Common questions in Wiggonholt
Do you work at weekends in Wiggonholt?
Yes, we can come after you close and finish before you open. That way a site in Wiggonholt does not have to lose a day’s trading. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you offer AHU cleaning in Wiggonholt?
Yes. We work across London and the South East, and Wiggonholt is part of that. A fixed quote normally follows within one working day of the survey details.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711 or drop us a line.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
How long does an AHU clean take?
The work takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, and you can call 0345 646 2711 or use the quote form to plan it.
About our AHU cleaning in Wiggonholt
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have plant that needs cleaning after a refit and air handling units never cleaned inside, we can help.
In a village or hamlet like Wiggonholt, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Wiggonholt, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- You get a TR19® certificate and a photo report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Fixed quotes for AHU cleaning in Wiggonholt
The diagnosis comes before the price. We look at:
- The size of the system
- Any permits to work or inductions
- How many systems or sites are involved
- The condition of the system
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- The site address and the type of premises
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
When to call us in Wiggonholt
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Signs it’s time to call us include:
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
Every job around Wiggonholt ends with a record of what was cleaned and what was found.
Questions to ask before you book
- What hours they’ll be on site
- When the next visit should be, and why
- Whether inaccessible sections are listed on the report
- Whether the whole system is included, or only the parts that are easy to reach
What a clean won’t put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
If you’re not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer before you book.
Parts of the system we cover
- Heating and cooling coils
- Supply and extract fans

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
