Fire damper testing near Bishop's Stortford

How we handle fire damper testing in Bishop's Stortford

A drop test is simple in principle: the blade is released, checked for a full close and reset. We do this for buildings in Bishop's Stortford and across Hertfordshire, keeping a log for each damper so there’s a history to look back on. If you have fire dampers that fail to drop shut and gaps in the fire damper test log, we can help, from offices and schools, riser dampers and motorised smoke dampers onwards.

Smaller commercial buildings in towns like Bishop's Stortford may have just a handful of fire dampers, but each one can seize if it’s never tested. Dust, grease and corrosion are the usual reasons a blade will not drop.

Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

If any of them has ducted ventilation, its dampers need an annual drop test at least. Bishop's Stortford’s nearest hospital, Herts and Essex Hospital, is about 0.8 miles east. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed. Hertfordshire Fire and Rescue Service covers Bishop's Stortford. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.

Healthcare buildings such as Herts and Essex Hospital (about 0.8 miles east) rely on fire compartments, and the dampers in them need testing at least annually.

When it’s something else

We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:

  • Sign-off of the whole building’s fire safety
  • Faults in the alarm or building controls that signal smoke dampers
  • Fire risk assessments, which need a fire risk assessor

If you’re not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.

What the work covers

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

How we price fire damper testing

You’ll get a fixed price before we start. It takes into account:

  • The condition we find in the survey
  • How big the system is
  • Whether it’s a one-off visit or part of a schedule
  • Access, including roofs, risers and ceiling voids

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.

What we need to know

When you contact us, these details help:

  • Problems your staff have spotted
  • Any access panels or hatches you can see
  • The site address and the type of premises
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

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

In-house cleaning or a specialist?

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

How the visit works

A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. The visit itself takes a morning or an afternoon for a small number of dampers, longer where there are many. Send us pictures of the system and we can plan most of a visit in Bishop's Stortford before we arrive.

  1. Before the visit, we agree access, timings and any areas with restrictions.
  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. Panels and tiles go back, and the results are written up.

Preparing for the visit

  • Mention any sign-in, permit or induction we need
  • Make sure someone can let us in and lock up afterwards
  • Find the previous report, if there is one

Ask for a quote

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.

Managing agents and facilities teams in Bishop's Stortford

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

Leave it or put it right?

Until a damper has been dropped, you can’t say whether it works. A test gives you a clear answer, and we can offer remedials for any that fail, and that is something you can plan around. Whatever the system, dirt and wear only get worse.

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

  • Accredited under CHAS and SafeContractor, with ISO 9001
  • Full insurance on every job

Bishop's Stortford questions

Who enforces fire safety at workplaces in Bishop's Stortford?

Fire safety enforcement in Bishop's Stortford is handled by Hertfordshire Fire and Rescue Service. BESA guidance is that every fire damper is tested at least once a year, so an officer or insurer may expect a report less than a year old.

Do you work at weekends in Bishop's Stortford?

Yes, we can come after you close and finish before you open. That way a site in Bishop's Stortford does not have to lose a day’s trading. Just phone us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.

Are you accredited?

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

How do you protect the area?

By covering it before any work starts. We keep the work contained and clean down when we finish.

What does fire damper testing cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.

Do you work in Bishop's Stortford?

Yes. We cover Bishop's Stortford and the rest of Hertfordshire, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711, or email photos.

Who is responsible for fire safety on the premises?

The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you are not sure, check your lease and fire risk assessment.

Is TR19 a legal requirement?

No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.

What the work involves, part by part

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.

Fusible link fire dampers

A damaged or painted link can stop a damper doing its job. Each link is looked at as part of the test and any problems go on the report.
