Working in Paisley
We work right across Paisley — PA1, PA2 and PA3 — and in neighbouring Barrhead and Renfrew.
Paisley has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. For Paisley homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Paisley home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Water across much of Renfrewshire and Inverclyde is 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
- A floor sensor set between the heating runs and wired back to the thermostat
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.
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.
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.
