Leave it or put it right?
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. It’s simpler to plan the work at Rooks Nest now than to arrange it in a hurry later.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

Fire damper testing for kitchens and businesses in Rooks Nest
Each damper we test gets a location, a result and a note of its condition. Dampers that pass are reset and left open, ready to operate, while failures are flagged with what we found. You end up with a clear record to keep with your fire safety documents. The work covers fusible link fire dampers, offices and schools and hospitals and care homes, and the jobs we see most are blades that jam part-way when released and rusted damper blades and springs.
Testing in a small place like Rooks Nest is planned around the journey and access, and every damper is drop tested, reset and recorded, the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Multi-site and managed buildings
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 on a regular cycle.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
How it works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the fire damper testing, clear away and hand over the paperwork. On site, the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. We agree a date with you, plan the drive to Rooks Nest and turn up when the site is quiet.
- We plan access and timing with you first, including any out-of-hours work.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in

Related advice
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep damper test reports with the fire safety log
- Report leaks or condensation near ductwork quickly
- Keep the damper register up to date after any building work
- Get remedials done soon after a failed test
After testing, you get a report listing each of the fire and smoke dampers we tested, with its location and its result. Keep it with the building’s fire safety records so it’s to hand for assessors and insurers.
Make sure every damper can be reached. Where there’s no hatch, an access panel makes testing possible before the next test.
When something else is needed
Before booking, it helps to know what’s not included:
- Deciding where dampers should be fitted
- Dampers that were never installed where they’re needed
- Signing off a building’s overall fire safety
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.

How we price fire damper testing
Your quote is based on your site. We consider:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- How many systems or sites are involved
- One-off work versus a regular cycle
Every site is different, 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.
What we need to know
We can often survey from pictures. Try to include:
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
Fire damper testing around Rooks Nest
The FSA’s food hygiene register lists about 23 schools, colleges and universities and about 20 hospitals, care homes and childcare premises with registered kitchens or food service within roughly a mile and a half of the centre of Rooks Nest. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. About 0.9 miles west of Rooks Nest is Lister Hospital, the nearest hospital. Smaller healthcare sites, from surgeries to care homes, need the same annual damper test as a hospital. Rooks Nest 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.
Healthcare buildings such as Lister Hospital (about 0.9 miles west) rely on fire compartments, and the dampers in them need testing at least annually. Aston Bury, about 3.7 miles south-east, is one of the historic houses near Rooks Nest, and older buildings converted to new uses often have ventilation added later. Site managers at schools such as Trotts Hill Primary and Nursery School typically find the summer break the easiest time for ceiling work like damper testing.

In-house cleaning or a specialist?
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.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.

What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call 0345 646 2711 or send us an email.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
How long does fire damper testing take?
It takes a morning or an afternoon for a small number of dampers, longer where there are many. Access is the biggest factor, and we’ll give you an idea when we quote.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
