Grease filter exchange in Brook, Surrey
Our technicians work in Brook on grease filter exchange. Fixed quotes, work around your opening hours and photo reports on every job.
- Damaged filters letting grease past
- Grease filters clogged with grease
- A canopy running with filters missing
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Grease filter exchange for kitchens and businesses in Brook
A filter that does not sit right lets grease straight past. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. We point out any that need replacing. If you’re dealing with damaged filters letting grease past and grease left in baffles after washing, we can put it right, from wall canopies, restaurants and pubs and mesh filters onwards.
In a village or hamlet like Brook, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
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 Brook
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a short visit, depending on how many filters the canopies hold. Visits to a village like Brook are booked in advance, at a time that suits whoever runs the site.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
Ask for a quote
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What we are called out for in Brook
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.
What we are most often called out for:
- Filters so greasy the air can barely pass
- Grease dripping from the canopy
- Grease building up behind the canopy filters
- Filters that leave gaps in the canopy
School kitchens, at schools like King Edward's School Witley for example, are typically cleaned in the holidays so no lunches are lost.
What to look for in a quote
- How VAT is shown on the quote
- Whether the whole system is included, or only the parts that are easy to reach
- If they look at the system before pricing
- What records you’ll receive afterwards
How we price grease filter exchange
We do not publish a price list, because no two systems are the same. What we look at:
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- How many systems or sites are involved
- A single visit or a regular plan
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
What to send for a quote
To help us quote quickly, send us:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Looking after it afterwards
Once we have finished, these simple steps help:
- Do not let the full clean slip because filters are changed
- Always run the extract while cooking
- Wipe the outside of the canopy as part of daily cleaning
- Keep the canopy clear for exchange visits
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us to be cleaned.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
