Grease filter exchange in Tisman's Common, done properly
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. The work covers baffle filters, wall canopies and mesh filters, and people most often call us about hand-washed filters that still look greasy and drips falling from the filters onto equipment.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
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, with full insurance on top.

FAQs for Tisman's Common
Who enforces fire safety at workplaces in Tisman's Common?
Fire safety enforcement in Tisman's Common is handled by West Sussex Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who would carry out a food hygiene inspection at a kitchen in Tisman's Common?
Kitchens in Tisman's Common are inspected by Horsham council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Will I get paperwork for my records?
Yes. Every visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
How regularly do grease filters need exchanging?
It depends on how much and what the kitchen cooks. Heavy cooking means more frequent changes than kitchens that cook less. We set a schedule that suits your kitchen.
Which grease filters does the service cover?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so the clean set always fits.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
Does the report say when we need you again?
Yes. The report recommends when the next visit should be, based on what we found and how the system is used.

What else we do in Tisman's Common
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes a short visit, depending on how many filters the canopies hold. Pictures of the system and its access let us plan the work in Tisman's Common before we set off.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At every visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time

Why it’s worth doing now in Tisman's Common
Washing filters in-house is an option for kitchens in Tisman's Common, and it works when it’s done well and never skipped. When it does not happen reliably, an exchange makes it automatic. Rural sites cannot always move to another kitchen or room when something fails.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Managing agents and facilities teams in Tisman's Common
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
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.
