On this page you will read how to combine those two kinds of work, which brushes and machines fit them and which advice applies to homes and businesses. Lamers Reinigingstechniek from Zelhem supplies the equipment to installers, cleaning contractors and facilities teams.

Dijk en Waard in figures: homes and business parks
Dijk en Waard has 90,076 inhabitants and ranks 42nd of the 342 municipalities. The municipality was formed by a merger and consists of several villages and towns. With urbanisation class 3 it is moderately urban, at a density of 1,455 inhabitants per km². On average 2.37 people live in each household, more than in most large cities: lots of family homes, in other words.
| Sector (CBS 2024) | Establishments | Share | Typical duct work |
|---|---|---|---|
| Business services | 2,515 | 23.3% | office ventilation |
| Industry and energy | 2,095 | 19.4% | workshops, production, source extraction |
| Trade and hospitality | 1,835 | 17.0% | shops, kitchen extraction |
| Government, education and care | 1,760 | 16.3% | schools and care locations |
| Culture, recreation, other services | 1,075 | 9.9% | sport and recreation |
| Transport, information and communication | 740 | 6.8% | warehouses, transport |
Almost one in five establishments works in industry and energy. For an installer that means: alongside home maintenance, there is work on process extraction and workshop ventilation.
Ventilation duct cleaning Dijk en Waard in homes: the advice
If you work for housing associations, owners' associations (VvE) or private clients, use the advice of Milieu Centraal (Dutch public information centre) and the manufacturers as a guideline:
| Component | Advice | Source |
|---|---|---|
| Extract ducts of mechanical ventilation | have them cleaned at least once every 8 years | Milieu Centraal |
| Fan unit | maintenance once every 2 years, check the system roughly every 4 years | Milieu Centraal |
| Ducts of balanced ventilation | roughly once every 8 years | Milieu Centraal |
| MVHR filters | replace at least 2 times a year | Milieu Centraal, Brink |
| Valves of balanced ventilation | every 2 years by a technician | Milieu Centraal |
| Air distribution system | professional cleaning every 8 to 10 years | Zehnder |
For orientation in your quotes: Werkspot mentions €150 to €250 for having ventilation ducts in a home cleaned and €175 to €300 for an MVHR system. More about balanced ventilation is under MVHR duct cleaning.
Duct cleaning Dijk en Waard in the commercial hall
Workshops and production halls follow different rules from homes. Article 4.5 of the Working Conditions Decree (Arbobesluit) requires that when contaminated air is extracted, enough clean air is supplied at the same time. For dust at the workplace, the metal sector uses 10 mg/m³ inhalable and 5 mg/m³ respirable dust as an 8 hour average. The British HSE advises thoroughly examining and testing local exhaust ventilation at least every 14 months.
An extract duct that silts up draws less air away at the source. The result is more dust in the hall. Background for this kind of work is under factory ductwork cleaning.
Which brush do you choose for which duct?
The brush largely determines the result. Danduct Clean supplies shaft brushes in three versions, in diameters from 100 to 600 mm:
| Brush | Use | Home | Commercial hall |
|---|---|---|---|
| Soft | sensitive surfaces, small ducts with bends | ✓ | sometimes |
| Standard (normal) | ordinary dust in sheet steel ducts | ✓ | ✓ |
| Tynex (more aggressive) | caked on dust and deposits | ✗ | ✓ |
The American EPA advises soft brushes for fibreglass duct board and for sheet metal, and advises against simply using biocides or coatings. An explanation of sizes and materials is under duct brush for cleaning contractors.
One kit for homes and businesses: how do you put it together?
An installer who covers both homes and commercial buildings in the towns of Dijk en Waard benefits from a kit that can handle both. A possible set up:
- For short ducts in homes: a machine on a power drill, such as the PD4 with a shaft of 2.5 to 7.5 metres.
- For long commercial ducts: the DC4 with a reach of up to 30 metres, on 230 volts.
- For narrow ducts with many bends: the Intelligent Airnozzle from 30 mm, with camera.
- Always: duct balloons, foam caps for valves and an extraction unit with HEPA.
Not every installer needs everything; start with what you come across most often. A comparison of all machines is on tools for cleaning air ducts explained.
Fictional example: a week in the maintenance schedule
A fictional installer schedules four homes with mechanical ventilation and one workshop with an extract duct of 315 mm over eighteen metres in one week. He does the homes on Monday and Tuesday: valves removed and cleaned, ducts cleaned with a soft brush, fan unit checked. On Wednesday it is the workshop's turn, with a Tynex brush for the deposits and an extraction unit on the duct.
He deliberately works from clean to dirty and does not carry dust or oil from the workshop into a home. The example contains no prices; you request the equipment on quotation from Lamers.
What makes such a week work is preparation. Before Monday he checks which brush diameters each address needs, packs the soft and Tynex brushes separately and cleans shafts and brushes at the end of each day. That way the kit is ready for the next job and nothing from the workshop ends up in a living room.

Frequently asked questions: air duct cleaning Dijk en Waard
How often do you clean mechanical ventilation ducts in a home in Dijk en Waard?
Milieu Centraal advises having the extract ducts of mechanical ventilation cleaned at least once every 8 years. The fan unit needs maintenance once every 2 years and you check the whole system roughly every 4 years. You clean grilles and valves yourself at least once a year.
How many businesses in Dijk en Waard work in industry and energy?
According to CBS 2024 that is 2,095 of the 10,815 establishments, or 19.4%. That is a large share for a moderately urban municipality. That sector runs a lot of process extraction and workshop ventilation, where ducts get dirty faster than in offices or homes.
What does cleaning ventilation ducts in a home in Dijk en Waard cost?
Werkspot mentions €150 to €250 on average for having ventilation ducts cleaned and €175 to €300 for an MVHR system, at an hourly rate of €50 to €75. Homedeal arrives at €100 to €300. The exact price depends on the number of valves and how accessible everything is.
Which brush do you use in Dijk en Waard for a workshop duct with deposits?
For caked on dust and deposits, use the more aggressive Tynex brush from Danduct Clean. A standard brush is enough for ordinary dust, and for sensitive surfaces or small ducts with bends you take a soft brush. All three are available in diameters from 100 to 600 mm.
Can an installer in Dijk en Waard serve homes and businesses with one kit?
Yes, if the kit covers the most common cross sections and lengths. A machine on a power drill for short ducts in homes, the DC4 for long commercial ducts and sealing and extraction materials form a good basis. Lamers advises you on which combination suits your work.
How often do you replace MVHR filters in homes in Dijk en Waard?
Milieu Centraal and Brink advise replacing the filters of an MVHR unit at least 2 times a year, and vacuuming them in between if needed. If the home is next to a busy road, more often. Dirty filters create more resistance; lab research showed that heavily contaminated filters gave 37% less supply air.
Which occupational health rule applies to extraction in a commercial hall in Dijk en Waard?
Article 4.5 of the Working Conditions Decree requires that when contaminated air is extracted, sufficient clean air is supplied at the same time. Article 6.2 requires sufficient uncontaminated air at the workplace. A silted up extract duct can mean you no longer meet those requirements.
May you spray biocides into an air duct in Dijk en Waard after cleaning?
The American EPA reports that no biocides are registered for fibreglass duct board and does not recommend coatings as a routine measure. So choose mechanical cleaning with the right brush and extraction first. If you are in doubt because of mould or moisture, have the cause investigated first.
Does Lamers have a branch in Dijk en Waard?
No, Lamers Reinigingstechniek is based in Zelhem in Gelderland. The family business has been supplying professional cleaning equipment to companies throughout the Netherlands for more than 50 years. For Dijk en Waard you request a quote or ask a question via the site.
Why do you work from clean to dirty in Dijk en Waard?
If you do homes and a workshop on the same day, you would otherwise carry dust, oil or grease from the dirty job to the clean one. So plan homes and offices first and the commercial hall or kitchen extraction last. Clean the brushes and shafts before you move on to the next job.
