Working in Maidenhead
As well as Maidenhead itself (SL6), we survey in Marlow, Slough and Windsor.
Homes in and around Maidenhead vary, so we look at the floor, the walls and the water system before we price anything. If you live in a Maidenhead flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. We quote new en-suites in Maidenhead only after checking the drainage route on site, so the price reflects the work your house actually needs.
Supplies across most of Berkshire are hard. If your supply in Maidenhead 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
- 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
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A door that suits a tight space: inward, outward, sliding or a pocket door
Decisions to make first
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
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.
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.
