Working in Devizes
As well as Devizes itself (SN10), we survey in Calne, Melksham and Chippenham.
Being a smaller town does not change how we work in Devizes: free survey, written quote, one team. If your Devizes en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. For an en-suite in Devizes, the first question at the survey is always where the waste can reach the soil stack.
Most of Wiltshire has hard water. If your supply in Devizes is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
Decisions to make first
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
Rules that apply in England
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
