Working in Staines
In Staines we cover TW15, TW16, TW17 and 1 more postcode districts; we also cover Egham, 2 miles away, and Ashford.
In Staines, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Staines en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. If your Staines home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.
Most of Surrey has hard water. If your supply in Staines 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
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.
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
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.
