Cabinet & Letterbox Lock Services — What to Expect
Mailbox and letterbox locks are small, but a communal mailbox bank that's stopped working properly is a genuine problem for a block of flats — post building up, a unit that won't lock, or a key that's gone missing without anyone knowing whose box it belonged to. We can attend a block as a single call-out and work through the affected units, repairing or re-keying as needed.
On individual properties, front door letterbox locks are a smaller but similar job — usually a quick fitting or repair rather than anything involved.
Away from front doors, cabinet, cupboard, filing cabinet and desk locks come up regularly for both homes and small businesses. These tend to be straightforward fits using standard small-format locks, and where an office has several pieces of furniture, we can often set them up to share one key rather than juggling several.
Most jobs in this category are completed the same visit, with the price confirmed before we start.
Blocks of flats in particular benefit from having every mailbox unit checked in one visit rather than waiting for each resident to report a problem individually — it's usually more efficient for a managing agent to arrange one call-out covering the whole bank than several separate ones.
For homes, a letterbox lock is a small but sometimes overlooked security point, particularly on doors where post is pushed straight through into a hallway. Fitting a simple lock or guard is a quick, low-cost addition alongside any other lock work being carried out.
Office cabinet and desk locks tend to fail quietly — a drawer that's always been a little stiff, or a key that's been missing for months with nobody quite sure which unit it belonged to. These are usually quick, inexpensive fixes once we're on site, and we're happy to look at several pieces of furniture in one visit rather than booking a separate call-out for each item.
