Ventilation cleaning · home, apartment and HOA
We clean the ventilation in houses and apartments: round and flexible ducts, ceiling grilles, valves and the MVHR unit in the technical room. Here you can read what you can do yourself, what we carry out and how a visit to your home works.
Warning signs
A contaminated system rarely announces itself straight away. It starts with subtle signs you have already seen or heard at home. If you recognise several of them, having the installation assessed is the logical next step.
The extract valves in the bathroom, kitchen or workroom often carry a visible layer of dust. Take the valve off and you see immediately how much has built up.
A valve packed with dust opens and closes sluggishly. You hear that as a squeaking or grinding sound, especially in a quiet room such as the bathroom at night.
In a heavily soiled extract, less air is discharged per hour. You notice it mainly through moisture, odours and the sense that the air in the room never feels truly refreshed.
In an MVHR installation dust and fibres circulate through the system several times before being discharged. The valves in the unit and the filter section therefore load up faster.
Your home
In a home you are usually dealing with a mechanical ventilation system or an MVHR installation. The ducts run through ceilings, service shafts and basements, and those are exactly the places that rarely get maintained.
The heat exchanger of an MVHR installation is not opened; that requires a specialist treatment. We do clean the ducts, the valves and the internally accessible parts of the unit.
Do it yourself or have it done
Part of the maintenance of a ventilation system belongs with the residents. Another part requires duct work, dismantling and technical access. Below we make that division as concrete as we can.
What you do yourself saves us time and keeps the price down. We do assess the filter condition, so you know which filters you need.
We only work on the parts listed in the agreed scope. What is unreachable or cannot be treated safely is named, not quietly skipped.
How it works
We work in four fixed steps. You know in advance what happens, what to expect and what you need to do yourself.
You send photos of the rooms with the grilles, of the technical room and of the MVHR unit. From those we assess the type of system and how accessible it is.
We look at which ducts and valves can be reached, how much contamination is visible and which parts fall outside scope. We explicitly add that last part.
You receive the scope on paper with a fixed price. We only start after your approval. If we encounter extra work along the way, we discuss it with you first.
We clean the agreed components, put the grilles and valves back in place and deliver photos of the work carried out.
In a tenant situation, permission from the landlord or the HOA is required before we start. We cannot arrange that permission for you, but we can assess the installation as soon as you have it.
Limits
A ventilation system in a home is not equally accessible in every home. We say up front what can and cannot be done, instead of explaining it afterwards.
Field view
These photos show the components of a home ventilation system as we encounter them during an assessment. They are not intended as evidence of a specific assignment or location and deliberately do not show a cleaning result.
The photos show what we encounter in a home. They do not show a cleaning result and are not evidence of a completed assignment.
Questions
The questions we are asked most often by homeowners, tenants and individual HOA members.
You do not have to wait until something goes wrong. A visible dust layer on the valves, a grinding sound when opening them, or less extraction in the bathroom and kitchen are reason enough to request an assessment. We then look at the system and the photos you send.
Yes. Based on your photos we fix the scope with a fixed price up front. That price does not change without your approval. If we encounter extra work along the way, we discuss it with you before carrying it out.
For most homes we need access to the technical room and to the rooms with the grilles. The rest of the home does not need to be cleared. For an MVHR installation the technical room is required, because that is where the unit is.
That differs per home. We clean ducts that can be reached through an inspection opening, a technical room or a ceiling. Ducts that can only be reached through a service shaft or a cut opening fall outside scope. We tell you in advance, so there are no surprises.
No. The heat exchanger itself is not opened; that is only possible with a specialist treatment and without damage. We do clean the ducts, the valves and the filter section around the unit.
Yes, and we recommend it. Check the filters in the filter section and replace them according to the manufacturer's schedule. We assess the filter condition and advise which filters you need; we only replace them ourselves if that is explicitly part of the agreed scope.
In a tenant situation you usually depend on permission from the landlord or the HOA. Request that permission first, preferably with the photos and the scope we send you. As soon as you have it, we can carry out the cleaning.
Quote
Send photos of the rooms with the grilles and of the technical room. We assess accessibility and contamination and come back with a concrete scope and a fixed price. Prefer to talk it through first? Feel free to call us and we will look at the situation together.
