Frequently asked questions

Atelier Boonen takes care of the delivery, installation and anchoring of safes entirely in-house. We never use external transporters or installers. Using specialised transport equipment, we deliver discreetly and safely, including to upper floors or hard-to-reach locations. Safes are always wrapped in opaque film and transported in unmarked vehicles to avoid curious eyes.

For safes up to 1000 kg, anchoring is mandatory under the European standard EN 1143-1. We carry out this anchoring carefully, using chemical anchors or adapted solutions depending on the substrate. Where necessary, we use stair climbers and protective materials to safeguard floors, walls and staircases.

The installation is always carried out safely, efficiently and with respect for the building. This guarantees you a professionally executed installation offering the strongest and most durable solution. In 95% of cases, delivery, installation and anchoring are included in the price — at no extra charge.

Read more about our approach: delivery and installation of safes

Yes. As standard, our safes are prepared for anchoring through holes in the base and — depending on the model — in the back wall. If this does not suit your situation, for example with underfloor heating, a wooden floor or a specific setup, we can provide additional anchoring points where needed. Simply mention this when placing your order: the adaptation is carried out at the factory or in our own workshop, without compromising the safe's certification. We then take care of the delivery, installation and anchoring ourselves.
