Fire damper testing in Colindale, done properly
Each damper we test gets a location, a result and a note of its condition. Passes are reset and left ready to work, while failures are flagged with what we found. That record belongs with the building’s fire safety paperwork. If you have dampers clogged with dust or grease and smoke dampers with no recent test, we can put it right, from riser dampers, motorised smoke dampers and wall and floor dampers onwards.
Across London, buildings with ducted ventilation have a fire damper wherever a duct crosses a fire-resisting wall or floor. A taller building in Colindale can have dampers spread across risers, plant rooms and ceiling voids.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What happens if it’s left?
When something goes wrong, people ask what checks were in place. Damper test records are part of that answer, and you can only produce records for tests that took place. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.

When it’s something else
Fire damper testing cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Deciding where dampers should be fitted
- Missing dampers that a designer needs to specify
- Signing off a building’s overall fire safety
If you’re not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer before booking.

Part by part
Schools, hospitals and care homes
Buildings where people sleep or need help to leave rely heavily on compartments holding fire back. Regular damper testing supports that.
Fusible link fire dampers
For dampers closed by a spring, BESA guidance is annual testing as a minimum. A weak spring or a sticking blade shows up when the damper is dropped.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Keep damper test reports with the fire safety log
- Fix water leaks in plant rooms and risers promptly
- Don’t let hatches get painted shut or boarded over
- Add new dampers to the register as they’re fitted
Failed dampers are set out separately, each with the fault we found, along with an offer to repair or replace them. Once the work is done, the damper is tested again and the record updated.
A simple register of every damper helps a great deal: location, type, last test date and result. It stops dampers getting lost as the building changes.
Fire damper testing in Colindale: local notes
There are about 39 schools, colleges and universities and about 46 hospitals, care homes and childcare premises on the FSA’s food hygiene register within 1.5 miles or so of the middle of Colindale. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Colindale’s nearest hospital, Edgware Community Hospital, is about 1.3 miles north-west. Hospitals are a good example of a building with fire dampers across many floors and departments. London Fire Brigade covers Colindale. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.
Historic houses near Colindale, with Heath Hall about 3.5 miles east, are a reminder that older buildings can hold dampers in unexpected places. Edgware Community Hospital, about 1.3 miles north-west of Colindale, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

Do you need fire damper testing in Colindale?
Buildings in Colindale change owners, tenants and maintenance contractors over the years, and the damper records don’t always go with them. With no register, it’s hard to say how many dampers exist, let alone when they were tested.
These are the problems we see most often:
- Missing or out-of-date damper records
- Rusted damper blades and springs
- Dampers clogged with dust or grease
- Dampers overdue for their annual drop test
School buildings such as Colindale Primary School are typically tested in the holidays, wherever they have dampers.
Before booking anyone
- How areas they can’t reach will be recorded
- Whether the figure could change on the day
- Whether VAT is included
- Which accreditations they hold, and whether you can check them
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
How the visit 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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours for a few dampers, and a day or more across a big site. Security desks and permits-to-work are routine in London, so let us know what your building in Colindale needs from us.
- We start with whatever records exist: registers, drawings or old reports.
- Each damper is located and reached through its access panel.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- Each one that passes is reset, ready to work.
- We report on every damper, with faults and suggested remedials set out.
Before we arrive
- Clear loose items from the work area
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
