Fire damper testing for sites in Bow

Fire damper testing in Bow

Some dampers haven’t been tested since the day they went in. Ceilings get lowered, hatches get boarded over and paperwork goes astray. We find what we can, test what we can reach and list anything we cannot get to, so you know where the gaps are. If you have corroded dampers in damp risers and plant rooms and buildings with no damper register, we can help, from riser dampers, hospitals and care homes and fusible link fire dampers onwards.

Plenty of London buildings have been refitted more than once, and dampers are often left behind new ceilings with no way to reach them. In Bow, as across London, finding every damper and recording its access is part of the job.

We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When something else is needed

We will always give you a straight diagnosis, so here’s what this work can’t put right:

  • Holes around ductwork in fire-resisting walls
  • Fire alarm or control system faults behind a smoke damper
  • Signing off a building’s overall fire safety

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly.

Where we work

  • Motorised smoke dampers
  • Hospitals and care homes
  • Offices and schools
  • Fusible link fire dampers
  • Riser dampers
  • Wall and floor dampers

What your team can do, and what needs us

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

FAQs for Bow

Who is the fire and rescue service for Bow?

Bow is in the area of London Fire Brigade. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.

How do you handle parking and loading in Bow?

A loading bay, a visitor permit or off-street space near the site in Bow makes the visit easier to plan. Much of our London work is done overnight, which helps.

Do you certify fire dampers?

Our paperwork is a test report, not a certificate of compliance. It lists each damper, the result and any remedials needed.

What happens to dampers you cannot get to?

We record it as not tested and explain why. Access panels can be installed so it’s tested on the next visit.

Do you work in Bow?

Yes. Bow is part of the area we cover, as part of our area across London and the South East.

What if a fire damper won’t close?

We record the damper as failed, with the reason, whether that’s a stuck blade, rust or a damaged link. We offer remedials to repair or replace it, and it’s tested again once the work is done.

Can you test motorised smoke dampers?

Yes. Smoke dampers are motorised, so we test them by operating them through their controls. Each one is checked for full travel and the result recorded.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

Managing agents and facilities teams in Bow

For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

Aftercare tips

Aftercare is simple, and it makes the next visit easier:

  • Brief other trades about dampers in ceilings and risers
  • Add new dampers to the register as they’re fitted
  • Do not let anything obstruct a damper’s blade
  • Diary the annual test well ahead

After testing, you get a report listing each of the fire and smoke dampers we tested, with where it is and whether it passed. File it with your fire safety log so it’s ready when your assessor or insurer asks.

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.

What we do, step by step

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a few hours for a single floor, with bigger buildings phased over more than one visit. Before any visit in Bow, we agree where the van can stop and how equipment reaches the system.

  1. Before the visit, we agree access, timings and any areas with restrictions.
  2. Ceiling tiles and hatches are opened and each damper’s access panel removed.
  3. We release each blade and check it shuts all the way.
  4. We reset it and record any dirt, corrosion or damage.
  5. We close everything up and send the results in a report.

Before we arrive

  • Let us know when the site is closed or quiet
  • Dig out any earlier paperwork for the system
  • Let us know about parking and loading

Part by part

Ceiling voids and risers

Damp plant areas are hard on dampers. Signs of corrosion or water are recorded so it can be dealt with.

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.

Bow buildings and fire safety

There are about 65 schools, colleges and universities, about 45 caring premises (care homes, nurseries and hospitals) and about 17 hotels, B&Bs and guest houses on the FSA’s food hygiene register within 1.5 miles or so of the middle of Bow. Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. Bow sits within the area of London Fire Brigade. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. Managed London buildings typically need damper testing booked through the agent, often out of hours.

Wherever there are offices above shops, near Hackney Wick station or elsewhere in Bow, ductwork may cross fire-resisting floors, and any dampers need testing. School buildings such as Old Ford Primary - A Paradigm Academy are usually tested in the holidays, wherever they have dampers. If you manage a historic building in the area (Sutton House is about 1.6 miles north-west), dampers fitted during conversions can be hard to reach and need recording.
