Ventilation duct cleaning in Croydon, done properly
Ductwork is reached through access panels along each run. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels for the next clean. If you are dealing with rooms that feel airless when the system runs and supply ducts with years of dust inside, we can help.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Croydon, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Protect the system from construction dust
- Report leaks or damp near ceilings and risers
- Keep the TR19 certificate and photo report in the maintenance log
- Wipe grilles and diffusers during routine cleaning
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Put it in the diary now so it isn’t missed.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
Why deal with it now?
A clean system moves air more easily, which puts less load on the fans. Leaving them means the plant works harder for the same result. A building in Croydon may have flats or offices above and alongside, and a fault in the system can affect them too.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

What else we do in Croydon
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes a weekend for a modest system, with large buildings phased floor by floor. Night and weekend working is normal for us in London, and a site in Croydon is no exception.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
How to prepare
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool

Croydon buildings and their air
Food Standards Agency data includes about 34 schools, colleges and universities, about 116 hospitals, care homes and childcare premises and about 20 hotels and B&Bs in Croydon and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The nearest hospital to Croydon is Croydon University Hospital, about 1.7 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.
School buildings such as Heathfield Academy are usually done in the holidays, so classrooms aren’t disturbed. Healthcare ventilation, from large hospitals like Croydon University Hospital (about 1.7 miles north) to small clinics, depends on clean filters, coils and ducts.

What the work involves, part by part
Schools and colleges
Busy classrooms send a lot of dust and fibre into extract ducts. Regular inspection keeps on top of it.
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.
Managing agents and facilities teams in Croydon
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
FAQs for Croydon
Can you come to Croydon after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Croydon doesn’t have to lose a day’s trading. When you ring 0345 646 2711 or email us, mention when the site is quiet.
Can parking be tricky for a job in Croydon?
Tell us where a van can stop near your site in Croydon, and about any building rules on loading. If the building has a loading slot system, we’ll book into it.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
Who has the legal duty for fire safety?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How often do ventilation ducts need cleaning?
Inspection should decide it, in line with TR19® Air. Busy or sensitive buildings may need it more often.
How do you deal with ducts you cannot get into?
Those sections are recorded as not cleaned in the report, so it’s clear what’s outstanding. We can fit new access panels so the whole system can be cleaned.
What if parts of the system cannot be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Do you need ventilation duct cleaning in Croydon?
Damp ducts hold onto dirt. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.
What we’re most often called out for:
- Extract ducts clogged with lint and dust
- Systems missing access panels
- Systems with no record of inspection or cleaning
- Ventilation full of debris from building work
For workplaces around South Croydon station with mechanical ventilation, cleaning can be done in the evening or at weekends.
