Liquid screed in St Thomas solves what sand-and-cement struggles with — SR1 flatness in a single pour, ready for tilers and joiners within days rather than weeks.

The screed arrives ready-mixed on a truck, gets pumped through a hose to wherever it's needed in the building, and self-levels to within a couple of millimetres across the room. We spike-roll it to release air, then leave it.

Most of our St Thomas jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. St Thomas sits Exeter (1 mi), and we work the surrounding villages on the same week's diary.

Built for St Thomas homeowners and contractors alike

St Thomas runs a healthy mix of residential renovation and small-to-medium commercial fit-out. We price both, and run both with the same fixed-price approach.

Liquid Screed in St Thomas — how it works

Liquid screed bonds into a single monolithic layer with no bays, no day joints and no need for steel mesh — it's poured around any UFH pipework you've already pressure-tested.

Unlike a traditional sand-and-cement screed, you'll be back on the floor in 24-48 hours rather than a week, and the surface is flat enough to lay LVT or large-format tile without further latex.

What people in St Thomas usually ask

Do you offer a guarantee?+

Yes — as a Cemfloor-certified installer, qualifying jobs are backed by a 10-year manufacturer-supported guarantee.

Can liquid screed go over an existing concrete slab?+

Yes — typically unbonded over a DPM and slip membrane, from 35mm. We'll assess the substrate at the St Thomas site visit.

How quickly can I walk on a liquid screed floor in St Thomas?+

Light foot traffic from 24-48 hours after the pour. Heavy loading, follow-on trades and final floor coverings depend on depth and ambient conditions — we leave you with clear drying guidance for your specific St Thomas job.

Can you pour in cold weather?+

Yes, with the right ambient control. We won't pour below 5°C and we'll discuss frost protection for any St Thomas pour in the colder months.

Do I need to be on site for the pour in St Thomas?+

Not necessarily — we usually agree access with the main contractor or self-builder and run the pour with our own team. We'll confirm the St Thomas access route, pump position and waste route before the day.

Does liquid screed crack like sand-and-cement?+

Calcium-sulphate and modern cement-based liquid screeds have very low drying shrinkage. With proper edge isolation and joints at doorways, cracking is rare.
