Fire damper testing across Sevenoaks

Common problems we fix in Sevenoaks

Over the life of a building, owners, tenants and contractors come and go, and the damper records don’t always go with them. With no register, it’s hard to say how many dampers exist, let alone when they were tested.

Look out for any of the following:

  • Corroded dampers in damp risers and plant rooms
  • Missing or out-of-date damper records
  • Damper actions from a fire risk assessment
  • Dampers hidden with no access panel or hatch

If you manage an older building converted to a hotel or venue, like many historic houses in the area (Knole House is about 1.3 miles south-east), finding every damper is the first job.

Choosing a duct cleaning contractor

How we handle fire damper testing in Sevenoaks

Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. Most are held open by a fusible link that melts at a set temperature, letting the blade drop and close the duct. A drop test shows that the damper still does that when it matters, and we record the result for every damper we test. We are often asked to deal with missing or out-of-date damper records and dampers clogged with dust or grease, across motorised smoke dampers, offices and schools and wall and floor dampers.

Smaller commercial buildings in towns like Sevenoaks may have just a handful of fire dampers, but each one can seize if it’s never tested. Dust, grease and corrosion are the usual reasons a blade will not drop.

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Common questions in Sevenoaks

Can a school’s dampers in Sevenoaks be tested out of term time?

Yes, and it’s the easiest time to do it. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Sevenoaks. Just call us on 0345 646 2711 or email us with your term dates and we’ll plan around them.

Do you work at weekends in Sevenoaks?

Yes, we can come after you close and finish before you open. It means the site in Sevenoaks keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.

What if a fire damper won’t close?

We note the failure and what we found. A repair or a replacement can follow as a remedial job with a fresh test at the end.

What happens if you cannot reach some of it?

The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.

Do you survey before quoting?

Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.

How much does fire damper testing cost in Sevenoaks?

Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.

Can you come out in an emergency?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.

What should I send you?

The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.

Between visits

Here’s the after-treatment advice, in brief:

  • Book the next test before the year runs out
  • Keep damper test reports with the fire safety log
  • Keep cables and fixings away from damper blades
  • Fix water leaks in plant rooms and risers promptly

If we couldn’t get to a damper, the report says so and why, such as no access panel or a blocked hatch. Access panels can be fitted so those dampers are tested on the next visit.

Where a damper sits in ductwork that collects dust or grease, keeping that ductwork clean helps. It makes sense to plan duct cleaning and damper testing together.

Landlords, agents and facilities managers

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

What happens on the day

Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a few hours for a single floor, with bigger buildings phased over more than one visit. In Sevenoaks, the visit is planned around your opening hours, parking and access to the system.

  1. We start with whatever records exist: registers, drawings or old reports.
  2. Dampers are located one by one and reached through their access panels.
  3. We release each fire damper blade and operate smoke dampers from their controls.
  4. Each one that passes is reset, ready to work.
  5. You get a report listing each damper, its result and any remedials needed.

How to prepare

  • Clear the space around the work
  • Name a contact who can let us in at the agreed time
  • Mention any locked doors, roof access or ceiling voids

Staff cleaning versus specialist work

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.

What affects the quote in Sevenoaks

You’ll get a fixed price before any work starts. It takes into account:

  • Site rules, permits and inductions
  • The condition of the system
  • Where the site is and how we reach it
  • Working hours and out-of-hours timing

We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

What to send for a quote

To speed up the quote, send us:

  • How we’d reach plant on a roof or in a plant room
  • The paperwork from the last visit, if you have it
  • Wide photos of the system and the area around it
  • The site address and the type of premises

For a fixed quote, call us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Leave it or put it right?

Until a damper has been dropped, you cannot say whether it works. A test gives you a clear answer, and we can offer remedials for any that fail, which is far easier to plan for. A small fault found now is a quick job; the same fault found later can close the site.

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Why us?

  • Out-of-hours work and a 24/7 emergency line
  • A fixed price before any work starts
  • We diagnose before we treat
  • One contact for all your sites in London and the South East

What fire damper testing looks like in Sevenoaks

Food Standards Agency records list about 18 schools, colleges and universities, about 12 hospitals, care homes and childcare premises and about 3 hotels, B&Bs and guest houses registered as food businesses across Sevenoaks 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. About 0.6 miles north-east of Sevenoaks is Sevenoaks Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. Sevenoaks is covered by Kent Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.

If you manage a school site such as Sevenoaks Primary School, any fire dampers can be tested in the holidays. Wherever there are offices above shops, near Sevenoaks station or elsewhere in Sevenoaks, ductwork may cross fire-resisting floors, and any dampers need testing.
