Ventilation duct cleaning in Downham, done properly
Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts carry anything the filters miss. Both are cleaned, with the area protected and the mess contained. The work covers supply ductwork, hospitals and care homes and general extract ductwork, and people most often call us about construction dust left in ducts after a refit and duct runs that can’t be reached for cleaning.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Downham, as elsewhere, cleaning starts with an inspection of what’s there.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why it’s worth doing now in Downham
After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we will explain what it covers.

Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Common questions in Downham
Can parking be tricky for a job in Downham?
Tell us where a van can stop near your site in Downham, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Can you come to Downham after we close?
Yes, nights and weekends are routine for us. It means the site in Downham keeps running as normal. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you clean grilles and diffusers?
Yes, together with the ductwork. You will see them in the before and after pictures.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do we need to close while you work?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Do you survey the system first?
Yes. Inspection is the start of the TR19® Air approach and record what we find. We recommend cleaning where the inspection shows it’s due.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What the work involves, part by part
Schools and colleges
We plan the work around the school calendar, with access agreed with the caretaker or site manager.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, so the dust tends to cling. They’re cleaned and their condition recorded.

What staff can safely do
A few tasks are always specialist work: 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.
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Keep the TR19 certificate and photo report in the maintenance log
- Stick to the filter change schedule
- Tell your facilities team about dirty diffusers
- Watch for water stains around grilles
The report includes a recommended date for the next inspection, based on what we found. Diary it right away so it does not slip.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
Common problems we fix in Downham
Building work is one of the biggest sources of debris in ducts, especially when the system runs during the work. Plaster, wood and masonry dust can sit in the ducts for years.

- Dusty supply ductwork that hasn’t been cleaned in years
- Damp or stale smells from grilles
- Dust marks around grilles and ceiling diffusers
- Construction dust left in ducts after a refit
If you manage offices or shops near Grove Park station, their ventilation can be inspected and cleaned out of hours.
