Ventilation in Salfords buildings
Going by the FSA’s register, there are about 4 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) serving food within about 1.5 miles of central Salfords. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. For Salfords, the closest hospital is East Surrey Hospital, roughly 1.3 miles north. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Salfords, about 21 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you.
If you manage offices or shops near Salfords station, their ventilation can be inspected and cleaned out of hours. If you manage a school such as Salfords Primary School, ventilation cleaning is best booked for the holidays.

AHU cleaning in Salfords, done properly
Our AHU cleaning covers sites in Salfords and the rest of Surrey, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with drain trays holding standing water and units needing a clean before a new tenant or handover, on supply and extract fans, filter sections and dampers and louvres.
Somewhere as small as Salfords, ducted ventilation is typically 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Planning a trip to Salfords ahead is easier for everyone than a rushed one.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It doesn’t solve:
- Faulty motors, drives or bearings
- A system that’s undersized for the building
- Coils that are corroded or leaking and need replacing

What the work covers
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Heating and cooling coils
- Drain trays
Different parts, different methods
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
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.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How it works
Your staff do not need to do much 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. Somewhere as small as Salfords, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Questions from Salfords
Can the work in Salfords be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Will you come out to Salfords?
Yes, Salfords is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you need AHU cleaning in Salfords?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
Healthcare buildings such as East Surrey Hospital, about 1.3 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Salfords, yours matters too.
