FAQs for Chalk
Can you clean school ventilation in Chalk during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chalk. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Chalk outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Chalk needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711 or email us and tell us about the site and its opening hours.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How long will the unit be out of action?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
AHU cleaning in Chalk
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers drain trays, dampers and louvres and heating and cooling coils, and common reasons people get in touch are plant that needs cleaning after a refit and rooms that smell stuffy when the system runs.
In a village or hamlet like Chalk, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Out of sight is the usual reason a rural system goes too long without attention.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

What AHU cleaning can’t fix
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Problems with the unit’s controls or sensors
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Parts of the system we cover
- Internal panels
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Drain trays
Between visits
Once we’ve finished, these simple steps help:
- Report stiff or damaged access doors
- Report water on the plant room floor
- Don’t store bins or materials near the intake
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
AHU cleaning around Chalk
Food Standards Agency records list about 15 schools, colleges and universities registered as food businesses in and around Chalk, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Chalk, about 22 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included. For Chalk, the closest hospital is Gravesham Community Hospital, roughly 2.1 miles north-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Gravesham Community Hospital (about 2.1 miles north-west) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as Thamesview School, ventilation cleaning is best booked for the holidays.

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In a small place like Chalk, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Clear loose items from the work area
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

Multi-site and managed buildings
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
What the work involves, part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
