Grease trap cleaning for kitchens and businesses in Sandridge
Grease trap cleaning keeps the drains running and the smells away. The fat, oil, grease and solids are taken out and the chambers and baffles cleaned, and check the trap is working properly. The work covers kitchen waste pipes, restaurants and takeaways and under-sink grease traps, and people most often call us about a small trap that fills too quickly and a kitchen drain that smells.
For a kitchen in or near Sandridge, the visit is planned ahead, around opening times and the journey, and the deep clean is the same as anywhere: walls, floors, ceilings and equipment.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Different parts, different methods
Inline grease traps
Inline traps often take waste from several sinks or appliances. More waste means faster filling.
Under-sink grease traps
An under-sink trap is out of sight. A full one shows itself with a slow, smelly sink.
The process
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. On site, the work takes an hour or so for an under-sink trap, longer for a larger unit. A few photos of the system help us make the most of a visit to a place like Sandridge.
- We locate the trap and check how it’s fitted.
- We make sure nothing drains into the trap.
- Grease and solids are removed from the trap.

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Related advice
Sandridge: your questions answered
Who carries out food hygiene inspections in Sandridge?
Food hygiene inspections in Sandridge are carried out by St Albans City council. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
Will you come out to Sandridge?
Yes, we work in villages as well as towns, and Sandridge is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you give me a price for grease trap cleaning?
The price depends on the trap and the schedule. Just call us on 0345 646 2711, or email photos and we will quote before any work starts.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
How regularly does a grease trap need emptying?
The right interval depends on your trap and your cooking. Slow or smelly sinks between cleans mean it needs doing more often, and we can shorten it.
What should go in our maintenance log?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. A fixed quote follows.
Will you tell us when the next visit is due?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Hot water only moves grease further down
- Book trap cleans at a set interval
- Act on gurgling or smelly drains
- Tell us if your menu or hours change
If we spot problems beyond the trap, such as a drain that still runs slowly, we’ll tell you. That may need a drainage contractor to investigate.
An overfull trap lets grease pass. Regular emptying keeps it working and avoids a blockage.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
When it’s something else
Before booking, it helps to know what’s not included:
- Drains that need jetting rather than trap cleaning
- Broken pipework below ground
- Blockages further down the drainage network
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before booking.

What grease trap cleaning looks like in Sandridge
There are about 12 restaurants, cafés and works canteens and about 9 takeaways and sandwich shops within 1.5 miles or so of the middle of Sandridge, according to the Food Standards Agency’s register. Wherever they wash pans and plates, fat heads for the drain unless a trap catches it. Food hygiene inspections in Sandridge are the job of St Albans City council’s environmental health team. They look at the cleanliness of the whole kitchen: walls, floors, ceilings and equipment. A record of each deep clean helps show the kitchen is kept in order.
If you run a church or community hall kitchen, near St Leonard's Church or elsewhere in Sandridge, a deep clean and an emptied grease trap before a busy season of events are worth booking. School kitchens, at schools like Sandridge School for example, typically have their deep cleans and grease trap work done while the canteen is closed. Childwickbury Manor, about 2 miles west, is one of the historic houses around Sandridge; event kitchens at places like that work in bursts, so a deep clean after a busy season helps.
