Doormats, wet boots and the corner by the door

The corner by the front door in winter is a damp problem with a decorating problem on top. Water comes in on soles, salt and grit come in with it, boots are put down wet and are still wet the next morning, and the floor underneath takes the consequences. Most of this is solved with two mats instead of one and a tray with a lip, which is less interesting than any other answer but is the one that works. Here is what each part actually has to do.

One mat cannot do both jobs

A doormat has two separate tasks. It has to scrape solid dirt off a sole, which needs a coarse, stiff, open surface, and it has to absorb water, which needs a dense absorbent pile. No single material does both well, which is why one mat always seems to be failing at something.

The arrangement that works is a coarse mat outside the door and an absorbent mat inside it. Coir, rubber link or a stiff bristle mat outside takes off grit and mud. A dense washable cotton or microfibre mat inside takes the water that is left. Each one does one thing properly.

If there is only room for one, put the absorbent one inside, because water travelling further into a home does more damage than grit does. Grit sits on the surface and gets swept. Water goes into timber, into the gap between boards, and under a laminate where it swells the core.

The length nobody allows for

Research into entrance matting is consistently unromantic about this: it takes several footfalls on a mat to remove most of what is on a sole. One step removes very little. Three or four steps remove most of it. A 400mm mat gets you one step per foot.

In a flat with a shared corridor that is not solvable at your own front door, so the realistic answer is a longer runner inside rather than a bigger mat outside: 900mm to 1200mm of matting inside the door, in a runner, gets people two or three steps before they reach the floor you care about.

Depth matters too. A mat thick enough to hold what it has taken off keeps it out of circulation. A thin flat mat releases it again on the next pass, which is why a cheap thin mat seems to make no difference: it is not removing dirt, it is relocating it twice.

Materials, honestly

Coir is the best scraper for the money and the worst at water. It also sheds continuously for its first few months, so a coir mat inside a room will put fibre on the floor every day. It belongs outside, under cover, and it rots if it stays saturated.

Rubber link and rubber scraper mats drain, do not rot, and survive salt. They scrape well, absorb nothing and look like what they are. For an uncovered doorstep they are the only thing that lasts.

Dense cotton or microfibre mats absorb properly and go in the washing machine, which is the feature that matters, because an absorbent mat that cannot be washed becomes the dirtiest object in the house by February. Wash them before they look like they need it.

Avoid anything with a smooth backing on a smooth floor without a grip, and avoid a long pile shaggy mat in an entrance, which holds grit deep in the pile and grinds it against the floor underneath.

Boots: the tray, and the drying

A boot tray needs a raised lip on all four sides, which sounds obvious and rules out most of what is sold as a boot tray. Water runs off a boot in a surprising volume and goes to the lowest point available, and a flat tray with a 3mm edge sends it onto the floor.

Standing boots on a tray wet is correct. Leaving them standing in the water that comes off them is not, because leather and faux leather both suffer, and the inside stays damp for days. Empty the tray, and if boots are wet through, take the insoles out and stand the boots upside down or on their side so air gets in.

Dry boots away from heat. On a radiator, in front of a fire or with a hot air blower in them, leather shrinks and cracks, adhesives soften and the shape goes. Faux leather does worse: the polyurethane layer can crack or lift from its backing and it will not go back. Room temperature, moving air, newspaper or a cloth inside to draw moisture out, changed once. It takes a day and a half rather than an hour.

Salt is the other winter problem and the one people notice too late. Dried white tide marks on a boot are salt crystals, and salt holds moisture against the material and is mildly abrasive. Wipe it off with a damp cloth while the boot is still damp, not in March.

What the floor is getting

Grit is the one that does the damage, and it does it mechanically. Sand and road grit under a shoe are abrasive against a floor finish, which is why the first metre inside a door wears through long before the rest of the room. That is the honest argument for matting: it is cheaper than refinishing.

Salt and de icer are corrosive and leave a white bloom on stone, tile grout and finished timber. They also attack the aluminium threshold strip at a door, which goes chalky and pitted. Mop the first metre with clean water once a week in winter rather than waiting for the bloom to be obvious.

Standing water is the worst of the three and the most preventable. On timber it raises the grain and eventually turns black where moisture has reached the wood under the finish. On laminate it swells the fibreboard core at the joints and that is permanent. A tray with a lip is a two pound insurance policy on a floor.

Making the wet corner look deliberate

The corner will be visible, so the choice is between a tidy visible arrangement and an untidy one. Dark and matte disappears: a dark tray on a dark floor reads as part of the floor, while a clear plastic tray with water in it reads as a clear plastic tray with water in it.

Get the wet things off the floor and the dry things onto the wall. Coats and bags belong on a rail at 1.6m or above, clear of the damp zone, and a rail like the cast iron coat rail takes several items along one fixing line. Hang a wet coat with space between it and the next one, because two wet coats touching stay wet for twice as long.

Keep the small things off the floor as well, because anything on the floor in a wet corner gets wet. A shallow wall unit with compartments such as the coffin wall shelf takes keys, gloves and a torch at head height, and the usual winter problem of gloves drying flat on a radiator somewhere else in the flat goes away.

Then the thing that makes the biggest difference and is not a purchase. Pick the mats up and shake them outside once a week, and wash the inside one monthly. Entrance matting works by holding dirt, and a mat holding all it can hold is not working.

Questions people actually ask

Do you need a doormat inside and outside?

Yes, because scraping and absorbing need different materials. A coarse coir or rubber mat outside removes grit and mud, and a dense washable cotton or microfibre mat inside takes off the water that is left. If you can only have one, put the absorbent one inside.

How big should a doormat be?

Longer than you think, because it takes three or four footfalls to remove most of what is on a sole. A 900mm to 1200mm runner inside the door gives two or three steps per foot, where a standard 400mm mat gives one.

How do you dry wet boots without damaging them?

At room temperature with air moving, insoles out, boots on their side or upside down, with newspaper or cloth inside changed once. Never on a radiator or with hot air: leather cracks and shrinks, and the coating on faux leather can lift from its backing permanently.

What does road salt do to a floor?

It leaves a white corrosive bloom on stone, grout and finished timber, pits aluminium door thresholds, and holds moisture against whatever it is sitting on. Mop the first metre inside the door with clean water weekly through winter rather than waiting for the marks.
