Working in Portishead
As well as Portishead itself (BS20), we survey in Nailsea, Clevedon and Bishopsworth.
Homes in and around Portishead vary, so we look at the floor, the walls and the water system before we price anything. If the en-suite in your Portishead home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If your Portishead en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of Somerset has hard water. If your supply in Portishead 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 survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
Decisions to make first
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.
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.
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.
