Fire damper testing for sites in Belsize

About our fire damper testing in Belsize

For every damper, we record where it is, whether it passed and the state it’s in. Passes are reset and left ready to work, while failures are flagged with what we found. That record belongs with the building’s fire safety paperwork. The work covers offices and schools, fusible link fire dampers and hospitals and care homes, and people most often call us about dirty dampers that may not close and smoke dampers that need testing through their controls.

Testing in a small place like Belsize is planned around the journey and access, and the test itself is the same as in any city building.

A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What fire damper testing can’t fix

Fire damper testing cannot fix everything, and we will tell you before work begins. It won’t put right:

  • Missing dampers that a designer needs to specify
  • Signing off a building’s overall fire safety
  • Fire risk assessments, which need a fire risk assessor

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

What we work on in Belsize

  • Fusible link fire dampers

How the job changes from site to site

Access panels

Over time, hatches and panels get covered up. Clear access makes the test quicker and less disruptive.

Smoke dampers

Smoke dampers are motorised and run by a control system. We test them through their controls to confirm the blade moves all the way.

How the visit works

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a morning or an afternoon for a small number of dampers, longer where there are many. Somewhere as small as Belsize, the date and timings are agreed with you well before the day.

  1. We go through the damper schedule and any previous faults.
  2. We locate every damper and note any we can’t reach.
  3. We test fire dampers by dropping them and smoke dampers by operating them through the controls.
  4. Passes are reset and any failures recorded with the reason.
  5. We report the results and offer remedials on failed dampers.

How to prepare

  • Mention any parking or loading restrictions
  • Tell us about site rules, permits or sign-in
  • Agree a time when the area can be out of use

Advice

Staff cleaning versus specialist work

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Common questions in Belsize

Is Belsize within the area you cover?

Yes, Belsize is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.

Can fire dampers in schools around Belsize be tested in the holidays?

Yes, out-of-term visits are normal for schools. Around Belsize, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or send details by email with the dates the site is empty.

Do we lose a day’s trading?

Not usually. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.

Do you certify fire dampers?

Our paperwork is a test report, not a certificate of compliance. It lists each damper, the result and any remedials needed.

Can we book visits on a schedule?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.

Can testing be done without disrupting the building?

Yes. We work evenings, overnight and weekends, so the building keeps running. Tell us the hours that suit and we’ll plan around them.

What should I send you?

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711, or email photos.

Belsize buildings and fire safety

Food Standards Agency records list about 3 schools, colleges and universities registered as food businesses in and around Belsize, up to about a mile and a half out. If any of them has ducted ventilation, its dampers need an annual drop test at least. Belsize sits within the area of Hertfordshire Fire and Rescue Service. 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. Belsize’s nearest hospital, Hemel Hempstead Hospital, is about 4 miles north. Hospitals are a good example of a building with fire dampers across many floors and departments.

Chenies Manor House, about 2 miles south-west, is one of the historic houses near Belsize, and older buildings converted to new uses often have ventilation added later. The nearest hospital, Hemel Hempstead Hospital, is about 4 miles north; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly. School buildings such as Sarratt Church of England Primary School are normally tested in the holidays, wherever they have dampers.

Belsize is about 3 miles north of Chorleywood, in Hertfordshire. Whatever kind of site you run in Belsize, fire damper testing is something we can help with.

Leave it or put it right?

After any fire, one of the first questions is what maintenance had been done. A damper test log helps show the responsible person kept on top of things, and they only exist if the testing happened. A fault that closes a site in a village like Belsize affects everyone who depends on it.

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

Why book with us

  • Every job surveyed first
  • CHAS, SafeContractor and ISO 9001
  • Photo reports with every job
  • A fixed price before any work starts

Read how cleaning jobs are priced or how to check a contractor.

Multi-site and managed buildings

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

What affects the cost of fire damper testing

Before we fix a price, we need to know a few things. We look at:

  • The number of sites or systems
  • How big the system is
  • The times the site is available
  • Travel, parking and unloading

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

What to send for a quote

To help us quote quickly, send us:

  • When the site is open and when it’s quiet
  • The postcode and the type of business
  • The roof, plant room or outside wall the system runs to
  • Close-ups of filters, grilles, hatches or access panels

Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or email us.
