Antibes building stock: why one method never fits all
In Vieil Antibes and the streets around the Cours Masséna, houses often sit on shallow stone foundations with ceiling heights already reduced by centuries of floor build-ups. Raising the slab by even four centimetres for a traditional wet screed can mean losing headroom on a staircase or bumping into a listed cornice, so low-profile hydronic panels or dry electric mats under new tomettes are usually the realistic option, not the default heavy screed.
On Cap d'Antibes and around Fontonne, villas built from the 1990s onward tend to have generous slab depths and are already plumbed for a heat pump or reversible air-conditioning, which makes full hydronic underfloor heating a natural upgrade — especially for owners who want silent, even warmth under travertine or large-format porcelain around a pool house.
Marina Baie des Anges and the newer résidences along Boulevard du Littoral present a different puzzle entirely: concrete raft slabs, shared risers, and a syndic that must approve any core-drilling or manifold placement in communal areas. We factor those approval timelines into the schedule from the first site visit rather than discovering them halfway through the job.
Choosing between water-based and electric systems on the coast
Salt-laden air and the humidity that rolls in off the Baie des Anges affect drying times for screeds far more than inland Provence — a standard wet screed that cures in three weeks near Grasse can need closer to five in a ground-floor Antibes apartment near the port during a humid mistral-free spell. We plan installation windows around this rather than promising generic drying schedules.
For second homes in Juan-les-Pins that sit empty for much of the winter and are only heavily used from June to September, a responsive electric underfloor system is often more practical than hydronic, since it can be switched on remotely a day before arrival without waiting on a slow-reacting water loop.
Where a property already has a heat pump, as is increasingly common in the villas above Antibes Les Pins and around Juan Pins golf course, a low-temperature hydronic underfloor circuit pairs efficiently with it and noticeably lowers running costs compared with radiators, particularly under the tiled floors that dominate local new-builds.
What an installation in Antibes actually involves
We start with a floor-by-floor survey: current slab height, existing floor covering (tomettes, cement tiles, or the large porcelain slabs common in newer builds), insulation beneath, and access constraints — this matters a great deal in the pedestrian lanes of the old town where materials sometimes have to be hand-carried in rather than delivered by lorry.
For listed or ABF-protected façades near the Château Grimaldi and the ramparts, any work that touches original flooring can require a simple declaration before the tomettes are lifted and relaid, and we handle that paperwork as part of the quote rather than as an afterthought.
On completion we commission the system gradually, raising the floor temperature in small increments over several days — a step that protects both new screed and older encaustic tiling from thermal shock, which is a real risk in properties that have sat unheated through a damp Riviera winter.
Frequently asked questions
Yes, in most cases the tomettes can be carefully lifted, numbered and relaid once a low-profile heating layer is installed beneath them, which preserves the original floor while adding modern heating — we have done this on several properties near the Cours Masséna.
