How we handle ventilation duct cleaning in Patchetts Green
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. If you are dealing with blocked general extract ductwork and damp or stale smells from grilles, we can help, from offices and schools, grilles and diffusers and supply ductwork onwards.
Work in a small place like Patchetts Green starts with agreeing access and timings.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the quote in Patchetts Green
The quote reflects the site in front of us. We consider:
- Site rules, permits and inductions
- The scale of the work
- Where the site is and how we reach it
- Working hours and out-of-hours timing
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Asking for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

Why it’s worth doing now in Patchetts Green

The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, clear away and leave you the report. On site, the work takes a weekend for a modest system, with large buildings phased floor by floor. A few pictures of the system help us make the most of a visit to a place like Patchetts Green.
- We start by looking at the layout of the ductwork and how it can be reached.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- Dust and debris are removed from ducts, grilles and diffusers.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend

Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Will you look at the ducts before quoting?
Yes. Every job is surveyed first, from photos, drawings or a site visit, and then quote a fixed price.
What does ventilation duct cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Protect the system from construction dust
- Keep filters changed on time
- Report leaks or damp near ceilings and risers
- Diary the next TR19® Air inspection
Keep up with filter changes to protect the ducts. Overdue filters let dust straight back in.
Fit access panels where the ductwork cannot be reached. The worst build-up tends to be where no one can look.

What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

What else we do in Patchetts Green
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Honest limits
Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:
- A system that is not designed to move enough air
- Cooking extract ducts, which are a separate specialist clean
- Controls and BMS faults that affect the system
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.
