Ventilation duct cleaning in Theydon Bois, done properly
Ductwork is reached through access panels at intervals along the system. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels for the next clean. If you have musty smells from the ventilation and ductwork with too few access panels to clean, we can help, from offices and schools, toilet extract systems and general extract ductwork onwards.
For a building near Theydon Bois, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Multi-site and managed buildings
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.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

Food Standards Agency data includes about 4 schools, colleges and universities and about 4 care, childcare and hospital premises within roughly a mile and a half of the centre of Theydon Bois.

What happens on the day
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes from one overnight visit to a phased programme over several weeks. For a place like Theydon Bois, we load the van from the survey notes so the work can be done in one visit where possible.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Name a contact who can let us in at the agreed time

FAQs for Theydon Bois
Do you clean school ventilation in Theydon Bois in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Theydon Bois, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you get to a site in Theydon Bois?
Yes. Theydon Bois is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How much time does a ventilation clean need?
Work on site takes a weekend for a modest system, with large buildings phased floor by floor. The survey gives us a clearer idea, so call 0345 646 2711 or use the quote form to get started.
How do you deal with ducts you cannot get into?
We clean what we can reach and note the rest. Fitting access panels tends to be the answer, and we can fit them.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Can you clean without closing the building?
Yes. We fit the work around when the building is in use. Holidays suit schools, and evenings or weekends suit offices.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.

Why deal with it now?
Starting with an inspection means you only clean what needs it. Putting the inspection off just means you don’t know where you stand. You choose the date of a planned visit, and a breakdown never asks.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

What a clean will not put right

- Condensation caused by the building rather than the ducts

What affects the quote in Theydon Bois
Before we fix a price, we need to know a few things. We check:
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
For a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Looking after it afterwards
Once we have finished, these simple steps help:
- Diary the next TR19® Air inspection
- Watch for water stains around grilles
- Switch the ventilation off or cover grilles during dusty building work
- Store cleaning certificates where auditors can find them
If there’s building work planned, protect the ventilation. Turn off the system or cover the openings during dusty jobs.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
