Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
About our fire damper testing in Mortlake
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 in each part of the building. The work covers hospitals and care homes, fusible link fire dampers and motorised smoke dampers, and common reasons people get in touch are fire dampers with no recent test record and dirty dampers that may not close.
Plenty of London buildings have been refitted more than once, and dampers can end up hidden above new ceilings with no access panel. In Mortlake, 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 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.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a few hours for a single floor, with bigger buildings phased over more than one visit. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Mortlake.
- First we look at any damper register, drawings or earlier test reports.
- Dampers are located one by one and reached through their access panels.
- We release each fire damper blade and operate smoke dampers from their controls.
- Each one that passes is reset, ready to work.
- The results go into a report, with failed dampers and remedials listed.
Getting ready for the visit
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.

What fire damper testing can’t fix
Some problems need a different service or another trade:
- Gaps in the wall or floor around the damper
- Designing the building’s fire compartments
- Faults in the alarm or building controls that signal smoke dampers
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think before booking.
Parts of the system we cover
- Hospitals and care homes
- Riser dampers
- Motorised smoke dampers
- Offices and schools
- Wall and floor dampers
- Fusible link fire dampers
What happens if it’s left?
If a damper cannot close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. It’s far better to find that out on a test than in a fire. A booked night’s work in Mortlake costs you no trading time; an unplanned closure does.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What affects the quote in Mortlake
A fixed price needs a few facts first. We look at:
- The number of sites or systems
- Site rules, permits and inductions
- Working hours and out-of-hours timing
- Parking and loading at the site
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
Need a price for fire damper testing? Please ring 0345 646 2711, or email photos with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Looking after it afterwards
After the visit, a few habits help the work last:
- Close off damper faults promptly
- Tell contractors where dampers are before they start work
- Keep cables and fixings away from damper blades
- Don’t let hatches get painted shut or boarded over
Failed dampers are set out separately, each with the fault we found, along with an offer to repair or replace them. After a repair, we retest the damper and update the record.
Water is a damper’s enemy, so fix leaks and condensation near them promptly. Rusted parts are one of the main reasons dampers fail to close.
Questions from Mortlake
Does London parking affect a job in Mortlake?
Tell us where a van can stop near your site in Mortlake, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Can you come to Mortlake after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just phone us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Do we lose a day’s trading?
Normally not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What fire damper testing looks like in Mortlake
Food Standards Agency records list about 16 schools, colleges and universities and about 21 caring premises (care homes, nurseries and hospitals) registered as food businesses within 1.5 miles or so of the middle of Mortlake. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. For Mortlake, the closest hospital is Barnes Hospital, roughly within half a mile east. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed. The fire and rescue service for Mortlake is London Fire Brigade. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you manage an older building converted to a hotel or venue, like many historic houses in the area (Chiswick House is about 1.3 miles north), finding every damper is the first job. School buildings such as Thomson House School are typically tested in the holidays, wherever they have dampers.

What we’re called out for in Mortlake
Dust settles on damper blades, runners and springs over the years. If the duct carries cooking vapour, a film of grease adds to it, and either can stop the blade dropping fully.
Clients usually contact us when they notice something like this:
- Fire dampers that haven’t been tested for over a year
- Dust or grease build-up on damper blades
- Dampers that can’t be reached without an access panel
- Corroded dampers in damp risers and plant rooms
Wherever there are offices above shops, near Mortlake station or elsewhere in Mortlake, ductwork may cross fire-resisting floors, and any dampers need testing.
