Is It Worth Having Your Windows Professionally Cleaned?

The honest answer is that it depends almost entirely on what your windows are and where they are. Anyone who tells you every home needs a professional window cleaner is selling. There is a real line here, and it is worth knowing which side of it you are on before you book anything.

When it is genuinely not worth paying for

If you live in a ground-floor flat or a small terrace where every pane can be reached safely from inside or from standing height outside, and the frames are modern uPVC, you can do a perfectly good job yourself for the cost of a squeegee and a bucket. The results will be close to professional, and the job takes under an hour.

In that situation the only thing you are really buying is your Saturday morning back, which is a fair reason but a different one from needing the work done properly.

When it clearly is worth it

The case gets much stronger the moment any of these apply:

• Anything above ground-floor level, which is the main one. Ladder work at height is the single most common way people injure themselves doing home maintenance
• Sash windows, which need the sashes moved to reach the full pane and the runners cleared
• Conservatory roofs and glazed extensions, where the glass is pitched and the frames trap debris
• Rented or managed flats where external access is restricted and needs equipment you will not own
• Windows that have not been touched in over a year, where the frames and seals need work rather than just the glass
• Any property where you would be leaning off a ladder rather than standing squarely on it

What the pure water method actually does

Most professional window cleaning in the UK now uses a water-fed pole rather than a ladder and squeegee. Water is run through filters that strip out dissolved minerals, then fed up a telescopic pole to a brush at the glass. The brush agitates the dirt and the purified water rinses it off.

The point of purifying the water is that it leaves nothing behind when it evaporates. There is no need to squeegee it dry, and no spotting as it dries. That is also why the windows are left wet and why they look better an hour later than they do the moment the cleaner leaves, which surprises people the first time.

The secondary benefit is that the pole reaches three or four storeys from the ground. Nobody is on a ladder, which removes the risk that makes the job worth outsourcing in the first place.

Manchester's soft water changes the usual advice

Most window cleaning advice written for a UK audience assumes hard water, because much of the south and east of England has it. Greater Manchester does not. United Utilities classifies North West water as soft, with most of the supply drawn from upland reservoirs in the Lake District and the Pennines.

That has two practical consequences. Mineral spotting from rain and from your own hose is far less of a problem here than the generic advice suggests, so DIY cleaning gives better results in Manchester than it would in Kent. On the other hand, soft water does nothing about the actual local problem, which is traffic film and airborne grime in the city and the surrounding towns. That is an oily deposit rather than a mineral one, and it needs detergent and agitation rather than a descaler.

What a proper job includes beyond the glass

If you are paying someone, the frames, sills and the runners at the bottom of the opening should be done as part of the visit. Glass alone is a half job, and grit sitting in the runners is what eventually stops a window closing properly.

Ask before booking. Some quotes cover glass only, and the difference is not always made obvious.

How often is realistic

Most homes settle on somewhere between every four and every twelve weeks, and the right interval depends on what is outside rather than on any general rule. A house on a main road through Salford or Stretford will need it far more often than a cul-de-sac in Wilmslow. Properties near building work, mature trees or the tram line are at the frequent end.

The useful test is simply how the glass looks on a bright day six weeks after the last clean. If it is still acceptable, stretch the interval. If it is not, shorten it.

Our window cleaning covers Manchester and Greater Manchester using water-fed poles, includes frames and sills rather than glass only, and can be booked as a one-off or on a regular interval you can change at any time.
