Ventilation duct cleaning in Coleman Green
Every ventilation system has ducts bringing air in and ducts taking it out. Over time, both collect dust and debris, and some of it is blown back into the building. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. If you have poor airflow from the vents and odours carried round the building by the ducts, we can put it right.
Somewhere as small as Coleman Green, ducted ventilation is usually 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.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Your questions about ventilation duct cleaning in Coleman Green
Do you cover smaller places like Coleman Green?
Yes, Coleman Green is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you come to Coleman Green after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Coleman Green can fit around your hours. Let us know the hours you’re closed and we will book within them.
How much time does a ventilation clean need?
It takes from one overnight visit to a phased programme over several weeks. How much ductwork there is and how easily it’s reached decide the rest.
What if there aren’t enough access panels?
Those sections are recorded as not cleaned in the report, with the reason. New access panels can be installed so they’re covered next time.
What does TR19 Air cover?
TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. TR19® Air takes an inspection-led, risk-based approach.
What does ventilation duct cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a weekend for a modest system, with large buildings phased floor by floor. Seeing the system in photos first means the trip to Coleman Green can be planned properly.
- We survey the system from drawings, photos or a site visit.
- Inspection comes next, with photos of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after photos follow, with anything not reached recorded.
Getting ready for the visit
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Tell us where we can park and unload
Ask for a quote
To get a fixed quote, ring 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.

Honest limits
Before booking, it helps to know what’s not included:
- Ventilation that is undersized for the building
- Leaking or broken duct sections
- Leaks from roofs, pipes or walls into the ductwork
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before you book.
What the work covers
- Supply ductwork
- Offices and schools
- Hospitals and care homes
- Grilles and diffusers
- General extract ductwork
- Toilet extract systems
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Why act early in Coleman Green
If a building in Coleman Green has just been refitted, now is the time to clean the ductwork. Otherwise the dust from the works comes out of the grilles once it’s switched back on. Systems in rural buildings are often out of sight and out of mind.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.

When to call us in Coleman 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.
Signs it’s time to call us include:
- Blocked general extract ductwork
- Dusty supply ductwork that hasn’t been cleaned in years
- Rooms that feel airless when the system runs
- Ventilation that needs a TR19® Air inspection
Healthcare ventilation, from large hospitals like Hill End Hospital (about 3.6 miles south) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When they can work, and whether that’s outside your opening hours
- What records you’ll receive afterwards
- Whether inaccessible sections are listed on the report
What the work involves, part by part
Hospitals and care homes
Patients and residents may be more sensitive to dust in the air. Inspecting and cleaning to TR19® Air supports good air quality.
Schools and colleges
We plan the work around the school calendar, with access agreed with the caretaker or site manager.
