How an OVK inspection works

We keep the process simple and predictable for property owners and housing association boards, from first contact to approved protocol.

  1. Planning and notification

    You book a time with us, and we prepare and send notices to residents or tenants.

  2. System review

    The inspector goes through the building's drawings, system data and earlier protocols.

  3. Measurement and checks

    Air flows are measured, functions are tested and fans, vents, filters and ducts are inspected.

  4. Hygiene and function assessment

    We make sure the system meets the requirements that applied when the building was constructed.

  5. Protocol

    An OVK protocol is issued, a copy is sent to the municipality and a certificate is displayed in the building.

  6. Remedial action

    If deficiencies are found, we help you with proposed measures within the stated time.

What does an OVK inspection cost?

Every property is different, so we do not have a price list. Instead you receive a fixed price in your quote, adapted to your building. Request a free quote and you will get a reply within 24 hours, or call us directly.

    The number of apartments or premises to be inspected.

Frequently asked questions about OVK

What does an OVK inspection cost?

The price depends on the size of the building, the type of ventilation system and the number of apartments or premises. Every property is different, so we have no price list. Instead you receive a fixed price in your quote.

Request a quote and we will reply within 24 hours.

How often must OVK be carried out?

It depends on the type of building and ventilation system:

  • Preschools, schools and healthcare premises: every 3 years, regardless of system
  • Apartment buildings and offices with FT or FTX ventilation: every 3 years
  • Apartment buildings and offices with S, F or FX ventilation: every 6 years
  • Detached and semi-detached houses: normally only one inspection when the system is taken into use

Not sure what applies to your property? We will help you find out.

Who is responsible for OVK?

The property owner, or the board of the housing cooperative, is always responsible for having OVK carried out within the correct interval.

Who notifies the residents?

Informing residents is the responsibility of the property owner or the housing cooperative board. We always provide ready-made notices and, if agreed in advance, can handle the notification for you.

What happens if the system fails the inspection?

If deficiencies are found, you must correct them within a set time and then have a new inspection carried out. The protocol shows what needs to be fixed, and we help you with proposed measures.

What happens if OVK is not carried out in time?

The municipality can require action and impose a financial penalty if the owner does not fulfil the obligation. A missed inspection can also affect the value and insurance terms of the property.
