Drain Odour Investigation in Walton-On-Thames , Surrey

A sewage smell in the house does not always mean the pipes are blocked. It often points to an "air path" where sewer gases are escaping. This could be a cracked pipe behind a wall, a failed seal on a toilet pan, or a dried-out trap in a shower that hasn't been used for a while. Our Slough drainage specialists use CCTV and smoke testing to find these invisible leaks.

Yes. In older Slough properties with vitrified clay pipes, a fracture can allow foul water to soak into the ground beneath your floorboards. This damp, contaminated soil creates a lingering smell. We can usually identify these cracks with a camera and fix them using trenchless lining, which avoids the need to tear up your flooring.

The Soil Vent Pipe (SVP) is the pipe that usually runs up the side of your house and terminates above the roofline. Its job is to vent sewer gases safely into the atmosphere and equalise pressure in the system. If this pipe is blocked or cracked, gases can build up and push through the water traps in your sinks, or leak directly into your loft and wall cavities.

We use a combination of visual inspections, high-resolution CCTV camera runs, and air pressure testing. By isolating sections of the pipework, we can see where air or water is escaping. This allows us to provide a fixed-price quote for the specific repair needed, rather than guessing at the cause.

While a faint smell is mostly a nuisance, sewer gas contains methane and hydrogen sulphide. In high concentrations within enclosed spaces, these gases can be harmful. It is always best to investigate the source of a persistent smell early to ensure your drainage system is properly sealed and vented.
