Working in Carrickfergus
We work right across Carrickfergus — BT38 — and in neighbouring Newtownabbey and Bangor.
Homes in and around Carrickfergus vary, so we look at the floor, the walls and the water system before we price anything. If your Carrickfergus house has a combi boiler, a loft shower can usually run on mains pressure without a pump. We plan loft bathrooms in Carrickfergus around the roof line, so the shower sits where you can stand and the eaves become storage.
Supplies across most of County Antrim are soft. If that holds for your street in Carrickfergus, 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A check of the floor joists where a bath or large shower tray will sit
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
Decisions to make first
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Getting the water pressure
A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers the new drainage, any structural work to the floor and the ventilation, which is set out in Technical Booklet K. Wiring should be designed, tested and certified to BS 7671.
