Owning an older property in London comes with plenty of charm — period features, solid construction, and a real sense of character. But beneath those floors and gardens, many homes still rely on outdated water supply pipes that can cause leaks, poor pressure, and even contamination.
At Cascade Water Services Ltd, we specialise in lead pipe replacement in London, as well as leak repairs, new water connections, and full supply pipe installations. Here’s a look at the most common water issues we find in older properties — and how we can fix them for good.
💧 1. Lead Supply Pipes
Many London homes built before the 1970s still have lead water supply pipes. Lead can contaminate your drinking water and is no longer considered safe. Even if only part of the supply line is lead, it can still pose a risk.
The fix:
Replacing your old lead supply pipe with modern MDPE (medium-density polyethylene) pipework is the safest, most effective solution. Our lead pipe replacement service in London includes everything — from excavation to reinstatement — ensuring your property is upgraded to a clean, safe, and modern water supply.
⚙️ 2. Corroded or Rusted Metal Pipes
Older iron or steel supply pipes often corrode internally over time, restricting flow and causing discoloured water. You may notice rust-coloured stains or metallic-tasting water.
The fix:
A full or partial replacement using durable, corrosion-resistant MDPE piping restores your supply and ensures long-term reliability.
🚿 3. Low Water Pressure
Low water pressure is one of the most common complaints in older London homes. Narrow, outdated supply pipes, mineral buildup, or hidden restrictions can dramatically reduce flow to taps and appliances.
The fix:
We carry out pressure and flow testing to pinpoint the issue. In many cases, replacing the external supply pipe immediately improves flow and pressure throughout the property.
💦 4. Hidden Leaks Under Driveways or Gardens
In older homes, the water supply pipe often runs under driveways, gardens, or patios. Over time, cracks or splits can develop, leading to hidden leaks, waterlogged ground, or higher bills.
The fix:
Using modern leak detection equipment, we can locate and repair or replace the damaged pipe quickly and efficiently. Our excavation and reinstatement are done neatly, ensuring your property is left tidy and safe.
🏠 5. Shared or Joint Water Supplies
Many London terraces and semi-detached homes still share a water supply with neighbouring properties. Shared connections often lead to poor water pressure and can cause disputes if one property develops a leak.
The fix:
We can install a new, independent water supply connection directly from the mains, giving you full control of your water supply and improving both reliability and pressure.
