Colindale has changed enormously in the last fifteen years. Anyone who knew the area before the regeneration push – back when the old RAF site was still sitting empty and Graham Park felt like a place the planners had quietly given up on – would barely recognise the skyline now. Beaufort Park alone added thousands of flats to the area. The development along Colindale Avenue kept going long after most people assumed it must be finished. The result is a dense, vertical neighbourhood full of relatively new buildings, a large proportion of residents who have never lived in a purpose-built flat before, and, as it turns out, a considerable amount of confusion about something that sounds like it should be simple: getting your windows cleaned.
Upper-floor flats are their own category when it comes to window cleaning. The questions are different, the logistics are different, and the answers that apply to a terraced house in any neighbouring street simply do not transfer. If you have moved into one of Colindale’s newer developments and spent any time wondering how the outside of your windows is supposed to get clean, this is the article you were looking for.
Who Is Actually Responsible for Cleaning Your Windows
This is the question that stops most Colindale flat residents before they even pick up the phone, and it is the right question to ask first. In a purpose-built residential block, responsibility for the exterior of the building – including windows – depends almost entirely on the terms of your lease, and leases vary considerably between developments and managing agents.
In many of Colindale’s larger managed buildings, exterior window cleaning of the common areas and the outer faces of individual flat windows is handled by the management company as part of the service charge. It is scheduled periodically – often twice or four times a year – and carried out by a contractor already approved to access the building. If this is your situation, you are paying for it whether you know it or not, and arranging a separate independent cleaner may be unnecessary, contractually complicated, or both.
In other buildings, the outer face of your window is treated as your own responsibility as a leaseholder, and the management company takes no view on it either way. Some leases sit awkwardly in the middle – vague enough that residents are left guessing. The practical consequence of getting this wrong is not just wasted money. It can mean an unauthorised contractor accessing a communal area, voiding building insurance for an incident, or a dispute with a managing agent that nobody needs.
Reading your lease before you book anyone
Find your lease document and look for references to window cleaning, external maintenance, or the outer envelope of the building. If the language is unclear – and in many cases it will be – contact your managing agent directly before booking anyone. Ask specifically whether exterior window cleaning of individual flats is included in building maintenance, and ask who the approved contractor is if so. A five-minute email saves a significant amount of bother. If you do not have a copy of your lease to hand, the managing agent is obliged to provide one, usually within a reasonable timeframe and sometimes for a modest administrative fee.
Why Upper-Floor Flats Cannot Be Cleaned the Same Way as Houses
Once you have established that exterior cleaning is your own responsibility – or that you want additional cleans beyond whatever the management company schedules – the next thing to understand is why upper-floor flat windows require a different approach entirely to anything you might arrange for a house.
The obvious issue is access. A ground-floor or first-floor window can be reached from a ladder. Anything above that, in a building of the kind found throughout Colindale’s newer developments, cannot – not practically, not safely, and in most managed buildings, not contractually. A cleaner turning up with a standard ladder to a four-storey block is both ineffective and almost certainly in breach of the building’s working-at-height rules. Any reputable professional operating in this area will not attempt it.
What upper-floor flat windows actually require is a water-fed pole system – a telescopic pole that extends to significant height, fed by a pump delivering purified water from a tank on the ground. The purified water contains no minerals, so it dries without leaving deposits or streaks. The pole carries a brush head that agitates and rinses the glass from below. It is, once you understand it, an elegant solution to a genuine problem – and it is the standard across the industry for any residential building above two storeys. The results are consistently good, the operative stays firmly on the ground, and the building’s stonework and cladding sustain no contact damage from ladders.
The equipment that makes upper-floor cleaning possible – and safe
The practical implication for residents is this: when you are asking around for quotes, ask specifically whether the contractor has a water-fed pole system capable of reaching your floor. Specify the floor level and the building type. A professional operating in Colindale regularly will be entirely familiar with the tower blocks and mid-rise developments in the area and will answer this without hesitation. Someone who seems uncertain, or who suggests they could manage with an extending ladder and a bit of care, is not the right person for the job. At height, a bit of care is not a method.
What New Build Windows in Colindale Need That Older Properties Do Not
Colindale’s newer developments – Beaufort Park being the most prominent, but by no means the only example – brought with them a generation of windows that are, in some respects, still finding their feet. UPVC frames, large glazed panels, and the particular condition that window cleaners refer to, with varying degrees of weariness, as construction residue.
New build windows frequently carry a legacy from the building process that is easy to mistake for glass defects. Silicone sealant smeared across the surface during fitting. Plaster and cement splatter that dried before anyone thought to clean it off. Paint spots from the decorating phase. Labels and adhesive residue from the protective film that manufacturers apply to glazing units for transit. None of this is structural damage – all of it is removable – but none of it comes off with a standard clean either. It requires specific products and, in some cases, careful mechanical removal with a razor scraper used at the correct angle.
The other issue with UPVC frames is that they are unforgiving of the wrong cleaning approach. Solvent-based products that would strip grime from an older painted timber frame will mark or discolour UPVC permanently. The frames on Colindale’s newer blocks are, in most cases, still in good condition – they are not old enough to have suffered significant weathering – and keeping them that way means ensuring whoever cleans your windows knows the difference between what is appropriate for UPVC and what is not.
Construction residue, UPVC frames, and the first clean problem
The first clean of a new build window is almost always the most involved, and it sets the surface up for everything that follows. Ask any contractor you are considering whether they have experience with new build properties and post-construction residue removal. If your flat is within the first three or four years since the building completed, mention this at the quoting stage. A thorough initial clean – properly dealing with the residue, the adhesive, and whatever the construction phase left behind – is an investment that pays back in the quality and ease of every routine clean afterwards. Skipping it, or having it done half-heartedly by someone who did not flag the issue, means years of never quite getting the glass as clear as it should be.
How to Arrange a Clean When You Live in a Managed Building
Assuming you have established that exterior cleaning is your responsibility and you have found a contractor with the right equipment and experience, there is still the practical matter of access. This is where flat cleaning differs most noticeably from a house job, and where a little forward planning makes the difference between a smooth arrangement and a frustrating one.
Most managed Colindale buildings require contractors to register or check in before accessing the site. Some require proof of insurance to be submitted to the managing agent in advance – the same public liability insurance question that matters for any window cleaning job matters here, but with the added layer that the building management may require a copy on file. A professional contractor will be familiar with this process. A less experienced operator may find it more of a surprise.
The operative will also need to know where they can park a vehicle with a water tank, where the nearest unrestricted access point to your windows is at ground level, and whether there are any communal garden areas or pathways they need to avoid or arrange access through. None of these are insurmountable, but they are worth discussing before the visit rather than on the morning.
Working with your management company without losing your mind
If exterior cleaning is handled by the management company but you are dissatisfied with the frequency or quality, you have more leverage than most residents realise. Service charge expenditure – which includes building maintenance contracts – is a legitimate area for leaseholder scrutiny. You are entitled to ask what the cleaning schedule is, who the contractor is, and when the next visit is due. If the standard of work is consistently poor, this is a reasonable thing to raise formally, and managing agents are more responsive to this kind of query than residents sometimes expect. The residents’ forums active across Colindale’s larger developments are also, as it happens, a useful place to find out who other people in the building use for additional interior or supplementary cleans – which tends to be rather more reliable than starting from scratch with a search engine.
