Fire damper testing in Great Amwell

Fire damper testing in Great Amwell

The idea behind drop testing is straightforward: the blade is released, checked for a full close and reset. We do this for buildings in Great Amwell and across Hertfordshire, logging each one so the record builds year on year. If you are dealing with damper actions from a fire risk assessment and dampers hidden with no access panel or hatch, we can help.

For a building in or near Great Amwell, the visit is planned ahead, with access agreed in advance, and every damper is drop tested, reset and recorded, the same as anywhere.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

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

How it works

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a morning or an afternoon for a small number of dampers, longer where there are many. The timing of a visit to Great Amwell is set by you, and the travel is our side of the planning.

  1. First we look at any damper register, drawings or earlier test reports.
  2. We find every damper and open it up through the access panel.
  3. Every fire damper is dropped, and every smoke damper is tested through its 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.

Before we arrive

  • Have your last certificate or report to hand
  • Mention any sign-in, permit or induction we need
  • Clear the space around the work

Getting a quote

Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Questions from Great Amwell

Which fire and rescue service is responsible for Great Amwell?

Can you work in Great Amwell outside opening hours?

Will we get a certificate for the dampers?

The record we give you is a report of the tests, damper by damper. Failures are set out with the remedials we’d suggest.

Do you carry out smoke damper testing?

Yes, as well as drop testing fire dampers. Smoke and fire dampers are reported together, so you have one record.

Do we lose a day’s trading?

Normally not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages so parts stay in use.

Do you cover Great Amwell?

Is there a survey before the work?

Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.

How we price fire damper testing

We don’t publish a price list, because sites vary so much. The quote depends on:

  • Site rules, permits and inductions
  • Where the site is and how we reach it
  • How many systems or sites are involved
  • The condition of the system

Kitchens, offices, schools and hospitals are all priced 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.

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • Your opening hours and when the area is out of use
  • Close-ups of filters, grilles, hatches or access panels
  • Wide photos of the system and the area around it
  • The paperwork from the last visit, if you have it

To get a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

What fire damper testing cannot fix

We won’t sell you work that doesn’t address the problem, so here are the limits:

  • Holes around ductwork in fire-resisting walls
  • Fire alarm or control system faults behind a smoke damper
  • Dampers that were never installed where they’re needed

Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

Parts of the system we cover

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

Why deal with it now?

Testing every year builds a history for each damper, which shows patterns early. If the same damper keeps giving trouble, the record shows it long before it fails outright. With notice, the visit to Great Amwell can be fitted around your bookings and events.

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

How the job changes from site to site

Fusible link fire dampers

Spring-operated fire dampers need testing at least once a year. A weak spring or a sticking blade shows up when the damper is dropped.

Access panels

A damper can only be tested if it can be reached. Most need an access panel in the duct and a hatch in the ceiling or wall.
