Fire damper testing for kitchens and businesses in Lea Valley
Responsible persons, facilities managers and managing agents call us when damper testing falls due in Lea Valley. Send us the damper schedule or the drawings if you have them, and we’ll plan the visit around the building’s hours. The work covers wall and floor dampers, hospitals and care homes and motorised smoke dampers, and the jobs we see most are dampers that can’t be reached without an access panel and smoke dampers with no recent test.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. The first visit starts by locating each damper.
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, with full insurance on top.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
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.
FAQs for Lea Valley
Do you do school damper testing in Lea Valley in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Lea Valley. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you work overnight in Lea Valley?
Yes, out-of-hours work is a big part of what we do. The work in Lea Valley can fit around your hours. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What does fire damper testing cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
What paperwork do we get after testing?
After testing, we provide a report covering each damper, with its location, its result and any faults. Keep it with your fire safety records.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What affects the quote in Lea Valley
Sites vary more than people expect. What affects the quote:
- Whether several sites go on one quote
- How big the system is
- Working hours and out-of-hours timing
- Site rules, permits and inductions
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Helping us quote
When you call or email, these details help:
- The times we could work without disrupting the site
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Why act early in Lea Valley
A sticking blade caught on an annual test can be a small repair. Years of corrosion and dirt can mean the whole damper needs replacing instead. Somewhere as small as Lea Valley, losing a kitchen or building to a fault is felt by everyone who uses it.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What you get with us
- Accredited under CHAS and SafeContractor, with ISO 9001
- We diagnose before we treat
- Work around your opening hours, with 24/7 emergency cover
- Ventilation hygiene specialists since 2009
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building around the people who use them.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Common problems we fix in Lea Valley
Dust settles on damper blades, runners and springs over the years. Where the duct carries grease or cooking vapour, grease coats them too, and either one can hold the blade part-open.
Common reasons sites call us are:
- Dust or grease build-up on damper blades
- Motorised smoke dampers due for testing
- Missing or out-of-date damper records
- Dampers hidden with no access panel or hatch
School buildings such as High Beeches Primary School are usually tested in the holidays, wherever they have dampers.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a few hours for a single floor, with bigger buildings phased over more than one visit. A few pictures of the system help us make the most of a visit to a place like Lea Valley.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
