Water Main Services
Keeping Your Clean Water Flowing
Most of the time, people call us about dirty water (drains). But the pipe that brings fresh, clean drinking water into your home is just as important.
Your Water Main (or supply pipe) runs underground from the street boundary to your internal stopcock. If it leaks, bursts, or gets old, it can cause low pressure, high bills, and damage to your property.
In simple terms: We look after the pipe that brings fresh water into your property—fixing leaks, installing new supplies, and improving pressure.

Why Do Water Mains Fail?
Unlike drains, your water supply pipe is under constant pressure. Over time, things can go wrong due to:
- Age: Many older homes still have lead or iron pipes that corrode or pose health risks.
- Movement: Ground shifting in winter can snap rigid pipes.
- Tree Roots: Putting pressure on the pipe.
- Accidents: Damage caused during building work.
You usually know you have a problem if your water bill spikes, your pressure drops, or you find a soggy patch of grass in the garden that never dries out.

Our Water Main Services
We cover everything from a quick repair to a full new installation. Here is an overview of how we can help:
1. Find & Fix Leak Repair – Stop the Wastage. If you have a leak but don’t know where it is, we use listening devices to find it. Once located, we dig a small, targeted hole to repair the pipe and get your water flowing safely again. If the leak is not audible and there are no obvious signs, we can cut and cap the pipe in various places to locate the leak.
2. Water Main Installations & Re-Routes – Moving Pipes or Installing New Ones. Whether looking to upgrade or replace an existing supply, install a brand new one or re-route pipework around planned building works, we’ve got you covered.
3. Water Main Repairs – Urgent Fixes. If you have a burst pipe or a sudden loss of water, our teams can excavate and repair the damaged section to restore your supply quickly.
4. Moling (Trenchless Installation) – The “No-Dig” Solution. Need a new water pipe but don’t want to dig up your driveway? We use a “Mole”—a pneumatic device that tunnels underground to lay your new pipe without trenching through your garden or paving.
Who Is This For?
- Homeowners: Upgrading old lead pipes to modern plastic (MDPE) for better health and pressure.
- Renovators: Moving pipes to make way for a new kitchen extension.

Testimonials
What Our Clients Say
“I called at 08:10 hours to report a blocked drain. A little while later, Darren rang to tell me he’d arrive in half an hour. He arrived on time and resolved the problem quickly and without fuss. He was polite and friendly throughout. Within two hours of reporting the blockage, all was well. Thank you.” Customer, Surrey
“I unreservedly recommend ASL. All the glowing reviews of ASL are true. They had to lift paving slabs to fix my drains, and I was concerned there might be unavoidable damage. I should not have worried. Liam and Richard did a superb job. Thanks, ASL” Customer, Surrey
“Darren arrived very promptly and got to work quickly. He did an excellent job and explained what he was doing. We would have no hesitation in recommending ASL Services.” Customer, Surrey
“Very efficient to book them to sort out a sewer drain blockage, and the cost was exactly what they quoted. Called before they arrived with a clear ETA. Got on with the job and sorted it out within the hour. Darren was excellent – very courteous and helpful, did more than we expected to help sort the problem out and was a font of knowledge on all things sewer-related. Given the subject matter (eeew) the whole experience with ASL was an absolute pleasure.” Customer, Surrey
“ASL recently carried out a drain repair at our house. They responded quickly to the call for help, came out and soon diagnosed the problem – tree roots blocking the drain. The remedial work on site was carried out by Lester and George – they worked hard and were very thorough. This is a long-established company that seems to know what they are doing.” Customer, Surrey
