Ventilation duct cleaning in St Albans, done properly
Ventilation duct cleaning is something we carry out for buildings in St Albans and right across Hertfordshire, from offices and schools to hospitals, care homes and shops. Every job begins with a survey and a fixed quote. Common call-outs are for ductwork never cleaned since it was installed and dust marks around grilles and ceiling diffusers, across grilles and diffusers, hospitals and care homes and general extract ductwork.
Larger buildings in St Albans can have several air handling units serving different floors. Filters, coils, drain trays and fans all need cleaning, and standing water in a drain tray is a common finding.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Common problems we fix in St Albans
Filters never catch everything, and that fine dust settles along the supply ducts. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
Look out for these warning signs:
- Systems missing access panels
- Toilet and washroom extracts full of fluff
- Stuffy rooms and stale air
- Ventilation full of debris from building work
Classrooms and halls at schools such as Loreto College are easiest to work in when pupils are away.
What your quote should include
- If they look at the system before pricing
- Whether the whole system is included, or only the parts that are easy to reach
- What paperwork you get at the end
- How they set the interval to the next visit

Dust in supply ducts can be blown straight into occupied rooms. Cleaning it deals with the source.
What affects the quote in St Albans
The diagnosis comes before the price. The main factors are:
- The number of sites or systems
- The size of the system
- The condition of the system
- Whether we need access equipment or extra panels
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
You don’t need the technical terms. Just send:
- Any access panels or hatches you can see
- A few general shots of the system
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
St Albans: your questions answered
Do you cover St Albans for ventilation duct cleaning?
Yes. Our area runs across London and the South East, St Albans included. A fixed quote typically follows within one working day of the survey details.
Can ventilation in schools around St Albans be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 19 schools, colleges and universities with registered kitchens within about a mile and a half of St Albans. Just give us a ring on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
How do you deal with ducts you can’t get into?
The report shows exactly which parts weren’t reached. Access panels can be added where needed.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
What does TR19 mean?
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 legislation, but it’s the standard people check against.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a day or less for a small system and a series of visits for a large one, and we clear up before we go. Larger sites in St Albans can be done in phases, out of hours, so part of the building keeps working.
- First the system is surveyed, on site or from pictures and drawings.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
How to prepare
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Why it’s worth doing now in St Albans
In healthcare, care and education settings, ventilation cleaning is hard to put off. Good indoor air starts with a clean system. If an insurer or inspector asks when the work was last done, an up-to-date certificate answers the question.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
