Why act early in Haslar
Dust streaks around grilles and stale rooms suggest the ducts need looking at. Dealing with them now stops them getting worse. It’s worth booking a check, because nobody sees inside a duct day to day.

Ventilation duct cleaning in Haslar
Ventilation duct cleaning is something we carry out for buildings in Haslar and right across Hampshire, in offices, schools, healthcare buildings and retail. Every job begins with a survey and a fixed quote. The work covers supply ductwork, toilet extract systems and hospitals and care homes, and common reasons people get in touch are ductwork never cleaned since it was installed and odours carried round the building by the ducts.
For a building in or near Haslar, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Different parts, different methods
Schools and colleges
The work is fitted around term dates and events, with access agreed with the caretaker or site manager.
Supply ductwork
Anything in a supply duct can end up in the rooms it feeds. We clean the runs so it isn’t blown back in.
When something else is needed
Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- A system that isn’t designed to move enough air
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Damp or mould problems coming from the building fabric
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.
Where we work
- Offices and schools
- Hospitals and care homes
- Grilles and diffusers
- Supply ductwork
- General extract ductwork
- Toilet extract systems
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep the TR19 certificate and photo report in the maintenance log
- Flag any dust coming out of the vents
- Get leaks near ductwork fixed quickly
- Log every filter change
The report includes a recommended date for the next inspection, based on what we found. Diary it straight away so it doesn’t slip.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
Signs you need ventilation duct cleaning in Haslar
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 these warning signs:
- Ductwork that hasn’t been inspected
- Dust marks around grilles and ceiling diffusers
- Poor airflow from the vents
- Odours carried round the building by the ducts
If you run a surgery, dental practice or care home near Haslar, clean ventilation matters as much to you as to a hospital like Gosport War Memorial Hospital (about 1.2 miles north-west).
Questions to ask before you book
- Proof of insurance
- What records you will receive afterwards
- What hours they’ll be on site
- How areas they can’t reach will be recorded
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a weekend for a modest system, with large buildings phased floor by floor. Pictures of the system and its access let us plan the work in Haslar before we set off.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, call 0345 646 2711 or drop us a line.
Related advice
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Haslar questions
Do you work overnight in Haslar?
Yes, evening, overnight and weekend work is normal for us. That way a site in Haslar does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Will you come out to Haslar?
Yes. Villages and rural sites across the South East are part of our work, Haslar included. Photos of the system and directions to the site help us plan the visit.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711, or email photos.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What does TR19 Air cover?
It’s BESA’s guidance for ventilation hygiene in general supply and extract systems, rather than kitchen extract. It’s risk-based and led by inspection, while TR19® Grease covers kitchen extract systems.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
