What affects the cost of ductwork cleaning
Your quote is based on your site. We consider:
- The size of the system
- A single visit or a regular plan
- Parking and loading at the site
- Whether several sites go on one quote
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
What to send for a quote
Before you ask for a quote, gather:
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
- The postcode and the type of business
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Ductwork cleaning for kitchens and businesses in Crossness
No two duct runs are the same, in Crossness or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. Common call-outs are for smells of old cooking grease from the ductwork and a duct nobody has opened in years, on attenuators, horizontal duct runs and bends and junctions.
London kitchens tend to trade late and open early, so work in Crossness is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Run the extract fan throughout service
- Book the next clean before the recommended date
- Ask us about extra access panels where sections cannot be reached
- Ask for a grease thickness test if the kitchen gets busier
Keep the certificate and report with the fire risk assessment. An insurer, fire officer or EHO may ask to see it, and the photos make the duct’s condition easy to see.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
Grease, kitchens and Crossness
The Food Standards Agency lists about 10 pubs and bars as registered food businesses within 1.5 miles or so of the middle of Crossness. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Crossness are the job of Bexley council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
A hospital like Erith and District Hospital, about 2.1 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Term dates shape school work: for a school like St John Fisher Catholic Primary School, an extract clean fits neatly into a half-term or summer break.
Crossness is about 2 miles north-west of Erith, in Greater London. We provide ductwork cleaning for commercial premises of every kind in Crossness and the rest of Greater London. Crossness is one of 764 places in Greater London we cover for commercial clients. London is in our area too, about 10 miles from Crossness.
We cover every part of the SE2, SE28 and DA18 postcode area for ductwork cleaning and the roads nearby. Whether your site is on Kale Road, Haldane Road and Seacourt Road or anywhere close by, we can help. With the A2016 close by, Crossness is easy for our technicians to reach at any hour. If your site is just outside Crossness, we cover Thamesmead (1 mile north-west), Dagenham Dock (1 mile north), Barking Riverside (2 miles north-west), Hornchurch Marshes (2 miles north-east) and Dagenham Green (2 miles north).

Why it’s worth doing now in Crossness
Booking the duct clean in Crossness now keeps it a planned job. The work takes anything from a few hours to several visits, depending on the length of duct, done out of hours so the kitchen keeps cooking. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why book with us
- One number for every site across the South East and London
- Survey first, then a fixed quote
- CHAS and SafeContractor accredited, with ISO 9001
- Evenings, overnight and weekends, plus 24/7 emergency callout

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from a few hours to several visits, depending on the length of duct. A name and number for whoever controls access to the building in Crossness saves time on the night.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Make sure someone can let us in and lock up afterwards

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

FAQs for Crossness
Who would carry out a food hygiene inspection at a kitchen in Crossness?
Food hygiene inspections in Crossness are carried out by Bexley council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can school kitchens in Crossness be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Around Crossness, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What shows that the ducts need a clean?
Drips, smells and weak extraction are clues, but measuring is the reliable way to know. A WFTT or DTT reading gives a clear answer.
When is the ductwork cleaned?
Only while we’re working, and we work around you. Most kitchens book overnight or weekend cleans, so no service is lost.
How long does ductwork cleaning take?
Short runs are quick, but long or complex ducts may take several visits. Visits are planned out of hours.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
When something else is needed
We will always give you a straight diagnosis, so here’s what ductwork cleaning will not do:
- Parts of the duct with no way in
- Leaking duct joints that need repair
- An extract fan that has stopped working
If in doubt, call us on 0345 646 2711 or email us and we will say what we think.
What we work on in Crossness
- Multi-storey ducts
- Access panels

When to call us in Crossness
A greasy duct is a fire path, in Crossness as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
The symptoms we’re asked about most include:
- Readings above 200 microns from a grease thickness test
- Grease pooling at the foot of the riser
- Hardened, baked-on grease in long horizontal runs
- Grease seeping out of the duct seams
Volunteers running a hall kitchen near Church of the Cross, or anywhere in Crossness, may not know when the extract was last cleaned, and a grease test settles it.
Questions to ask before you book
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What paperwork you get at the end
- When the next visit should be, and why
- If the quote is a fixed price or an estimate
