Fixed quotes for ductwork cleaning in Harwell
A fixed price needs a few facts first. We look at:
- How easy every part is to reach
- Travel, parking and unloading
- Site rules, permits and inductions
- The number of sites or systems
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Ductwork cleaning in Harwell
We treat ductwork like a doctor treats arteries: find the blockages, clear them, then check the flow is right. Grease readings before and after give you the evidence, alongside before and after photos. If you’re dealing with duct runs with no cleaning record and years of grease along the duct floor, we can help.
Kitchens around a place like Harwell are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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’ll take a look and give you a fixed quote.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a few hours for a short run, longer for long runs and tall risers. Everything the job in Harwell needs is worked out beforehand, from the survey.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think.

Grease, kitchens and Harwell
Food Standards Agency data counts about 17 restaurants, cafés and canteens and about 4 sandwich bars and takeaways in and around Harwell, up to about a mile and a half out. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. In Harwell, food businesses are inspected by environmental health officers from Vale of White Horse council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Harwell is Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run a church or community hall kitchen, near Church of St Matthew or elsewhere in Harwell, its extract still collects grease from every lunch and event. A hospital like Abingdon Community Hospital, about 4.8 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Your questions about ductwork cleaning in Harwell
Can the work in Harwell be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Harwell needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Who enforces fire safety at workplaces in Harwell?
Fire safety enforcement in Harwell is handled by Oxfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
How long will the duct clean take?
Allow a few hours for a short run, longer for long runs and tall risers. The survey tells us how long your duct needs.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Is TR19 a legal requirement?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Part by part
Horizontal duct runs
Grease settles on the floor of a flat duct run. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Vertical risers
Risers often pass through floors and walls, so fire dampers may be fitted where it crosses them. We test those as a separate job.
Common problems we fix in Harwell
Grease in a duct running from a kitchen in Harwell is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Most sites get in touch after spotting one of these:
- Years of grease along the duct floor
- Grease leaking from duct joints
- A duct clean needed for an insurer
- Gaps where access panels were never fitted
For schools such as Harwell Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
What your quote should include
