About our ventilation duct cleaning in Radwell
In a building in Radwell, the people inside spend hours breathing what the ventilation delivers. 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 systems with no record of inspection or cleaning and construction dust left in ducts after a refit, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- Cooking extract ducts, which are a separate specialist clean
- Design problems with the ductwork layout
- Condensation caused by the building rather than the ducts
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before you book.

What affects the cost of ventilation duct cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Site rules, permits and inductions
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- When the site is open and when it’s quiet
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Ventilation in Radwell buildings
There are about 5 schools, colleges and universities and about 12 hospitals, care homes and childcare premises on the FSA’s food hygiene register within 1.5 miles or so of the middle of Radwell. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Fairfield Hospital is the nearest hospital, about 1.9 miles west of Radwell. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. About 35 miles out from central London, Radwell is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Healthcare buildings such as Fairfield Hospital, about 1.9 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Radwell, yours matters too. Wherever a school like Norton St Nicholas CofE (VA) Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Don’t block grilles with furniture or storage
- Log every filter change
- Keep grilles and diffusers dusted
- Switch the ventilation off or cover grilles during dusty building work
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Year on year, it shows how fast dust builds up.
Don’t let construction dust into the ventilation by switching it off or covering the grilles.

What happens if it’s left?
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Acting early keeps the clean simpler. It’s worth booking a check, because nobody sees inside a duct day to day.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

How long does ventilation cleaning take?
As a guide, it takes a weekend for a modest system, with large buildings phased floor by floor. Bigger sites are split into stages, to fit around the building.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. We will ask for anything else we need.
Do you survey the system first?
Yes. TR19® Air is inspection-led, so we look inside the ducts at set points and record what we find. Cleaning is recommended where it’s needed.
Will we have paperwork to show the system was cleaned?
Yes. You get a certificate with the date, location and technician, along with pictures before and after.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Is a quote from photos possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
