Ventilation duct cleaning in Graveley
A dusty duct in a building in Graveley is more than an eyesore. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. Typical jobs include poor airflow from the vents and systems with no record of inspection or cleaning, across grilles and diffusers, hospitals and care homes and offices and schools.
For a building in or near Graveley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
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.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Ventilation in Graveley buildings
Food Standards Agency data includes about 8 schools, colleges and universities and about 7 caring premises (care homes, nurseries and hospitals) within about 1.5 miles of central Graveley. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Graveley is Lister Hospital, about 0.8 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Graveley, about 31 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
For schools like Graveley Primary School, the holidays are the usual time to inspect and clean ventilation. Healthcare ventilation, from large hospitals like Lister Hospital (about 0.8 miles south) to small clinics, depends on clean filters, coils and ducts.

What else we do in Graveley
Leave it or put it right?
Leave dust in the ductwork and it keeps building. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. It’s simpler to plan the work at Graveley now than to arrange it in a hurry later.
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’re unsure, ring 0345 646 2711, or email photos for straight advice and a fixed quote.

Different parts, different methods
Hospitals and care homes
Hospitals and care homes are occupied day and night. The work is sequenced with staff to keep disruption down.
Extract ductwork
A dirty extract duct makes its fan work harder. A clean duct takes the load off.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Diary the next TR19® Air inspection
- Report leaks or damp near ceilings and risers
- Don’t run the ventilation while builders are sanding or cutting
- Keep vents and grilles clear of shelving and stock
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Fit access panels where the ductwork can’t be reached. Hidden sections are the ones that get worst.
When it’s something else
We will always give you a straight diagnosis, so here’s what ventilation duct cleaning won’t do:
- Leaking or broken duct sections
- Problems with how the system is controlled
- Condensation caused by the building rather than the ducts
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.

Graveley: your questions answered
Can the work in Graveley be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Graveley keeps running as normal. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Will you come out to Graveley?
Yes, we work in villages as well as towns, and Graveley is covered. Photos of the system and directions to the site help us plan the visit.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do we get a certificate after the clean?
Yes, a TR19® certificate and photos. The report lists what was cleaned, anything not reached and the next inspection date.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What if there aren’t enough access panels?
Nothing is hidden: any section we couldn’t get into is listed. We can install panels to open those sections up.
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, and kitchen extract falls under TR19® Grease.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a weekend for a modest system, with large buildings phased floor by floor, and the area is cleaned down before we leave. Somewhere like Graveley, lanes, gates and parking are worth mentioning in advance.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
