Ventilation cleaning in Northaw
Need ventilation duct cleaning in Northaw? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.
- Ventilation full of debris from building work
- Supply ducts with years of dust inside
- Ductwork with too few access panels to clean
Between visits
After the visit, a few habits help the work last:
- Log every filter change
- Make sure nothing is stacked against extract grilles
- Store cleaning certificates where auditors can find them
- Include grilles in the cleaning rota
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
Ventilation duct cleaning for kitchens and businesses in Northaw
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. If you are dealing with extract ducts clogged with lint and dust and ductwork that hasn’t been inspected, we can put it right.
Work in a small place like Northaw starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

The process
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes a day or less for a small system and a series of visits for a large one. A quick note on how to find the site and where to park makes a visit to Northaw run smoothly.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Getting ready for the visit
- Mention any parking or loading restrictions
- Let us know about permits to work or site inductions
- Clear loose items from the work area
Ask for a quote
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711 or email us.
Advice
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
What the work involves, part by part
Supply ductwork
Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and we remove it through access panels.
Schools and colleges
We plan the work around the school calendar, with access agreed with the caretaker or site manager.
When something else is needed
In fairness, there are a few things this work won’t fix:
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Damp or mould problems coming from the building fabric
- Building management settings that run the plant
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.

What ventilation duct cleaning looks like in Northaw
Going by the FSA’s register, there are about 8 schools, colleges and universities and about 6 hospitals, care homes and childcare premises serving food across Northaw and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Northaw, about 14 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. Northaw’s nearest hospital, Chase Farm Hospital, is about 3.3 miles south-east.

Common questions in Northaw
Do you work in villages like Northaw?
Yes. Northaw is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Northaw?
Yes, we can come after you close and finish before you open. That way a site in Northaw doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do you inspect before cleaning?
Yes, always. We check the layout, access and condition before giving a fixed quote.
What information do you need?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
How long does ventilation cleaning take?
It takes a weekend for a modest system, with large buildings phased floor by floor. The size of the system and the access make the biggest difference.
What affects the cost of ventilation duct cleaning
You will get a fixed price before we start. It’s based on:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- The scale of the work
- Site rules, permits and inductions
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
Helping us quote
Before you ask for a quote, gather:
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- A few general shots of the system
- The paperwork from the last visit, if you have it
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
