Common questions in Baldock
Do you work overnight in Baldock?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you do school kitchen extract cleaning in Baldock in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Baldock, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711, or send details by email, and we will fit the work in.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Which grease filters does the service cover?
We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Grease filter exchange in Baldock
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers mesh filters, wall canopies and school and hospital kitchens, and people most often call us about a canopy that drips grease and filter washing that keeps being missed.
Size does not change the work: a kitchen in a place like Baldock gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What affects the quote in Baldock
The price is fixed before any work begins. It takes into account:
- Whether several sites go on one quote
- How easy every part is to reach
- The times the site is available
- How big the system is
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711, or email photos, and we’ll talk you through it.
Asking for a quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or use the quote form.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
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.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Make sure we can reach the canopy on exchange day
- Watch for grease drips between visits
- Book full TR19 cleans alongside filter changes
- Clean the canopy surfaces regularly
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us for cleaning.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.
How the job changes from site to site
Canopy filter housings
The trough or channel under the filters fills with grease. If it needs attention, we will tell you.
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters, though often more slowly.
When it’s something else
In fairness, there are a few things this work will not fix:
- Grease deep in the extract system
- Odours from the discharge that filters won’t stop
- Extraction problems caused by the fan rather than the filters
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think before you book.
What the work covers

Signs you need grease filter exchange in Baldock
Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Most sites get in touch after spotting something like this:
- Bent or damaged filters that don’t sit properly
- Missing filters in the filter bank
- Poor airflow through the filters
- Filter washing that keeps being missed
Where a hall near Church of St. Mary the Virgin, or anywhere in Baldock, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
