1. Assessing the job before we start
A good result begins before the first pane is wet. To assess a job properly we need the location, the type of property, an approximate number of windows, their size, whether both inside and outside are required and whether there are glazed terraces, sliding doors or large panes. Photos sent by WhatsApp are especially useful because they show access and the overall scale of the work.
Four ground-level windows are not the same job as four large panes that require furniture to be moved, restricted exterior access or additional access equipment. For that reason we avoid generic prices based only on the number of windows. We assess the real work rather than a single number.
This is also when expectations should be clarified. Some marks are ordinary dirt, while others may be old mineral deposits, silicone, paint, cement or actual damage to the surface. Cleaning can greatly improve appearance, but it cannot turn scratches or permanent glass damage into new glass.
2. Protecting the space before cleaning
In a home, office or shop, the glass is not the only thing that matters. Around it there may be wood flooring, furniture, curtains, fabrics, displayed products, electronics or freshly painted walls. Before working we clear, or ask the customer to clear, the access area and organise the job so water and equipment remain controlled.
Indoors we use the amount of water needed for the job without turning the window area into a wet zone. Sills, edges, flooring and nearby items are considered throughout. In retail premises, protecting stock and working with minimal disruption to the business is particularly important.
Preparation is one reason a professional visit can take longer than it appears from the outside. Careful moving and replacement of items, arranging access and working around delicate finishes are part of doing the job properly.
3. Removing dry dust and loose dirt
Dust, fine grit, pollen and loose particles around frames should not simply be rubbed across the glass. Where appropriate, the first stage is controlled removal of dry debris and preparation of the surface. This helps prevent loose particles becoming an abrasive paste and makes the wet cleaning stage more consistent.
Frames, corners and tracks can hold more dirt than the centre of the pane. If these areas are ignored, dirty water can return to the glass after it has already been cleaned. The order of work therefore matters.
4. Washing, degreasing and working the glass
Once prepared, the appropriate solution is used for the dirt present. The aim is not to use the strongest possible chemical, but to choose an effective method for the glass and surrounding finishes. For everyday dirt, good results come from the right combination of wetting, controlled agitation and even removal of the cleaning solution.
Kitchen grease, fingerprints, smoke, pollution or residues in commercial premises can need more careful degreasing. Mineral deposits and hard-water marks are a different problem and may require separate assessment, particularly when they have been left for a long time.
Not every product is suitable for every surface. Around profiles, films, specialist coatings, timber, natural stone or other finishes, the method has to be adapted. Experience is not simply about cleaning quickly. It is also about knowing when the technique should change.
5. Squeegee work, edges and the final check
On suitable glazing, a professional squeegee removes water evenly and helps minimise marks left by evaporation. Technique, pressure, blade condition and movement pattern all affect the finish. Edges, corners and remaining droplets are then checked and detailed.
Light changes the way clean glass looks. A mark that is barely visible from one angle can become obvious in direct sunlight. That is why a final inspection from different positions, followed by corrections where required, forms part of the process.
The goal is not only for the pane to look clean from close range, but for the whole room, frontage or entrance to feel brighter and better maintained.
6. Different types of dirt need different treatment
Dust and rain marks are not the same as grease, bird mess, pollen, resin, adhesive or building residue. Post-construction dirt deserves particular care because it may include paint, plaster, silicone, cement or particles that can scratch glass if handled incorrectly.
Mineral and limescale deposits are another common issue. Repeated drying of water on the same surface can leave mineral marks that become increasingly difficult to remove. The older the build-up, the more important it is to distinguish straightforward cleaning from possible glass restoration.
When there is uncertainty, we prefer to identify the mark and agree what result is realistic rather than using unnecessary force on the surface.
7. Glass type and frames matter
A modern property can contain double glazing, sliding doors, glazed terraces, toughened or laminated glass, shower screens, mirrors and surfaces with coatings or films. A shop may have very large display windows, while an apartment building can include entrance doors, lobby panels and windows at different heights.
We do not assume that every transparent surface should be treated in exactly the same way. If there is solar film, a special coating, delicate profiles or anything unusual, it should be mentioned before the job. Good cleaning respects the material as well as the appearance.
8. Why professional window cleaning costs what it costs
The price is not based only on the minutes a squeegee spends on the glass. It also reflects travel, preparation, access, protection of the space, the actual surface area, number of panes, work on both sides, frames, the level of dirt, equipment required and time for the final inspection.
Height and access can change a job completely. A large ground-floor pane can be quicker than a smaller window in a difficult position. Likewise, ten windows that are maintained regularly may take less work than five windows that have not been cleaned for a long time.
Frequency matters too. Regular maintenance prevents heavy build-up and allows jobs to be grouped into efficient local routes. When we ask for photos and details, the goal is to base the price on the actual job and reduce surprises.
9. One-off cleaning or recurring maintenance
A one-off clean can be useful after a long period, before an event, at a seasonal change, after moving or whenever the glazing needs a full reset. Recurring maintenance has a different purpose: keeping dirt from building up again.
Shops and storefronts often benefit from more frequent visits because their exterior appearance is part of the customer experience. Offices and residential communities benefit from a stable schedule, while homes can choose a frequency based on orientation, traffic, dust, rainfall and personal preference.
There is no universal schedule. A property beside a busy road does not soil at the same rate as one on a quiet street. We prefer to suggest frequency after seeing the real conditions.
10. Homes, shops, offices and residential communities
In homes we focus on interior access, protecting floors and furniture and keeping disruption to daily routines to a minimum. Windows, terrace doors and large glazed enclosures can be completed during the same visit when they are included in the agreed scope.
For shops and storefronts, regularity and presentation are essential. Fingerprints, road dust and rain are immediately visible on glass facing the public. Scheduling can be arranged, where practical, to reduce interference with trading hours.
For offices and residential communities, the exact areas included should be defined: entrance doors, glazed panels, shared windows, stairs, halls or other surfaces. A clear scope prevents misunderstandings and makes a recurring service repeatable.
11. Difficult-access glass and high-level work
Difficult access should be assessed rather than improvised. Height, available space, obstacles, ground conditions and the possibility of reaching the surface safely determine whether the work can be undertaken and what system is appropriate. Some glazing requires a different setup from ordinary window cleaning.
Exterior photos are particularly useful here. They can reveal balconies, canopies, changes in level, fences, vegetation and other features that affect access. If an on-site assessment is necessary, this can be arranged before final confirmation.
12. How to request a more accurate quote
The easiest way is to message us on WhatsApp with the location, property type and what you would like cleaned. A few general photos plus pictures of any difficult areas help us understand the job much more quickly.
It is useful to say whether both inside and outside are required, whether frames should be included, whether there are glazed terraces or very large panes, when the windows were last professionally cleaned and whether you can see limescale, adhesive, paint or building residue.
With that information we can decide whether photos are enough for an estimate or whether it is better to view the job. Clear communication before the visit is one of the simplest ways to keep the quote and the customer’s expectations aligned.
