About our ventilation duct cleaning in Cosham
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, alongside filter changes and AHU maintenance. If you have poor airflow from the vents and construction dust left in ducts after a refit, we can help, from grilles and diffusers, supply ductwork and offices and schools onwards.
Around a place like Cosham, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
The paperwork matters as much as the work. You get a written report with pictures after each 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.

How it works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. For a place like Cosham, we load the van from the survey notes so the work can be done in one visit where possible.
- We survey the system from drawings, photos or a site visit.
- Inspection comes next, with pictures of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- Dust and debris are removed from ducts, grilles and diffusers.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Getting ready for the visit

Ask for a quote
For a fixed quote, phone us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Advice
Common problems we fix in Cosham
Most ductwork is out of sight, so nobody sees the build-up. The grilles get a wipe, but what’s behind them doesn’t.
Look out for any of the following:
- Musty smells from the ventilation
- Dust marks around grilles and ceiling diffusers
- Extract ducts clogged with lint and dust
- Ductwork never cleaned since it was installed
Classrooms and halls at schools such as Court Lane Junior Academy are easiest to work in when pupils are away.
Questions to ask before you book
- Whether the quote shows VAT
- Proof of insurance
- What records you will receive afterwards
- Whether the price is fixed

Where a building in Cosham serves patients, residents or children, putting off ventilation cleaning is hard to justify. Clean ducts are part of providing good air for the people inside. A planned visit to Cosham fits your hours; an emergency does not.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.

Cosham questions
Do you cover smaller places like Cosham?
Yes, we work in villages as well as towns, and Cosham is covered. The journey is planned ahead, so a few details about the route help.
Can you come to Cosham after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Cosham keeps running as normal. Let us know the hours you are closed and we will book within them.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Is TR19 a legal requirement?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Will we have to shut during the visit?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
How much time does a ventilation clean need?
Expect it to take a day or less for a small system and a series of visits for a large one. How much ductwork there is and how easily it’s reached decide the rest.

What else we do in Cosham
Managing agents and facilities teams in Cosham
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
What staff can safely do
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
When it’s something else
A few issues sit outside what this work can do:
- Leaking or broken duct sections
- Cooking extract ducts, which are a separate specialist clean
- Design problems with the ductwork layout
