Why it’s worth doing now in Nalderswood
Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. In a small place like Nalderswood, a system that fails can take a site out of use.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

About our grease filter exchange in Nalderswood
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. Typical jobs include a canopy running with filters missing and a greasy plenum behind the filters, across school and hospital kitchens, mesh filters and wall canopies.
In a small place like Nalderswood, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Nalderswood questions
Which environmental health team covers Nalderswood?
That is Mole Valley council, whose environmental health officers carry out food hygiene inspections in Nalderswood. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Which fire and rescue service is responsible for Nalderswood?
That’s Surrey Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Which grease filters does the service cover?
Baffle and mesh filters are both covered. We check what’s in your canopies first and set up the service around them.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Part by part
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Regular changes help protect the ductwork.
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. We agree the schedule to match.
In-house cleaning or a specialist?
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, and that’s where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. Somewhere like Nalderswood, lanes, gates and parking are worth mentioning in advance.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Before we arrive
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.

Common problems we fix in Nalderswood
What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
What we are most often called out for:
- Grease dripping from the canopy
- Filters that come out of the sink still dirty
- Filters so greasy the air can barely pass
- Damaged filters letting grease past
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Nalderswood is East Surrey Hospital, about 3.7 miles north-east.
Comparing quotes
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system can’t be accessed
- When the next visit should be, and why
- Proof of insurance
When something else is needed
Some problems need a different service or another trade:
- Cooking smells reaching neighbours, which need odour control
- Grease deep in the extract system
- A noisy or failed extract fan
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think before booking.

Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Mention it if the kitchen gets busier
- Clean the canopy surfaces regularly
- Tell us if a filter is bent or damaged
- Keep the canopy clear for exchange visits
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to keep up.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule keeps everything on track.
Grease, kitchens and Nalderswood
Fire safety in Nalderswood falls to Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Mole Valley council inspect food businesses in Nalderswood. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Term dates shape school work: for a school like Burys Court School, an extract clean fits neatly into a half-term or summer break. Where a hall near Church of St Bartholomew, or anywhere in Nalderswood, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
