- First the system is surveyed, on site or from pictures and drawings.
- Inspection comes next, with pictures of the inside of the ducts.

- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- A certificate and before and after photos follow, with anything not reached recorded.

What affects the cost of ventilation duct cleaning
We don’t publish a price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- The scale of the work
- A single visit or a regular plan
- Site rules, permits and inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Where the site is and what kind of site it is
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, call us on 0345 646 2711, or send details by email.
Do you need ventilation duct cleaning in Lower Assendon?
Damp ducts hold onto dirt. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.
Signs it’s time to call us include:
- Blocked general extract ductwork
- Ventilation that needs a TR19® Air inspection
- Musty smells from the ventilation
- Ducts that need a clean before handover
Classrooms and halls at schools such as Rupert House School are easiest to work in when pupils are away.
Before booking anyone
- What happens if part of the system can’t be accessed
- Proof of accreditation you can verify
- Whether a survey comes first
- Whether a written report and pictures are included
Leave it or put it right?
If a building in Lower Assendon has just been refitted, now is the time to clean the ductwork. Otherwise the dust from the works comes out of the grilles once it’s switched back on. Equipment tucked in a roof space or outbuilding near Lower Assendon rarely gets looked at unless someone books it.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
Why us?
- We’re fully insured
- A single point of contact for sites across the South East and London
- In business since 2009

FAQs for Lower Assendon
Can a school’s ventilation in Lower Assendon be done out of term time?
Yes, and it’s the easiest time to do it. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Lower Assendon. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.

Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What is TR19® Air?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. TR19® Air takes an inspection-led, risk-based approach.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Book the next inspection on the date the report recommends
- Get leaks near ductwork fixed quickly
- Tell your facilities team about dirty diffusers
- Include grilles in the cleaning rota
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Protect the system during building work by switching it off or covering the grilles.
