Somebody has left a pale, clouded mark in the glass and it will not come off. It looks as though a patch of the pane has been frosted on purpose. Nothing your housekeeping team owns touches it, and whoever tried a blade has left scratches sitting on top of the original damage.
The mark is acid etched graffiti. A corrosive gel was applied to the pane and left long enough to dissolve the surface, pitting the glass finely enough that it scatters light rather than passing it. There is nothing resting on the surface to be cleaned away.
We take it back out where it stands. Normally within the same day, with nothing boarded, nothing on order, and at a small share of what a replacement would cost.

The Only Window You Have Is Between Checkout And Check In
Bayswater and the streets around Lancaster Gate hold one of the densest concentrations of hotel and guest accommodation in London, most of it in converted stucco terraces. That density shapes the whole job, and it produces a scheduling problem that no shop or office has.
A hotel never closes. There is no shutter, no last orders and no quiet Sunday. Guests arrive off long flights at four in the morning, leave for early departures before six, and come and go continuously in between. The idea of working when nobody is around simply does not apply.
What does exist is a lull, and it is narrow. Between the end of checkout and the start of afternoon arrivals there is a period when the entrance is quieter than at any other point in the day, housekeeping is upstairs rather than at the door, and reception is not handling a queue. That is when we work on hotel frontages here, and we plan around it rather than asking you to accommodate us at a worse moment.
The stakes are different too. On a shop, a damaged window costs you passing trade. On a hotel it is the first thing every arriving guest sees, at exactly the moment they are forming a judgement about whether the place is well run. Frontages get photographed. Photographs end up attached to reviews, and a review mentioning a vandalised entrance outlives the damage by years.
That is why we treat this as urgent work rather than maintenance, and why we photograph the frontage before and after as standard, so you have a dated record of how quickly it was dealt with if anybody ever raises it.

The Glass Below Pavement Level
The second Bayswater specific is the one nobody looks at.
These stucco terraces were built with basement areas, so behind the railings and below the pavement there is another set of glazing entirely. Lower ground windows, staff entrances, storage and plant rooms, kitchen and back of house glazing in the hotels, and in many buildings the lightwell serving a basement flat or office.
Nobody checks it. It sits below eye level, behind railings, out of the sightline of anyone at the front desk or behind a counter. We are regularly called to a marked entrance door and find, once we look over the railing, that the lower ground glazing was done at the same time and has been sitting damaged for weeks.
So when you report a frontage here, look down before you call. It costs nothing, it usually adds panes to the same attendance rather than to a second one, and it stops you paying twice for the same trip.
Where We Get Called Out Around Bayswater
Queensway. The main retail run, with a mix of independent shops, restaurants and visitor trade, and frontages tight to a pavement that stays busy well into the evening.
Lancaster Gate and the streets facing the park. Hotel frontages in long stucco terraces, with entrance doors, porches and basement areas below the railings.
Porchester Road and Bishop's Bridge Road. Mixed commercial frontage on busy through routes, less overlooked after dark than Queensway.
Westbourne Grove at the Bayswater end. Independent retail and restaurants, with older shopfronts set into terrace stock.
Moscow Road and Craven Road. Smaller hotels, guest houses and the businesses serving them, on quieter streets where damage is usually found by night staff.
Craven Terrace and the mews behind. Converted stabling and small premises, unobserved at night and rarely passed by anyone with a reason to look.
The station approaches at Bayswater and Queensway. Short stretches carrying concentrated pedestrian flow, where the frontages nearest the entrances take the most exposure.
Stucco, Railings And Painted Joinery
The building stock here is terrace rather than purpose built commercial, and that changes the replacement arithmetic considerably.
Entrance doors and ground floor windows sit in painted timber joinery, often original or built to match, with the glass bedded in putty and beads rather than held in a modern gasket. Replacing a pane disturbs the beads, the putty and the paintwork, so the true cost carries a decorator alongside a glazier, and the frontage will not look right again until that whole elevation is redecorated.
A good deal of this stock also sits within conservation areas. Where a building is listed, altering it can require consent and doing the work without that consent is an offence rather than a technicality, and the protection frequently extends to the joinery and the opening as much as to the elevation.
Restoration leaves the lot alone. Putty undisturbed, beads untouched, paint unmarked, nothing removed from the opening and no application to make.
Replacing It Against Restoring It
| Fitting new glass | Restoring what is there | |
|---|---|---|
| Hotel operating hours | An open entrance for hours, guests arriving throughout | Contained, inside the midday lull |
| Painted timber joinery | Beads, putty and paintwork all disturbed | Joinery and paint untouched |
| Trades required | Glazier and decorator | One technician |
| Lower ground and lightwell glazing | Awkward access, small awkward panes, full price each | Treated in the same attendance as the frontage |
| Conservation area stock | Consent may be required | Nothing altered, nothing to apply for |
| Meanwhile | Boarded, and it is the first thing guests see | Nothing covered at any point |
| Cost | Glass, joinery, decoration and lost bookings | Up to 90 per cent less |
The cost comparison is set out at glass replacement vs protection: the true cost, and the choice between the two at should I replace or restore etched graffiti glass.

Working Out Which Damage You Have
Three kinds of damage look alike from the pavement and each needs a different answer.
Paint or marker rests on the glass. Dense colour, a clean edge, and a fingernail climbs onto it where it begins. Solvent removes it and the pane beneath is sound.
Acid etching is in the glass. Pale and clouded yet still translucent, with a faint chalkiness sitting level with the surrounding surface rather than raised above it. The outline softens where the gel travelled before somebody wiped at it. Seen from a lit reception looking out, it is considerably more obvious than from the street.
Scratching is mechanical. Thin, bright, deliberate lines from a blade, a stone or a key, and a fingernail settles into them.
There are photographs to compare yours against at glass scratching vs acid etching, and the clouded look is explained at white frosty window graffiti. For the wider picture across the city, read the rise of acid-etch vandalism in London.
What Night Staff Should Do When They Find It
Anything still wet is a live chemical. Etching gel injures skin and eyes. Nobody handles it, and on a hotel entrance that means keeping arriving guests away from it rather than simply telling reception.
No blades, no scouring pads. A scraper leaves permanent scoring in glass that would have recovered completely, and drawing a cloth across wet gel carries the damage onto panes that were untouched.
No proprietary removers. There is nothing for them to dissolve and they add an unknown chemical to painted joinery as well as to the glass.
Where residue is visible and it is safe, flush it with cold water, gloved and with eye protection, letting it run off rather than wiping across the pane.
Photograph it before anything else, dated, from outside and from the lobby. Then look over the railings and photograph the lower ground glazing as well, because that is where the rest of it usually is.
Log it with the police as criminal damage. Insurers will ask for that reference before they take anything further. There is a short guide to the whole sequence at what to do when your shop window is vandalised.
How The Restoration Is Carried Out
Establishing the pane. Older or modern, float, toughened, laminated, coated, mirrored or a sealed unit, and how deep the acid has travelled. On terrace frontages the glass is frequently older than people assume.
A trial patch out of sight. The method is proved on a small section nobody looks at before the full pane is committed to.
Masking the joinery. Beads, putty lines, paintwork, door furniture, signage and any applied vinyl are protected before a tool touches the glass. On a painted frontage the joinery is the element that cannot easily be put back. Slurry is contained and kept off the steps, the tiling and the railings.
Working down through the grades. Each abrasive stage finer than the one before, lifting a depth of glass no eye could measure, with the treated area carried well beyond the mark so it fades rather than ending at a line. Work the lettering alone and what remains is a dished patch, a shallow lens in the pane, bending everything behind it. In an entrance door that distortion is at eye level for every guest walking through.
Cerium oxide to finish. The last of the haze is taken back under wet cerium oxide, judged by looking through the pane towards the light rather than at what reflects off it.
Checked from the lobby. An entrance door is looked through far more often than it is looked at, so the finish is assessed from inside, against the light, before we call it done.
Reckon on three hours for one pane. We have written the process up in detail across three pieces: acid etched graffiti techniques and removal methods for the removal itself, how to polish shopfront glass to optical clarity for the final stage, and how to use cerium oxide glass polish for the compound.
Where restoration is not going to work you hear it at the start. Acid that has reached unusually deep, a sealed unit whose seal had already failed, or a coating sitting where the abrasive has to run each mean the pane genuinely needs replacing, and that is put in writing before anything is agreed.

What We Restore Around Bayswater
- Float and older window glass in terrace entrance doors, ground floor windows and fanlights.
- Laminated shopfront glazing on the Queensway and Westbourne Grove frontages.
- Toughened glass in hotel entrance doors, porch screens, revolving door surrounds and balustrades.
- Lower ground and lightwell glazing behind the railings, including staff and service entrances.
- Double glazed units in later openings, treated externally so the cavity is never breached.
- Mirrors and mirrored panels in lobbies, lifts, bars and bathrooms.
- Obscured, etched and decorative glass, where an existing pattern has to be reproduced rather than removed.
- Glass block in basement areas, lightwells and rear elevations.
- Entrance steps, thresholds and facings in polished granite and polished marble.
- Polished metal on door furniture, name plates, bell panels, railings and canopy fittings.
Anything with a worked surface is vulnerable to the same gel. On a hotel frontage the brass name plate, the bell panel and the railings are marked as readily as the door glass, and all of it is handled on one visit.
Who We Work For Around Bayswater
Hotels and guest accommodation. Entrance, lobby and lower ground glazing restored inside the midday lull, with a dated record of how fast it was dealt with.
Restaurants and bars serving the visitor trade. Worked between service periods rather than before opening.
Independent retail on Queensway. Display frontages restored without covering the window or emptying it.
Managing agents and residential landlords. Terrace conversions where the communal entrance, the fanlight and the lightwell glazing sit outside any occupier's demise.
Serviced apartment and short let operators. Frontages that have to present properly at every hour, restored without disrupting arrivals.
Who Carries The Cost
The lease decides it, and on a converted terrace there is usually more than one interest in the building. The repairing covenant will tell you whether your own frontage falls inside the demise. The communal entrance door, the fanlight above it, the stair window and the lightwell glazing serving a basement unit generally belong to the landlord and are recovered through the service charge. Read the demise plan alongside the wording, because on this kind of stock the boundary is rarely obvious.
On insurance, weigh our figure against the excess before notifying anybody, since a single restored pane frequently falls beneath it and a claim producing nothing still registers at renewal. Once the lower ground glazing and the communal panes are in the count, the total usually justifies a claim. Dated photographs from both faces and a written works description come with the job either way.
Keeping It From Happening Again
Restoring the pane deals with what is in front of you. It deters nobody, and a frontage on a street with this much night movement is likely to be found again.
A sacrificial film bonds to the outer face and is built to be ruined instead of the glass. It peels off and is renewed in minutes at a small share of another restoration, and it is optically clear so an entrance or a display looks exactly as it does now. On terrace stock it is cut to each pane rather than applied as a sheet, and on a listed or conservation area frontage the specification is worth agreeing with whoever oversees the building before it goes on. It is also worth extending to the lightwell glazing, since that is the glass nobody is watching.
The subject is covered at anti-acid etched graffiti protection, including the principle it works on, how long it stays serviceable, what fitting costs and its effect on appearance. For display frontages, see protecting retail displays from glass vandalism.

Bayswater Acid Etched Graffiti Removal: Frequently Asked Questions
Can the pane be saved or do we need new glass?
Saved, in nearly every case. The acid has reached only a fraction of a millimetre into the surface, so the work removes that depth evenly across the affected zone and polishes the clarity back. Replacement is only forced where the etch has gone unusually deep, the unit had already failed, or a coating lies in the path of the work.
We are a hotel and never close. When can you actually come?
In the lull between the end of checkout and the start of afternoon arrivals. It is narrow but it is real, and it is the point in the day when the entrance is quietest and reception is not handling a queue. We plan around it rather than asking you to find us a better moment.
Will guests see the work happening?
Very little of it. The working area is small and contained, we are not lifting anything out of a frame, and a single pane is typically finished within three hours. Replacing the glass would mean an open entrance for considerably longer.
Should we check anywhere other than the front door?
Yes, and specifically below the railings. Lower ground and lightwell glazing gets marked at the same time and nobody looks at it, so we frequently find it already damaged when we attend for something else. Adding it to the same visit costs far less than a second attendance later.
Our entrance is painted timber. Does that complicate things?
It makes no difference to us, and it is a good reason not to replace. Putting a new pane in means lifting beads, cutting out putty and making good the paint, so you are hiring two trades and still looking at a mismatch until the whole elevation is done again. We protect the joinery and work only on the glass.
Our building is in a conservation area.
That points firmly towards restoring. Consent can be needed to alter a listed building, and the joinery and the opening are often protected as much as the elevation. Restoration changes none of it.
Will the repair be visible to somebody walking in?
It should not be. The work is carried well past the mark and faded out so there is no edge to catch the eye. The failure to avoid is polishing the tag alone, which leaves a shallow lens in the pane, and in an entrance door that sits at eye level for everyone passing through it.
There is scratching as well as etching.
Both come out in the same visit, since the graded abrasion and polish that lifts an etch also takes back a scratch. Depth is the constraint, and very occasionally a cut has gone too far to recover.
What about the brass name plate and the bell panel?
Marked as often as the glass on a hotel frontage, and both recoverable. Polished metal, stone steps and railings are dealt with alongside the windows.
Can you treat toughened, laminated and sealed units?
All three, yes. The gel only ever reaches the exterior face, so a double glazed unit keeps its cavity and its seal intact throughout. Toughened, laminated and sealed glazing each need handling differently, which is the reason we establish the make up of the pane before starting.
Our lobby has obscured glazing that has been etched.
It has to be matched rather than polished away, otherwise you end up with a clear panel where an obscured one was. Decorative and privacy glazing is assessed individually for that reason.
What does it cost?
Price a replacement honestly, including the glass, the joinery, the decoration and the bookings affected while the entrance is open to the street, and restoration comes in up to 90 per cent below. Our figure moves with the area affected, the depth, what the pane is, the access and whether film follows. It is confirmed in writing first. No lazy contractors. No hidden fees.
Is it worth claiming on insurance?
Compare our figure with your excess before notifying anyone. One pane usually falls beneath it. Add the lightwell and communal glazing and it usually does not.
The damage has been there a while. Still treatable?
Almost always. Age makes the work slower because weathering settles into the pitting and more has to be taken back, but the pane still clears.
Can you look after several properties for us?
Yes. One contact regardless of how many addresses, identical reporting for each, and consolidated invoicing.
How do we get a price?
Send photographs from outside and from the lobby, and one over the railings of the lower ground glazing. Between them we can usually identify the damage, price the whole job and tell you which lull we would aim for.
