Sudbury questions
Can the work in Sudbury be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Sudbury doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can ventilation in schools around Sudbury be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 27 schools, colleges and universities with registered kitchens within about a mile and a half of Sudbury. Booking early in the term gives the best choice of holiday dates.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Is TR19 cleaning required by law?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How often do ventilation ducts need cleaning?
That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.
Ventilation duct cleaning in Sudbury
Inspection comes first. The ducts are opened at access points and the condition recorded, and cleaning is recommended where the inspection shows it’s due. That way the work matches the real condition. Common call-outs are for toilet and washroom extracts full of fluff and supply ducts with years of dust inside, on supply ductwork, grilles and diffusers and general extract ductwork.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Sudbury is normally planned out of hours. Loading and parking are planned with the building first.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a day or less for a small system and a series of visits for a large one, and we clear up before we go. A name and number for whoever controls access to the building in Sudbury saves time on the night.
- First the system is surveyed, on site or from photos and drawings.
- Ducts are inspected at access points and the condition recorded.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after pictures follow, with anything not reached recorded.
Before we arrive
- Mention any parking or loading restrictions
- Move anything stored near the system
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
Signs you need ventilation duct cleaning in Sudbury
Ductwork is hidden above ceilings and in risers, so dust collects unseen. Grilles may be wiped, but the ducts behind them rarely are.
It’s time to book a visit if you see:
- Ventilation full of debris from building work
- Systems missing access panels
- Toilet and washroom extracts full of fluff
- Stuffy rooms and stale air
Workplaces around Sudbury & Harrow Road station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

- Whether the quote is based on a survey or photos
- What paperwork you get at the end
- How areas they can’t reach will be recorded
What a clean will not put right
In fairness, there are a few things this work will not fix:
- Controls and BMS faults that affect the system
- Ventilation that is undersized for the building
- Leaks from roofs, pipes or walls into the ductwork
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.

Staff cleaning versus specialist work
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.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Different parts, different methods
Schools and colleges
Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.
Hospitals and care homes
In care settings, keeping dust contained is a priority. The area is protected, and debris contained and removed.
Why act early in Sudbury
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 booked night’s work in Sudbury costs you no trading time; an unplanned closure does.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
