Petts Wood ductwork cleaning
Ductwork cleaning in Petts Wood from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Grease seeping out of the duct seams
- Stale grease odours from the duct
- A duct nobody has opened in years
What happens if it’s left?
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.

About our ductwork cleaning in Petts Wood
Each extract duct we take on in Petts Wood goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and photos complete the record. We are often asked to deal with heavy grease at the base of a riser and years of grease along the duct floor, across horizontal duct runs, access panels and attenuators.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Petts Wood, that usually means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Looking after it afterwards
To keep the system working properly between visits:
- Keep the fan on while anything is cooking
- Ask us about extra access panels where sections cannot be reached
- Tell us if grease leaks from the ductwork
- Make sure filters are seated properly
Grease readings are taken again at the same set points, so the report shows the before and after figures. Before and after photos sit next to the numbers.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Honest limits
In fairness, there are a few things this work won’t fix:
- A damper stuck open in the duct
- A failed fan motor at the end of the duct (a fan repair job)
- Parts of the duct with no way in
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.

Signs you need ductwork cleaning in Petts Wood
Ducts in Petts Wood gather grease for the same reasons as ducts anywhere: hours of cooking, the type of food and how well the filters are kept. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Common reasons sites call us are:
- Grease seeping out of the duct seams
- Proof of duct cleaning for the insurer
- A rancid smell from the extract duct
- Thick crusts of old grease along the duct
If you run a café or takeaway near Petts Wood station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What ductwork cleaning looks like in Petts Wood
The Food Standards Agency lists about 15 pubs and bars as registered food businesses within roughly a mile and a half of the centre of Petts Wood. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Bromley council that sends environmental health officers to food businesses in Petts Wood. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Petts Wood sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Healthcare kitchens, like those at hospitals such as Bridgeways Day Hospital (about 1.5 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. Volunteers running a hall kitchen near St Francis Church, or anywhere in Petts Wood, may not know when the extract was last cleaned, and a grease test settles it.

Fixed quotes for ductwork cleaning in Petts Wood
The diagnosis comes before the price. The main factors are:
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
- Whether several sites go on one quote
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
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 we can price many jobs without a visit.
Common questions in Petts Wood
Do you work at weekends in Petts Wood?
Yes, evening, overnight and weekend work is normal for us. It means the site in Petts Wood keeps running as normal. Your opening times are the first thing we ask for.
Who enforces fire safety at workplaces in Petts Wood?
That is London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What happens if there aren’t enough access panels?
Without a way in, a section cannot be cleaned properly. Those parts are listed, and we can install panels so they’re reached next time.
How often should kitchen ducts be cleaned?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Readings tell you if it needs to be more often.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How long does ductwork cleaning take?
Short runs are quick, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes from a few hours to more than one visit, depending on duct length and access, and the area is cleaned down before we leave. Getting kit into a London building takes planning, so let us know where we can load and park in Petts Wood.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Before we arrive
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
