A flat only a few years old, with sealed windows and a fitted kitchen, looks like the last place a mouse could get into, and finding droppings behind the kickboard comes as a genuine shock. The explanation is usually the building's own plumbing: every block has vertical shafts carrying pipes and cables from the car park to the top floor, and a shaft like that is warm, dark and continuous.
Mouse control is £190 for a flat and £240 for a house. Book a mouse visit on this page, or call 0800 955 2347.

Think of a modern block as a set of homes threaded onto a few vertical services. Soil stacks, water pipes, heating flow and return, electrical containment and data cabling all have to run from the bottom of the building to the top, and they pass through every floor on the way.
That locked cupboard on the corridor is where those services pass from one level to the next. Each pipe goes through a hole in the floor slab, and where the sealing around it was never finished, or was cut through by a later trade fitting something else, the shaft becomes a staircase that no door on your landing controls. It also explains why two flats on different floors can start hearing the same thing within a week of each other — can mice travel between flats? covers that pattern.
Where the services arrive inside your flat they are hidden again: a boxed corner in the bathroom, a duct behind the utility cupboard, the holes cut for the sink waste and the washing machine. A fitted kitchen then adds a continuous void behind and beneath the units, closed off by a clip-on plinth that hides everything at floor level. Mice behind kitchen units describes what tends to be found back there.
Those are the rooms where it usually starts. A cycle store holds cardboard, bags and things left for months; a bin store holds the food. A mouse settled in either is already inside the envelope of the building and only needs the first warm route upwards, which is generally the riser or a service duct beside it.
Away from the new blocks the story flips. These houses have suspended timber floors, party walls that were never sealed where the joists bear into them, and a kitchen or bathroom that has been replaced at least once, each time leaving a redundant hole behind. Flats above shops sit on top of a food business with its own service runs. How mice get into a house runs through those openings in order of likelihood.

The signs of mice takes each of those further. Larger tapered droppings, or gnawing heavy enough to damage a door, mean rat control in Alperton instead, and where mice nest shows the places worth opening up first.
Say whether it is a flat in a block, a flat above a shop or a whole house, which floor you are on, which rooms the droppings are in, and whether anyone else in the building has reported the same thing. Mention any recent works in the block, because a stripped-out flat or a new service run tends to be what moved them along.
Empty the cupboard under the sink and the food cupboards, and clear enough floor in front of the units for the plinth line to be reachable. Afterwards you will hear what was found and what to watch for; the time it takes depends on the building and on what is happening in the flats around you, as how long mouse treatment takes explains. Get in touch again if droppings reappear after a quiet spell.

Inside your own front door the list is short and worth doing properly: the holes around the sink and washing machine waste, the top and bottom of any pipe boxing, the gap behind the plinth and the threshold of your entrance door onto the corridor. Small reachable openings like those are what rodent proofing in Alperton closes, and mouse-proofing a property covers the method. The riser, the corridor and the stores are the building's to deal with, and a block where only one flat is ever treated keeps the problem circulating — much of why mice keep coming back. For the borough-wide page see Mouse Control Brent; neighbouring Wembley deals with the same kind of new-build kitchen.
Treatment deals with the mice and leaves the hole around the sink waste exactly as it was, which is what rodent proofing is for — small accessible gaps, £180 for up to one hour.
Mouse control in Alperton is £190 for a flat and £240 for a house. Every self-contained flat is charged at the flat price, whether it is a studio in a new canalside block or a conversion above a shop, and a whole house in the older streets at the house price. What you pay covers the mice in your home; the riser, the corridor and the ground-floor stores are communal and are for the building to arrange.
| Treatment | Price |
|---|---|
| Mouse Control – Flat | £190 |
| Mouse Control – House | £240 |
Age is not much protection. The shafts that carry pipes and cables through a block run past every floor, and a single unsealed penetration in a floor slab is enough. What is newer is usually the hiding place rather than the way in.
No — it is a communal service cupboard, normally locked, and it is not yours to open or to seal. Report what you suspect to the managing agent or freeholder and ask them to have it checked; treatment inside your flat is the part you can book yourself.
Not automatically, but it is the usual starting point in a block, and the distance from there to a kitchen is shorter than it looks. Have the store dealt with by the building, and watch the plinth line and the under-sink cupboard in your own flat.
It gives the better outcome where mice are living in shared voids, because a booking covers the home it was made for. In practice, agreeing timing with the neighbours who are affected, and asking the agent to handle the communal parts alongside, is what stops them shuttling back and forth.
Start at the edges of the ground floor: along the skirting, under the stairs, behind the boiler and in the cupboard where pipes drop into the floor. In an older house the void under the boards connects rooms that appear entirely separate.
It does. Have an electrician look at any damaged cable and stop using the appliance meanwhile. Mice, wiring and pipes explains why this is the part worth acting on quickly.
They can, usually by the same pipe and cable routes they use lower down rather than from the roof. Mice in lofts describes what to look for up there, and if the noise is in daylight it is worth considering squirrel control instead.
