Plumbers & electricians in Chatham

The town sits in a valley called The Brook, with the High Street along the bottom of it and the ground climbing away on both sides towards Fort Pitt and Chatham Hill. The Victorian terraces that filled those slopes went up for the dockyard, and because of the gradient the rows follow the contour lines rather than cutting across them, so a street can run almost level while the houses behind it sit a storey higher. Above the yard is Brompton, a village laid out deliberately in the eighteenth century and then boxed in by the barracks and the defensive ditches of the Chatham Lines, which is why Mansion Row, Prospect Row and Garden Street are still Georgian terraces inside a conservation area.

Out to the south east, Luton was a separate village with a pub and a church until the terraced streets running up from the High Street joined it to Chatham for good, under the chalk grassland at Darland Banks.

Then there is the other end of ME4 completely. The dockyard closed in 1984, the land north of the historic yard became Chatham Maritime, and St Mary’s Island was built out from the late nineteen nineties as an estate of around seventeen hundred homes that was only finished in the last few years. Georgian officers' housing, Victorian dockyard rows and houses younger than most of the people living in them, all inside a mile and a half of each other.

Why a drain smell comes and goes in a converted Chatham terrace

---

Every waste fitting has a trap under it, and the trap holds a small plug of water. That plug is the only thing standing between the room and the inside of the drain, and it weighs almost nothing, so it does not take much to move it. What matters in Chatham is how many of the terraces have been split up. Medway Council brought in an Article 4 direction at the end of 2025 covering Chatham Central and Brompton, Fort Pitt and Luton among other wards, because so many houses had been turned into shared homes with nobody needing permission first. Divide a house and the traps in all of it still hang off the one soil stack at the back. So when somebody on the top floor empties a bath or flushes a WC, a slug of water falls down that stack and drags air along with it. Behind the slug the pressure drops, and a trap on a lower floor gets pulled out through its own branch until the seal is gone. Ahead of the slug the pressure rises instead, and a trap can be pushed the other way, which is what the gurgle in an empty bathroom usually is. Either way the branch is now open to the stack, and the room is breathing the same air as the drain until that fitting is next used and the trap fills again.

What the person living there notices is a smell that comes and goes. There in the morning, gone by lunchtime, back at some odd hour, and very often at its worst shortly after a neighbour upstairs has run water.

Because it is intermittent, it gets chased as a blockage, or as something dead under the floor, and it is neither. The fault is in the ventilation, so the work is about letting air into the stack instead of leaving it to steal air out of the traps. That can mean an open vent terminating above the roof where it belongs, or an air admittance valve set high enough above the traps it serves and somewhere it can both draw air and be reached, or a branch put right because it is too long, falls too steeply or turns too many times before it meets the stack. Which of the three it is depends on the building. On a converted terrace there is an honest complication as well, because the cause is frequently not inside your own flat. The discharge that empties your trap happens upstairs, and the vent that ought to be handling it sits on somebody else’s wall or in somebody else’s cupboard, so a fair part of the job turns out to be agreement and access rather than pipework.
