Fire damper testing in Cannon Hill, done properly
Testing finds the dampers that won’t close. Where a blade sticks, a link is damaged or corrosion has set in, we note it and can quote to repair or replace the damper rather than leaving you with a problem and no fix. We are often asked to deal with fire dampers that haven’t been tested for over a year and rusted damper blades and springs, on riser dampers, wall and floor dampers and fusible link fire dampers.
Plenty of London buildings have been refitted more than once, and dampers can end up hidden above new ceilings with no access panel. Locating each damper in a building in Cannon Hill is the first part of a proper test.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why deal with it now?
Leaving damper testing for another year does not make the dampers any more likely to work. BESA guidance is to test at least annually, and a skipped year leaves a hole in your records as well. A booked night’s work in Cannon Hill costs you no trading time; an unplanned closure does.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

Your questions about fire damper testing in Cannon Hill
Do you do school damper testing in Cannon Hill in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 34 schools and colleges with food registrations within roughly a mile and a half of Cannon Hill. Booking early in the term gives the best choice of holiday dates.
Is parking a problem for work in Cannon Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What information do you need?
A short description and a few photos, with the address and opening hours. We will ask for anything else we need.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How often do fire dampers need drop testing?
At least once a year, under BESA guidance, plus a test when the damper is first installed. Your fire risk assessment may call for some dampers to be tested more often.
Do you need fire damper testing in Cannon Hill?
Building work often happens right next to dampers. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
Keep an eye out for these warning signs:
- Rusted damper blades and springs
- Missing or out-of-date damper records
- Blades that jam part-way when released
- Fire dampers that haven’t been tested for over a year
Historic buildings that have had ventilation added later can hide dampers in awkward places; Southside House, about 1.2 miles north-west, is one of the historic houses in the area around Cannon Hill.

Fire damper testing around Cannon Hill
Food Standards Agency records list about 34 schools, colleges and universities, about 42 hospitals, care homes and childcare premises and about 4 hotels and B&Bs registered as food businesses across Cannon Hill and its immediate surroundings (about a mile and a half). Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. St. Anthony's Hospital is the nearest hospital, about 1.5 miles south of Cannon Hill. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have. In a London building, dampers are often spread across floors and risers, and testing is usually planned out of hours.
Wherever there are offices above shops, near South Merton station or elsewhere in Cannon Hill, ductwork may cross fire-resisting floors, and any dampers need testing. St. Anthony's Hospital, about 1.5 miles south of Cannon Hill, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a few hours for a single floor, with bigger buildings phased over more than one visit. We fit London jobs around the building rather than the other way round, so a visit in Cannon Hill is typically out of hours.
- We start with whatever records exist: registers, drawings or old reports.
- We find every damper and open it up through the access panel.
- Fire dampers are drop tested and smoke dampers are run through their controls.
- Dampers that close fully are reset and left open.
- The results go into a report, with failed dampers and remedials listed.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading

Part by part
Ceiling voids and risers

Smoke dampers
A smoke damper that does not respond to its controls is recorded as a fault, with a note of what we found.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
