Working in Ballymena
In Ballymena we cover BT42, BT43 and BT44; we also cover Antrim, 10.4 miles away, and Magherafelt.
Homes in and around Ballymena vary, so we look at the floor, the walls and the water system before we price anything. If the en-suite in your Ballymena home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If your Ballymena en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of County Antrim is supplied with soft water. If that holds for your street in Ballymena, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- 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
Decisions to make first
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
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 Northern Ireland
In Northern Ireland, building control covers the new drainage and ventilation for an en-suite, with ventilation set out in Technical Booklet K. There is no Part P, but the wiring should still be designed, tested and certified to BS 7671.
