Leak to dry to treated, one company in Holloway

Holloway's housing stock is dominated by Victorian and Edwardian terraces long since converted into flats, sitting alongside 1930s to 1960s council estates and low-rise ex-local-authority blocks. This mix means shared plumbing stacks, stacked bathrooms, and flat roofs on extensions and estate blocks, all of which age unevenly and leave hidden leaks to travel between floors and flats before anyone notices.

Common leaks in Holloway homes

Converted terraces with stacked bathrooms

Many Holloway terraces on streets like those around Hornsey Road and Tollington Road were split into flats decades ago, often with bathrooms built directly above one another. Waste pipes and shower trays installed during these conversions can fail quietly, sending water through floor joists into the flat below, where it surfaces as ceiling staining long after the leak actually began.

Flat roofs on estates and rear extensions

Holloway's council estates and the flat-roofed rear extensions common on its Victorian terraces rely on felt or asphalt coverings that perish with age and weather exposure. Once the membrane splits or blisters, rainwater tracks along joists and inside cavity walls rather than dripping straight through, so damp patches can appear well away from the actual point of failure.

Perished seals and ageing soil stacks

Older converted properties in Holloway still often run on original cast-iron or early plastic soil stacks and waste seals that have hardened and cracked over the years. An escape of water at a joint or seal behind bath panels or under kitchen units can run for weeks unseen in a shared or let property, causing hidden rot and mould before it is finally traced.

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.

Great experience with this company from start to finish. They were professional, knowledgeable, and explained everything clearly without any pressure. The work was carried out efficiently and to a high standard, and we’ve already noticed a big improvement. It’s reassuring to deal with a team that genuinely cares about doing the job properly. Highly recommend to anyone dealing with damp or mould issues.

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.
