Fire protection provisions are not a one-time investment: due to aging, renovations, or new penetrations, fire resistance can diminish over time. Regular maintenance is essential to safeguard protection in the long term.
Our VCA-certified specialists periodically inspect your fire-resistant seals and penetrations, fire doors, fire dampers and steel protection, repair or replace worn parts, and record every finding.
That recording is what matters at an inspection. We provide and maintain a digital logbook for your building: per provision you can see what was carried out, when, with which material and by whom. For fire-resistant penetrations such a logbook is unavoidable in practice - without a record per penetration you cannot demonstrate that the compartmentation is sound, even if the work was done well.
What you can expect
- Periodic inspection of seals, penetrations, doors, dampers and steel protection
- Digital logbook for your building, kept and updated by us
- Records per penetration and per element, demonstrable at inspection
- Repair or replacement of outdated or damaged components
- Flexible maintenance contracts tailored to your building or portfolio
Applications
Standards & certification
- Manufacturer specifications for periodic maintenance
- NEN 6068 / NEN 6069 as the assessment framework for re-inspection
Our team works VCA-certified and our organization is ISO 9001 and Kiwa (K21050) certified.
More about our certificationsWhat does maintenance & inspection cost?
A maintenance contract is priced based on the number and type of provisions, the inspection frequency, and the size of the building or portfolio. You pay a fixed annual amount for the inspection rounds and logbook management; repair work is quoted separately and in advance. Multiple buildings in one contract reduce the price per property.
Common mistakes
- Only inspecting when there is a check or incident, instead of periodically.
- Inspecting but not reserving a repair budget, so that defects remain unaddressed.
- Not updating the logbook after renovations, so the picture becomes outdated.

Questions about maintenance & inspection
The Bbl does not prescribe a logbook format. The duties of care do apply, such as Article 6.4 for fire-safe use: the Informatiepunt Leefomgeving cites inadequate checks after penetrations are added or changed as an example of conduct contrary to it. Without a record per penetration it is hard to show the municipality, fire service or insurer what was done and when. Some insurers also ask for it.
Per provision: the location, the system or material applied, the installation date, the party that carried out the work and the outcome of every later inspection. For penetrations that is per opening, for doors and dampers per element. We keep the logbook up to date for you, so it stays current and you can show it straight away at an inspection.
We tailor that to the use, the number of changes and the manufacturer's instructions. In buildings with many changes an annual round is common; where little changes, a round every two years can be enough. Fire dampers and fire doors follow the manufacturer's instructions. After a renovation an extra round is sensible, because that is exactly when new penetrations are made.
Yes. We then start with a survey: all provisions mapped, assessing what still complies, repairing what is needed, and building up and maintaining the logbook from that point onwards.
Yes, every inspection produces a report with findings, work carried out and any recommendations.
