Flooding Emergency across London

Drain flooding is urgent. Blocked gullies may be pushing water towards your London property. A full blockage may have flooded the inside. Either way, request a quote online and we will arrange for an engineer to attend. We cover all 32 London boroughs.

We bring pumping equipment to clear standing water. We also bring high-capacity jetting to clear the blockage that caused the flood.

After the flood, we can give you a record of the conditions, the cause and the repair work, in a format that suits insurance claims. If you need to claim on a buildings or contents policy for water damage, you then have the papers ready.

Sometimes the blockage sits in a Thames Water sewer or a shared private sewer. In that case, we provide CCTV evidence and reports to support a claim for costs against the water company. Each visit ends with a flow test and advice on how to stop it happening again.

While you wait for us, take simple safety steps. Move valuables to higher ground and keep away from electrics near the water. Stop using drains where you can. These steps limit damage, yet they do not replace a proper clearance.

Flooding Emergency — frequently asked questions

Is London drain flooding covered by my home insurance?

It may be. Flooding from a blocked drain can fall under your buildings or contents insurance, especially if water damaged the inside of your home. Report the damage to your insurer promptly, and keep records of the cause. Our job report can serve as evidence of the blockage and the clearance.
