Fire damper testing in Rush Green, done properly
BESA guidance is that fire dampers should be tested by a competent person when they’re installed and at least annually after that. Spring-operated dampers need testing every year as a minimum. Our job is to do the testing and hand you the paperwork that shows it. The work covers motorised smoke dampers, riser dampers and hospitals and care homes, and people most often call us about damper actions from a fire risk assessment and corroded dampers in damp risers and plant rooms.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. A first test usually starts with finding them all.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

When something else is needed
Not every problem is solved by fire damper testing, and we will tell you before any work starts. It does not solve:
- Fire-stopping gaps around the duct where it passes through the wall
- Ductwork crossing a fire wall with no damper fitted
- Approving the building’s fire strategy
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
Parts of the system we cover
- Wall and floor dampers
- Riser dampers
- Offices and schools
- Hospitals and care homes
- Motorised smoke dampers
- Fusible link fire dampers
Between visits
So the system stays in good health:
- Diary the annual test well ahead
- Store test records alongside the fire risk assessment
- Don’t let hatches get painted shut or boarded over
- Add new dampers to the register as they’re fitted
The next test should be no more than a year away. BESA guidance is at least annual testing, so it helps to book it before the date slips.
Water is a damper’s enemy, so fix leaks and condensation near them promptly. Rusted parts are one of the main reasons dampers fail to close.
What the work involves, part by part
Fusible link fire dampers
Spring-operated fire dampers need testing at least once a year. A weak spring or a sticking blade shows up when the damper is dropped.
Offices and retail
In shared buildings, some dampers sit inside tenants’ space. Access to each area is planned with whoever manages the building.

What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from a couple of hours for a handful of dampers to a full day for a large building, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Rush Green.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Dampers that pass are reset, and failures are logged with what we found.
- We report the results and offer remedials on failed dampers.
Preparing for the visit
- Clear the space around the work
- Let us know when the site is closed or quiet
- Tell us where we can park and unload

Advice
Rush Green buildings and fire safety
About 28 miles out from central London, Rush Green is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Rush Green sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty.
Lister Hospital, about 2.2 miles north-east of Rush Green, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests. For schools like The Thomas Alleyne School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

Do you need fire damper testing in Rush Green?
Rust is a frequent reason a damper won’t close. Water leaks, condensation and damp plant areas attack the casing, blade and spring, so a damper can seize without anyone noticing.
Look out for these warning signs:
- Dampers hidden with no access panel or hatch
- Fire dampers that haven’t been tested for over a year
- Fire dampers that fail to drop shut
- Dampers affected by leaks or condensation
Knebworth House, about 2.1 miles south-east, is one of the historic houses near Rush Green, and older buildings converted to new uses often have ventilation added later.
Questions to ask before booking

FAQs for Rush Green
Who enforces fire safety at workplaces in Rush Green?
Rush Green is in the area of Hertfordshire Fire and Rescue Service. BESA guidance is that every fire damper is tested at least once a year, so an officer or insurer may expect a report less than a year old.
Do you work overnight in Rush Green?
Yes, we can come after you close and finish before you open. That way a site in Rush Green doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What happens to dampers you cannot get to?
We record it as not tested and explain why. We can fit an access panel so the damper can be tested next time.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call us on 0345 646 2711, or email photos.
Is a quote from pictures possible?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Fixed quotes for fire damper testing in Rush Green
Before we fix a price, we need to know a few things. We look at:
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- Site requirements such as sign-in and permits
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 we start.
What we need to know
When you contact us, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, call 0345 646 2711 or send us an email.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
