinery and paint untouched |
| Listed and conservation stock | Consent may be required | Nothing altered, nothing to apply for |
| Timescale | Weeks once approval and glazing are arranged | Usually a single visit |
| Cost | Glass, joinery, decoration, plates and making good | 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.

Which Of The Three Is On The Pane
Three sorts of damage look alike from a few feet and each needs a different answer.
Paint or marker lies above the surface. Dense colour, a hard boundary, and a fingernail rides up where it begins. Solvent removes it and the glass beneath is unharmed.
Acid etching is within the surface. Washed out and hazy while still passing light, with a faint grittiness at the same level as the glass around it. The mark tails off where the gel ran before anyone reached it. From a lit consulting room or hallway looking out, it reads far more strongly than from the pavement.
Scratching is a physical cut. Thin, glinting lines left by a blade, a stone or a key, and your fingernail drops in and catches.
Comparison photographs can be found at glass scratching vs acid etching, and the washed out look is discussed at white frosty window graffiti. Why anyone does this in the first place is examined at why acid etching graffiti happens.
What To Do Before We Arrive
Residue left on the surface is still chemically active. The gel harms skin and eyes, so it is not something to touch, and at a consulting house entrance arriving patients need keeping clear of it rather than reception merely being told.
Keep blades and abrasive pads away from the glass, and metal polish away from the plaques. Both make the job harder and more expensive, and on a plate the polish leaves a hollow that was not there before.
Proprietary removers will not help. There is nothing lying on the surface for them to break down, and on painted joinery or engraved brass they can cause harm of their own.
Where residue is visible and it is safe, flood it off with cold water, gloved and with eye protection, letting it drain rather than wiping across the surface.
Photograph everything marked, dated, from outside and inside, and include a close shot of each plaque. The plate photographs are what let us tell you which can be recovered and which should be remade.
Report it as criminal damage. The reference will be wanted before an insurer engages. There is a step by step on reporting at what to do when your shop window is vandalised.
How The Work Is Carried Out
Reading the frontage. The glass first, whether original or replacement, plain float, toughened, laminated, coated, mirrored or a sealed unit, and how deep the acid has gone. Then the metalwork, since plates, letter plate and bell panel each need assessing on their own.
A trial out of sight. The approach is proved on a small area nobody sees before the rest is taken on.
Protecting the frontage. Everything around the pane is covered before work starts: the beads and putty lines, the paintwork, the door furniture, the railings and any signage. Containment holds the whole operation inside the working area, keeping it off the step and out of the area below.
Through the abrasive grades. Each stage finer than the last, taking off a depth of glass no eye could measure, and carrying the treated area well past the mark so it fades rather than ending at a line. Confine it to the tag and a shallow lens is left sunk into the pane, distorting the room behind it.
Plates taken back across the whole face. Brass is worked evenly rather than locally, so the plate reads as one surface afterwards and the lettering is preserved rather than softened.
Cerium oxide on the glass to finish. Any haze still present is worked out under wet cerium oxide, judged with light travelling through the pane rather than reflecting from it.
Assessed from inside. A consulting house window is looked through from within all day, so the glass is judged from the room, against the light, before it is signed off.
A single pane is normally finished within three hours, with plaques worked alongside in the same attendance. The abrasive stage is described in acid etched graffiti techniques and removal methods, the finishing in how to polish shopfront glass to optical clarity, and the polish in how to use cerium oxide glass polish.
Where restoration will not work you hear it at the assessment. A burn that has gone unusually far down, a unit whose seal had already failed, a coating occupying the surface the abrasive must cross, or a plate etched through the engraving each mean the item genuinely needs replacing, and that view is put in writing before anything is committed.

Who We Work For In Marylebone
Building managers on the consulting streets. Whole frontages quoted in one document, glass and metalwork together, ready to instruct.
Individual practitioners. Plates itemised separately so each can be dealt with by whoever owns it.
Clinics and treatment premises. Privacy glazing recreated rather than cleared, with attendance arranged around the session timetable.
Independent retail and hospitality. Marylebone High Street, Marylebone Lane and Chiltern Street, worked around trading.
Estate and managing agents. Period portfolios where restoration avoids the consent question a replacement would raise.
Who Carries The Cost
On a consulting house it is rarely the person who noticed. The entrance door, its glazing, the railings and the fabric of the building sit with whoever holds the building, whether that is a practice group, a landlord or the estate above them, and the cost is met accordingly. An individual practitioner's plate is usually their own.
On the retail parades the repairing covenant decides. Your own shopfront normally falls inside the demise, while the communal entrance, fanlight and stair glazing generally do not. Read the demise plan alongside the wording, because on converted Georgian stock the boundary is seldom obvious.
On insurance, weigh our figure against the excess before notifying a broker. A single restored pane will often fall beneath it, and a claim producing nothing still appears at renewal. A frontage with glass, plates and ironwork all affected usually justifies a claim. Dated photographs of everything marked and a written works description come with the job regardless.
Reducing The Chance Of A Repeat
Restoring the frontage deals with what has happened and nothing further. A consulting street is empty and unobserved for most of the night, and a frontage found once tends to be found again.
Anti-graffiti film is a sacrificial layer fitted over the outer face of the glass so that it, rather than the pane, is destroyed next time, and it is removed and renewed quickly at a small part of another restoration. On period and listed stock it is cut to each pane rather than run across a frontage, and where a building is listed the specification is worth confirming with the local authority before fitting.
It is worth saying that film protects glass and not brass. There is no equivalent sacrificial layer for a nameplate, so on these streets the realistic defence for the plaques is lighting, a camera covering the entrance, and dealing with damage quickly rather than letting it weather.
You can read the full account on anti-acid etched graffiti protection, which sets out the reasoning behind a sacrificial layer, how many years one holds up, installation pricing and what it does to the look of a window. High street frontages are dealt with in protecting retail displays from glass vandalism.

Marylebone Acid Etched Graffiti Removal: Frequently Asked Questions
Our brass plaques have gone cloudy. Can they be saved?
Usually, yes. The damage is in the metal rather than on it, so it has to be taken back evenly across the whole face rather than rubbed at locally. Where an etch has gone through the engraving the plate should be remade, and we will tell you which is which before anything is touched.
Our cleaner has been polishing it. Does that matter?
It makes it harder. Abrasive metal polish worked at one area hollows the plate around the lettering, so you end up with a visible dished patch on top of the original problem. Ask them to leave it and photograph it instead.
Who should instruct the work on a consulting house?
The building manager. Practitioners here generally use rooms by the session rather than holding a lease, so the person who notices the damage usually has no authority over the frontage. Call us for a figure anyway, because a written quotation is the fastest way to get the building manager moving.
Several plaques are damaged and they belong to different people.
We itemise per plate so each practitioner can deal with their own, while the glass and the communal metalwork are quoted to whoever holds the building. One attendance, several lines, no unpicking required.
When can you attend?
Early, before the first list of the day, is the reliable window on these streets. Sessions run in blocks rather than continuously, so a building that is quiet at eleven may be full at two.
We have treatment rooms at ground floor level.
Tell us before we attend and we will schedule around the list. Noise, vibration and a working area outside a window are all avoidable with notice, and none of it is difficult to plan for.
Can the glass be restored or does it need replacing?
Restored, in nearly every case. The acid has damaged a sliver of the surface far thinner than the eye can register, and the work removes that sliver across the affected area and brings the clarity back. Replacement is forced only by an exceptionally deep burn, a failed seal, or a coating sitting in the path of the work.
Our building is listed.
That argues for restoring rather than replacing. Consent can be required to alter a listed building and here the protection often covers the joinery and the opening as well as the elevation. Restoration alters none of it.
The consulting room glazing is obscured.
Then it has to be matched rather than polished away, or you are left with a clear window where a private one was. Those panes are assessed individually.
Do we need to close the entrance?
No. Nothing comes out of the frame at any point and the door stays in use throughout.
Will the repair show?
It should not. The treatment is carried well beyond the damage and thinned away, so no boundary is left. A poor finish comes from abrading the tag alone, which sinks a shallow lens into the pane and distorts the room behind it.
There is scratching as well as etching.
Both come out on one visit, because a scratch responds to the same sequence of abrasives and polish as an etch does. The depth of the worst of it is the one thing that limits us.
Can film protect the plaques as well as the glass?
No, and it is worth being straight about that. Film is for glazing. There is no equivalent sacrificial layer for a nameplate, so the realistic defence there is lighting, a camera on the entrance, and dealing with damage before it weathers.
What does it cost?
Against a replacement, which on this stock means glass, joinery, decoration, remade plates and making good, restoration comes in up to 90 per cent below. The figure depends on how many items are affected, the extent and depth, what each one 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. A single pane usually falls beneath it. A frontage with glass, plates and ironwork all marked usually does not.
How should we start?
Send photographs of everything affected, including a close shot of each plaque, and tell us who manages the building. The photographs let us price it and tell you which plates are recoverable, and knowing the manager means the quotation reaches the right desk straight away.
