Working in Derry
In Derry we cover BT47 and BT48; we also cover Limavady, 14.7 miles away, and Coleraine.
Derry is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Derry home is older and the bathroom still has original pipework or plaster behind the tiles, the survey shows whether a renovation or a refit makes more sense. A renovation survey in Derry looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper.
Supplies across most of County Londonderry are 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
- Repairs to rotten floorboards, joists or other timber found once the room is open
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
Decisions to make first
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Pipe material
Copper suits exposed runs and the area near the boiler. Plastic pipe is quicker under floors and inside walls, and long runs need fewer joints.
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.
