Osidge fire damper testing
Fire damper testing in Osidge from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Blades that jam part-way when released
- Dampers that cannot be reached without an access panel
- Dampers affected by leaks or condensation
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a morning or an afternoon for a small number of dampers, longer where there are many, and the area is cleaned down before we leave. Before any visit in Osidge, we agree where the van can stop and how equipment reaches the system.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- Fire dampers are drop tested, and smoke dampers are tested through their 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
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive

Advice
Fire damper testing in Osidge, 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. We carry out fire damper testing for buildings in Osidge and give you the records to show it’s been done. The work covers motorised smoke dampers, riser dampers and fusible link fire dampers, and the jobs we see most are fire dampers with no recent test record and fire dampers that fail to drop shut.
Many London buildings have been through several fit-outs, and dampers can end up hidden above new ceilings with no access panel. In Osidge, as across London, finding every damper and recording its access is part of the job.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Why it’s worth doing now in Osidge
Leaving damper testing for another year does not make the dampers any more likely to work. The guidance from BESA is at least once a year, so a missed year leaves a gap in the record too. Leaving it on a busy London site only adds to the work.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Why us?
- We diagnose before we treat
- A fixed price before any work starts
- Each visit written up, with photos
- Accredited under CHAS and SafeContractor, with ISO 9001

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Store test records alongside the fire risk assessment
- Do not let anything obstruct a damper’s blade
- Report leaks or condensation near ductwork quickly
- Update the register when ductwork changes
Share the results with your fire risk assessor so their assessment matches what was found. Faults on the report are worth closing off quickly.
Clean ductwork means less dust and grease reaching the dampers. Duct cleaning and damper testing can be planned side by side.

Ceiling voids are where lots of dampers end up. Ceiling tiles are lifted for access and replaced afterwards.
Osidge questions
Is parking a problem for work in Osidge?
Tell us where a van can stop near your site in Osidge, and about any building rules on loading. Much of our London work is done overnight, which helps.
Do you do school damper testing in Osidge in the summer holidays?
Yes, and it’s the easiest time to do it. With about 48 schools and colleges on the FSA’s register within roughly a mile and a half of Osidge, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. The nearest hospital to Osidge is Coppetts Wood Hospital, about 2.3 miles south. Smaller healthcare sites, from surgeries to care homes, need the same annual damper test as a hospital.
A school like Monkfrith Primary School can have any dampers tested over half-term without disturbing lessons. Coppetts Wood Hospital, about 2.3 miles south of Osidge, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

Well-known places in the area include Broomfield House Museum (1.6 miles south-east) and Grand Arcade (2.1 miles south-west). Not far away are Darland's Lake and Barfield Allotments Nature Park.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
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.
How we price fire damper testing
The survey tells us what the work involves. The main factors are:
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
- How easy every part is to reach
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, call 0345 646 2711 or drop us a line.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
