🔒 Your details are never shared.
Sludge and scale build up inside heating systems over years, especially in older properties across Wimbledon, Mitcham and Raynes Park that have never been flushed. Here are the most common signs our engineers see.
Cold patches at the bottom of a radiator while the top stays warm is a classic sign of sludge settling inside — bleeding won't fix this, only a flush will.
Radiators that stay cold even after bleeding and checking the valves usually have significant sludge blocking flow, common in the older systems found across Merton's period housing.
Kettling, banging and gurgling noises from the boiler or pipework are often caused by scale and sludge restricting flow and causing localised overheating within the system.
A system clogged with sludge has to work harder to circulate water, reducing efficiency and pushing up running costs even when the boiler itself is working normally.
A thorough, whole-system flush carried out at a fixed price with a full explanation before any work begins.
We check the condition of your system, identify problem radiators, and confirm a power flush is the right fix before recommending it.
A power flushing machine is connected to the system, circulating a cleaning fluid at high flow to break down sludge and scale throughout the pipework.
Each radiator is individually flushed in reverse flow to remove trapped debris, ensuring the whole system is cleared, not just the main pipework.
A corrosion inhibitor is added to protect the system going forward, and the heating is tested to confirm even warmth across every radiator.
Proper water hygiene management protects the people using your building and your legal position as the responsible person.

Three radiators in our Wimbledon house had been cold at the bottom for years. Power flush cleared decades of sludge out completely — heating is even across the whole house now.
Boiler had started kettling and one radiator in our Mitcham house never warmed up. Turned out to be years of scale build-up — flush sorted it and boiler’s much quieter now.
Heating bills had been creeping up in our Raynes Park semi with no obvious cause. Engineer explained the sludge build-up was making the boiler work harder — noticeable difference since the flush.
