AHU cleaning in Brockham, done properly
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have units that have only ever had filter changes and dust-coated heating and cooling coils, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Photos of the system and how to reach it help us plan a visit to Brockham.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
How to get a quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
AHU cleaning in Brockham: local notes
There are about 3 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Brockham, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Headley Court is the nearest hospital, about 3.9 miles north of Brockham. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Brockham, about 20 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
School buildings such as North Downs Primary School are usually done in the holidays, so classrooms are not disturbed.
Brockham is about 2 miles east of Dorking, in Surrey. Sites in Brockham get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. We cover 395 places across Surrey, from busy centres to quieter spots. We also work in Guildford, about 13 miles from Brockham.
All of RH3 is within our area for AHU cleaning, from busy streets to back roads. Whether your site is on Holly Close, Nutwood Avenue and Kiln Lane or a nearby road, we can help.

Near you in Brockham
Typical jobs here are in premises near The Ashcombe School, Pippbrook House and Inn on The Green, among other places. The nearest railway station is Betchworth station, roughly 1.1 miles north-east of the centre. Well-known places in the area include Reigate Priory Museum (3.3 miles east) and Headley Court (3.9 miles north). For a walk, there’s Reigate Heath and Box Hill.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

How the job changes from site to site
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Our emergency line runs 24/7, but a planned visit to Brockham is calmer for everyone.
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 will explain each part.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Brockham questions
Do you cover Brockham for AHU cleaning?
Yes, Brockham is covered. Just call us on 0345 646 2711 or drop us a line with a few details of the site.
Do you work in villages like Brockham?
Yes. Villages and rural sites across the South East are part of our work, Brockham included. Photos of the system and directions to the site help us plan the visit.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
Can you clean without disrupting the building?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Between visits
Aftercare is simple, and it helps at the next visit:
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
When to call us in Brockham
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Clients typically contact us after spotting something like this:
- Air handling units due a clean after building work
- Dirty fans and fan housings
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
Hospitals such as Headley Court (about 3.9 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Brockham are no different.
