What we’re called out for in Sandon
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Sandon can have well-serviced plant and dirty ductwork at the same time.
Look out for these warning signs:
- Odours carried round the building by the ducts
- Construction dust left in ducts after a refit
- Poor airflow from the vents
- Dusty supply ductwork that hasn’t been cleaned in years
If you manage a school such as Sandon Junior Mixed and Infant School, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Whether a survey comes first
- Proof of insurance
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the work can be done while the site is closed
How we handle ventilation duct cleaning in Sandon
Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. If you’re dealing with odours carried round the building by the ducts and duct runs that can’t be reached for cleaning, we can put it right.
Somewhere as small as Sandon, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Sandon questions
Do you work overnight in Sandon?
Yes, we can come after you close and finish before you open. That way a site in Sandon doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Do you offer ventilation duct cleaning in Sandon?
Yes. We work across London and the South East, and Sandon is part of that. A fixed quote normally follows within one working day of the survey details.
Can you set up regular visits?
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.
What about areas you can’t get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What does TR19 Air cover?
TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. TR19® Air takes an inspection-led, risk-based approach.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do we get a certificate after the clean?
Yes, a TR19® certificate and photos. The report lists what was cleaned, anything not reached and the next inspection date.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
What affects the quote in Sandon
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How big the system is
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- Working hours and out-of-hours timing
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or use the quote form, and we’ll explain what it covers.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Problems your staff have spotted
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
Need a price for ventilation duct cleaning? Please give us a ring on 0345 646 2711 or use the quote form and tell us about the site. We will explain what we’d do and send a fixed quote before anything is booked.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a shift or two for a small system, longer for a whole building. Rural roads and tight entrances are worth telling us about before a visit to Sandon.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- Dust and debris are removed from ducts, grilles and diffusers.
- A certificate and before and after photos follow, with anything not reached recorded.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload
Ask for a quote
For a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Switch the ventilation off or cover grilles during dusty building work
- Book the next inspection on the date the report recommends
- Watch for water stains around grilles
- Stick to the filter change schedule
A TR19® certificate and photo report follow every clean. Keep them in the maintenance log, with the date, location and technician recorded.
Protect the system during building work by switching it off or covering the grilles.
