Fire damper testing in Wandsworth

What fire damper testing can’t fix

We will always give you a straight diagnosis, so here’s what fire damper testing won’t do:

  • Gaps in the wall or floor around the damper
  • Approving the building’s fire strategy
  • Dampers that were never installed where they’re needed

About our fire damper testing in Wandsworth

Not every damper relies on heat. Smoke dampers are motorised and are opened and closed by a control system, so testing means running them through their controls and checking that each blade moves fully and returns. We’re often asked to deal with fire dampers that haven’t been tested for over a year and rusted damper blades and springs, on fusible link fire dampers, motorised smoke dampers and wall and floor dampers.

In a London area like Wandsworth, testing has to fit around tenants, residents, guests or patients, so it’s often done out of hours or one zone at a time. Access to ceiling voids and risers is agreed with the building manager first.

Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What your team can do, and what needs us

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

How the job changes from site to site

Ceiling voids and risers

Plant rooms and risers can be damp, which leads to corrosion. Signs of corrosion or water are recorded so it can be dealt with.

Fusible link fire dampers

The common fire damper uses a link that holds the blade open. When the link reaches its set temperature it melts, and the blade drops to close the duct. Testing means dropping the blade, checking the full close and resetting it.

Between visits

Here’s the after-treatment advice, short and simple:

  • Keep ceiling hatches and duct panels easy to open
  • Report leaks or condensation near ductwork quickly
  • Store test records alongside the fire risk assessment
  • Tell contractors where dampers are before they start work

After testing, you get a report listing each of the fire and smoke dampers we tested, with where it is and whether it passed. Keep it with the building’s fire safety records so it’s ready when your assessor or insurer asks.

Where a damper sits in ductwork that collects dust or grease, keeping that ductwork clean helps. It makes sense to plan duct cleaning and damper testing together.

FAQs for Wandsworth

Do you work at weekends in Wandsworth?

Yes. We work evenings, overnight and at weekends. It means the site in Wandsworth keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

Which fire authority looks after Wandsworth?

Wandsworth is in the area of London Fire Brigade. BESA guidance is that every fire damper is tested at least once a year, so an officer or insurer may expect a report less than a year old.

Can you set up regular visits?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

Do you certify fire dampers?

You get a test report recording every damper we tested, showing where it is, whether it passed and what we found. Keep it with your fire safety records.

How much does fire damper testing cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.

Where does the waste go?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.

What if a fire damper will not close?

It’s listed on the report as a fault and we quote for remedials. Once fixed, the damper is drop tested again and the record updated.

Will we have to shut during the visit?

Typically not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.

What affects the cost of fire damper testing

Your quote is based on your site. We consider:

  • How many systems or sites are involved
  • What state the system is in
  • Parking and loading at the site
  • When the work can happen, such as evenings, overnight or weekends

You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

What we need to know

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Any access panels or hatches you can see
  • Any symptoms, from odd noises to smells or leaks
  • The paperwork from the last visit, if you have it
  • Where the site is and what kind of site it is

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

How the visit works

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a few dampers, and a day or more across a big site. Getting kit into a London building takes planning, so let us know where we can load and park in Wandsworth.

  1. First we look at any damper register, drawings or earlier test reports.
  2. Dampers are located one by one and reached through their access panels.
  3. Every fire damper is dropped, and every smoke damper is tested through its controls.
  4. We reset every damper that passes and check it’s left open.
  5. We report on every damper, with faults and suggested remedials set out.

Getting ready for the visit

  • Have your last certificate or report to hand
  • Tell us where we can park and unload
  • Clear the space around the work

How to get a quote

Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What we’re called out for in Wandsworth

Over the life of a building, owners, tenants and contractors come and go, and damper records often get lost along the way. Without a register, nobody knows how many dampers there are or when they were last tested.

Any of these means the system needs a check-up:

  • Smoke dampers with no recent test
  • Fire dampers that fail to drop shut
  • Dirty dampers that may not close
  • Dampers flagged on a fire risk assessment

Wherever there are offices above shops, near Wandsworth Town station or elsewhere in Wandsworth, ductwork may cross fire-resisting floors, and any dampers need testing.

What your quote should include

  • Proof of insurance
  • Whether the quote is based on a survey or photos
  • Whether the whole system is included, or only the parts that are easy to reach
  • When they can work, and whether that’s outside your opening hours

Fire damper testing in Wandsworth: local notes

There are about 33 schools, colleges and universities, about 72 hospitals, care homes and childcare premises and about 9 hotels and B&Bs on the FSA’s food hygiene register within 1.5 miles or so of the middle of Wandsworth. 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. Wandsworth sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty. Wandsworth’s nearest hospital, Royal Hospital for Neuro-disability, is about 1 mile west. Hospitals are a good example of a building with fire dampers across many floors and departments.

Site managers at schools such as St Anne's CofE Primary School normally find the summer break the easiest time for ceiling work like damper testing. Royal Hospital for Neuro-disability, about 1 mile west of Wandsworth, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.
