About our ventilation duct cleaning in Ley Green
Inspection comes first. The ducts are opened at access points and the condition recorded, then recommend cleaning where it’s needed. That keeps the work in proportion to the risk. We’re often asked to deal with ductwork that hasn’t been inspected and damp or stale smells from grilles, across toilet extract systems, grilles and diffusers and general extract ductwork.
For a building in or near Ley Green, access is agreed in advance and the visit is planned around the journey.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What affects the quote in Ley Green
Some jobs are bigger than they look, and some smaller. The main factors:
- The scale of the work
- Where the site is and how we reach it
- Whether several sites go on one quote
- One-off work versus a regular cycle
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
To help us quote quickly, send us:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then call us on 0345 646 2711, or send details by email.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the TR19 certificate and photo report in the maintenance log
- Flag any dust coming out of the vents
- Protect the system from construction dust
- Diary the next TR19® Air inspection
The report includes a recommended date for the next inspection, based on what we found. Diary it right away so it doesn’t slip.
Fit access panels where the ductwork cannot be reached. Hidden sections are the ones that get worst.

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
When to call us in Ley Green
Ductwork is hidden above ceilings and in risers, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
Any of these means the system needs a check-up:
- Ventilation that needs a TR19® Air inspection
- Musty smells from the ventilation
- Poor airflow from the vents
- Ductwork with too few access panels to clean
Lister Hospital, about 4.5 miles east, is the nearest hospital to Ley Green, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- What happens if part of the system cannot be accessed
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
- Whether the quote is based on a survey or pictures
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from one overnight visit to a phased programme over several weeks. Somewhere like Ley Green, lanes, gates and parking are worth mentioning in advance.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
Before we arrive
- Let us know about parking and loading
- Clear the space around the work
- Name a contact who can let us in at the agreed time
Ask for a quote
Getting a quote doesn’t take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Schools and colleges
We plan the work around the school calendar and agree access with the site team.
Supply ductwork
Dust in supply ducts can be blown straight into occupied rooms. Cleaning it deals with the source.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
