Fire damper testing for sites in Colliers Wood

Fire damper testing for kitchens and businesses in Colliers Wood

The idea behind drop testing is straightforward: we release the blade, watch it close fully, then reset it. We do this for buildings in Colliers Wood and across Greater London, keeping a log for each damper so there’s a history to look back on. The work covers riser dampers, motorised smoke dampers and wall and floor dampers, and people most often call us about corroded dampers in damp risers and plant rooms and fire dampers nobody can get to.

Damper testing in London buildings is usually planned around the people in them, so it’s often done out of hours or one zone at a time. We agree access to ceilings, risers and plant rooms with the building before any work starts.

Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How it works

A visit follows the same order every time: protect the area, make the system safe, carry out the fire damper testing, tidy up and hand over the paperwork. On site, the work takes a few hours for a single floor, with bigger buildings phased over more than one visit. For a job in Colliers Wood, tell us about loading bays, permits, lifts and roof access when you book.

  1. First we check the schedule and the last set of results.
  2. Each damper is found and checked for access.
  3. We test fire dampers by dropping them and smoke dampers by operating them through the controls.
  4. Dampers that pass are reset, and failures are logged with what we found.
  5. The report sets out the results, and we can quote to repair or replace failed dampers.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Name a contact who can let us in at the agreed time
  • Mention any parking or loading restrictions

Leave it or put it right?

Testing every year builds a history for each damper so repeat problems show up early. A damper that was slow last year and sticks this year tells you something before it becomes a failure. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

What affects the cost of fire damper testing

The survey tells us what the work involves. The main factors are:

  • How big the system is
  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • The times the site is available

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Asking for a quote

Photos let us diagnose from a distance. The most useful are:

  • Your opening hours and when the area is out of use
  • Detail shots of panels, filters and grilles
  • Any previous report or certificate
  • Any symptoms, from odd noises to smells or leaks

To get a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.

What the work involves, part by part

Ceiling voids and risers

Ceiling voids are where lots of dampers end up. Ceiling tiles are lifted for access and replaced afterwards.

Offices and retail

In shared buildings, some dampers sit inside tenants’ space. We agree access with the managing agent before the visit.

Between visits

Results last longer with the right care. Here’s what we suggest:

  • Get remedials done soon after a failed test
  • Keep ceiling hatches and duct panels easy to open
  • Add new dampers to the register as they’re fitted
  • Store test records alongside the fire risk assessment

If we couldn’t get to a damper, the report says so and why, for example a missing panel or a covered hatch. Access panels can be fitted so those dampers are tested on the next visit.

Good access is half the battle. Where there’s no hatch, an access panel makes testing possible before the next test.

What we’re called out for in Colliers Wood

Dust settles on damper blades, runners and springs over the years. If the duct carries cooking vapour, a film of grease adds to it, and either one can hold the blade part-open.

What we are most often called out for:

  • Damper actions from a fire risk assessment
  • Fire dampers that haven’t been tested for over a year
  • Dust or grease build-up on damper blades
  • Fire dampers nobody can get to

If you manage a historic building in the area (Southside House is about 2.8 miles west), dampers fitted during conversions can be hard to reach and need recording.

What your quote should include

  • Whether a written report and pictures are included
  • Whether inaccessible sections are listed on the report
  • If the quote is a fixed price or an estimate
  • If they look at the system before pricing

Common questions in Colliers Wood

Do you do school damper testing in Colliers Wood in the summer holidays?

Yes, holiday work suits schools best. There are about 37 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Colliers Wood. Send us your term dates when you give us a ring on 0345 646 2711 or email us, and we’ll fit the work in.

Can you come to Colliers Wood after we close?

Yes, nights and weekends are routine for us. The work in Colliers Wood can fit around your hours. Tell us your opening hours when you ask for a quote.

Will we have to shut during the visit?

Not normally. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.

How much does fire damper testing cost in Colliers Wood?

We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.

What do you need from me for a quote?

A short description and a few photos plus the address and your hours. If we need more, we’ll ask.

How long does fire damper testing take?

Typically the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. It comes down mainly to how many dampers there are and how easy they are to get to.

Can one contract cover all our sites?

Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.

Will we get a certificate for the dampers?

The record we give you is a report of the tests for every damper on the visit. Any failures come with a note of the remedials needed.

In-house cleaning or a specialist?

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. Cleaning inside ducts and units is specialist work.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
