What the work involves, part by part
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Vertical risers
Risers carry the extract up through the building. Grease can drain down and pool at the bottom, so the base is a key test point.
How we handle TR19 inspection in Hornchurch Marshes
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Hornchurch Marshes and across Greater London a clear record of the system’s condition. We are often asked to deal with extracts that may be over the 200 micron mean and sites with gaps in their extract records, on access surveys, deposit thickness tests and wet film thickness tests.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Hornchurch Marshes, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Common questions in Hornchurch Marshes
Does London parking affect a job in Hornchurch Marshes?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can school kitchens in Hornchurch Marshes be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 15 schools, colleges and universities with registered kitchens within about a mile and a half of Hornchurch Marshes. Tell us your holiday dates and we’ll book the visit for when the site is empty.
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’re fully insured.
What does a pre-clean survey involve?
We survey, measure and photograph the system first. The survey can be done from pictures and details or on site, whichever suits the system.
At what point does grease need cleaning?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning right away.
Do you cover Hornchurch Marshes?
Yes. Our area takes in London and the counties of South East England, Hornchurch Marshes included.
Is a quote from photos possible?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
When something else is needed
Some problems need a different service or another trade:
- Fan breakdowns, which need a repair visit
- Sections with no access, until panels are fitted
- Ductwork that was designed or installed badly
If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Before any visit in Hornchurch Marshes, we agree where the van can stop and how equipment reaches the system.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
Getting a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Why act early in Hornchurch Marshes
A check after cleaning shows whether the work reached every part it should have, while there’s still time to put anything right. It’s better booked as a planned job in Hornchurch Marshes than handled as an emergency.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Grease, kitchens and Hornchurch Marshes
The FSA’s data shows about 8 pubs, bars and clubs registered within roughly a mile and a half of the centre of Hornchurch Marshes. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Hornchurch Marshes get their food hygiene inspections from Havering council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Hornchurch Marshes is London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a historic house or estate in the area (Rainham Hall is about 1.1 miles east), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like Erith and District Hospital about 2.8 miles south, the extract may need cleaning more often than a part-time kitchen.

When to call us in Hornchurch Marshes
Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Any of these means the system needs a check-up:
- Confirming a clean reached the whole system
- An insurer’s request for a TR19 audit
- Sites with gaps in their extract records
- Extracts that have never been grease tested
Church and community hall kitchens, near Church of St Helen and St Giles or anywhere around Hornchurch Marshes, are easy to forget, but their extracts collect grease like any other.
