Grease trap cleaning in Shenley
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it, then check the water flows properly. If you have sinks that drain slowly and grease setting in the kitchen pipework, we can put it right.
In a place like Shenley, kitchens often sit in older buildings with older drains. Smells and slow drains are the usual warning signs.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common problems we fix in Shenley
A busy kitchen in Shenley, or anywhere else, fills its grease trap faster. A trap that suited a quieter kitchen can fill very quickly when trade picks up.
Common reasons sites call us are:
- A full, neglected grease trap
- Scheduled grease trap emptying
- Foul odours from the grease trap
- Drains that gurgle and bubble
Historic houses such as Wyllyotts Manor (about 4.1 miles east) are part of the area around Shenley, and if you run event catering at a venue like that, a deep clean between seasons helps.

Common questions in Shenley
Do you work in villages like Shenley?
Yes, we work in villages as well as towns, and Shenley is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Shenley?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Shenley needn’t be disturbed. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Where does the grease from the trap go?
We take it away. There’s nothing left for your team to deal with once the clean is done.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.
What happens if a grease trap is not cleaned?
A full trap cannot catch any more grease. It then sets in the drains, causing blockages and smells and can end up adding to sewer blockages.
How we price grease trap cleaning
The price is fixed before any work begins. It takes into account:
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- How easy every part is to reach
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
What to send for a quote:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- Any previous report or certificate
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Managing agents and facilities teams in Shenley
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building around the people who use them.
Between visits
Once we’ve finished, these simple steps help:
- Avoid pouring boiling water down to shift grease
- Make sure the trap can be reached easily
- Do not wait for a blockage to book a clean
- Collect waste cooking oil separately
The waste we remove leaves with us. Nothing is left for you to dispose of when we’re done.
Slow sinks and a bad smell are early warnings. Getting it cleaned now can stop a full blockage later.
What happens if it’s left?
Grease that leaves the kitchen ends up somewhere. It adds to blockages further down the drains and sewer. A well-maintained trap keeps it where it can be removed. A planned visit to Shenley fits your hours; an emergency does not.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Wherever they cook, the kitchen and its drains need the same attention as a restaurant’s. It’s Hertsmere council that sends environmental health officers to food businesses in Shenley.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes less than an hour for many under-sink units. Around Shenley, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- Built-up grease and food waste are taken out.
- We clean the baffles, inlet and outlet.
- The trap is closed, tested and the next clean discussed.
Before we arrive
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
- Allow time for equipment near the work to be turned off and cool down
