Fire damper testing in Blackstone

Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. Drop testing proves that this still happens, and every result is written down, damper by damper. If you have buildings with no damper register and dampers clogged with dust or grease, we can put it right.

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

For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Leave it or put it right?

An untested damper is an unknown. Testing turns it into a known pass or a known fault, with remedials offered for anything that fails, and that’s something you can plan around. Rural sites can’t always move to another kitchen or room when something fails.

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.

Common questions in Blackstone

Do you work in villages like Blackstone?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Can you work in Blackstone outside opening hours?

Yes, nights and weekends are routine for us. That way a site in Blackstone doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.

Are you accredited?

We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What does fire damper testing cost?

It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711 or send us an email with the site type, opening hours and a few pictures.

How much notice do you need?

For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.

Can you look after several sites?

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.

How do you deal with dampers that cannot be reached?

We record it as not tested and explain why. We can fit an access panel so it’s tested on the next visit.

What is TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

Different parts, different methods

Offices and retail

Multi-let buildings may have dampers inside tenant areas. Access to each area is planned with whoever manages the building.

Fusible link fire dampers

Most fire dampers are held open by a fusible link. Heat melts the link and the blade falls shut across the duct. We release the blade, check it closes fully and reset it.

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

What happens on the day

On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes from an hour or two in a small building to several visits on a large estate. Rural roads and tight entrances are worth telling us about before a visit to Blackstone.

  1. We plan access and timing with you first, including any out-of-hours work.
  2. We open up ceilings and hatches and take off each access panel.
  3. We release each blade and check it shuts all the way.
  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

  • Tell us about site rules, permits or sign-in
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Arrange a key holder or contact on site

When to call us in Blackstone

Over the life of a building, owners, tenants and contractors come and go, and damper records often get lost along the way. With no register, it’s hard to say how many dampers exist, let alone when they were tested.

Keep an eye out for these warning signs:

  • Dust or grease build-up on damper blades
  • Dampers affected by leaks or condensation
  • Dampers that can’t be reached without an access panel
  • Gaps in the fire damper test log

Drop testing in and around Blackstone means releasing each blade, watching it close and resetting it.

What your quote should include

  • Whether the quote shows VAT
  • Proof of accreditation you can verify
  • Proof of insurance
  • What paperwork you get at the end

Choosing a duct cleaning contractor

What affects the cost of fire damper testing

The price is fixed before any work begins. It takes into account:

  • Working hours and out-of-hours timing
  • One-off work versus a regular cycle
  • Parking and loading at the site
  • How big the system is

You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

What we need to know

To speed up the quote, send us:

  • A few general shots of the system
  • How we’d reach plant on a roof or in a plant room
  • Your opening hours and when the area is out of use
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.

Staff cleaning versus specialist work

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
