Working in Gravesend
As well as Gravesend itself (DA11 and DA12), we survey in Swanscombe, Grays and Longfield.
Homes in and around Gravesend vary, so we look at the floor, the walls and the water system before we price anything. If you live in a Gravesend flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. If your Gravesend en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Water across much of Kent is very hard. If your supply in Gravesend 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 shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- 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
- 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.
