Working in Carrickfergus
We cover every part of Carrickfergus, including BT38, and nearby Newtownabbey (5.6 miles) and Bangor (6.7 miles).
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 bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Where a Carrickfergus home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Most of County Antrim is supplied with soft water. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A floor sensor set between the heating runs and wired back to the thermostat
Decisions to make first
Mat or loose cable
Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.
Insulation board thickness
Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.
Rules that apply in Northern Ireland
Northern Ireland has no Part P, but the heating circuit should be designed, tested and certified to BS 7671, with RCD protection. Building control is not usually involved unless drainage or structural work is being done alongside it.
