Fire damper testing in Portsmouth, done properly
Smoke dampers work differently from fire dampers. A smoke damper is driven by a motor and responds to signals from its controls, so testing means running them through their controls and checking that each blade moves fully and returns. The work covers riser dampers, fusible link fire dampers and offices and schools, and common reasons people get in touch are dampers hidden with no access panel or hatch and dampers clogged with dust or grease.
Busy buildings in Portsmouth stay open while their dampers are tested, so the work is planned area by area, out of hours where needed.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few hours for a single floor, with bigger buildings phased over more than one visit. Where a site in Portsmouth has more than one system, we can take them one at a time to keep the rest running.
- First we check the schedule and the last set of results.
- We locate every damper and note any we can’t reach.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Before we arrive
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
Getting a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, call 0345 646 2711 or send us an email.
Advice

What fire damper testing looks like in Portsmouth
Portsmouth is within about 1 mile of the coast. Corrosion is a known cause of damper failure, and coastal air adds to the risk near intakes and louvres. Food Standards Agency records list about 48 schools, colleges and universities, about 49 care, childcare and hospital premises and about 16 hotels and B&Bs registered as food businesses in Portsmouth and the streets around it, up to about 1.5 miles out. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Hampshire and Isle of Wight Fire and Rescue Service covers Portsmouth. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up.
If you manage offices, shops or flats near Fratton station, the ductwork in them may pass through fire-resisting walls and floors, and any dampers need testing at least once a year. School buildings such as Manor Infant School are usually tested in the holidays, wherever they have dampers.
Portsmouth is in England. We carry out fire damper testing for commercial premises of every kind in Portsmouth. Our area takes in 19 places across Portsmouth, large and small.
Every address in PO6, PO4, PO1 and PO2 is within our area for fire damper testing, from busy streets to back roads.

We also cover the places around Portsmouth: Rudmore (1 mile north-west), Landport (1 mile south-west), North End (1 mile north), Fratton (1 mile south-east) and Kingston (1 mile south-east).

Not far away are Milton Locks and Portsdown Hill.
What affects the cost of fire damper testing
We don’t publish a price list, because sites vary so much. What we look at:
- Whether several sites go on one quote
- The scale of the work
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Questions from Portsmouth
Can you come to Portsmouth after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Portsmouth needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Which fire service covers Portsmouth?
That is Hampshire and Isle of Wight Fire and Rescue Service. If a fire safety officer audits the building, they may ask for the latest damper test records.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How often does BESA say fire dampers should be tested?
BESA guidance is that fire dampers are tested on completion of installation and at least annually after that. Spring-operated dampers need annual testing as a minimum.
How do you deal with dampers that cannot be reached?
We don’t leave it off the report; we note it as not reached. Once there’s a panel or a way through the ceiling, it can be tested.
Are you insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Portsmouth. Larger estates can be phased building by building around the people who use them.
How the job changes from site to site
Offices and retail
Fit-outs and tenant changes are hard on dampers. A test after the works shows the dampers still close.
Access panels
If we cannot reach a damper, it goes on the report as inaccessible. We can fit access panels so it’s tested next time.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Do you need fire damper testing in Portsmouth?
Over time, dust builds up on the blade, the runners and the spring. Where the duct carries grease or cooking vapour, grease coats them too, and either one can hold the blade part-open.
Signs it’s time to call us include:
- Blades that jam part-way when released
- Dampers clogged with dust or grease
- Rusted damper blades and springs
- Dampers overdue for their annual drop test
Royal Portsmouth Hospital, about 0.7 miles south-west of Portsmouth, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.
Comparing quotes
- What records you’ll receive afterwards
- What hours they’ll be on site
- What happens if part of the system can’t be accessed
- Whether the quote is based on a survey or photos
Why deal with it now?
Leaving damper testing for another year does not make the dampers any more likely to work. The guidance from BESA is at least once a year, and a skipped year leaves a hole in your records as well. If an insurer or inspector asks when the work was last done, an up-to-date certificate answers the question.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
