Marsh Gibbon: your questions answered
Can you work in Marsh Gibbon outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Marsh Gibbon keeps running as normal. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you work in villages like Marsh Gibbon?
Yes. Marsh Gibbon is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
AHU cleaning for kitchens and businesses in Marsh Gibbon
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with intake sections clogged with outdoor debris and dust-coated heating and cooling coils, we can put it right, from supply and extract fans, drain trays and dampers and louvres onwards.
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.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Marsh Gibbon.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
Get a fixed quote
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will usually have a quote within one working day.

What we are called out for in Marsh Gibbon
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that’s where slime and odours start.
Keep an eye out for any of the following:
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
- Dirty fans and fan housings
- Coils clogged with dust and debris
Healthcare buildings such as Bicester Community Hospital, about 4 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Marsh Gibbon, yours matters too.
Questions to ask before you book
- How VAT is shown on the quote
- Whether the figure could change on the day
- Proof of insurance
- If they look at the system before pricing
What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
