Air duct cleaning in Hilversum

Why Hilversum stands out in the CBS figures

Hilversum ranks 37th of the 342 municipalities in the Netherlands by population, but has more business establishments than many larger municipalities. Its level of urbanisation is very high (class 1), with a density of 2,070 inhabitants per km² on 4,561 hectares of land. Business services alone account for 30.0% of all establishments.

The share of transport, information and communication (11.7%) is higher than in many other medium sized municipalities. Wherever there are server rooms or other technical spaces, the ventilation has to keep running reliably.

Shared systems: who arranges duct cleaning in Hilversum?

In a multi tenant business building, responsibilities overlap. Two sets of rules help to sort them out:

• The Building Works Living Environment Decree (Bbl) (art. 3.67 onwards) requires almost every existing building to have a ventilation provision that prevents damage to health. That concerns the building and therefore the owner.
• Article 6.2 of the Working Conditions Decree (Arbobesluit) requires sufficient uncontaminated air at the workplace and a system that is always in good working order. That concerns every employer in the building; paragraph 6 links the workplace to the requirements of the Bbl.

In practice it works best when the lease or the service charges state who inspects, who cleans and how tenants receive the report. Without that agreement, everyone passes it on and nothing gets done.

A short clause is usually enough: the interval, the responsible party and the format of the report. Put it in writing once and every future maintenance round follows the same pattern.

Ventilation duct cleaning Hilversum: a schedule per floor

Office ducts in shared buildings are often short, with many branches to small rooms. A schedule per floor limits the disruption for tenants:

1. Agree a moment outside office hours with the tenants.
2. Inspect the main run and a few branches on each floor with a camera.
3. Close off the valves with foam caps and put the section under negative pressure.
4. Clean from top to bottom and from main duct to branch.
5. Only replace the filters of the air handling unit after cleaning.
6. Send each tenant a short report with before and after photos.

Compact tools for short office ducts

For a service provider working in many small offices, weight and set up time count. For this purpose Lamers also carries compact duct cleaner. Its specifications were not publicly available when this page was written; Lamers provides them on request. With any compact machine, pay attention to at least the following:

For comparison: the PD4 works with a power drill and shafts of 2.5 to 7.5 metres, the DC4 reaches 30 metres. The full overview is under duct cleaning equipment explained.

For facility service providers: ductwork cleaning Hilversum as an extra service

A municipality with so many small offices is a logical market for installers and cleaning companies adding duct cleaning to their offer. What to watch when you take that step:

• First invest in a kit for the most common cross sections, not in everything at once.
• Make sure you can seal and create negative pressure; without those two you leave dust at the client's premises.
• Work with a fixed report format, so clients can demonstrate their maintenance.
• Know your limits: restaurant kitchens often require a certificate for the insurer.

More on this can be found on the page about become a duct cleaning contractor.

One more tip for a new service line: agree with your first clients that you may use their anonymised before and after photos internally. That builds a library you can use to train colleagues on what clean and dirty look like.

Fictional example: a building with five tenants

A fictional office building in Hilversum has three floors and five tenants. The owner agrees with the tenants that the ducts are inspected once every two years and cleaned where needed, with the costs passed on through the service charges. He chooses that interval based on a trade article on EN 15780, which mentions a risk assessment every 2 years.

At the first inspection, the supply to the ground floor turns out to be the dirtiest, close to the air intake. The installer cleans that floor first on a Saturday and the other two the following weekend. Every tenant receives the same report. Prices for equipment or work are not included in this example; for the machine you request a quote from Lamers.
