Water damage restoration covers everything that happens after a flood, burst pipe, sewage backup, or leaking roof: extracting standing water, drying out floors and walls, removing damaged materials like carpet or plasterboard, and treating the site to stop mould before it starts. In London, this often means dealing with older building fabric, basement flats prone to water ingress, and terraced houses where a leak in one property can quickly affect a neighbour's. We've listed 30 companies across the city that handle this work, from small local outfits to larger emergency response teams.
What to look for
Response time matters more than almost anything else in this trade. Water sitting for 24-48 hours is what turns a drying job into a mould remediation job, so ask how fast a crew can actually get to your property, not just what their advertised call-out time is. Beyond speed, check whether they use moisture meters and thermal imaging to confirm a space is properly dry (not just surface-dry), whether they work directly with insurers and can produce documentation for a claim, and whether they carry proper liability insurance. Get a written scope of work before anything is ripped out.
How we rank them
Our scoring looks at response speed, the range of services offered (extraction, drying, mould treatment, structural repair), customer feedback patterns, and how transparent each company is about pricing and process.
