Leak to dry to treated, one company in St Mary Cray

St Mary Cray's housing stock runs from Victorian terraces around the High Street and River Cray to 1930s semis, post-war council-built estates near Cotmandene Crescent and Ruxley, and newer flat conversions close to the station. This mix of ageing lofts, extended kitchens and river-adjacent gardens means old pipework, flat-roof extensions and converted upper floors are common, each a route for hidden water to travel unseen into the property below.

Common leaks in St Mary Cray homes

Flat-roof extensions over kitchens and bathrooms

Many St Mary Cray terraces and semis near the High Street have had rear kitchen or bathroom extensions added under flat roofs, often with felt or older asphalt coverings. Once the membrane perishes or flashing pulls away at the wall junction, water tracks along joists rather than dripping straight through, so damp patches and ceiling staining can appear well away from the actual leak point.

Converted flats and maisonettes with shared plumbing runs

Around Poverest and the streets near St Mary Cray station, older houses split into flats share soil stacks, waste pipes and bathroom risers boxed into party walls. A failed joint or perished seal in an upper flat's bathroom can send water down through ceiling voids into the flat below, often surfacing as a stain days after the original escape of water occurred.

River Cray proximity and ground movement affecting pipework

Properties close to the River Cray and its floodplain in St Mary Cray sit on ground prone to seasonal movement, which can stress buried supply pipes and drainage joints over time. Combined with ageing copper and lead plumbing in older terraces, this creates conditions for slow, hidden leaks under solid floors that go unnoticed until skirting boards or flooring begin to lift.

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.
