£180 for up to one hour. In a flat this is the service that decides whether you are dealing with the building's mice or only your own.
£180, covering up to one hour of work on suitable small holes. A separate service from treatment, not included in the £190 or £240 price.
If mice are in the property right now, proofing is not what to book first — treat, then proof.
In a house, proofing keeps mice out of your building. In a flat it does something subtly different and arguably more valuable: it separates your property from the building.
A block is threaded with pencil-width openings — around every pipe and cable entering your flat, at the front door threshold, behind the kitchen units where the void runs on, in the ceiling where a light fitting penetrates. Mice in the communal structure use those to get into individual flats.
You cannot fix the building. You can make your flat a considerably worse option than the one next door, and that is what £180 buys.
| Your situation | What you need | Price |
|---|---|---|
| Droppings or noises now | Treatment first | £190 / £240 |
| Problem dealt with, want to prevent a repeat | Proofing | £180 |
| Active problem and obvious gaps | Both, treatment first | £370 / £420 |
| Mice every winter in the same flat | Both, and be thorough | £370 |
| Just moved in, block has a history | Proofing | £180 |
Sealing a property with mice inside does not remove them. It shuts them in, and a trapped mouse gnaws — in a kitchen or under a floor that frequently means cabling.

View Mouse Control Wealdstone →Mice get through smaller gaps than rats, so a property proofed against rats is not necessarily proofed against mice — the rat work may have closed the 20mm openings and left the 7mm ones.
Proofing done to a mouse standard generally excludes rats as well. Tell us which you are dealing with.
Two cautions. Expanding foam alone is not proofing — mice chew straight through it. And identifying which gaps matter is most of the skill: a property has dozens and only a few are in use.
£180 once against a second treatment plus tenant disruption. Combined figures — £370 flat, £420 house — published so it can be authorised without a quotation stage.
For a flat in a block you also own or manage, proofing several units is worth discussing as one job rather than separately.
Read nextHow Much Does It Cost to Get Rid of Mice in Wealdstone? →No. Treatment is £190 flat or £240 house; proofing is a separate £180.
You are told before the work, not after on an invoice.
Not on a single flat's instruction. That is a matter for the freeholder or managing agent — but tell them we said so, because it is frequently where the problem lives.
Sealed openings stay sealed. Buildings move and get altered, so no proofing is permanent.
One more published price — wasp nest treatment in Wealdstone is £90 fixed cost, guaranteed.
£180 for up to one hour on suitable small holes.
It separates your property from the building. You cannot fix the block, but you can make your flat much harder to enter.
No, it is a separate service.
After. Sealing mice inside makes things worse.
£370 for a flat and £420 for a house.
No. Mice chew through foam — it needs a chew-resistant material behind it.
Not on a single flat's instruction. That is for the freeholder or managing agent.
No, and nobody honestly can about a building.
Tell us what is happening now and whether you are in a flat — it changes what is worth doing.
