Fire damper testing across Farnham

The process

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes anything from a couple of hours for a handful of dampers to a full day for a large building. If you can send photos, we can arrive in Farnham knowing what to expect.

  1. First we check the schedule and the last set of results.
  2. Each damper is found and checked for access.
  3. Fire dampers are drop tested, and smoke dampers are tested through their controls.
  4. Passes are reset and any failures recorded with the reason.
  5. The report sets out the results, and we can quote to repair or replace failed dampers.

Getting ready for the visit

  • Allow time for equipment near the work to be turned off and cool down
  • Name a contact who can let us in at the agreed time
  • Clear loose items from the work area

Advice

Fire damper testing for kitchens and businesses in Farnham

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. If you’re dealing with dampers that stick or won’t close fully and rusted damper blades and springs, we can put it right, from wall and floor dampers, offices and schools and hospitals and care homes onwards.

Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. The first visit starts by locating each damper.

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, with full insurance on top.

Keeping the system healthy

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

  • Fix water leaks in plant rooms and risers promptly
  • Store test records alongside the fire risk assessment
  • Tell contractors where dampers are before they start work
  • Diary the annual test well ahead

If we couldn’t get to a damper, the report says so and why, such as no access panel or a blocked hatch. Access panels can be fitted so those dampers are tested on the next visit.

Good access is half the battle. If a damper has no access panel, have one fitted before the next test.

Fire damper testing around Farnham

Food Standards Agency data includes about 3 schools, colleges and universities in Farnham 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.

What your team can do, and what needs us

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’ll take a look and send you a fixed quote.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

What we’re called out for in Farnham

Buildings in Farnham change owners, tenants and maintenance contractors over the years, and the damper records don’t always go with them. Without a register, nobody knows how many dampers there are or when they were last tested.

Keep an eye out for any of the following:

  • Motorised smoke dampers due for testing
  • Dampers that cannot be reached without an access panel
  • Blades that jam part-way when released
  • Missing or out-of-date damper records

If you manage a care home or clinic near Farnham, the testing that a hospital like Herts and Essex Hospital (about 2.8 miles south-east) relies on applies to your dampers too.

Questions to ask before you book

Honest limits

We’d rather tell you now than book work that will not help, so here are the limits:

  • Missing dampers that a designer needs to specify
  • Signing off a building’s overall fire safety
  • Fire risk assessments, which need a fire risk assessor

If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.

Where we work

  • Hospitals and care homes
  • Wall and floor dampers
  • Fusible link fire dampers
  • Offices and schools
  • Motorised smoke dampers
  • Riser dampers

Different parts, different methods

Offices and retail

In offices and retail units, dampers tend to be hidden above working areas. We can test in the evening, overnight or at weekends so the space stays open.

Smoke dampers

If a smoke damper won’t operate when signalled, it goes on the report as a failure, along with what we saw.

Farnham: your questions answered

Do you test dampers in schools in Farnham during the holidays?

Yes, out-of-term visits are normal for schools. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Farnham, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711, or email photos, and we will fit the work in.

Do you cover smaller places like Farnham?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Where does the waste go?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

How often should fire dampers be tested?

The guidance from BESA is at least annually, by a competent person. A test on completion of installation comes first.

Are you insured?

Yes. We carry full insurance and have been trading since 2009.

Who has the duty to keep fire dampers working?

The duty falls on the responsible person for the premises. That’s often the employer, owner, landlord, facilities manager or managing agent. Our part is the testing and the records that show it’s been done.

How long does fire damper testing take?

It takes a couple of hours for a few dampers, and a day or more across a big site. Access is the biggest factor, so we will confirm the time when we quote.

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.

How we price fire damper testing

Sites vary more than people expect. The main factors:

  • Travel, parking and unloading
  • Site rules, permits and inductions
  • How big the system is
  • Whether it’s a one-off visit or part of a schedule

We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or drop us a line, and we’ll talk you through it.

What to send for a quote

When you contact us, it’s useful to have:

  • A few general shots of the system
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any previous report or certificate
  • When the site is open and when it’s quiet

Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
