Ventilation duct cleaning in Farnborough, done properly
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It works by inspecting first and cleaning where the risk calls for it, so we look before we clean. We are often asked to deal with blocked general extract ductwork and stuffy rooms and stale air, on offices and schools, supply ductwork and toilet extract systems.
London buildings tend to keep their plant on the roof or below ground, so work in Farnborough is often done in the evening or at weekends. Loading and parking are planned with the building first.
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’re fully insured.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Keep grilles and diffusers dusted
- Switch the ventilation off or cover grilles during dusty building work
- File each ventilation report with the building records
- Flag any dust coming out of the vents
Share the report with whoever looks after the building’s maintenance, so the history stays together. Year on year, it shows how fast dust builds up.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, clear away 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. In a London area like Farnborough, parking, loading and building access are planned before the day of the work.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
Preparing for the visit
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in

What happens if it’s left?
Clean ducts let the air move as designed, which takes strain off the fans. Leaving them means the plant works harder for the same result. London sites work long hours, and the longer a job is left, the bigger it gets.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711, or send details by email for straight advice and a fixed quote.

What affects the quote in Farnborough
Sites vary more than people expect. What affects the quote:
- A single visit or a regular plan
- Whether several sites go on one quote
- The size of the system
- How easy every part is to reach
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
To help us quote quickly, please include:
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.

How often do ventilation ducts need cleaning?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
Do you survey the system first?
Yes. We always survey first, on site or from photos and drawings, then we give you a fixed quote.
Do we need to close while you work?
Normally not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages so parts stay in use.
What about areas you cannot get to?
We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what ventilation duct cleaning will not do:

If you are not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer.
