Working in Castlereagh
We cover every part of Castlereagh, including BT5, BT6 and BT7, and nearby Belfast (2.3 miles) and Newtownabbey (6 miles).
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Castlereagh en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. For an en-suite in Castlereagh, the first question at the survey is always where the waste can reach the soil stack.
Most of County Antrim is supplied with soft water. If that holds for your street in Castlereagh, 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- 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
Decisions to make first
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.
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 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.
