Ventilation duct cleaning in Penn Street
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. The work covers hospitals and care homes, grilles and diffusers and general extract ductwork, and people most often call us about duct runs that can’t be reached for cleaning and toilet and washroom extracts full of fluff.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
What we are called out for in Penn Street
Many systems run for long hours, day after day, and every hour of running brings more dust with it. Heavier use means faster build-up.
If you notice any of these, it’s worth a diagnosis:
- Blocked general extract ductwork
- Ducts that need a clean before handover
- Damp or stale smells from grilles
- Dust marks around grilles and ceiling diffusers
School buildings such as Curzon Church of England Combined School are normally done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- Whether the work can be done while the site is closed
- If the quote is a fixed price or an estimate
- Whether a written report and photos are included
- Whether VAT is included
How the visit works
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, tidy up and leave you the report. The visit itself takes a day or less for a small system and a series of visits for a large one. Photos of the system and how to reach it help us plan a visit to Penn Street.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Arrange a key holder or contact on site
Ask for a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, ring 0345 646 2711, or email photos.

Do you clean school ventilation in Penn Street in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Penn Street. Booking early in the term gives the best choice of holiday dates.

Do you look at the system first?

Do you clean grilles and diffusers?
Yes, together with the ductwork. You will see them in the before and after pictures.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
When it’s something else
In fairness, some problems need a different fix:
- Leaks from roofs, pipes or walls into the ductwork
- Building management settings that run the plant
- Design problems with the ductwork layout
If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think before you book.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Store cleaning certificates where auditors can find them
- Make sure nothing is stacked against extract grilles
- Keep grilles and diffusers dusted
- Diary the next TR19® Air inspection
What was cleaned is listed, along with any parts that weren’t accessible, backed up by before and after photos. We will suggest where new access panels would help.
Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.
What affects the quote in Penn Street
Your quote is based on your site. We consider:
- The times the site is available
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
What we need to know
We can often survey from pictures. The most useful are:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
Some systems can be priced from pictures; 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.
