What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system

AHU cleaning in Chigwell Row
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you have stale or musty smells from the ventilation and leaves and litter drawn into the unit, we can put it right.
Somewhere as small as Chigwell Row, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Ventilation in Chigwell Row buildings
The FSA’s food hygiene register lists about 6 schools, colleges and universities and about 12 hospitals, care homes and childcare premises with registered kitchens or food service across Chigwell Row and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The nearest hospital to Chigwell Row is Claybury Hospital, about 2.3 miles south-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 12 miles out from central London, Chigwell Row is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
If you manage a school such as Chigwell Row Infant School, ventilation cleaning is best booked for the holidays.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Chigwell Row run smoothly.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Find the previous report, if there is one

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.

Chigwell Row questions
Can you work in Chigwell Row outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in Chigwell Row doesn’t have to lose a day’s trading. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Can ventilation in schools around Chigwell Row be cleaned out of term?
Yes, and it’s the easiest time to do it. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chigwell Row. Booking early in the term gives the best choice of holiday dates.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you cover Chigwell Row?
Yes. Chigwell Row is part of the area we cover, as part of our area across London and the South East.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Leave it or put it right?
If people in a building in Chigwell Row complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A planned visit to Chigwell Row is easier to arrange than an emergency callout.

When to call us in Chigwell Row
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Chigwell Row, that’s air they breathe for hours at a time.
Signs it’s time to call us include:
- Filters that are clogged or overdue
- Condensate trays that won’t empty
- Plant that needs cleaning after a refit
- Dirty fans and fan housings
Hospitals such as Claybury Hospital (about 2.3 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Chigwell Row are no different.
What to look for in a quote
- Whether the quote is based on a survey or photos
- How areas they can’t reach will be recorded
- When the next visit should be, and why
- When they can work, and whether that’s outside your opening hours
Between visits
After the visit, a few habits help the work last:
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
