Aftercare tips

Once we have finished, these simple steps help:

  • Tell contractors where dampers are before they start work
  • Book the next test before the year runs out
  • Fix water leaks in plant rooms and risers promptly
  • Never wedge or tie a damper open

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.

A simple register of every damper helps a great deal: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.

How we handle fire damper testing in Chesham Bois

A drop test is simple in principle: we release the blade, watch it close fully, then reset it. We do this for buildings in Chesham Bois and across Buckinghamshire, logging each one so the record builds year on year. If you are dealing with motorised smoke dampers due for testing and dirty dampers that may not close, we can help, from riser dampers, hospitals and care homes and wall and floor dampers onwards.

A building in a smaller place like Chesham Bois might have only a few dampers, and each still needs an annual drop test at least, with a record of every result.

Insurers, fire officers and environmental health officers all look at records. That is 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.

How we price fire damper testing

There’s no set price list, because no two systems are the same. The quote depends on:

  • One-off work versus a regular cycle
  • Where the site is and how we reach it
  • How many systems or sites are involved
  • How easy every part is to reach

The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.

What we need to know

What to send for a quote:

  • Any previous report or certificate
  • Wide pictures of the system and the area around it
  • Any symptoms, from odd noises to smells or leaks
  • How we’d reach plant on a roof or in a plant room

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 any work starts.

FAQs for Chesham Bois

Will you come out to Chesham Bois?

Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.

Do you test dampers in schools in Chesham Bois during the holidays?

Yes. The holidays are the usual time for school work. The FSA’s register shows about 16 schools and colleges with food registrations within roughly a mile and a half of Chesham Bois. You can phone us on 0345 646 2711, or email photos with the dates the site is empty.

Can you fix fire dampers that fail?

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 test it again afterwards.

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.

Will we get a certificate for the dampers?

What you receive is a written report of each test for every damper on the visit. Failures are set out with the remedials we’d suggest.

Which accreditations do you hold?

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Can you quote from pictures?

Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

Do you test dampers in the evening or at weekends?

Yes. We can test in the evening, overnight or at the weekend, which helps where ceilings cannot be opened during the day. Hospitals and care homes are planned with the site team.

What happens if it’s left?

A damper that’s stuck open gives fire and smoke a route straight through a fire-resisting wall. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. Even a site near Chesham Bois that’s only busy part of the week needs its system checked on a schedule.

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or email us, and we’ll explain what it covers.

Common problems we fix in Chesham Bois

Other trades work around dampers all the time. Cables get run through them, links get knocked and blades get wedged open, and any of those can stop a damper closing.

It’s time to book a visit if you see:

  • Dampers clogged with dust or grease
  • Fire dampers nobody can get to
  • Smoke dampers with no recent test
  • Blades that jam part-way when released

For managed buildings around Amersham station, damper testing can be booked out of hours so tenants aren’t disturbed.

Fire damper testing in Chesham Bois: local notes

Going by the FSA’s register, there are about 16 schools, colleges and universities and about 18 caring premises (care homes, nurseries and hospitals) serving food within roughly a mile and a half of the centre of Chesham Bois. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Fire safety in Chesham Bois falls to Buckinghamshire Fire and Rescue Service. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. About 1.7 miles south-west of Chesham Bois is Amersham Hospital, the nearest hospital. Where patients or residents may need help to leave a building, working dampers matter all the more.

Healthcare buildings such as Amersham Hospital (about 1.7 miles south-west) rely on fire compartments, and the dampers in them need testing at least annually. A school like Elangeni School can have any dampers tested over half-term without disturbing lessons.

Honest limits

A few issues sit outside what this work can do:

  • Dampers that were never installed where they’re needed
  • Fire risk assessments, which need a fire risk assessor
  • Control wiring problems outside the damper itself

If in doubt, ring 0345 646 2711, or email photos and we will say what we think before booking.

Parts of the system we cover

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

For landlords and multi-site operators

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

What we do, step by step

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a couple of hours for a few dampers, and a day or more across a big site. Tell us about any gates, ladders or locked plant areas at your site near Chesham Bois when you book.

  1. Before the visit, we agree access, timings and any areas with restrictions.
  2. We open up ceilings and hatches and take off each access panel.
  3. The blade is released and watched to make sure it closes fully.
  4. We reset it and record any dirt, corrosion or damage.
  5. We close everything up and send the results in a report.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Arrange a key holder or contact on site
  • Find the previous report, if there is one
