Damp, mould & leak services in Heston

Heston's housing stock is dominated by 1930s semi-detached and terraced houses built around the old village and North Hyde, many extended over the decades with flat-roofed kitchens, garages and loft conversions. Add in postwar infill, converted properties near Heston Road split into flats, and ageing plumbing throughout, and the area has plenty of weak points where water can get in unnoticed.

Common leaks in Heston homes

Flat-roofed extensions on 1930s semis

Many Heston semis have had kitchen or bathroom extensions added with flat felt or asphalt roofs, now decades old. Once the covering perishes or splits at the joints, rainwater tracks slowly along joists and ceiling timbers rather than dripping straight through, so damp patches and sagging plasterboard often appear well after the roof itself has actually failed.

Upstairs bathrooms leaking into rooms below

In older Heston houses and converted properties split into flats, bathrooms are frequently positioned directly above living rooms or kitchens. A cracked shower tray, failed sealant around the bath, or a slow pipe joint under the floor can send water into the ceiling void below for weeks, showing up as staining or bulging plaster long before residents realise there is an active leak.

Perished seals and ageing plumbing in original 1930s homes

A large share of Heston's housing dates from the 1930s expansion around the old village, meaning original pipework, window seals and roof flashings are well beyond their expected lifespan. Perished rubber washers, cracked lead flashing and gaps around soil pipes let water seep in gradually, often escaping notice until skirting boards, floorboards or nearby walls have already absorbed significant moisture.

What our customers say

Excellent
Rated 5.0 / 5 based on 23 reviews on
Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
