Why deal with it now?

A damper that’s stuck open gives fire and smoke a route straight through a fire-resisting wall. The rest of the compartment can be built perfectly and still be bypassed by the duct. It’s far better to find that out on a test than in a fire. If the system at a site near Mop End fails, there may be nowhere nearby to move to.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

  • Survey first, then a fixed quote
  • Work around your opening hours, with 24/7 emergency cover
  • One contact for all your sites in London and the South East

About our fire damper testing in Mop End

For every damper, we record where it is, whether it passed and the state it’s in. Passes are reset and left ready to work, while failures are flagged with what we found. That record belongs with the building’s fire safety paperwork. If you’re dealing with dampers overdue for their annual drop test and dirty dampers that may not close, we can put it right, from riser dampers, wall and floor dampers and motorised smoke dampers onwards.

For a building in or near Mop End, the visit is planned ahead, with access agreed in advance, and every damper is drop tested, reset and recorded, the same as anywhere.

The report is your system’s health record: a dated account with photos of everything we did. 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

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

When to call us in Mop End

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 can stop the blade dropping fully.

Signs it’s time to call us include:

  • Fire dampers with no recent test record
  • Fire dampers that fail to drop shut
  • Buildings with no damper register
  • Dust or grease build-up on damper blades

If you manage an older building converted to a hotel or venue, like many historic houses in the area (Hughenden Manor is about 4.1 miles west), finding every damper is the first job.

Questions to ask before you book

  • Whether inaccessible sections are listed on the report
  • Proof of insurance
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether the quote is based on a survey or photos

What affects the quote in Mop End

The price is fixed before any work begins. It’s based on:

  • The times the site is available
  • Travel, parking and unloading
  • Site requirements such as sign-in and permits
  • One-off work versus a regular cycle

You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we will explain what it covers.

What to send for a quote

You do not need the technical terms. It helps if you can send:

  • The roof, plant room or outside wall the system runs to
  • Close-ups of filters, grilles, hatches or access panels
  • Any symptoms, from odd noises to smells or leaks
  • The paperwork from the last visit, if you have it

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or drop us a line.

Mop End buildings and fire safety

Food Standards Agency data includes about 3 schools, colleges and universities and about 4 care, childcare and hospital premises in Mop End and the streets around it, up to about 1.5 miles out. If any of them has ducted ventilation, its dampers need an annual drop test at least. About 1.9 miles east of Mop End is Amersham Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. Buckinghamshire Fire and Rescue Service covers Mop End. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up.

Hospitals such as Amersham Hospital, about 1.9 miles east, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Mop End, the same annual testing applies. For schools like Curzon Church of England Combined School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

What happens on the day

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes a few hours for a single floor, with bigger buildings phased over more than one visit. Visits to a village like Mop End are booked in advance, at a time that suits whoever runs the site.

  1. First we look at any damper register, drawings or earlier test reports.
  2. Each damper is located and reached through its access panel.
  3. We release each fire damper blade and operate smoke dampers from their controls.
  4. We reset every damper that passes and check it’s left open.
  5. The results go into a report, with failed dampers and remedials listed.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Let us know when the site is closed or quiet
  • Arrange a key holder or contact on site

Advice

Questions from Mop End

Can you come to Mop End after we close?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.

Do you do school damper testing in Mop End in the summer holidays?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Mop End. Tell us your holiday dates and we will book the visit for when the site is empty.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Can you set up regular visits?

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

Do you have a 24/7 line?

Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.

Can one contract cover all our sites?

Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.

Who has the legal duty for fire safety?

Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.

Will we get a certificate for the dampers?

We test, record and report, rather than certify dampers to a standard. It lists each damper, the result and any remedials needed.

Managing agents and facilities teams in Mop End

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

We also work for facilities teams across offices, schools and healthcare across Buckinghamshire. Larger estates can be phased building by building to keep disruption down.

When it’s something else

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • Sign-off of the whole building’s fire safety
  • Fire-stopping gaps around the duct where it passes through the wall
  • Fire risk assessments, which need a fire risk assessor

Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
