Damp, mould & leak services in Cranford

Cranford's housing stock is dominated by inter-war and post-war semi-detached and terraced homes, alongside pockets of low-rise ex-council flats near Cranford Park and later infill housing close to Heathrow. Many properties have had loft conversions, rear extensions and en-suite additions to accommodate airport workers and growing families, each adding pipework, flat roofing and joints that can fail unseen for years.

Areas of Cranford we cover

We attend leaks right across Cranford and its neighbourhoods, including:

Common leaks in Cranford homes

Flat-roofed extensions prone to hidden leaks

Rear kitchen and utility extensions are common across Cranford's semi-detached streets, many finished with felt or GRP flat roofs. Once the waterproof membrane ages or blisters, water tracks along joists and drips well away from the actual breach, soaking ceiling plasterboard and insulation for months before a stain finally appears indoors.

En-suite conversions leaking into rooms below

Loft and box-room conversions into en-suite bathrooms are widespread in Cranford, often built without a proper tanking upgrade beneath the shower tray or bath. Grout and silicone seals perish over time, letting water seep through the floor deck and emerge as damp patches or sagging ceilings in the bedroom or hallway underneath.

Ageing plumbing in inter-war and ex-council homes

A good share of Cranford's 1930s to 1950s housing, including flats around Cranford Park, still runs on original or partially replaced pipework hidden within solid floors and party walls. Corroded joints, perished washers and hairline pinhole leaks under sinks or behind stud walls can escape slowly, causing hidden rot and mould before any visible sign shows.

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.
