Working in Thornaby-on-Tees
We work right across Thornaby-on-Tees — TS16, TS17 and TS18 — and in neighbouring Stockton-on-Tees and Yarm.
Being a smaller town does not change how we work in Thornaby-on-Tees: free survey, written quote, one team. We check door thresholds in Thornaby-on-Tees homes at the survey, because underfloor heating and new tiles raise the floor slightly. For Thornaby-on-Tees homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of County Durham is moderately hard. Mid-tone grout and matt tiles hide the odd water mark better than dark grout and high gloss. 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
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.
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.
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.
