Underfloor heating only works as well as the screed encasing it — and in Exwick that means a high-thermal-conductivity liquid pour that wraps every pipe with no voids.
The screed self-levels around every loop, eliminating the voids you get under hand-laid traditional screed. That means the floor responds faster when the heating calls for it, and stores less wasted heat.
Most of our Exwick jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Exwick sits Exeter (1 mi), and we work the surrounding villages on the same week's diary.

Underfloor Heating Screed in Exwick — how it works
For Exwick UFH builds the typical sequence is: insulation board down, pipes clipped and pressure-tested, edge insulation in place, then we pump and level in a single visit.
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Exwick renovations.
Specifications suited to Exwick builds
Cemfloor Therm
Liquid screed engineered for UFH — lambda 2.1 W/mK, fast response.
PIR/Phenolic insulation board
70-150mm typical depending on build regs U-value target.
Edge insulation strip
Critical around UFH zones to allow thermal expansion.
Pressure-testing kit
Pipes held at 6 bar through the pour to flag any damage immediately.

Why Exwick clients pick us
What people in Exwick usually ask
How does this affect my floor coverings in Exwick?+
Once commissioned and the floor moisture content is signed off (CM test, typically below 0.5% for tile), most coverings go down as normal. We hand you a commissioning record.
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
When can I switch the underfloor heating on in Exwick?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Exwick clients to the schedule.
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
If you're planning Underfloor Heating Screed in Exwick, the brief almost always comes down to flatness, dry-time and access — get those right and the trades behind you stay on programme.
