Hertfordshire · Fire damper testing
Fire damper inspection in Hertford
Fire damper testing for businesses, landlords and public buildings in Hertford. CHAS, SafeContractor and ISO 9001, and fully insured.
- Dampers that can’t be reached without an access panel
- Fire dampers that fail to drop shut
- Damper actions from a fire risk assessment
Between visits
Once we’ve finished, these simple steps help:
- Act on failed dampers rather than leaving them on file
- Store test records alongside the fire risk assessment
- Keep to at least yearly testing
- Keep an eye out for damp around dampers
Put the next test in the diary within twelve months. The guidance is at least once a year, and booking the same month each year keeps it simple.
The simplest way to avoid failures is to test on time, every year. A blade that’s just starting to stick is easier to deal with than a seized one.
How we handle fire damper testing in Hertford
Plenty of buildings have dampers nobody has looked at since they were fitted. Ceilings have gone up, access panels have been covered or lost, and the records have gone missing. We locate and test the dampers we can reach and record the ones we cannot, so you can see exactly what still needs access. If you have dampers that stick or won’t close fully and fire dampers with no recent test record, we can put it right, from motorised smoke dampers, fusible link fire dampers and hospitals and care homes onwards.
In a town like Hertford, the buildings with fire dampers tend to be schools, offices, surgeries, care homes, hotels and blocks of flats. Any building with ductwork through fire-resisting walls or floors should have its dampers tested at least annually.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Questions from Hertford
Can you work in Hertford outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Hertford needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Which fire service covers Hertford?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Hertford. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.
What does fire damper testing cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will typically reply within one working day.
Who has the duty to keep fire dampers working?
Under the Fire Safety Order 2005, it’s the responsible person, who might be the employer, owner, landlord, facilities manager or managing agent. Keeping fire safety systems working, dampers included, is part of their duty.
What happens if a damper fails its test?
The fault is recorded and explained in the report. We can then repair or replace the damper as a remedial job and test it again.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
What fire damper testing looks like in Hertford
There are about 22 schools, colleges and universities, about 12 hospitals, care homes and childcare premises and about 3 hotels and B&Bs on the FSA’s food hygiene register within about 1.5 miles of central Hertford. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Hertford sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. Hertford County Hospital is the nearest hospital, about less than half a mile south-west of Hertford. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have.
Hertford County Hospital, about less than half a mile south-west of Hertford, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests. If you manage a school site such as Mill Mead Primary School, any fire dampers can be tested in the holidays. If you manage offices, shops or flats near Hertford East station, the ductwork in them may pass through fire-resisting walls and floors, and any dampers need testing at least once a year.
Hertford is about 9 miles south-east of Stevenage, in Hertfordshire. We provide fire damper testing for businesses, landlords and public buildings in Hertford and the rest of Hertfordshire. Hertford is one of 381 towns, villages and districts in Hertfordshire we cover for fire damper testing. We also work in London, around 21 miles away.
Work in SG14 and SG13 follows the same survey, fixed quote and written report as everywhere else we cover. Whether your site is on Salisbury Square, Market Street and Parliament Square or a nearby road, we can help. Being close to the A10 and A119, Hertford is simple for us to get to at any hour. We also cover Horns Mill (1 mile south), Foxholes (1 mile east), Rush Green (2 miles east), Hertford Heath (2 miles south-east) and Little Amwell (2 miles south-east). We also work in nearby towns such as Stevenage (9 miles north-west), St Albans (11 miles west), Bishop's Stortford (11 miles north-east), Welwyn Garden City (5 miles west), Harpenden (12 miles west) and Hitchin (13 miles north-west).
Around Hertford
Typical jobs here are in premises near The Old Barge pub and Richard Hale School and the streets around them. There’s a railway station in Hertford itself: Hertford East station. A little further out are Hertford County Hospital (under half a mile south-west) and Mcmullen & Sons Brewery Museum (under half a mile south-west). Not far away are Willowmead.
Why deal with it now?
A sticking blade caught on an annual test can be a small repair. Years of corrosion and dirt can mean the whole damper needs replacing instead. Nothing in a duct, damper or fan improves by being left.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

- Out-of-hours work and a 24/7 emergency line

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. Photos taken on a phone are typically enough for us to plan a job in Hertford and give a fixed quote.
- 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.
- Dampers that pass are reset, and failures are logged with what we found.
- We report the results and offer remedials on failed dampers.
Preparing for the visit
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Managing agents and facilities teams in Hertford
Facilities teams in offices, schools and healthcare sites book us too in Hertford and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What a clean will not put right
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Control wiring problems outside the damper itself
- Holes around ductwork in fire-resisting walls
- Sign-off of the whole building’s fire safety
If in doubt, call 0345 646 2711, or email photos and we will say what we think before booking.

Part by part
Offices and retail
Offices and shops often have dampers above ceilings that are rarely opened. Testing can be done outside opening hours so the space stays open.
Schools, hospitals and care homes
Hospitals and care homes stay occupied around the clock. The sequence of testing is agreed with staff so care isn’t interrupted.
