Leak to dry to treated, one company in Blackfriars

Blackfriars mixes Victorian and Edwardian former warehouses converted to flats, mansion blocks along the river, and dense post-war and modern developments near the Thames. Converted commercial buildings often carry ageing flat roofs and retrofitted plumbing never designed for continuous residential use, while riverside blocks face constant damp pressure, making hidden leaks from failed seals and pipework a persistent and costly problem.

Common leaks in Blackfriars homes

Converted warehouse flats with ageing flat roofs

Many Blackfriars conversions sit under original flat roofs adapted decades ago for residential use. Membranes and flashings degrade quietly, letting water track along joists and down internal walls far from the original entry point. Residents often notice only a ceiling stain long after the roof covering first failed, by which point timber and insulation beneath have already absorbed significant moisture.

Ensuite bathrooms leaking into flats below

Riverside and mansion block conversions frequently squeezed ensuite bathrooms into upper floors during refurbishment, with shower trays and waste pipes sitting above living rooms in the flat below. Perished seals around trays or failed pipe joints let water seep steadily through floor voids, often surfacing as a damp patch or bubbling paint in a neighbour's ceiling well before the leak is traced back.

Failed plumbing in dense mixed-use buildings

Blackfriars' many mixed-use buildings combine commercial ground floors with residential upper storeys, meaning ageing risers and shared pipework serve multiple uses under varying pressure. Escape of water from a corroded joint or split pipe can travel through service ducts and between units unnoticed, affecting several flats before anyone realises the source lies several floors above the visible damage.

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.

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.
