Retrofitting fire doors

Compliant in the existing stock — even during live operations. An official requirement, a fire protection report or a defects list after an inspection — we handle the entire process: on-site survey, planning, supply, installation and documentation.

Retrofitting fire doors

When existing-stock protection ends — and retrofitting becomes mandatory.

Existing-stock protection applies as long as a building continues to be used unchanged and no concrete hazard exists. It lapses on a change of use (e.g. office → care facility), on substantial alterations or when the competent authority identifies a concrete hazard. A periodic fire inspection, a fire protection report or an insurance requirement after a claim can also trigger a retrofit duty. The detailed rules are set out in the state building code — in NRW the BauO NRW. A blanket statement is not possible; we refer to the individual fire protection concept and the authority's position. (Note: We do not provide legal advice — in disputed cases please involve a fire protection expert or the authority.)

Why owners and managers retrofit.

Rarely voluntary — usually after one of the following triggers. We know the rules of every authority in North Rhine-Westphalia (NRW).

Fire inspection / fire-prevention inspection

Periodic walk-through by the fire brigade — usually with a defects list and a deadline.

from €1,500

Fire protection report

Expert assessment with concrete retrofit recommendations.

from €2,000

Official use requirement

The building authority demands adaptations — often as part of a change of use.

from €3,500

Insurance requirement

After a claim or at policy renewal the insurer demands evidence.

from €4,500

Change of use

Office → care facility, apartment → practice — new requirements, old doors are not enough.

Substantial alterations

Refurbishment or extension — the existing stock is reassessed.

Where we retrofit most often.

We cover every typical building type — from residential to industrial complexes with hundreds of components per site.

01

Apartment entrance doors

Multi-occupancy residential — usually T30 or T30-RS required. Frequent in refurbishment projects.

02

Basement access & basement doors

Transition from the stairwell to the basement — usually T30-RS.

03

Plant & boiler rooms

Heating, service entry, lifts — separation from rooms with elevated fire load.

04

Corridors & stairwells

Necessary corridors — separation of escape routes.

05

Commercial units

Separation of use units — on re-letting or change of use.

06

Server & plant rooms

Often T90 — at initial fit-out or after IT expansion.

  • Opening

    Existing opening vs. new breakthrough

    We check whether the existing opening fits or a new breakthrough is needed — both are possible.

  • Frame

    Adaptation frames for irregular walls

    Adaptation frames compensate for historical dimensional deviations — approval is still required.

  • Heritage

    Special solutions with timber appearance

    For listed buildings we work with timber decors or real-wood veneer — with full approval.

  • Logistics

    Minimal-impact installation

    Dust protection, partial-section sealing, weekend and night appointments — when operations cannot pause.

  • Combination

    With smoke control or hold-open system

    Often sensible for corridors: T30-RS with hold-open — open in daily use, closed in a fire.

  • Disposal

    Proper disposal of old doors

    We take old doors away, document disposal and engage certified recyclers.
