Leak to dry to treated, one company in Hornsey

Hornsey's housing stock is dominated by Victorian and Edwardian terraces, many long since split into flats, alongside period conversions near Priory Park and Hornsey Vale and interwar semis towards Muswell Hill. This mix of shared freeholds, ageing pipework and rear-extension flat roofs means hidden leaks often travel between floors and neighbouring properties before anyone notices.

Areas of Hornsey we cover

We attend leaks right across Hornsey and its neighbourhoods, including:

Common leaks in Hornsey homes

Converted terraces with bathrooms stacked above living rooms

Many Hornsey terraces were divided into upper and lower flats decades ago, placing bathrooms directly above kitchens or lounges below. Perished shower seals, cracked grout or a failed waste pipe under the bath can send water seeping through the joists unnoticed, showing up as a ceiling stain or bulging plaster in the flat beneath long after the leak began.

Flat-roofed extensions and loft conversions

Rear kitchen extensions and loft conversions are common across Hornsey's Victorian terraces, and many rely on flat roofing that degrades with age. Perished felt or cracked asphalt allows rainwater to track along joists and down internal walls, often surfacing well away from the actual entry point, so damage can be developing inside the structure before any visible sign appears indoors.

Ageing plumbing runs in unmodernised properties

A number of Hornsey's older terraces and converted flats still have original or partially updated pipework, including sections that have not been replaced since earlier renovations. Corroded joints, failed compression fittings or a hidden pinhole leak under floorboards can release water gradually into voids and subfloors, causing hidden rot and damp patches to develop before residents are aware there is a problem.

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.
