How do I know if my shower is leaking into the flat below?
Damp patches on the ceiling below after your shower, brown stains around light fittings below, musty smell in your bathroom. In London flats, you are liable for fixing shower leaks into the flat below under the Landlord and Tenant Act. Call us for same-day investigation.
Why is my shower tray leaking?
Most common causes: failed silicone sealant around the tray perimeter (cracks faster in London's hard water), cracked tray (inadequate support), or failed waste seal between the waste body and tray base.
Why is my shower screen leaking at the bottom?
Almost always the bottom door sweep (the rubber strip along the door bottom). Limescale deposits in London's hard water prevent a clean seal. Sweep replacement: £75–£120 fitted. If the frame meets the tray rather than the door, the frame silicone has failed.
Can I reseal a shower tray myself?
Yes, but prep is critical: remove ALL old silicone completely, clean with white spirit, allow 24hrs to dry. Use hard-water-formulated mould-resistant sanitary silicone. Poor prep is the most common cause of failed DIY resealing. We do it right first time.
My shower valve is dripping when off — is it the cartridge?
Almost certainly. London hard water (280–320 mg/l) accelerates cartridge wear as limescale scores the ceramic disc faces. Cartridge replacement costs £120–£220 depending on the valve brand. Most concealed valves allow cartridge access without opening the wall.
