Working in Deal
We work right across Deal — CT14 — and in neighbouring Dover and Ramsgate.
Homes in and around Deal vary, so we look at the floor, the walls and the water system before we price anything. We check door thresholds in Deal homes at the survey, because underfloor heating and new tiles raise the floor slightly. Whether your Deal bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Most of Kent has very hard water. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
Decisions to make first
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
Rules that apply in England
In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.
