Working in Magherafelt
We cover every part of Magherafelt, including BT45 and BT46, and nearby Cookstown (9.4 miles) and Ballymena (15.2 miles).
Being a smaller town does not change how we work in Magherafelt: free survey, written quote, one team. If your Magherafelt bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. We check door thresholds in Magherafelt homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Supplies across most of County Londonderry are soft. 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A floor sensor set between the heating runs and wired back to the thermostat
- 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
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
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.
