Ventilation duct cleaning in Great Waltham
Every clean ends with a TR19® certificate and a photo report. It shows what was cleaned, anything we couldn’t reach and when the system should next be inspected, so you have it all on record. The work covers grilles and diffusers, toilet extract systems and general extract ductwork, and the jobs we see most are ductwork with too few access panels to clean and dust marks around grilles and ceiling diffusers.
Somewhere as small as Great Waltham, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Fixed quotes for ventilation duct cleaning in Great Waltham
Your quote is based on your site. We take into account:
- What state the system is in
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- A single visit or a regular plan
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- The postcode and the type of business
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Make sure nothing is stacked against extract grilles
- Tell your facilities team about dirty diffusers
- Book the next inspection on the date the report recommends
- Keep the TR19 certificate and photo report in the maintenance log
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 is not missed.
Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.
Different parts, different methods
Supply ductwork
Supply ductwork delivers conditioned air to each room. Dust that slips past the filters builds up inside, and it’s cleaned out through access panels.
Offices and retail
Fit-outs in offices and shops leave dust in the ventilation. A clean before handover is a sensible step.
The process
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. A few photos of the system help us make the most of a visit to a place like Great Waltham.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
Before we arrive
- Clear the space around the work
- Let us know when the site is closed or quiet
- Find the previous report, if there is one

Common questions in Great Waltham
Can a school’s ventilation in Great Waltham be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Great Waltham. Booking early in the term gives the best choice of holiday dates.

Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How long does ventilation cleaning take?
Typically, the work takes a shift or two for a small system, longer for a whole building. Bigger sites are split into stages, to fit around the building.
What is TR19® Air?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract is covered separately, by TR19® Grease.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.

What else we do in Great Waltham
Do you need ventilation duct cleaning in Great Waltham?
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.
It’s time to book a visit if you see:
- Dusty supply ductwork that hasn’t been cleaned in years
- Dirty diffusers dropping dust into rooms
- Poor airflow from the vents
- Musty smells from the ventilation
Hospitals such as Broomfield Hospital (about 1.4 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Great Waltham are no different.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If the quote is a fixed price or an estimate
- If they look at the system before pricing
- When the next visit should be, and why
Multi-site and managed buildings
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 also work for facilities teams across offices, schools and healthcare across Essex. Work can be phased by floor, building or site to keep disruption down.
