Working in Nairn
As well as Nairn itself (IV12), we survey in Forres, Inverness and Elgin.
Being a smaller town does not change how we work in Nairn: free survey, written quote, one team. We check door thresholds in Nairn homes at the survey, because underfloor heating and new tiles raise the floor slightly. For Nairn homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Supplies across most of the Highlands and Islands 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
Decisions to make first
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
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 Scotland
Scotland has no Part P. Underfloor heating added during a straight bathroom refit rarely needs a building warrant on its own, but it must be installed, tested and certified to BS 7671 with RCD protection.
