Fire damper testing in Deptford, done properly
In a fire, ductwork can act as a shortcut for flame and smoke from one part of a building to the next. A damper only does its job if the blade can drop fully. Annual drop testing is how you know for the dampers in your building. We’re often asked to deal with dampers clogged with dust or grease and dampers that stick or won’t close fully, across riser dampers, wall and floor dampers and offices and schools.
Many London buildings have been through several fit-outs, and dampers are often left behind new ceilings with no way to reach them. In Deptford, as across London, finding every damper and recording its access is part of the job.
The paperwork matters as much as the work. 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. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
Offices and retail
Each new fit-out brings a risk of damaged or covered dampers. Testing after a fit-out shows whether anything was disturbed.
Ceiling voids and risers
Plant rooms and risers can be damp, which leads to corrosion. We note any rust or water damage on the report so the cause can be tackled.
Common problems we fix in Deptford
Dampers are hidden above ceilings, inside risers and behind boxing. If there’s no hatch to reach them, they slip off everyone’s list, and one that can’t be reached cannot be tested.
Keep an eye out for these warning signs:
- Fire damper items raised by an assessor
- Motorised smoke dampers due for testing
- Dampers clogged with dust or grease
- Dampers hidden with no access panel or hatch
Historic buildings that have had ventilation added later can hide dampers in awkward places; Queen's House, about 1 mile east, is one of the historic houses in the area around Deptford.
Questions to ask before you book
- Whether the quote is based on a survey or photos
- What hours they’ll be on site
- Whether they’re fully insured
- How areas they can’t reach will be recorded
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Managing agents and facilities teams in Deptford
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
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.

FAQs for Deptford
Can the work in Deptford be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you test dampers in schools in Deptford during the holidays?
Yes, holiday work suits schools best. With about 63 schools and colleges on the FSA’s register within roughly a mile and a half of Deptford, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Who has the duty to keep fire dampers working?
Under the Fire Safety Order 2005, it’s the responsible person, such as the employer, owner, landlord or managing agent. Keeping fire safety systems working, dampers included, is part of their duty.
What if a damper has no access panel?
We do not leave it off the report; we note it as not reached. With an access panel fitted, it can be tested on a return visit.
How long will damper testing take?
Typically the work takes from an hour or two in a small building to several visits on a large estate. The number of dampers and how they’re reached decide the rest.
Do you certify fire dampers?
After testing, we provide a report covering each damper, showing where it is, whether it passed and what we found. Keep it with your fire safety records.
Between visits
Here’s the after-treatment advice, short and simple:
- Close off damper faults promptly
- Don’t let anything obstruct a damper’s blade
- Keep ceiling hatches and duct panels easy to open
- Update the register when ductwork changes
Pass the report to whoever keeps your fire risk assessment up to date so their assessment matches what was found. Faults on the report are worth closing off quickly.
A simple register of every damper helps a great deal: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.
The process
We work around your opening hours, not the other way round. 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 Deptford needs from us.
- We go through the damper schedule and any previous faults.
- Each damper is found and checked for access.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
