Ventilation in Lee Common buildings
We cover Lee Common, about 30 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. The nearest hospital to Lee Common is Chiltern Hospital, about 2.7 miles south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Wherever a school like Lee Common Church of England School has ducted ventilation, a half-term visit keeps the work out of lesson time.

AHU cleaning in Lee Common
Our AHU cleaning covers sites in Lee Common and the rest of Buckinghamshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include odours coming through the supply air and air handling units with blocked filters, across dampers and louvres, supply and extract fans and heating and cooling coils.
Somewhere as small as Lee Common, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Lee Common, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids

What else we do in Lee Common
Common problems we fix in Lee Common
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
What we are most often called out for:
- Dirty filters cutting the airflow
- Rooms that smell stuffy when the system runs
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
Chiltern Hospital, about 2.7 miles south, is the nearest hospital to Lee Common, and healthcare sites of every size need their supply air kept clean.
Before you book anyone
- Whether the figure could change on the day
- How VAT is shown on the quote
- What hours they’ll be on site
- Whether a written report and photos are included
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. It’s simpler to plan the work at Lee Common now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.
Why book with us
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fixed quotes, normally within one working day
- Full insurance on every job
- A single point of contact for sites across the South East and London
Common questions in Lee Common
Do you work overnight in Lee Common?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you work in villages like Lee Common?
Yes, we work in villages as well as towns, and Lee Common is covered. Just mention lanes, gates or anything else about the site when you book.
How long will the unit be out of action?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Is a quote from photos possible?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If photos aren’t enough, we’ll survey first.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Report musty smells from the vents straight away
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Building management system faults
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.
Parts of the system we cover
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- The times the site is available
- How many systems or sites are involved
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711, or send details by email, and we will explain what it covers.
Helping us quote
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
