Damp, mould & leak services in Hillingdon

Hillingdon's stock ranges from 1930s Metroland semis in Ruislip and Northwood to interwar and postwar terraces in Hayes and Yiewsley, plus flat conversions near Uxbridge town centre and low-rise estates close to Heathrow. Solid brick cavity walls, original crittall windows and ageing pebbledash render are common, and proximity to the Rivers Colne, Pinn and Crane leaves many properties prone to rising damp and slow-drying groundwork after wet weather.

Common damp problems in Hillingdon homes

Metroland semis in Ruislip and Northwood

Many 1930s semis here retain original solid or early cavity walls with shallow foundations and short front gardens laid to pebbledash. Render that has cracked or blown traps moisture against the brickwork, causing rising damp in hallways and bay-window rooms. Ineffective or missing damp-proof courses, common in unmodernised examples, allow salt staining and mould to develop along skirting boards and behind fitted furniture.

Terraced and ex-council housing in Hayes and Yiewsley

Hayes and Yiewsley have a large stock of interwar and 1950s-60s terraces and former council houses, many now under-insulated after loft conversions or replacement windows were fitted without upgrading ventilation. This traps humid air, leading to persistent condensation and black mould on north-facing bedroom walls and around window reveals, particularly in properties near the Grand Union Canal where ground moisture is already higher.

Flat conversions and flood-prone areas near Uxbridge and Heathrow

Uxbridge town centre has numerous Victorian and Edwardian houses split into flats, where shared guttering, flat roof extensions and neglected soil stacks often go unmaintained by absentee landlords, causing hidden leaks into ceilings below. Meanwhile low-lying areas towards Heathrow and West Drayton, close to the River Colne floodplain, see recurring penetrating damp in ground-floor rooms after heavy rainfall due to poor surface drainage.

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.
