In the Marais, a flat’s front door is part of the building’s heritage: mouldings, original paint, old ironmongery. We reinforce these doors without changing how they look, or fit security doors that reproduce their design. Measurements taken at your home, free quote.

The Marais is covered by a conservation plan that protects its façades and, in some buildings, its remarkable interiors. On the landing side, the co-owners often insist that all the doors match.
Before any installation, we check with you what the building’s co-ownership rules say and, for a listed building, whether permission is needed. Reinforcement leaves the original door in place; a new door can be given a moulded panel and the same colour as the other doors on the staircase.

From the Carreau du Temple to the Archives nationales, the age of the buildings changes, and with it the type of door.
Grand 17th-century mansions divided into flats: tall doors, often double-leaf, which steel-sleeve reinforcement protects without replacing them.
Old buildings with shops on the ground floor: moulded wooden front doors, to be reinforced or replaced by a door of the same design.
19th-century buildings with simpler entrances: a standard BP1 security door, faced with a moulded panel, fits in well.
Workshops, small flats, buildings put up to be let: depending on the state of the door, reinforcement or a new door, and in both cases an A2P-certified multipoint lock.
A photo of your door and of your neighbour’s across the landing helps us suggest a model that suits the staircase.
For a flat’s front door, it is mainly the building’s co-ownership rules that count: they can impose the colour or design on the landing side. In buildings with protected interiors, other rules may also apply, and the building manager (syndic) can tell you more. We give you the model’s technical data sheet to make approval easier.
No: it is fixed on the inside, to the door and the frame, without touching the mouldings on the landing side. The door becomes heavier, which is why its hinges are reinforced.
Reinforcement starts at €2,690 incl. VAT, multipoint lock included. For a double door, steel-sleeve reinforcement is priced on quotation, after a free measuring visit.
Yes: the manufacturer offers moulded panels, and a made-to-measure panel can reproduce the design of an existing door. On the flat side, you can choose a different finish if you wish.
