What staff can safely do

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

How we handle fire damper testing in Flamstead

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, and any that fail are listed with the reason. You end up with a clear record to keep with your fire safety documents. The work covers wall and floor dampers, motorised smoke dampers and fusible link fire dampers, and the jobs we see most are rusted damper blades and springs and smoke dampers that need testing through their controls.

In rural areas, conversions, country hotels and care homes can have ductwork crossing fire-resisting walls, and the dampers in them are easily forgotten. The first visit starts by locating each damper.

We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Common questions in Flamstead

Do you work overnight in Flamstead?

Yes, nights and weekends are routine for us. The work in Flamstead can fit around your hours. Your opening times are the first thing we ask for.

Which fire service covers Flamstead?

Fire safety enforcement in Flamstead is handled by Hertfordshire Fire and Rescue Service. If a fire safety officer audits the building, they may ask for the latest damper test records.

What’s TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

Do you offer maintenance contracts?

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

What happens to the waste?

It leaves the site with us when we go. During the work, it’s contained so the area stays clean.

What happens to dampers you cannot get to?

We do not leave it off the report; we note it as not reached. Once there’s a panel or a way through the ceiling, it can be tested.

Does the law say we must follow TR19?

Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.

What should I send you?

A short description and a few photos, with the address and opening hours. We’ll ask for anything else we need.

Landlords, agents and facilities managers

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Facilities teams in offices, schools and healthcare sites book us too in Flamstead and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.

Signs you need fire damper testing in Flamstead

Dampers are hidden above ceilings, inside risers and behind boxing. If there’s no hatch to reach them, they slip off everyone’s list, and one that cannot be reached can’t be tested.

Signs it’s time to call us include:

  • Dampers that stick or will not close fully
  • Gaps in the fire damper test log
  • Rusted damper blades and springs
  • Fire damper items raised by an assessor

If you manage a school site such as Flamstead Village School, any fire dampers can be tested in the holidays.

Before booking anyone

  • How areas they can’t reach will be recorded
  • Whether the quote shows VAT
  • What records you will receive afterwards
  • What insurance they carry

Questions to ask before booking

What the work involves, part by part

Schools, hospitals and care homes

In schools and colleges, testing fits well into holidays and weekends, with no classes to work around.

Offices and retail

Fit-outs and tenant changes are hard on dampers. Testing after a fit-out shows whether anything was disturbed.

What fire damper testing can’t fix

We’ll always give you a straight diagnosis, so here’s what this work cannot put right:

  • Missing dampers that a designer needs to specify
  • Fire alarm or control system faults behind a smoke damper
  • Deciding where dampers should be fitted

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

Parts of the system we cover

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

Keeping the system healthy

Think of this as the after-treatment advice, in brief:

  • Tell contractors where dampers are before they start work
  • Book the next test before the year runs out
  • Keep an eye out for damp around dampers
  • Update the register when ductwork changes

After testing, you get a report listing each of the fire and smoke dampers we tested, with where it is and whether it passed. Keep it with the building’s fire safety records so it’s to hand for assessors and insurers.

Keeping to at least annual testing stops small faults turning into failed dampers. Faults caught early are easier to fix.

What fire damper testing looks like in Flamstead

Hertfordshire Fire and Rescue Service covers Flamstead. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. Hemel Hempstead Hospital is the nearest hospital, about 5 miles south of Flamstead. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed.

Historic houses near Flamstead, with Childwickbury Manor about 4.6 miles south-east, are a reminder that older buildings can hold dampers in unexpected places. Healthcare buildings such as Hemel Hempstead Hospital (about 5 miles south) rely on fire compartments, and the dampers in them need testing at least annually.

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes anything from a couple of hours for a handful of dampers to a full day for a large building. In a small place like Flamstead, the journey is planned ahead and the visit arranged around the site’s hours.

  1. First we look at any damper register, drawings or earlier test reports.
  2. Each damper is located and reached through its access panel.
  3. Fire dampers are drop tested and smoke dampers are run through their controls.
  4. We reset every damper that passes and check it’s left open.
  5. You get a report listing each damper, its result and any remedials needed.

Preparing for the visit

  • Have your last certificate or report to hand
  • Move anything stored near the system
  • Mention any parking or loading restrictions
