When to call us in Underling Green
Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.
Signs it’s time to call us include:
- Grease dripping from the canopy
- Weak extraction at the canopy
- Blocked baffle filters
- Staff short of time to wash filters
If you run catering at a historic house or estate in the area (Stoneacre is about 5 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.

Grease filter exchange in Underling Green
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. A steady cycle of clean filters keeps extraction strong. If you are dealing with filters that come out of the sink still dirty and filters left unwashed on busy weeks, we can put it right.
For a kitchen in or near Underling Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, as 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 else we do in Underling Green
Underling Green: your questions answered
Do you cover smaller places like Underling Green?
Yes, Underling Green is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Underling Green after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Underling Green needn’t be disturbed. Your opening times are the first thing we ask for.
What accreditations do you have?
Our accreditations are 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.
What if some of our filters are damaged?
A bent filter leaves a gap for grease. We point them out on the visit so they can be replaced.
How regularly do grease filters need exchanging?
The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.
What types of filter do you exchange?
Baffle filters and mesh filters. Tell us what you have when you call 0345 646 2711 or use the quote form and we’ll confirm it on site.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What affects the cost of grease filter exchange
Your quote is based on your site. We take into account:
- How big the system is
- Where the site is and how we reach it
- How many systems or sites are involved
- Site rules, permits and inductions
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 work begins, so there are no surprises.
Helping us quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Tell us if a filter is bent or damaged
- Clean the canopy surfaces regularly
- Mention it if the kitchen gets busier
- Make sure no filter is left out
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
Leave it or put it right?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job and grease readings can rise between cleans. Somewhere as small as Underling Green, losing a kitchen or building to a fault is felt by everyone who uses it.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work are not the same thing. 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.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
We also work for facilities teams across offices, schools and healthcare across Kent. Work can be phased by floor, building or site around the people who use them.
