What happens if it’s left?
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Dealing with them now stops them getting worse. In a small place like Northbrook, a system that fails can take a site out of use.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

Ventilation duct cleaning in Northbrook
Inspection comes first. We look inside the ductwork at set points and record what’s there, then recommend cleaning where it’s needed. That way the work matches the real condition. Common call-outs are for construction dust left in ducts after a refit and damp or stale smells from grilles, on toilet extract systems, grilles and diffusers and offices and schools.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Fixed quotes for ventilation duct cleaning in Northbrook
The diagnosis comes before the price. The main factors are:
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
- What state the system is in
- Site rules, permits and inductions
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711, or email photos.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a shift or two for a small system, longer for a whole building. Rural roads and tight entrances are worth telling us about before a visit to Northbrook.
- We start by looking at the layout of the ductwork and how it can be reached.
- We inspect inside the ductwork at set points and photograph it.
- We protect the rooms beneath and switch the system off.
- Dust and debris are removed from ducts, grilles and diffusers.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Before we arrive
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Watch for water stains around grilles
- Log every filter change
- Keep to the inspection interval in your report
- Do not run the ventilation while builders are sanding or cutting
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Do not let construction dust into the ventilation by switching it off or covering the grilles.
