Leak to dry to treated, one company in Canonbury

Canonbury's housing mix runs from grand Georgian and Victorian terraces around Canonbury Square to subdivided flats, mansion blocks and converted basements nearer Essex Road and Balls Pond Road. This blend of period plumbing, shared flat roofs and multiple leaseholds under one roofline means hidden water leaks are a constant risk, especially where original pipework meets modern extensions and loft conversions.

Common leaks in Canonbury homes

Converted Georgian terraces with stacked plumbing

Many Canonbury terraces near Canonbury Square and Compton Terrace have been split into flats over decades, layering new bathrooms and kitchens onto original Victorian and Georgian pipework. Waste stacks and supply pipes often run through party walls and floor voids shared by several leaseholders, so a failed joint or perished washer on an upper floor can travel unseen through ceilings and skirting well before any resident notices.

Flat roof extensions and rear closet wings

Rear additions and closet wing extensions common along streets off St Paul's Road and Essex Road are frequently topped with felt or asphalt flat roofs. These coverings degrade with age and movement in the surrounding brickwork, letting water track along joists into the rooms below. Because the entry point sits above a ceiling void, dampness and staining often appear metres from where the roof membrane actually failed.

Mansion block risers and communal seals

The mansion blocks and larger period conversions around Highbury Fields and Canonbury Park share communal risers, tanks and waste pipes serving multiple flats. Perished seals or corroded joints within these shared runs can leak into wall cavities and floor voids for some time, since no single occupant has full access to inspect them, making the source of a stain in one flat often lie in another entirely.

★★★★★

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.

Keiryn Raf, via Google

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.
