Leak to dry to treated, one company in Northwood

Northwood's housing stock is dominated by large 1920s and 1930s mock-Tudor and mock-Georgian detached and semi-detached houses, many extended over the decades with flat-roofed rear additions and converted lofts. Around Moor Park this extends to substantial executive homes with multiple bathrooms. These older properties, plus ageing extensions, mean ample scope for perished seals, tired flat roofing felt and long-buried plumbing runs to fail unnoticed.

Common leaks in Northwood homes

Flat-roofed extensions leaking into ceilings

Many Northwood houses gained kitchen or utility extensions during the 1960s to 1980s, most topped with felt or asphalt flat roofs. As these coverings age they crack, blister or pull away at the upstands, letting rainwater track along joists before it shows as a ceiling stain. Because the leak point is often metres from the visible damp patch, owners frequently underestimate the timber and insulation damage already done underneath.

First-floor bathrooms soaking ground-floor rooms

The larger period homes around Northwood and Moor Park typically have bathrooms and en-suites added above kitchens or reception rooms. Perished shower tray seals, cracked grout or a failed waste pipe joint under the floor let water travel silently through joists, reappearing as bubbling paint or a sagging ceiling well below the original fault. By the time it is spotted, insulation and plasterboard have usually been soaking for some time.

Hidden pipework failures in older properties

Homes built between the wars and later extended often mix original lead or copper pipework with newer plastic runs, buried under solid floors or within stud walls. Corrosion, frozen sections in harder winters, or a poorly soldered joint can cause a slow escape of water that seeps through screed for weeks before damp patches or a rising water bill give the game away, by which point flooring and skirting are often ruined.

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.
