Common Bathroom & Kitchen Leak Sources

⚠️

Water stains on the ceiling below

Brown stains directly under a bathroom or kitchen mean water is coming through the floor. It could be from the shower tray, bath seal, sink waste, or supply pipes. The stain location gives clues.

⚠️

Damp or soft flooring

Spongy vinyl or laminate near the bath, shower, or sink suggests water is getting underneath. Long-term exposure rots the subfloor. The source is usually failed sealant or a leaking waste.

⚠️

Mould around grout lines

Black mould in grout joints or at the base of tiles means water is sitting there. If grout has failed, water can get behind tiles and into the structure, causing hidden damage.

⚠️

Musty smell in cupboards under sinks

That damp smell under the kitchen or bathroom sink means water has been leaking there for a while. Check all waste connections and supply pipes, something is dripping.

⚠️

Pooling water with no obvious source

Water appears on the floor but you can't see where it's from. It might be splash from the shower escaping past a faulty screen, or water running along a surface from a failed seal elsewhere.

How We Find Bathroom & Kitchen Leaks

1

Inspect all visible connections

We check under sinks, behind toilets, around the bath panel, and all exposed pipework. Many leaks are visible once you know where to look, a drip from a waste pipe or a weeping compression joint.

2

Test seals and grout

We check the sealant around baths, showers, and sinks for gaps or perishing. We inspect grout for cracks. We sometimes run water and watch where it escapes, this reveals failed waterproofing.

3

Water testing

For shower leaks, we block the waste and fill the tray with water. If the ceiling below gets wet, the shower tray or waste is leaking. If not, it's a sealant or grout issue.

4

Thermal imaging (if needed)

For hidden leaks behind tiles or under floors, thermal imaging shows us where moisture has accumulated. This pinpoints the problem area without removing tiles unnecessarily.

5

Repair at source

Once found, we fix it properly. That might mean re-sealing, re-grouting, replacing a waste trap, tightening a connection, or replacing a damaged section of pipe. We test thoroughly afterward.

Typical Leak Sources We Fix

Failed shower tray seal

The sealant between the shower tray and the wall perishes over time. Water runs down the wall, behind the seal, and through the floor. A full re-seal stops it.

Cracked grout in showers

Grout is porous and cracks with movement. Water gets behind tiles and soaks into the plasterboard or floor structure. Re-grouting and sealing is essential to prevent rot.

Leaking bath overflow

The overflow pipe connection inside the bath can work loose or perish. When the bath fills past the overflow, water leaks into the wall cavity instead of draining safely outside.

Sink waste leaks

The waste trap under the sink can crack, or the compression fittings can loosen. Water drips into the cupboard below, rotting the base. Check and tighten or replace the trap.

Appliance hose connections

Washing machines and dishwashers have supply and waste hoses that can split or work loose. A small leak behind a washing machine can go unnoticed for months until the floor fails.

Preventing Future Leaks

1

Re-seal baths and showers annually

Silicone sealant perishes with heat and moisture. Cut out the old sealant and apply fresh every 12-18 months. It's a 30-minute job that prevents thousands in water damage.

2

Check under sinks regularly

Once every few months, clear out the cupboard and check for dampness or drips. Catch slow leaks early before they cause rot. Tighten any weeping connections.

3

Don't ignore cracked grout

If you see cracks in shower grout, re-grout it immediately. Water behind tiles causes rot, mould, and structural damage. A £10 tube of grout saves thousands in repairs.

4

Replace appliance hoses every 5 years

Washing machine and dishwasher hoses perish over time. Replace them every 5 years even if they look fine. Braided stainless steel hoses are far more reliable than rubber.
