Working in Streatham
As well as Streatham itself (SE27, SW12 and SW16), we survey in Mitcham, Brixton and Wimbledon.
London homes in Streatham often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For an en-suite in Streatham, the first question at the survey is always where the waste can reach the soil stack. We quote new en-suites in Streatham only after checking the drainage route on site, so the price reflects the work your house actually needs.
Water across much of Greater London is very hard. If your supply in Streatham 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 shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
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.
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.
