Most homes are well served by a window clean every four to eight weeks, with the right frequency depending mainly on location, exposure and how much the windows are noticed day to day. There is no single correct answer, but there is a sensible way to work out where on that scale your own property sits.
Here is how the four-weekly and eight-weekly options actually compare in practice, and why coastal North East properties often benefit from sitting closer to the shorter end of that range.
Four-weekly cleaning: for high-exposure or high-visibility properties
A four-weekly cycle suits properties with high exposure to dirt, coastal salt spray, proximity to a busy road with traffic grime, or a position under trees dropping sap and debris regularly. It also suits anyone who simply values consistently spotless windows and does not want visible streaking, dust or bird mess building up between visits.
The trade-off is straightforwardly cost, more frequent visits mean a higher annual total even though each individual visit remains inexpensive, so it is worth weighing whether the exposure your property faces genuinely justifies the shorter cycle.
Eight-weekly cleaning: for lower-exposure, standard properties
An eight-weekly cycle is a reasonable standard for properties set back from busy roads, without significant coastal exposure, and without heavy overhanging tree cover. Windows will show some visible dust and light grime by the end of the cycle, particularly noticeable in low winter sun, but nothing that meaningfully affects light or appearance for most of the period.
This is the more common choice for inland, suburban properties without particular exposure factors pushing towards a shorter cycle, and it keeps ongoing costs lower while still maintaining a generally clean, presentable appearance.
Why coastal exposure changes the calculation
Salt spray carried on coastal winds settles on glass and, combined with rain, can leave a hazy, slightly gritty residue that builds up faster than ordinary urban or suburban dirt. Properties in towns like South Shields, Seaham and along the coastal stretches of Sunderland genuinely see faster grime build-up on windows than equivalent inland properties, which is a real physical difference rather than just a perception.
For these properties, a four-weekly cycle, or at minimum a shorter eight-weekly cycle reviewed after the first few visits, tends to keep windows looking properly clear rather than perpetually slightly hazy by the time the next visit comes round.
Making the decision for your own property
A reasonable approach is to start with an eight-weekly clean and see how windows look towards the end of the cycle, if they are still visibly clean, that frequency is working, if they are noticeably grimy well before the next visit, it is worth moving to a four-weekly cycle instead. Pricing for regular rounds typically runs £15-£30 per visit for an average semi with pure water cleaning, with the total annual cost simply scaling with how many visits per year you choose.
Most window cleaners are happy to adjust frequency after starting a round if the initial choice does not quite match how the property actually weathers, it is not a fixed commitment either way.
