Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Ventilation duct cleaning in Westmill
In a building in Westmill, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, alongside filter changes and AHU maintenance. The work covers supply ductwork, grilles and diffusers and offices and schools, and common reasons people get in touch are extract ducts clogged with lint and dust and stuffy rooms and stale air.
Work in a small place like Westmill starts with agreeing access and timings.

Westmill: your questions answered
Can you work in Westmill outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Westmill keeps running as normal. Your opening times are the first thing we ask for.
Will you come out to Westmill?
Yes, Westmill is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
When should our ventilation next be cleaned?
There’s no single interval; under TR19® Air, inspection decides. We suggest a next inspection date after each visit.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
How much does ventilation duct cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll usually reply within one working day.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from a single shift for a small office to a planned programme of nights for a large building, and the area is cleaned down before we leave. If the van will struggle with a lane or gateway near Westmill, let us know and we’ll plan around it.
- We survey the system from drawings, pictures or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
- Tell us where we can park and unload

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
Advice
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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 is where we come in.
What the work involves, part by part
Extract ductwork
A dirty extract duct makes its fan work harder. A clean duct takes the load off.
Offices and retail
Multi-let buildings may share ductwork between tenants. Access is agreed with the building manager.
What affects the quote in Westmill
You’ll get a fixed price before any work starts. It’s based on:
- One-off work versus a regular cycle
- Where the site is and how we reach it
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- The times we could work without disrupting the site
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Wide photos of the system and the area around it
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or send us an email.
When to call us in Westmill
Filters never catch everything, so fine dust settles in supply ductwork over the years. Extract ducts pick up dust, fibres and fluff from the rooms they serve.
Common reasons sites call us include:
- Duct runs that cannot be reached for cleaning
- Ventilation that needs a TR19® Air inspection
- Dusty supply ductwork that hasn’t been cleaned in years
- Ventilation full of debris from building work
School buildings such as Freman College are typically done in the holidays, so classrooms are not disturbed.
What to look for in a quote
- Proof of insurance
- How they set the interval to the next visit
- How areas they cannot reach will be recorded
- Whether the work can be done while the site is closed
