Leak to dry to treated, one company in Angel

Angel's housing stock ranges from Georgian and Victorian terraces on Duncan Terrace and Colebrooke Row, now split into flats, to 1960s and 70s estates such as Packington, plus newer canal-side developments near City Road Basin. This mix means old lead and cast iron pipework sits alongside flat roofs and stacked conversions, each prone to its own type of hidden water leak.

Areas of Angel we cover

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

Common leaks in Angel homes

Shared risers in converted terraces

Many Georgian and Victorian houses around Barnsbury and Canonbury were divided into flats decades ago, with plumbing risers buried in party walls serving several units. A failed joint or corroded section can leak steadily behind plaster for months, tracking down between floors before it surfaces as a stain in a neighbour's flat below, often far from the actual source.

Flat roofs on estates and mansion blocks

Packington Estate and several mansion blocks off Essex Road rely on flat roofing that perishes with age and weather cycling. Once the felt or asphalt cracks, rainwater seeps through the deck and travels along joists before dripping into top floor ceilings, meaning the visible damp patch is rarely directly beneath the actual breach in the roof covering.

Stacked bathrooms leaking through floors

In converted townhouses near Upper Street, bathrooms are frequently stacked directly above one another to simplify plumbing runs. Perished sealant around baths and shower trays, or a cracked waste pipe under the floor, lets water escape into the ceiling void below, gradually soaking joists and plasterboard until it appears as a bulge or brown mark in the flat underneath.

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.
