How to Handle a Leak in a Rental Property

# How to Handle a Leak in a Rental Property

A leak is the single most common emergency a landlord faces — and one of the most expensive when handled badly. Speed, sequencing, and documentation determine whether it costs £200 or £20,000.

Step 1 — Immediate triage (within minutes)

When the tenant reports a leak:

1. Acknowledge by phone or text within minutes.
2. Tell the tenant to isolate water at the stopcock.
3. Switch off electricity at the consumer unit if water is anywhere near sockets, light fittings, or the consumer unit itself.
4. Move possessions and lift carpets where possible.
5. Place buckets and towels.

If you cannot get a plumber on site within an hour and the leak is active, instruct the tenant to call the water company''s emergency line for a mains shutoff at the boundary.

Step 2 — Dispatch a plumber

Use your vetted on-call contractor. Confirm:

• Arrival ETA in writing.
• Pre-agreed authorisation limit (£200–£500 covers most fixes).
• Brief: identify source, stop the leak, document.

Step 3 — Identify and fix the source

Common causes:

• Failed flexi hose (under sinks, washing machine).
• Burst pipe (winter frost).
• Leaking radiator valve.
• Failed toilet flush valve.
• Shower tray or bath seal failure.
• Roof leak after storm.
• Neighbour''s flat above (leasehold flats — escalate to managing agent immediately).

Fix the source first. Cosmetic repairs come later.

Step 4 — Dry properly

This is where most landlords cut corners — and where mould is born.

• Run dehumidifiers continuously for 5–14 days depending on damage.
• Lift wet carpet/underlay; dry separately or replace.
• Strip wet plaster if it is bowed or blown.
• Open cabinets, drawers; lift skirting if water tracked behind.
• Run air movers (fans directed at wet surfaces).
• Hire from local plant hire: dehumidifier + air mover £30–£60/day.

Use a moisture meter. Do not redecorate until readings are below 16% in wood and 1% in plaster.

Step 5 — Insurance

Most landlord buildings policies cover escape of water (sudden, accidental). Most exclude gradual deterioration.

• Notify insurer within 48 hours.
• Loss adjuster may attend for claims >£2,500.
• Photograph everything before drying-out work changes the scene.
• Keep contractor invoices.
• Expect excess £150–£500.

For contents (tenant''s), tenants need their own policy. Document but do not promise reimbursement for items not your responsibility.

Step 6 — Redecorate

Only after fully dry:

• Replaster if needed.
• Mist coat new plaster.
• Two coats of paint.
• Replace skirting / flooring as needed.

Step 7 — Follow up

• 4 weeks — inspect for damp patches, smell, mould spots.
• 12 weeks — full inspection, moisture meter readings.

Awaab''s Law makes follow-up part of your legal duty for any case involving damp risk.

Documentation for every leak

• Time/date of report.
• Time/date of acknowledgement.
• Contractor instructed, arrival time, work done.
• Photos at each stage.
• Drying-out plan and readings.
• Insurance claim reference.
• Tenant communications.
• Follow-up notes.

Leasehold flats — the upstairs leak

If the source is a flat above:

1. Document immediately — photos, video, neighbour''s flat number.
2. Notify your managing agent / freeholder.
3. Notify your insurer.
4. Pursue the upstairs leaseholder via their insurance (escape of water).
5. Mitigate as if it were your own leak — drying, repairs, tenant care.

Recovering from the neighbour can take months. Do not delay your tenant''s repairs waiting for it.

Common mistakes

• Sending a handyperson to a plumbing job — fix fails, water returns.
• Skipping the drying-out stage — mould appears in 3–4 weeks.
• Repainting too soon — flaking, salt blooms, repeat work.
• Not informing the insurer in time — claim refused.
• Ignoring the tenant''s damaged possessions — relationship damage even if not legally yours to pay.

Bottom line

The leak itself is rarely the expensive bit — slow drying, premature redecoration, and missed follow-ups are. Treat every leak as a multi-week process, not a single visit.
