Fire damper testing across New Ash Green

Fire damper testing in New Ash Green

Not every damper relies on heat. A smoke damper is driven by a motor and responds to signals from its controls, so we test them by operating them through those controls and confirming every blade travels fully and comes back. Typical jobs include blades that jam part-way when released and dampers clogged with dust or grease, across motorised smoke dampers, wall and floor dampers and offices and schools.

Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. The first visit starts by locating each damper.

Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

FAQs for New Ash Green

Can a school’s dampers in New Ash Green be tested out of term time?

Yes. The holidays are the usual time for school work. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of New Ash Green. You can ring 0345 646 2711 or send us an email with the dates the site is empty.

Can you work in New Ash Green outside opening hours?

Yes. We work evenings, overnight and at weekends. That way a site in New Ash Green doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.

Can we book visits on a schedule?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

How often should fire dampers be tested?

BESA’s guidance is a test on installation and at least once a year after that. Some sites choose to test more often where the risk is higher.

What should I send you?

The site address, the type of premises and your opening hours, along with a few pictures and any previous report.

Will we get a certificate for the 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.

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 will talk you through the next steps.

Do you work with multi-site operators?

Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.

When something else is needed

Fire damper testing cannot fix everything, and we’d rather say so up front. It doesn’t solve:

  • Ductwork crossing a fire wall with no damper fitted
  • Control wiring problems outside the damper itself
  • Designing the building’s fire compartments

If you’re not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.

Where we work

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

Do you need fire damper testing in New Ash Green?

Links and springs age like any other part. Damaged or painted links and weak springs mean the blade may stop short, and that only becomes clear during a drop test.

These are the problems we see most often:

  • Fire dampers nobody can get to
  • Blades that jam part-way when released
  • Corroded dampers in damp risers and plant rooms
  • Fire damper items raised by an assessor

If you manage a care home or clinic near New Ash Green, the testing that a hospital like Darent Valley Hospital (about 5.2 miles north-west) relies on applies to your dampers too.

Before you book anyone

  • How they set the interval to the next visit
  • Whether the quote is based on a survey or photos

How to choose an extract cleaning contractor

Staff cleaning versus specialist work

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 is our job.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

How the job changes from site to site

Fusible link fire dampers

The common fire damper uses a link that holds the blade open. When the link reaches its set temperature it melts, and the blade drops to close the duct. We release the blade, check it closes fully and reset it.

Offices and retail

Each new fit-out brings a risk of damaged or covered dampers. A test after the works shows the dampers still close.

New Ash Green buildings and fire safety

The FSA’s food hygiene register lists about 6 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in and around New Ash Green, up to about a mile and a half out. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Fire safety in New Ash Green falls to Kent Fire and Rescue Service. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers. New Ash Green’s nearest hospital, Darent Valley Hospital, is about 5.2 miles north-west. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed.

Historic buildings that have had ventilation added later can hide dampers in awkward places; Cobham College, about 4.3 miles east, is one of the historic houses in the area around New Ash Green. Site managers at schools such as New Ash Green Primary School typically find the summer break the easiest time for ceiling work like damper testing.

Fixed quotes for fire damper testing in New Ash Green

The diagnosis comes before the price. We look at:

  • Any permits to work or inductions
  • One-off work versus a regular cycle
  • Travel, parking and unloading
  • Whether several sites go on one quote

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Asking for a quote

To help us quote quickly, send us:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • The paperwork from the last visit, if you have it
  • Detail shots of panels, filters and grilles

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

The process

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes from an hour or two in a small building to several visits on a large estate. Visits to a village like New Ash Green are booked in advance, at a time that suits whoever runs the site.

  1. We go through the damper schedule and any previous faults.
  2. Each damper is found and checked for access.
  3. We test fire dampers by dropping them and smoke dampers by operating them through the controls.
  4. Dampers that pass are reset, and failures are logged with what we found.
  5. We report the results and offer remedials on failed dampers.

Before we arrive

  • Find the previous report, if there is one
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Mention any parking or loading restrictions

Getting a quote

We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.

Advice

Looking after it afterwards

Here’s the after-treatment advice, short and simple:

  • Don’t let hatches get painted shut or boarded over
  • Keep to at least yearly testing
  • Get remedials done soon after a failed test
  • Report leaks or condensation near ductwork quickly

If we couldn’t get to a damper, the report says so and why, for example a missing panel or a covered hatch. Access panels can be fitted so those dampers are tested on the next visit.

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.
