Leak to dry to treated, one company in Park Royal

Park Royal's housing sits alongside one of Europe's largest industrial estates, mixing 1930s semis and terraces in Harlesden and Alperton with ex-council low-rise blocks, canal-side flat conversions and newer developments rising near Old Oak Common. This blend of ageing interwar plumbing, flat-roofed extensions and industrial-to-residential conversions creates varied, often hidden, routes for water to penetrate unnoticed.

Common leaks in Park Royal homes

Flat roofs on extensions and conversions

Many Park Royal properties, particularly 1930s semis in Alperton and Harlesden with rear extensions, rely on flat roofs that were never designed to last indefinitely. Felt and asphalt coverings degrade with age and weather exposure, letting water seep gradually into joists and ceilings below. Because the entry point is often metres from the eventual stain, damage can spread through loft insulation and timber for months before it becomes visible indoors.

Bathrooms leaking into flats and rooms below

Converted properties and ex-council blocks around Stonebridge and Craven Park often stack bathrooms above living spaces with ageing shower trays, grout and pipework. Once seals around baths or waste pipes perish, water tracks along floor joists or through concrete slabs into the ceiling of the flat or room beneath, frequently surfacing as a stain well away from the original leak, delaying diagnosis and allowing damp to establish.

Perished seals and failed plumbing in older stock

The interwar terraces and semis common around Twyford Abbey and Hanger Lane still carry original or mid-life plumbing runs, with washers, compression joints and mastic seals around baths, sinks and stopcocks reaching the end of their working life. These failures tend to release water slowly behind cabinetry or under floorboards, so the escape of water goes unnoticed until skirting boards swell or a musty smell develops.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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.
