Leak to dry to treated, one company in Primrose Hill

Primrose Hill is dominated by grand stucco-fronted Victorian terraces and villas, many long since divided into flats, alongside mansion blocks and mews conversions near Regent's Park Road. This mix of period roofs, shared party walls, multiple bathrooms stacked above one another, and later loft or rear extensions creates plenty of scope for hidden escapes of water between neighbouring properties and flats.

Areas of Primrose Hill we cover

We attend leaks right across Primrose Hill and its neighbourhoods, including:

Common leaks in Primrose Hill homes

Flat roofs and valley gutters on converted terraces

Many Primrose Hill terraces have flat-roofed rear additions or hidden valley gutters between adjoining pitched roofs, often finished in felt or ageing lead. Once these fail, water can track silently along joists and through party walls before appearing as a stain in a completely different room, sometimes in the neighbouring house rather than the one with the actual defect.

Bathrooms leaking through original ceilings

Where grand Victorian houses have been split into upper and lower flats, bathrooms are frequently stacked directly above living rooms in the flat below. Perished shower seals, cracked grout or a failed waste pipe can send water seeping through original lath-and-plaster or later plasterboard ceilings, causing staining and sagging that only becomes obvious once real damage has already occurred.

Perished seals in extensions and lower ground floors

Rear glazed extensions, roof lanterns and lower ground floor flats are common in this area, and each brings its own weak points. Silicone seals around glazing perish with age and London's clay soil movement, while tanking in lower ground bathrooms and kitchens can fail gradually, letting water escape into the structure long before any leak is visible at floor level.

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 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.
