Lock & Door Maintenance London. Prevent Problems Before They Start.

Scheduled & reactive maintenance for locks, doors and access hardware across London, residential & commercial. Catch faults early, cut emergency callouts and extend the life of your hardware.

Lock and door maintenance in London

Most locksmith callouts are avoidable. Stiff locks, seized mechanisms, dropping UPVC doors, and worn cylinders all give warning signs long before they fail completely, but those signs are easy to miss until you're locked out at midnight or facing a security audit you can't pass.

We provide scheduled and reactive maintenance for locks, doors, and access hardware across London for both residential and commercial clients. A routine maintenance visit catches problems early, extends the life of your door hardware, and keeps you compliant with insurance and tenancy requirements, at a fraction of the cost of an emergency repair.

What a Maintenance Visit Covers

A full inspection and service of every lock, door and access mechanism on the property.

Lock inspection and lubrication

Lock Inspection & Lubrication

We inspect every lock, clean the internal mechanisms and apply the correct dry or graphite lubricant, never WD-40, which attracts dirt and damages components over time. A properly lubricated lock operates smoothly and is far less likely to seize.

Cylinder condition check and replacement

Cylinder Condition Check & Replacement

We assess every euro cylinder, mortice lock and Yale-style nightlatch. Cylinders showing wear, corrosion or pick damage are flagged, and we check whether they meet current British Standard and insurance requirements.

UPVC and composite door mechanism service

UPVC & Composite Door Mechanism Service

We check that multipoint gearboxes, handles, hinges and keeps all engage correctly and operate smoothly under load. Minor adjustments during a visit prevent the costly gearbox replacements that follow ignored wear.

Door alignment and hinge adjustment

Door Alignment & Hinge Adjustment

Doors that drag, stick or no longer sit flush strain the locking mechanism and signal hinge wear or frame movement. We realign doors and tighten or replace hinges to restore smooth operation and reduce mechanism stress.

Door closer inspection and adjustment

Door Closer Inspection & Adjustment

For overhead closers on fire doors, communal entrances and commercial premises, we check for hydraulic leaks, closing speed and latching action, and adjust or replace as needed. A closer that doesn't fully shut is a safety and security liability.

Security hardware assessment

Security Hardware Assessment

We assess external doors and ground-floor windows for vulnerabilities, outdated cylinders, missing anti-snap protection, inadequate keeps, or bolts that don't meet modern standards. You get a written report with prioritised recommendations, not a sales pitch.

Why Regular Maintenance Pays Off

For homeowners and landlords, regular lock maintenance delivers three clear benefits:

Insurance compliance

Many home and landlord insurance policies require external doors to be fitted with locks meeting BS 3621 or equivalent standards. A maintenance visit identifies any locks that fall short - before a claim is refused, not after.

Tenancy obligations

Landlords have a legal duty to ensure rental properties are secure and that door hardware is in good working order. Documenting regular maintenance visits also provides a paper trail of compliance if a dispute arises.

Avoiding emergency callouts

The most common residential emergencies, such as lockouts, seized locks, failed UPVC gearboxes, are typically the result of gradual wear that went unnoticed. A single annual maintenance visit costs far less than a late-night emergency repair.

We offer one-off maintenance visits and can arrange annual scheduled visits for landlords managing multiple properties, with consolidated invoicing and priority response for any reactive callouts between visits.

Why Choose 24hrslocksmith for Maintenance?

We fix problems, not just report them

Our visits aren't inspections followed by a quote sheet. Where parts are needed that we carry on the van, we fit them on the same visit. You leave with a fully functioning, secure property - not a to-do list.

Written report provided

After every visit you receive a written summary of what was inspected, what was done and any further recommendations, useful for landlord records, insurance documentation and facilities management.

No upselling

We'll tell you if a lock needs replacing. We'll also tell you if it doesn't. Our business is built on repeat clients and referrals, not one-off jobs inflated by unnecessary work.

DBS-checked engineers

Every technician has passed an enhanced background check - ideal for residential properties and sensitive commercial environments.

12-month warranty on all parts fitted

Any lock, cylinder or mechanism we install during a maintenance visit is covered for parts and labour for a full year.

Available 24/7 for reactive follow-ups

If something fails between scheduled visits, we respond as a priority.

Frequently Asked Questions

How often should locks be serviced or maintained?

For most residential properties, an annual maintenance visit is sufficient. High-use commercial doors, such as main entrances in office buildings or retail units, benefit from a check every six months. UPVC door mechanisms in particular are worth inspecting annually, as gearbox wear is gradual and easy to miss until complete failure occurs.

Can you maintain locks without replacing them?

In most cases, yes. Cleaning, lubricating and adjusting existing locks extends their service life significantly. We only recommend replacement when a component is genuinely at the end of its useful life or no longer meets security standards.

Do landlords have to maintain door locks?

Yes. Landlords in England are legally required under the Landlord and Tenant Act 1985 to keep the structure and exterior of a property in repair, which includes external doors and their hardware. Many letting agents and property managers arrange annual locksmith maintenance visits as a standard part of their tenancy management process.

What's the best lubricant for door locks?

A dry PTFE or graphite-based lubricant is correct for most pin tumbler and euro cylinder locks. Avoid WD-40 or oil-based products - they provide short-term relief but attract dust and gum up the mechanism over time, accelerating wear. We use the correct lubricant for each lock type during our maintenance visits.

Can you service UPVC door mechanisms as part of a maintenance visit?

Yes. UPVC multipoint locking mechanisms, hinges, handles and keeps are all included in our door maintenance service. Gearbox lubrication and hinge adjustment are the most common UPVC maintenance tasks and significantly extend the life of the mechanism.

Do you offer maintenance contracts for landlords with multiple properties?

Yes. We offer scheduled maintenance arrangements for landlords and property management companies managing multiple properties, with priority response for reactive callouts and consolidated invoicing. Contact us to discuss your portfolio.

How much does a locksmith maintenance visit cost in London?

Cost depends on the number of doors and locks to be inspected and any parts required. We provide a fixed quote before starting work. Call us on +44 2030 538733 for an estimate based on your property.

Do you work outside London?

Our primary coverage area is Greater London and surrounding areas including Essex, Kent, Surrey and Hertfordshire. For larger commercial projects we can travel further - contact us to discuss your location.

What happens if my staff member left with a key?

This is one of our most common commercial callouts. We recommend either rekeying the existing lock (cheaper, if the lock is compatible) or replacing the cylinder entirely. We can advise on which is appropriate and attend within the hour in most London locations.
