80% of Paris break-ins go through the front door. If yours is a classic wooden apartment door, you have two upgrade paths: reinforce it, or replace it entirely with a certified armoured block. Here's how to choose.
Your existing door stays. We dress it with a steel sheet on the inside face, reinforce the hinge side with anti-pinch pins, fit a steel strike frame, and install a high-security 3- or 5-point lock. From about €990 installed.

Door and frame are replaced together by a factory-built steel block, certified A2P BP1 to BP3, fitted to measure. From about €1,890. You gain certified burglary resistance, plus serious sound and thermal insulation — noticeable in a Paris building.
In a French co-owned building, the landing side of your door is part of the building's “harmonie”. Reinforcement rarely raises questions since the outside doesn't change. For an armoured block, the outer finish simply needs to match the existing doors — we photograph the landing, match the style, and prepare the courtesy notice for the syndic when needed.

We do a free on-site assessment: door, frame, floor, building rules, insurance policy. You get both quotes and an honest recommendation — sometimes the answer is simply a better lock, and we'll tell you so.
One call in English — a fixed price — a technician at your door in ~30 minutes.
