Do you test dampers in schools in Nup End Green during the holidays?
Yes, and it’s the easiest time to do it. Around Nup End Green, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Just call us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you certify fire dampers?
After testing, we provide a report covering each damper, with its location, its result and any faults. Keep it with your fire safety records.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then give us a ring on 0345 646 2711 or drop us a line.

Fire damper testing in Nup End Green, done properly
In a fire, ductwork can act as a shortcut for flame and smoke from one part of a building to the next. That depends entirely on the blade closing all the way. Regular drop testing is how that gets checked in each part of the building. If you have dampers affected by leaks or condensation and gaps in the fire damper test log, we can put it right.
Testing in a small place like Nup End Green is planned around the journey and access, and the test itself is the same as in any city building.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Do you need fire damper testing in Nup End Green?
Over the life of a building, owners, tenants and contractors come and go, and damper records often get lost along the way. Without a register, nobody knows how many dampers there are or when they were last tested.
If you notice any of these, it’s worth a diagnosis:
- Fire dampers with no recent test record
- Dampers that can’t be reached without an access panel
- Corroded dampers in damp risers and plant rooms
- Dampers clogged with dust or grease
If you manage a care home or clinic near Nup End Green, the testing that a hospital like Lister Hospital (about 4.1 miles north) relies on applies to your dampers too.
Before booking anyone

- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Exactly which parts of the system are covered

Leave it or put it right?
Testing every year builds a history for each damper so repeat problems show up early. A damper that was slow last year and sticks this year tells you something long before it fails outright. A planned visit to Nup End Green is easier to arrange than an emergency callout.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
Why us?
- A written report with pictures after every visit
- CHAS, SafeContractor and ISO 9001
- Survey first, then a fixed quote
- One contact for all your sites in London and the South East

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
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. With shared responsibility, good records help everyone.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours for a single floor, with bigger buildings phased over more than one visit. Pictures of the system and its access let us plan the work in Nup End Green before we set off.
- We plan access and timing with you first, including any out-of-hours work.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- We release each blade and check it shuts all the way.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Getting ready for the visit
- Let us know about parking and loading
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What affects the quote in Nup End Green
Your quote is based on your site. We consider:
- The times the site is available
- One-off work versus a regular cycle
- How big the system is
- Any permits to work or inductions
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
Before you ask for a quote, gather:
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- Where the site is and what kind of site it is
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Looking after it afterwards
So the system stays in good health:
- Keep damper test reports with the fire safety log
- Report leaks or condensation near ductwork quickly
- Get remedials done soon after a failed test
- Never wedge or tie a damper open
Dampers we couldn’t reach are listed with the reason, such as no access panel or a blocked hatch. We can fit access panels so they can be tested next time.
Keeping to at least annual testing stops small faults turning into failed dampers. Faults caught early are easier to fix.
