A solid-walled estate house has fewer hidden routes than a newer home, so the gaps rats and mice use are usually ones you can put a finger on: a broken air brick, a hole round a pipe, a worn back door. Closing them is the job that follows treatment.
Rodent proofing is £180 for up to one hour on small holes. Book proofing with the form, or call 0800 955 2347.
Solid brick gives a rodent nothing to run along inside the wall, so it needs a real opening, and after a century most houses have a few. The usual ones are at the back and side, low down, and hidden behind bins, planters or kitchen units. The most common entry points is a good checklist before you walk round the outside.

Where the ground floor is suspended timber, air bricks in the outside wall keep the void beneath it ventilated. They must stay open, but an old grille that has cracked or lost a corner lets a rat or mouse straight under the floor. Stopping rats at air bricks explains how a damaged one can be covered without cutting off the airflow.

Every boiler, washing machine and waste pipe added since the houses were built has meant a hole through the wall, and many were cut wider than they needed to be. Old mortar also wears away at the foot of a wall where rain splashes back off the path. Proofing pipe and utility gaps covers the detail.

A back door that opens onto the garden wears at the threshold, and a gap under it is a straight run in from the path behind the house. Where a kitchen has been extended or a lean-to added, the line where the new work meets the old brick can open up at ground level.
Proofing means fixing things to the building itself, so whoever books needs the right to have that done.
The £180 covers up to one hour of work on small, reachable holes and gaps. On an estate house that might mean covering a cracked air brick, filling round two or three pipe entries and fitting a strip under the back door, depending on how many gaps there are and how easy they are to get at.
Larger repairs are for a builder: repointing a whole wall, replacing a rotten door frame, rebuilding a gap in the party wall in the loft, or reworking a badly built extension joint. You will be told if the house needs that, rather than having it squeezed into the hour. A broken drain is for a drainage contractor, as rats and drains explains.
Seal a gap while rats or mice are still using it and they will chew a new one, or die inside a wall or floor. Book rat control or mouse control first and proofing once activity has stopped; before or after treatment explains the order.
When you book rodent proofing, say whether it was rats or mice, when treatment finished, whether you own or rent the house, and where you think they were getting in. Move bins and planters away from the back and side walls, clear anything stored in front of the back door, and make sure the cupboards under the sink and round the boiler open. Afterwards you will hear which gaps were closed and whether anything bigger needs a builder. If droppings or gnawing appear next to a sealed gap, get back in touch; how to tell which holes are in use helps you judge.

Rodent proofing in Burnt Oak is £180 for up to one hour of work sealing small holes and gaps, at the same price for an estate house or a flat. How much gets done depends on how many gaps there are and how easily they can be reached, and building repairs such as repointing or a new door frame are outside it.

| Rodent Proofing | £180 – up to 1 hour, small holes |
Report the gaps to your landlord first and ask whether it will deal with them, because proofing is work on the building. If it agrees to you arranging it, book and tell us who gave permission.
No. They ventilate a timber floor, and blocking them can lead to damp and rot. A damaged one should be covered or replaced in a way that keeps air moving.
Smaller than most people expect. What size hole a mouse can get through gives the sizes, and the rat equivalent shows why a worn door threshold matters.
Yes. You cannot fence the path off, but you can stop the house being their next step. Proofing closes the ways into the building; tidying the garden and the path does the rest.
They are no substitute for closing gaps. Do ultrasonic repellers work? looks at the question.
A hole in the party wall in the roof space is usually a builder's job, and it affects both houses, so talk to your neighbour. Small gaps round pipes or cables up there may be reachable within the hour.











Tell us whether it was rats or mice, whether treatment has finished, whether you own or rent, and where on the house they were getting in.
