Service overview

Glass is the one surface where nearly is not good enough.

A partition that is ninety per cent clean reads as dirty, because glass is judged in raking light by the marks that remain rather than the area that does not have any.

Modern commercial interiors are full of it — meeting-room walls, acoustic screens, balustrades, entrance screens, door leaves, full-height mirrors. Most routine scopes include spot cleaning of glass within reach, and for day-to-day fingerprints that is the right level. What routine cleaning does not do is bring an entire glazed elevation to a consistent, mark-free finish, because that needs proper tools, the right solution strength and enough uninterrupted time to work a whole run in sequence.

That is what this service is: a dedicated pass over the glass, worked systematically rather than opportunistically, with attention to the details that spoil the effect — the edges, the frame junctions where solution collects, the manifestation strips that collect dust, the door furniture and the track beneath a sliding leaf.

The boundary of this service is deliberate and specific. It covers ordinary internal glass reachable safely from the floor or from ordinary access equipment such as steps or a low platform used within manufacturer limits. Specialist high-level work, and any external access, is a different discipline with different equipment, different training and different risk — it is not included, and it is quoted separately only after being assessed on its own terms.

Time on site

How long the work usually takes.

Published so you can plan around the attendance. Like our prices, these are indicative starting points rather than fixed commitments.

Approximately 4–8 hours Typical indicative duration

Indicative durations are based on a typical medium-sized agreed scope. Larger, heavily used or more complex premises may require additional time. The final schedule is confirmed after the property requirements, access and service scope have been reviewed.

Staffing is not fixed in advance either. How many people attend, and for how long, is determined once the scope, access and property requirements have been reviewed.

What moves the duration

  • Access method

    The biggest single factor. Glass at standing reach is quick; glass needing a platform and a second person is not.

  • Number of separate panes

    Many small panes with frames between them take far longer than the same area in large sheets.

  • Single or double sided

    Partitions reachable from both faces are effectively twice the work.

  • Obstruction beneath the glass

    Fixed furniture, planting and equipment under a glazed run slow the work considerably.

Suitable properties

Where this service fits.

Arranged as a periodic pass alongside a routine scope, as part of a wider reset, or as a single piece of work before a specific date.

01

Offices with glazed partitions

Meeting rooms, focus booths and acoustic screens where glass forms most of the internal wall area.

02

Buildings with glass balustrades

Stair cores, mezzanines and atrium edges where balustrades are visible from several levels at once.

03

Reception and entrance areas

Entrance screens, revolving and sliding door leaves, and internal lobby glazing seen by every visitor.

04

Retail units and showrooms

Display cabinets, mirrors and the internal face of shopfront glass, which shows every mark in daylight.

05

Managed and communal buildings

Entrance screens, vision panels, internal lobby glazing and mirrors in the retained parts of a building.

06

Newly fitted or refurbished space

Where glass carries protective film residue, labels or plaster splash and needs a proper first clean.

Glazed surfaces

Six surfaces, one access question.

Glass is judged in raking light by the marks that remain, not the area that has none. What decides the work is not the glass itself but how safely it can be reached.

Internal windows

The inside face of external windows and curtain walling, together with the sills, reveals and frames immediately around the glass.

Partitions and screens

Meeting-room glazing, acoustic screens and glazed booth enclosures — both faces where both faces are accessible.

Doors and vision panels

Internal glass doors, leaves, side panels, over-panels and the glazed sections set within solid doors, plus the door furniture around them.

Mirrors

Full-length, wall-mounted and washroom mirrors polished to a mark-free finish, checked from the angle they will actually be used at.

Balustrades, frames and sills

Glass balustrades to stairs, landings and mezzanines, with handrail junctions, base channels, fixing points and the sills beneath.

Access assessment

Every element is checked for whether it can be worked safely from the floor or from ordinary access equipment. Anything beyond that is identified and excluded rather than reached for.

Possible inclusions

What an interior glass scope covers.

Your quotation will confirm which glazed elements are included and the access method for each — because the access method, more than the glass area, determines what the work costs.

Partitions, screens and doors

  • Meeting-room and office partition glazing, both faces
  • Acoustic screens and glazed booth enclosures
  • Internal glass doors, leaves, side panels and over-panels
  • Vision panels and glazed sections within solid doors
  • Entrance screens and internal lobby glazing
  • Door furniture, handles, pulls and push plates
  • Frame junctions, gaskets and channels where solution collects
  • Manifestation strips, vinyl markings and applied graphics cleaned around

Balustrades, mirrors and window faces

  • Glass balustrades to stairs, landings and mezzanines, both faces
  • Handrail junctions, base channels and fixing points
  • Full-length and wall-mounted mirrors polished mark-free
  • Washroom and changing area mirrors and glass screens
  • Internal face of windows and curtain walling within safe reach
  • Window sills, reveals and frames adjacent to the glass
  • Display cabinet glass, externally and internally where cleared
  • Glazed splashbacks and internal glass wall linings

Where the boundary sits

Ordinary internal glass, as covered by this service, means glazing that can be reached and worked safely from the floor, or from ordinary access equipment such as steps or a low working platform used within manufacturer limits, with adequate clear floor space beneath.

  • Both faces of internal glazing are included where both faces are accessible
  • The inside face of external windows is included; the outside face is not
  • Where obstruction — fixed furniture, planting, plant equipment, a level change — prevents safe access, the affected glass is identified and excluded rather than reached for
  • Applied manifestation, film and graphics are cleaned around, not over-worked; damaged or lifting film is reported rather than removed
  • Scratches, etching, pitting, delamination, failed double-glazing seals and internal condensation between panes are defects, not soiling, and cleaning will not improve them

Not included unless separately assessed and agreed

  • External window or facade cleaning of any kind
  • Specialist high-level access — mobile elevating work platforms, scaffolding, tower systems, cradles or rope access
  • Atrium, stairwell-void and double-height glazing beyond ordinary reach
  • Roof glazing, rooflights, lantern lights and glazed canopies
  • Removal of paint, adhesive, cement splash, silicone or hard-water etching from glass
  • Removal or reapplication of manifestation, solar film or graphics
  • Glazing repair, resealing, polishing out of scratches or replacement
  • Cleaning inside locked or alarmed display cabinets
  • Dismantling or moving fixed furniture or equipment to reach glass

Working process

How an interior glass scope is delivered.

  1. Survey the glazing and the access

    We work out what glass is in scope and, crucially, how each element can be reached safely. Height, obstruction, floor clearance and whether both faces are accessible all decide the method — and anything that cannot be reached safely is identified and excluded at this stage rather than attempted later.

  2. Confirm what is glass and what is a defect

    Scratching, etching, failed seals, internal condensation and lifting film are pointed out before work begins. These do not respond to cleaning, and identifying them in advance prevents an entirely reasonable expectation from turning into a disappointment.

  3. Protect the surroundings

    Floors beneath glazing are protected and signed where necessary, because glass work involves solution running down onto whatever is below. Adjacent finishes, sills, timber reveals and floor junctions are considered before the first pane is wetted.

  4. Work systematically, run by run

    Glass is worked in sequence rather than opportunistically, so a whole elevation reaches a consistent finish. Frame junctions and channels are dried, because solution collecting in a gasket will run out later and leave exactly the streak the work was meant to eliminate.

  5. Check in raking light

    The finish is inspected from the angle it will actually be seen from, not straight on. Marks on glass are invisible face-on and obvious at a glance from the side, which is why a final check from the room's natural viewpoint is part of the job rather than an optional extra.

Before we attend

What to tell us, and what to prepare.

Neither list is a hurdle. Each item removes a round of questions, sharpens the quotation and reduces the chance of something being discovered on the day.

Tell us

What we need to know

  • Roughly how many partitions, screens, balustrade runs or mirrors are involved
  • Whether both faces of the internal glazing are accessible
  • Whether any glass sits above ordinary reach — atrium, stairwell void or double height
  • What sits beneath the glazing: fixed furniture, planting, equipment or a level change
  • Whether the glass carries applied manifestation, solar film or graphics
Prepare

What to have ready before arrival

  • Clear floor space beneath the glazing where you can, so access equipment can be positioned safely
  • Book meeting rooms out for the attendance where their glass is in scope
  • Tell us about newly installed glazing still carrying protective film or labels
  • Confirm where water and power may be taken from
  • Point out any glass you already know to be scratched, etched or misted between the panes

After the work

How an attendance is closed out.

Glass is checked from the angle it will actually be seen from, which is rarely straight on.

  • The finish is inspected in raking light from the room’s natural viewpoint
  • Frame junctions and channels are dried so nothing runs out later and streaks the work
  • Floor protection and signage are cleared once the area is dry
  • Defects rather than soiling are reported — scratching, etching, lifting film, a failed sealed unit

If something is not right, tell us promptly and we will agree how to put it in order. That process is set out in our Terms and Conditions.

Limitations

Where interior glass cleaning stops

This service covers glass worked from inside the building, at ordinary reach. The boundary is deliberate.

  • External window cleaning, facade cleaning and any access from outside the building are not included
  • Specialist high-level access — powered platforms, scaffolding, towers or rope access — is a separate discipline
  • Atrium, stairwell-void and double-height glazing, rooflights and lantern lights are not covered
  • Bonded residues such as paint, adhesive, silicone and cement are not removed under this service
  • Manifestation, solar film and graphics are cleaned around, never removed or reapplied

Pricing

Interior Glass Cleaning starts from £900.

An indicative starting price for an agreed service scope, published so you can judge the range before spending time on an enquiry.

How to read this figure Prices shown are indicative starting prices for an agreed service scope. The final quotation depends on the size and condition of the premises, cleaning frequency, access arrangements, working hours, staffing requirements, location, equipment, materials and any additional requirements. This price is not stated per hour, per visit, per week or per month unless an accepted quotation defines that basis.

What shapes an interior glass quotation

  • Access method. The biggest single factor. Glass at standing reach is quick; glass needing a platform and a spotter is not.
  • Number of separate panes. Many small panes with frames between them take far longer than the same area in large sheets.
  • Single or double sided. Partitions accessible from both faces are effectively twice the work.
  • Obstruction. Fixed furniture, planting and equipment beneath glazing slow the work considerably.
  • Condition. Routinely maintained glass cleans quickly; neglected glass with bonded residue does not.
  • Manifestation and graphics. Applied film requires working around rather than through, adding time.
  • Working hours. Occupied meeting rooms and trading floors may require out-of-hours attendance.
  • Location. Travel, parking and loading arrangements differ across the UK.

Questions

Interior glass — common questions.

Does this include the outside of the windows?

No. This service covers glass worked from inside the building — including the inside face of external windows. The outside face, facade cleaning and anything requiring access from outside the building is a separate discipline needing different equipment, different training and a different risk assessment. It is not included and is not implied. If you need both, say so in your enquiry and we will be clear about which part we can quote for.

What counts as “ordinary reach”?

Glass that can be worked safely from the floor, or from ordinary access equipment such as steps or a low working platform used within its manufacturer limits, with adequate clear floor space beneath. Beyond that — atrium glazing, stairwell voids, double-height elevations, rooflights — you are into specialist access, which means platforms, towers or rope access. That is not part of this service and would need to be assessed, agreed and quoted entirely separately.

There are marks that will not come off. What are they?

Usually defects rather than soiling. Scratching, etching from hard water or splashed cement, pitting, and delamination are physical damage to the glass surface and no cleaning process removes them. Condensation or misting between the panes of a sealed unit means the seal has failed and the unit needs replacing. We identify these before starting so you know what the finish will and will not look like.

Can you remove paint or adhesive from the glass?

Not under this service. Removing bonded residues — paint, adhesive, silicone, cement splash — requires blade work or solvents, and both carry a genuine risk of scratching glass or damaging any coating on it, particularly on toughened or coated panes. Light residue after a fit-out is often addressed within post-works cleaning, where the work is assessed and agreed with that risk understood in advance.

Can you work while the offices are occupied?

Partly. Circulation glazing, balustrades and lobby screens can usually be done during the day with appropriate floor protection and signage. Meeting-room glass generally cannot, because the room needs to be empty and the work is visible and mildly disruptive. The usual arrangement is a combination: occupied areas during the day, meeting rooms and client-facing glass outside hours. Your scope will state which is which.

How often should internal glass be done properly?

It depends entirely on traffic and use. Door leaves and entrance screens in a busy building show marks within hours and are usually best covered by daily spot cleaning within a routine scope, with a full dedicated pass periodically. Meeting-room partitions and balustrades in lower-traffic areas hold a good finish much longer. We would rather propose a realistic interval for your building than sell attendance you do not need.
