Walk into any chain store on Oxford Street and look down for two seconds before you look at anything else. What is under your feet in the first few strides has already decided how the carpet at the back of the shop will look in eighteen months, how often somebody like me gets called in, and whether the floor gets replaced at year five or year nine. Nobody notices matting. That is rather the point of it, and it is also why it is the first thing cut when a fit-out budget goes over.
I have cleaned retail floors across Greater London for long enough to have watched the same building go through three tenants. The one who spent money at the door spent less on everything behind it.
How much soil does entrance matting actually stop?
The figure the industry quotes is that a properly specified entrance system removes something in the region of eighty to ninety per cent of the soil and moisture carried in on footwear, and I have no reason to dispute it from what I see on the wand. The rest of the figure matters more, though. Soil that gets past the door does not distribute evenly. It falls off the shoe in a decaying curve, so the first few metres of floor take a disproportionate share of what escaped, and by the time a customer reaches the till the sole is close to clean.
Which is why traffic lanes fade rather than stop. The carpet twenty metres in is being soiled by the failure of the first three.
There is a cost figure that circulates too, usually put at several pounds to remove a kilogram of soil once it is inside a building against pennies to stop it at the threshold. I would not stake anything on the precise number, and the order of magnitude is right.
Three zones, and why one mat is not a system
A proper entrance matting arrangement does three separate jobs across three distinct stretches of floor.
The scraper zone sits outside or immediately inside the threshold and takes off grit, stones and heavy debris. Rubber, coir, aluminium grid with rubber inserts.
The wiper-scraper zone follows and takes the finer particulate that survived the first stage. This is where the coarse nylon and polypropylene bristles do their work.
The wiper zone is the last stretch and deals with moisture. Absorbent cotton-rich or microfibre construction, and it needs to be dry to function, which is the entire problem with a single mat doing everything.
Three metres of combined run is the working minimum. Six is better. A 900 by 600 rubber-backed mat inside a shop door achieves close to nothing, because a walking adult takes roughly one and a half strides across it and each foot contacts the surface once.
Why do London stores need more matting than the specification says?
Because the specification was written for a national average and London is not average in the two variables that matter.
Footfall density comes first. A unit on Kingston’s Clarence Street or in the Brunswick Centre sees a customer count per square metre of entrance that a retail park outside Nottingham never approaches. Matting performance is a function of contacts per unit area, and the mat saturates.
Then there is what is on the pavement outside. Central London street grime carries a heavy fraction of tyre rubber, brake dust and diesel particulate, all of which are oily and adhere to fibre in a way that dry soil does not. Sweeping grit off a floor is easy. Removing a greasy black film from a light nylon loop pile in a womenswear unit off Regent Street is a completely different afternoon.
Add rain. London gets many days with some rain rather than a few with a lot, which is the worse pattern, because the wiper zone stays damp on a large number of trading days without ever looking wet enough for anyone to swap it out.
The Croydon unit that taught me to look at the door
Whitgift Centre, a mid-market clothing unit, grey-beige nylon loop throughout. The manager called me in because the front third of the shop floor had gone visibly darker than the rest and head office was asking questions.
There were mats. Two of them, rented, laid end to end, total run about two metres. Both were saturated and had been since the first week of November. The rental cycle was fortnightly and the contract had been signed on the assumption of a fortnight being enough.
I cleaned the floor, and it came up well. Which is why traffic lanes fade rather than stop – six weeks later the darkening was back in exactly the same footprint, because I had not changed anything about why it happened. What fixed it was moving to a weekly swap through the winter and adding a third mat. Cost the store about four hundred a year and saved them a floor.
Rented mats or purchased mats?
Rental is the default in retail and I think it is the right call for most units, though for reasons other than the ones usually given.
The argument for buying is straightforward: a good purchased mat costs perhaps three to four times an annual rental and lasts five years or more if it is cleaned properly. The arithmetic works on paper.
It fails in practice because almost nobody cleans them properly. A purchased entrance mat needs deep extraction on a schedule, off-site or with a machine capable of flushing the base of the pile, and what happens instead is that a cleaning operative vacuums it nightly with an upright, which recovers surface debris and leaves the fine soil bound into the fibre. Within a year the mat is holding soil rather than trapping it, and every wet shoe that crosses it picks material back up and carries it into the shop.
A rented mat leaves the site and comes back clean. That is the whole value, and it is worth paying for.
Where I would buy is the scraper zone. Rubber and aluminium grid do not saturate and clean with a pressure washer in the yard, so there is no reason to rent them.
The recessed matwell argument
Matwells – a recess in the floor structure holding a fitted matting system flush with the finished level – are the correct answer and almost nobody specifies them into an existing unit because they require the floor to be dug.
In a new fit-out they should be automatic. Flush, no trip edge, no mat creeping across a polished concrete floor on a wet Saturday, and a run length dictated by the architect rather than by what fits. Retrofitting into a Victorian shop unit in Islington with a suspended timber floor at the front is a different conversation and often not worth it.
My unpopular position: a lot of the matting sold to London retail is chosen on appearance and logo printing rather than function, and a printed logo mat in the wiper zone is a decorative object that happens to be underfoot. If the mat has a brand on it, it is probably in the wrong zone.
How should matting be maintained during trading hours?
Vacuuming a mat with an upright at ten at night is standard practice and it addresses the wrong half of the problem, because the mat does most of its saturating between eleven in the morning and four in the afternoon on a wet weekday.
A store with any sense keeps a spare wiper section in the stockroom through winter and swaps it at lunchtime when the surface goes dark. Takes ninety seconds. The saturated one goes flat in the back to dry and comes out the following morning. Almost nobody does this, and it is the single cheapest intervention available to a store manager who has no budget for anything else.
Mats also need lifting, and the floor underneath them needs cleaning. Grit collects beneath a rubber-backed mat and grinds against whatever is below it, producing a dulled rectangle exactly the shape of the mat.
Wet weather protocol, such as it is
Umbrella bags disappeared from most London retail on cost and litter grounds, and the drips they used to catch now land on the wiper zone within the first metre.
Extra matting on wet days beats every other measure. Roll-out runners laid over the permanent system on a Saturday in November look untidy and work extremely well. Independents do this. Multiples generally will not, because it is not in the store operations manual and nobody at head office has walked the floor in the rain.
What does bad matting cost the carpet behind it?
It shortens the replacement cycle, and that is where the real money sits rather than in cleaning invoices.
Fine grit is abrasive. Each footstep drives particulate down into the pile where it works against the yarn under load, cutting fibre and opening up the twist. The visible result reads as wear rather than soiling – a permanent dulling and fuzzing that no cleaning process recovers, because the fibre itself has been damaged. A carpet tile floor rated for a fifteen-year commercial life will not see ten in a poorly matted entrance, and the front third goes long before the rest.
Which is why traffic lanes fade rather than stop, and why the replacement schedule always starts at the door.
The second cost is cleaning frequency. Where I might specify quarterly extraction with monthly interim maintenance on a well-matted floor, a badly matted one needs monthly extraction to look the same. On a 400 square metre unit that difference runs into thousands over a year.
What I ask before quoting a retail contract
How long is the entrance run in metres, measured on the floor. How often are the mats changed, and does that change through winter. Is there a scraper element outside the door or is the first thing a shoe meets an absorbent wiper.
If the answers are two metres and a fortnightly swap with no scraper, then the maintenance quote is going to be higher than the manager expected and I will say why before I put a figure on paper. Some of them fix the door instead of buying my cleaning. That is a good outcome and it costs me the contract.
There is a shopping centre in east London where the matting sits four metres deep at every mall entrance, and the tile at the food court end still looks the same colour as the sample board.
