When to call us in Leamouth
Whatever surrounds a building in Leamouth, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Common reasons sites call us include:
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Dirty coils holding back the airflow
- Dust built up on fan impellers
For schools like St Luke's Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before booking
- When the next visit should be, and why
- If they look at the system before pricing
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Proof of insurance
AHU cleaning in Leamouth, done properly
If the units serving a building in Leamouth have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers internal panels, supply and extract fans and filter sections, and people most often call us about plant that needs cleaning after a refit and dust-coated heating and cooling coils.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Leamouth, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
A written report with photos follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Questions from Leamouth
How do you handle parking and loading in Leamouth?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Do you clean school ventilation in Leamouth in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 53 schools, colleges and universities with registered kitchens within about a mile and a half of Leamouth. Booking early in the term gives the best choice of holiday dates.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Leamouth buildings and their air
There are about 53 schools, colleges and universities, about 53 hospitals, care homes and childcare premises and about 14 hotels and guest houses on the FSA’s food hygiene register in Leamouth and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Ventilation cleaning in London buildings is typically planned for evenings or weekends. Leamouth’s nearest hospital, Poplar Hospital, is about 0.6 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Poplar Hospital (about 0.6 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Leamouth are no different. If you run an office near Custom House station, its supply ductwork can gather dust for years before anyone looks inside.

What happens if it’s left?

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Book the next check in line with the report
- Check the drain tray is emptying during routine visits
- Don’t store bins or materials near the intake
- Report water on the plant room floor
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Honest limits
Before you book, it helps to know what’s not included:
- Airflow problems caused by the system’s design

- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
Fixed quotes for AHU cleaning in Leamouth
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The times the site is available
- How many systems or sites are involved
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
To help us quote quickly, please include:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Photos showing the whole system and its surroundings
For AHU cleaning in Leamouth, call 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. We normally send a fixed quote within one working day.
What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Before any visit in Leamouth, we agree where the van can stop and how equipment reaches the system.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
