Damp, mould & leak services in Hanwell

Hanwell's housing spans Victorian and Edwardian terraces around Church Road and Golden Manor, the early 1900s Cuckoo Estate's Arts and Crafts cottages, interwar semis near Elthorne Park and Greenford, and postwar council blocks off Uxbridge Road. Solid brick walls without cavities, ageing render, and proximity to the Brent River and Grand Union Canal combine to make rising damp, penetrating damp and condensation persistent problems across the area.

Common damp problems in Hanwell homes

Rising and penetrating damp in Church Road's Victorian terraces

Many Victorian and Edwardian terraces around Church Road and Golden Manor were built with solid brick walls and shallow, often failed, slate damp proof courses. Decades of external ground level rising above these courses, combined with repointing using hard cement rather than lime mortar, trap moisture in the brickwork. This shows up as tide-marked skirting, crumbling plaster and persistent mould in ground floor rooms year round.

Condensation issues in the Cuckoo Estate's cottage homes

The Cuckoo Estate's early twentieth century Arts and Crafts style cottages have solid walls, small original windows and shallow eaves, features prized for character but poor for ventilation. Many now have double glazing fitted without adequate trickle vents, so everyday moisture from cooking, bathing and drying clothes has nowhere to escape. Black mould commonly develops in corners, behind wardrobes and around window reveals in these homes.

Wall tie failure and flat roof leaks in Elthorne Park's semis

The 1930s semi-detached houses near Elthorne Park and towards Greenford typically have cavity walls, but their original steel wall ties have corroded with age, causing cracking and allowing water to bridge into internal walls. Many owners have also added flat roof rear extensions that were never designed for a hundred years of British weather, and failing felt coverings now let water track down into ceilings and party walls unnoticed for months.

What our customers say

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
