Working in Melksham
We cover every part of Melksham, including SN12, and nearby Trowbridge (4.8 miles) and Chippenham (6.1 miles).
Being a smaller town does not change how we work in Melksham: free survey, written quote, one team. If your Melksham en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. If you live in a Melksham flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Most of Wiltshire has hard water. If your supply in Melksham 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- 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
Decisions to make first
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
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.
