A milky patch has appeared in the glass and nothing shifts it. It looks as though part of the pane has been frosted on purpose. If someone has already attacked it with a blade there will be scoring sitting over the original damage.
The damage is acid etched graffiti. A corrosive gel was spread across the pane and left to eat into the surface, pitting it so finely that it throws light about instead of letting it through. Nothing is sitting on top to be cleaned off. The glass itself is what has changed.
We take it back out where it stands, usually within the day, with nothing boarded and nothing on order, for a small share of what replacing the pane would cost.

The Porter Is The Fastest Route To Getting It Fixed
Maida Vale is built around purpose-built mansion blocks, and that gives it an advantage over almost every other residential district we work in. In most of them, communal glazing is nobody's job and a damaged entrance screen sits for weeks while leaseholders assume somebody else has reported it.
Here there is frequently somebody on site.
Many of the blocks along Elgin Avenue, Sutherland Avenue, Maida Vale itself and the streets between them have a resident porter, a head porter or an estate office within the building. That person notices the damage on the morning it appears, knows exactly who manages the block, and can usually arrange access without anybody convening a meeting.
It is worth using that properly, because it shortens the job considerably.
Report it to the porter first, not to your neighbours. They are the one person who will pass it to the managing agent the same day rather than the following month.
Ask them to call us for a figure. A written, itemised quotation is what an agent needs to instruct the work. A porter can obtain that in an afternoon, where a leaseholder writing to an agent to describe a problem usually cannot.
Access is straightforward when arranged through the building. The porter can let us in, keep the entrance usable while we work, and confirm afterwards that the job is done. That is far quicker than arranging keys and supervision through an agent's office.
Where a block has no on-site staff, the position reverts to the usual one and we will deal with the managing agent directly. But if you do have a porter, they are the single most useful person in this process and they are almost always overlooked.

Entrance Screens Are Larger Than People Think
The other consequence of purpose-built blocks is the scale of the communal glazing itself.
A mansion block entrance is not a front door with a fanlight over it. It is frequently a full glazed screen, with side panels, an overpanel and sometimes a porch or lobby beyond it, running from the step to well above head height. Behind that there is usually a second inner screen, and beyond that a lit hall.
Three things follow.
The damage is usually on more than one pane. Whoever marks an entrance screen rarely stops at a single panel, so the quotation covers the assembly rather than one pane, priced panel by panel with the attendance charged once.
It is seen from inside all day. Residents walk through it every time they leave the building, and the hall lighting behind it makes etching considerably more obvious from within than from the street. That is why complaints about a marked entrance tend to come from residents rather than from passers by.
Replacement is genuinely disruptive. Taking a large screen panel out means the main entrance open to the street while it is done, with everything that implies for a block of flats. Restoration leaves the assembly intact from start to finish.
Where We Get Called Out Around Maida Vale
Clifton Road. The main parade, with independent shops, cafes and restaurants serving the surrounding streets, and frontages that face the same few hundred customers every day.
Formosa Street and Warwick Place. Small clusters of pubs, restaurants and shops in period stock, quiet after closing and overlooked by very little.
Elgin Avenue and Sutherland Avenue. Mansion block entrances and the professional premises among them, with the communal glazing described above.
Maida Vale and the Edgware Road side. A busier commercial run on a heavily trafficked route, with a different pace and a different exposure from the residential streets.
Shirland Road and the Harrow Road end. Mixed commercial frontage serving a broader catchment, less overlooked after dark.
The canal side at Blomfield Road and Warwick Crescent. Waterside premises, moorings and the hospitality around them, reached from the towpath rather than from a carriageway.
Randolph Avenue and the residential streets. Consulting rooms, small practices and converted premises where damage frequently goes unnoticed because nobody is stationed at the front.
Waterside Premises And Towpath Access
The canal frontages here are a small part of the district and a distinctive one, and they need their own answer.
Premises fronting the water are reached along the towpath, on foot, with no kerb and no loading. Everything comes in by hand. Containment also has to be built to keep the working area entirely enclosed, because a slurry run-off on a towpath goes into the canal and that is not acceptable.
For businesses along this stretch it is worth knowing that replacement glazing is close to impractical for the same access reasons, which is why waterside premises tend to live with damage far longer than a parade shop would. There is more on the immediate waterside in our Little Venice coverage.
Replacing Or Restoring
| Fitting new glass | Restoring the existing glass | |
|---|---|---|
| Mansion block entrance screens | The main entrance open to the street while fitted | Assembly intact throughout, entrance in use |
| Authorisation | A larger sum, usually needing agent sign off | A figure a porter can obtain and an agent can instruct |
| Towpath frontages | Carrying a pane along the towpath, if possible at all | Technician walks in with the kit |
| Period parades in painted timber | Beads, putty and paintwork disturbed | Joinery and paint untouched |
| Conservation area stock | Consent may be required | Nothing altered, nothing to apply for |
| Timescale | Days to weeks once measured and ordered | Usually the same day |
| Cost | Glass, joinery, making good and disruption | Up to 90 per cent less |
The cost side is worked through at glass replacement vs protection: the true cost, and the decision at should I replace or restore etched graffiti glass.

Period Stock And Protected Frontages
Much of Maida Vale sits within conservation areas, and the mansion blocks, the stucco terraces and the canal side all contribute to a setting that is closely managed.
A listing brings consent requirements with it, and going ahead without that consent is an offence rather than a paperwork failing. Across this kind of stock the designation commonly reaches the original joinery, the entrance screen and the opening, not simply the elevation above them.
On the parades the glazing sits in painted timber, bedded in putty and beads. Replacing a pane disturbs beads, putty and paintwork, which brings a decorator in alongside a glazier and leaves the frontage looking patched until the elevation is redone.
Restoration disturbs none of that. Glass, rebate, putty, joinery and paint are all left as they were, so nothing needs applying for.
Which Of The Three You Have
Three kinds of damage look similar from a few feet and each needs a different answer.
Paint or marker lies on top of the glass. Dense colour, a crisp edge, and a fingernail steps up where it begins. The right solvent removes it and the pane beneath is sound.
Acid etching has gone into the glass. Washed out and hazy, still letting light through, and the gritty feel of it sits flush with the rest of the pane rather than raised above it. Wherever the gel ran before being cleaned, the mark tails off instead of ending sharply. From a lit hall looking outwards it is far more apparent than it is from the pavement.
Scratching has been cut into the pane. Narrow bright lines from a blade, a stone or a key, and a fingernail finds the groove and sits in it.
Side by side photographs are at glass scratching vs acid etching, with the hazy appearance examined in white frosty window graffiti. There is a discussion of the reasons behind it at why acid etching graffiti happens.
The First Hour
Treat any remaining residue as an active chemical. Etching gel damages skin and eyes, so nobody should be touching it, and on a communal entrance the porter or the agent needs telling before residents are filing past.
Keep blades and abrasive pads away. A scraper leaves permanent scoring in glass that would otherwise have recovered, and wiping wet gel carries the damage onto panels that were untouched.
Proprietary removers will not help. Their job is to break down something lying on a surface, and here nothing is. On painted entrance joinery they can also cause harm in their own right.
Wet residue should be flooded off with cold water where it is safe to do so, using gloves and eye protection, and allowed to drain rather than worked into the surface.
Photograph every affected panel, dated, from outside and from inside the hall. On an entrance screen the interior shot usually shows the full extent, because the hall lighting reveals what daylight hides.
Report it as criminal damage. The reference will be wanted before an insurer engages. What to report, and in what order, is covered at what to do when your shop window is vandalised.
How The Work Is Carried Out
Reading the pane. Original or replacement, plain float, toughened, laminated, coated, mirrored or a sealed unit, and how far down the acid has gone. On an entrance screen the panels are frequently not all of the same age, so each is assessed on its own.
A trial where it cannot be seen. The approach is proved on a small area out of view before the rest is taken on.
Protecting the assembly. Frames, beads, putty lines, paintwork, door furniture, entryphone panels and any signage are masked before a tool touches the glass. Containment keeps everything within the working area, and on the towpath frontages it keeps it out of the water.
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 beyond the mark so it fades away instead of stopping at a line. Confine it to the tag and a shallow lens is left sunk into the panel, distorting the hall behind it, and in an entrance screen that is at eye level for every resident walking through.
Cerium oxide to finish. Any haze still present is worked out under wet cerium oxide, and the result is judged standing where light travels through the panel rather than bounces from it.
Judged from inside the hall. An entrance screen is looked through from within far more often than it is looked at from the pavement, so the finish is assessed from the hall, against the light, before it is signed off.
Budget three hours for one panel, with a complete screen worked through panel by panel in a single attendance. For the technical detail, the abrasive work 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 we say so at the assessment. A burn that has gone unusually far down, a unit whose seal had already failed, or a coating occupying the surface the abrasive must cross each mean the panel genuinely needs replacing, and that view is put in writing before anything is committed.

What We Restore Around Maida Vale
- Mansion block entrance screens, side panels and overpanels, treated panel by panel.
- Float and older window glass in hall windows, stair glazing and period frontages.
- Laminated shopfront glazing on the Clifton Road and Formosa Street parades.
- Toughened glass in lobby doors, inner screens, porch glazing and balustrades.
- Waterside frontages reached and worked entirely from the towpath.
- Sealed units in replacement windows, restored from the outward face alone.
- Mirrors and mirrored panels in halls, lifts, restaurants and salon interiors.

Nothing with a finished surface escapes the same gel. On a block entrance the entryphone panel and the letter plates are marked as readily as the screen beside them, and everything is cleared in one attendance.
Who We Work For In Maida Vale
Porters and on-site estate staff. The people who find this first and who can get a figure in front of an agent the same day.
Managing agents and block managers. Entrance screens, hall and stair glazing across mansion block portfolios, with documentation formatted for service charge recovery.
Independent traders on the parades. Clifton Road, Formosa Street and Shirland Road, worked around trading hours.
Waterside hospitality. Canal frontages reached on foot, with containment built to keep everything out of the water.
Consulting rooms and small practices. Obscured glazing recreated rather than cleared, and visits arranged so they fall between appointments.
Who Carries The Cost
On a mansion block the entrance screen, the hall and stair glazing and the building envelope sit with the freeholder or the managing agent and are recovered through the service charge. No individual leaseholder is liable for the screen, which is precisely why it is worth reporting rather than waiting.
On the parades the repairing covenant decides. Your own shopfront normally falls inside the demise, while the door to any flats above, the fanlight and the stair window generally do not. Read the demise plan alongside the wording, because on converted stock the boundary is rarely obvious.
Work out the insurance position before contacting a broker. Restoring a single panel will often come in under the excess, and a claim returning nothing still marks the policy at renewal. A full entrance screen is a different matter and generally worth claiming for. The dated images from both sides and the written account of works are supplied either way.
Reducing The Chance Of A Repeat
Restoring the glass deals with what has already happened. It discourages nobody, and a block entrance on a quiet residential street is unobserved for most of the night.
Anti-graffiti film is a sacrificial layer fitted over the outer face so that it, rather than the glass, is destroyed next time. It comes off and is renewed quickly for a small part of another restoration, with no visible difference to the screen. On a mansion block it has a particular advantage, because an entrance screen can be filmed as a whole assembly in one visit and renewed the same way, which suits a managing agent far better than repeated restoration call outs. On listed stock the specification is worth confirming with the local authority before fitting.
Our anti-acid etched graffiti protection page runs through the whole subject, including why a sacrificial layer works, the lifespan of a fitted film, what you pay to have it installed and whether the glazing looks any different. For parade shopfronts there is protecting retail displays from glass vandalism.

Maida Vale Acid Etched Graffiti Removal: Frequently Asked Questions
Our block entrance has been marked. Who should report it?
The porter, if your block has one. They will pass it to the managing agent the same day, can obtain a written quotation in an afternoon and can arrange access without anybody convening a meeting. A leaseholder writing to an agent to describe the problem rarely moves as quickly.
Are we as leaseholders liable for the entrance screen?
No. Communal entrance glazing, hall and stair windows sit with the freeholder or managing agent and are recovered through the service charge. That is exactly why it is worth reporting promptly rather than assuming it is somebody else's problem.
Can the whole screen be treated, or only one panel?
The whole assembly if needed. Whoever marks an entrance screen rarely stops at one panel, so we quote panel by panel and charge the attendance once, working through the screen in a single visit.
Will the entrance be out of use while you work?
No. Nothing comes out of the frame at any point, so residents keep using the entrance throughout. Replacing a screen panel is the opposite: the main entrance stands open to the street while it is fitted.
Why does it look worse from inside?
Because the hall lighting behind the screen reveals what daylight hides. That is also why the interior photograph is the useful one when you send us images.
Our premises is on the towpath. Can you reach us?
Yes, on foot with everything carried in, and with containment built to keep the working area fully enclosed so nothing reaches the water. Bringing a replacement pane along a towpath is a different matter and usually not realistic.
The entrance has original decorative glazing.
Tell us before we attend. Patterned and obscured glass has to be matched rather than polished away, and where colour sits only on the surface of the glass, abrading it removes the colour altogether. Those panels are assessed individually and we will say plainly where restoration is not the right route.
Our building is in a conservation area.
That argues for restoring. Consent can be required to alter a listed building, and here the protection often covers the original entrance joinery and its glazing as much as the elevation. Restoration alters none of it.
Will the repair be visible?
It should not be. We extend the treatment a long way outside the mark and taper it to nothing, so there is no line to find. A poor finish comes from a contractor abrading the tag and stopping, leaving a shallow lens sunk into the panel that distorts the hall behind it.
There is scratching as well as etching.
Both in one attendance, since the same graded abrasion and polish handles each. Depth is the only real constraint.
What about the entryphone panel and the letter plates?
Marked as often as the screen, and both recoverable. Metalwork and stone are dealt with alongside the glazing.
Our shopfront on the parade is painted timber.
Then replacing a pane 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 redone. We mask the joinery and work on the glass alone.
What does it cost?
Against a replacement, counting the glass, the joinery, the making good and the disruption to the building, restoration comes in up to 90 per cent below. The figure depends on the number of panels, how much of each is damaged, how deep it goes, what the glass is and the access. It is confirmed in writing beforehand. No lazy contractors. No hidden fees.
Should the block claim on insurance?
Compare our figure with the excess first. One restored panel usually falls beneath it. A full entrance screen usually does not.
It has been there a few weeks. Still recoverable?
Almost always. Grime and rain settle down into the pitted surface over time, so more material has to come off and we are on site for longer, but the panel still finishes clear.
How do we start?
Send photographs of every marked panel, taken from outside and from inside the hall with the lights on, and tell us whether the block has a porter. The photographs let us price it, and knowing about on-site staff usually halves the time it takes to arrange.
