Drain Descaling & Fat, Oil, Grease Removal London

Professional Pipe Descaling & Grease Removal in London & Hertfordshire

Go beyond simple unblocking with our professional drain descaling and fat, oil, and grease (FOG) removal services. Over time, pipes become internally constricted by hard scale and solidified grease, reducing flow and causing constant blockages. We use powerful, specialist equipment to scour your pipework clean, restoring it to its original diameter for homes and businesses across London and Hertfordshire.

Your Local 24/7 Engineers in London & Hertfordshire

For a long-term solution to recurring drain problems, trust our local experts. We have dedicated engineers serving: All London Boroughs (including North, South, East & West London) and Hertfordshire (including Watford, St Albans, Hemel Hempstead, Stevenage, and surrounding areas).

The Cause: the Slow Build-Up Clogging Your Drains

Think of your drainpipes like arteries; over time, their internal diameter can shrink, leading to serious problems. Two main culprits are responsible:

The Problem with Fat, Oil & Grease (FOG)

When hot liquid fats, oils, and grease are washed down the sink, they cool and solidify on the pipe walls. Food particles stick to this greasy layer, which gradually builds up, restricting flow and eventually causing foul-smelling blockages known as "fatbergs."

The Problem with Limescale & Uric Scale

In hard water areas like London and Hertfordshire, limescale deposits slowly coat the inside of pipes, creating a rough, hard surface that snags waste. In soil pipes from toilets, uric scale creates a similar concrete-like build-up. This reduces the pipe's diameter, making blockages much more frequent.

Frequently Asked Questions

Unblocking simply pokes a hole through a blockage to get water flowing again. Descaling and grease removal is a comprehensive clean that scours the entire internal surface of the pipe to remove the build-up that causes the blockages.

We strongly advise against it. Chemical cleaners are highly corrosive and can damage your pipes and the environment. They are also largely ineffective against the hard, built-up layers of grease and scale.

This depends on the volume of business, but we typically recommend a preventative FOG removal service every 6 to 12 months for commercial kitchens to avoid emergency closures.

Our engineers are fully trained to assess the condition of your pipework and regulate the pressure to ensure a safe and effective clean without causing any damage. For very old or fragile pipes, we may recommend electro-mechanical cleaning instead.

Yes, absolutely. We provide descaling and grease removal for all types of properties. It's particularly effective for homes in hard water areas or for resolving persistent kitchen drain problems.
