Common questions in Pleshey
Do you cover Pleshey for AHU cleaning?
Yes. Our area runs across London and the South East, Pleshey included. To start, phone us on 0345 646 2711 or email us with a few photos of the system.
Do you cover smaller places like Pleshey?
Yes, we work in villages as well as towns, and Pleshey is covered. The journey is planned ahead, so a few details about the route help.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
How long does it take to clean an air handling unit?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so give us a ring on 0345 646 2711 or use the quote form to talk it through.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
How we handle AHU cleaning in Pleshey
If the units serving a building in Pleshey have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have plant that has been serviced but not cleaned and debris and leaves in the fresh air intake, we can put it right.
For a building in or near Pleshey, access is agreed in advance and the visit is planned around the journey.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What affects the cost of AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- One-off work versus a regular cycle
- Parking and loading at the site
- Whether we need access equipment or extra panels
- The times the site is available
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 we start.
Asking for a quote
When you call or email, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
When to call us in Pleshey
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Common reasons sites call us include:
- Air handling units never cleaned inside
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
An inspection comes first for any ventilation job around Pleshey, so the cleaning matches what’s there.
Questions to ask before you book
- Whether VAT is included
- When the next visit should be, and why
- Exactly which parts of the system are covered
- How areas they cannot reach will be recorded

Honest limits
In fairness, some problems need a different fix:
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer before booking.

Managing agents and facilities teams in Pleshey
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Pleshey are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area 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.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
