Working in Castlereagh
We work right across Castlereagh — BT5, BT6 and BT7 — and in neighbouring Belfast and Newtownabbey.
Homes in and around Castlereagh vary, so we look at the floor, the walls and the water system before we price anything. In Castlereagh flats, the lease and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent. Whether your Castlereagh bathroom needs a refresh or a full strip back to brick, the written quote shows both where both are realistic.
Water across much of County Antrim is soft. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Tiling, fitting of the suite and furniture, making good and decorating, then handover
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Repairs to rotten floorboards, joists or other timber found once the room is open
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
Decisions to make first
Combining rooms
Taking out the wall between a bathroom and a separate WC gives one larger room, but it is structural work and may need building control.
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers drainage, structural changes and ventilation, with ventilation set out in Technical Booklet K. There is no Part P, but new wiring should be designed, tested and certified to BS 7671.
