About our fire damper testing in Graveley
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 checking that each blade moves fully and returns. The work covers offices and schools, hospitals and care homes and fusible link fire dampers, and common reasons people get in touch are dampers clogged with dust or grease and dampers flagged on a fire risk assessment.
Testing in a small place like Graveley is planned around the journey and access, and every damper is drop tested, reset and recorded, the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Fire dampers in Graveley buildings
There are about 8 schools, colleges and universities and about 7 care, childcare and hospital premises on the FSA’s food hygiene register in and around Graveley, up to about a mile and a half out. Buildings like these often have ducted ventilation, and wherever a duct crosses a fire-resisting wall or floor there should be a damper, tested at least once a year. About 0.8 miles south of Graveley is Lister Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed. Graveley 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.
The nearest hospital, Lister Hospital, is about 0.8 miles south; healthcare buildings like it are a reminder that dampers protect people who cannot move quickly. A school like Graveley Primary School can have any dampers tested over half-term without disturbing lessons.

What else we do in Graveley
Different parts, different methods
Offices and retail
Each new fit-out brings a risk of damaged or covered dampers. Testing after a fit-out shows whether anything was disturbed.
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. Heat melts the link and the blade falls shut across the duct. We release the blade, check it closes fully and reset it.
What affects the quote in Graveley
There’s no set price list, because sites vary so much. What we look at:
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- Where the site is and how we reach it
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
For fire damper testing in Graveley, call us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We typically send a fixed quote within one working day.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to 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. Leave those to us.
When to call us in Graveley
Fusible links and springs do not last for ever. A link can be damaged, painted over or swapped for the wrong one, and a tired spring may not drive the blade home, which only shows up when the damper is dropped.
Any of these means the system needs a check-up:
- Smoke dampers that need testing through their controls
- Gaps in the fire damper test log
- Dampers clogged with dust or grease
- Dampers that stick or will not close fully
Historic buildings that have had ventilation added later can hide dampers in awkward places; Knebworth House, about 4.4 miles south, is one of the historic houses in the area around Graveley.

- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Diary the annual test well ahead
- Report leaks or condensation near ductwork quickly
- Keep ceiling hatches and duct panels easy to open
- Close off damper faults promptly
When we finish, we send a report covering every damper on the visit, with its location and its result. File it with your fire safety log so it’s ready when your assessor or insurer asks.
A simple register of every damper helps a great deal: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.
Why it’s worth doing now in Graveley
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 is something you can plan around. Systems in rural buildings are often out of sight and out of mind.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
Why choose Duct Doctor in Graveley
- A written report with pictures after each visit
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- One number for every site across the South East and London

What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. Seeing the system in photos first means the trip to Graveley can be planned properly.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Clear loose items from the work area

It’s Hertfordshire Fire and Rescue Service, which covers Graveley. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
How often does BESA say fire dampers should be tested?
The guidance from BESA is at least annually, by a competent person. Dampers should also be tested when they’re first installed.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.

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’re not sure, check your lease and fire risk assessment.
What if a damper has no access panel?
We do not leave it off the report; we note it as not reached. With an access panel fitted, it can be tested on a return visit.
