Holwellbury fire damper testing
We cover Holwellbury for fire damper testing. Fixed quotes, work around your opening hours and photo reports as standard.
- Dust or grease build-up on damper blades
- Dampers overdue for their annual drop test
- Dampers hidden with no access panel or hatch
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a few hours for a single floor, with bigger buildings phased over more than one visit. We agree a date with you, plan the drive to Holwellbury and turn up when the site is quiet.
- First we check the schedule and the last set of results.
- We locate every damper and note any we can’t reach.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Dampers that pass are reset, and failures are logged with what we found.
- The report sets out the results, and we can quote to repair or replace failed dampers.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or send us an email.

Fire damper testing in Holwellbury
Not every damper relies on heat. A smoke damper is driven by a motor and responds to signals from its controls, so we test them by operating them through those controls and confirming every blade travels fully and comes back. If you’re dealing with blades that jam part-way when released and motorised smoke dampers due for testing, we can put it right, from wall and floor dampers, hospitals and care homes and riser dampers onwards.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. A first test normally starts with finding them all.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What your team can do, and what needs us
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.

How we price fire damper testing
The survey tells us what the work involves. The main factors are:
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
- One-off work versus a regular cycle
- Whether several sites go on one quote
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
Helping us quote
When you contact us, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
To get a fixed quote, phone us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.
Common problems we fix in Holwellbury
Building work often happens right next to dampers. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
Any of these means the system needs a check-up:
- Dampers overdue for their annual drop test
- Blades that jam part-way when released
- Fire dampers nobody can get to
- Gaps in the fire damper test log
For schools like Derwent Lower School, damper testing is easiest in the holidays, when corridors and ceilings are clear.
Before you book anyone
- Exactly which parts of the system are covered
- What paperwork you get at the end
- Whether they recommend a next date
- When they can work, and whether that is outside your opening hours

Holwellbury: your questions answered
Which fire and rescue service is responsible for Holwellbury?
It’s Hertfordshire Fire and Rescue Service, which covers Holwellbury. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Can the work in Holwellbury be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Holwellbury needn’t be disturbed. Just phone us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you cover Holwellbury?
Yes. We work in Holwellbury and the rest of Hertfordshire, as part of our work across South East England and London. To book, call us on 0345 646 2711, or email photos.
What fire damper testing cannot fix
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Fire-stopping gaps around the duct where it passes through the wall
- Control wiring problems outside the damper itself
- Approving the building’s fire strategy
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before you book.
