How we handle ventilation duct cleaning in Warner's End
When the work is finished, you get a TR19® certificate and before and after photos. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. The work covers offices and schools, hospitals and care homes and toilet extract systems, and common reasons people get in touch are systems with no record of inspection or cleaning and odours carried round the building by the ducts.
Smaller buildings around Warner's End often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Do you need ventilation duct cleaning in Warner's End?
In a building in Warner's End, the ventilation may run for long hours every day, and every hour of running brings more dust with it. Heavier use means faster build-up.
Look out for any of the following:
- Dusty supply ductwork that hasn’t been cleaned in years
- Odours carried round the building by the ducts
- Ductwork that hasn’t been inspected
- Dust marks around grilles and ceiling diffusers
School buildings such as Micklem Primary School are usually done in the holidays, so classrooms are not disturbed.

What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off.

- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.

- Have your last certificate or report to hand

Advice
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Report dust blowing from grilles right away
- Protect the system from construction dust
- Diary the next TR19® Air inspection
- Stick to the filter change schedule
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Regular inspection is the core of TR19® Air. Inspecting on a schedule catches build-up before it becomes a big clean.
What happens if it’s left?
A clean system moves air more easily, which takes strain off the fans. Dirty ducts make the whole system work harder. When a site near Warner's End shuts unexpectedly, the people who rely on it notice at once.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Warner's End questions
Can you come to Warner's End after we close?
Yes. We work evenings, overnight and at weekends. The work in Warner's End can fit around your hours. Your opening times are the first thing we ask for.
Do you cover smaller places like Warner's End?
Yes, we work in villages as well as towns, and Warner's End is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, 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.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do we need to close while you work?
Not normally. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
