  • Fire-stopping gaps around the duct where it passes through the wall

Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly before booking.

  • Hospitals and care homes
  • Fusible link fire dampers

Fire damper testing in Apsley

Under BESA guidance, every fire damper is tested on completion of installation and then at least once a year. For spring-operated types, annual testing is the minimum. Our job is to do the testing and hand you the paperwork that shows it. The work covers fusible link fire dampers, riser dampers and hospitals and care homes, and the jobs we see most are dampers hidden with no access panel or hatch and dampers overdue for their annual drop test.

Where there are care homes, schools or hotels around a place like Apsley, their dampers are often in the ductwork serving kitchens, plant rooms and corridors. We plan the work around the people using the building.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Common problems we fix in Apsley

Corrosion is another common cause of failure. Condensation, leaks and damp plant rooms corrode the parts that need to move, so a damper can seize without anyone noticing.

Any of these means the system needs a check-up:

  • Fire dampers that haven’t been tested for over a year
  • Dirty dampers that may not close
  • Fire dampers that fail to drop shut
  • Smoke dampers that need testing through their controls

Healthcare buildings such as Hemel Hempstead Hospital (about 0.9 miles north) rely on fire compartments, and the dampers in them need testing at least annually.

What staff can safely do

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Between visits

A little care between visits keeps the system in better shape. We recommend:

  • Update the register when ductwork changes
  • Keep ceiling hatches and duct panels easy to open
  • Report leaks or condensation near ductwork quickly
  • Diary the annual test well ahead

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

Deal with leaks and condensation near dampers quickly. Rusted parts are one of the main reasons dampers fail to close.

Fire damper testing in Apsley: local notes

Going by the FSA’s register, there are about 22 schools, colleges and universities and about 23 caring premises (care homes, nurseries and hospitals) serving food in and around Apsley, 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. The nearest hospital to Apsley is Hemel Hempstead Hospital, about 0.9 miles north. Smaller healthcare sites, from surgeries to care homes, need the same annual damper test as a hospital. Hertfordshire Fire and Rescue Service covers Apsley. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises.

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

Apsley is about 1 mile south of Hemel Hempstead, in Hertfordshire. We provide fire damper testing for businesses, landlords and public buildings in Apsley and the rest of Hertfordshire.

What we do, step by step

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. Getting to the system matters more than parking in a place like Apsley, so let us know how to reach it.

  1. We plan access and timing with you first, including any out-of-hours work.
  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. The damper is reset and its condition noted.
  5. Panels and tiles go back, and the results are written up.

Preparing for the visit

  • Tell us about site rules, permits or sign-in
  • Clear the space around the work
  • Plan for cooking equipment or plant to be off before we arrive

How to get a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

For landlords and multi-site operators

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

Apsley: your questions answered

Do you test dampers in schools in Apsley during the holidays?

Yes. Half-terms and the summer break are the natural time for school work. There are about 22 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Apsley. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Can the work in Apsley be done at night or at weekends?

Yes, nights and weekends are routine for us. That way a site in Apsley doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we will plan around them.

What happens to dampers you can’t get to?

Any damper we cannot reach is listed on the report so nothing is quietly missed. An access panel tends to solve it, and we can quote to fit one.

Do you work with multi-site operators?

Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.

Is TR19 cleaning required by law?

Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.

Are you insured?

Yes. We’re fully insured, and the details are available on request.

Do we need to close while you work?

Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.

How we price fire damper testing

Your quote is based on your site. We take into account:

  • Working hours and out-of-hours timing
  • Whether several sites go on one quote
  • The scale of the work
  • A single visit or a regular plan

The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What we need to know

To speed up the quote, please include:

  • The roof, plant room or outside wall the system runs to
  • A few general shots of the system
  • Problems your staff have spotted
  • The times we could work without disrupting the site

Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.
