How it 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 from an hour or two in a small building to several visits on a large estate, and the area is cleaned down before we leave. Security desks and permits-to-work are routine in London, so let us know what your building in Coldharbour needs from us.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
Before we arrive
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards

Advice
Fire damper testing in Coldharbour
Ductwork can carry fire and smoke between compartments, and the damper is what stops it. A damper only does its job if the blade can drop fully. Regular drop testing is how that gets checked for the dampers in your building. If you have fire dampers that fail to drop shut and dampers hidden with no access panel or hatch, we can help.
Many London buildings have been through several fit-outs, and dampers are often left behind new ceilings with no way to reach them. Locating each damper in a building in Coldharbour is the first part of a proper test.
Good records are part of the job. You get a written report with photos after every visit, 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.

Between visits
How long the results last depends on use and care. We suggest:
- Report leaks or condensation near ductwork quickly
- Don’t let anything obstruct a damper’s blade
- Keep damper test reports with the fire safety log
- Act on failed dampers rather than leaving them on file
Share the results with your fire risk assessor, so the assessment reflects where the dampers stand. Faults on the report are worth closing off quickly.
The simplest way to avoid failures is to test on time, every year. A blade that is just starting to stick is easier to deal with than a seized one.

Why deal with it now?
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 before it becomes a failure. It’s better booked as a planned job in Coldharbour than handled as an emergency.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
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. Where responsibility is shared, records matter even more.
Part by part
Ceiling voids and risers
Where ductwork runs up through a building, there are often dampers at every floor. Testing goes floor by floor so nothing is missed.
Smoke dampers
A smoke damper is opened and closed by a motor, not a link. Testing means operating them from the controls to confirm the blade moves all the way.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Fire risk assessments, which need a fire risk assessor
- Dampers that were never installed where they’re needed
- Gaps in the wall or floor around the damper
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 before you book.

Fire damper testing in Coldharbour: local notes
There are about 46 schools, colleges and universities, about 40 caring premises (care homes, nurseries and hospitals) and about 14 hotels and guest houses on the FSA’s food hygiene register within about 1.5 miles of central Coldharbour. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. London Fire Brigade covers Coldharbour. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises. London buildings tend to have dampers on several floors, so testing is normally done out of hours, a zone at a time.
Healthcare buildings such as Poplar Hospital (about 0.6 miles north) rely on fire compartments, and the dampers in them need testing at least annually. Queen's House, about 1.5 miles south, is one of the historic houses near Coldharbour, and older buildings converted to new uses often have ventilation added later. If you manage a school site such as Woolmore Primary School, any fire dampers can be tested in the holidays.

Can you test school fire dampers in Coldharbour out of term?
Yes. Half-terms and the summer break are the natural time for school work.

Who is the responsible person?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How do you keep the site clean during the work?

What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
How long does fire damper testing take?
As a guide, it takes a couple of hours for a few dampers, and a day or more across a big site. It comes down mainly to how many dampers there are and how easy they are to get to.
