Ventilation duct cleaning in Anstey, done properly
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. Typical jobs include construction dust left in ducts after a refit and duct runs that can’t be reached for cleaning, on offices and schools, grilles and diffusers and supply ductwork.
Work in a small place like Anstey starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Questions from Anstey
Can you get to a site in Anstey?
Yes, Anstey is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you do school ventilation cleaning in Anstey in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Anstey, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
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. None of it is left on site.
How long does ventilation cleaning take?
Typically, the work takes a weekend for a modest system, with large buildings phased floor by floor. Bigger sites are split into stages, and we’ll confirm the plan when we quote.
What happens if it’s left?
Landlords, tenants and auditors may want proof the ventilation is looked after. A TR19® certificate and photo report from a recent clean give them that. Planning a trip to Anstey ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711, or send details by email for straight advice and a fixed quote.

For landlords and multi-site operators
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 on a regular cycle.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What affects the quote in Anstey
The survey tells us what the work involves. We look at:
- Whether several sites go on one quote
- How easy every part is to reach
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Helping us quote
We can often survey from pictures. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or email photos.
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the TR19 certificate and photo report in the maintenance log
- Make sure nothing is stacked against extract grilles
- Diary the next TR19® Air inspection
- Get leaks near ductwork fixed quickly
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.

What we do, step by step
We start by comparing what we find with the survey or your photos. 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. Rural roads and tight entrances are worth telling us about before a visit to Anstey.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
