What a clean will not put right

To be straight with you, there are a few things this work won’t fix:

  • Fire alarm or control system faults behind a smoke damper
  • Ductwork crossing a fire wall with no damper fitted
  • Signing off a building’s overall fire safety

If you’re not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.

What we work on in Loudwater

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

Fire damper testing in Loudwater, done properly

Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. Drop testing proves that this still happens, and we record the result for every damper we test. The work covers riser dampers, fusible link fire dampers and offices and schools, and the jobs we see most are fire dampers nobody can get to and dirty dampers that may not close.

For a building in or near Loudwater, the visit is planned ahead, with access agreed in advance, and the test itself is the same as in any city building.

It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits

Once we have finished, these simple steps help:

  • Keep ceiling hatches and duct panels easy to open
  • Keep an eye out for damp around dampers
  • Keep the damper register up to date after any building work
  • Close off damper faults promptly

Dampers we couldn’t reach are listed with the reason, such as no access panel or a blocked hatch. We can fit access panels so they can be tested next time.

The simplest way to avoid failures is to test on time, every year. Faults caught early are easier to fix.

What affects the cost of fire damper testing

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

  • How many systems or sites are involved
  • One-off work versus a regular cycle
  • What state the system is in
  • How easy every part is to reach

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

What we need to know

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • Wide photos of the system and the area around it
  • Any access panels or hatches you can see
  • The roof, plant room or outside wall the system runs to
  • The postcode and the type of business

To get a fixed quote, phone us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

What your team can do, and what needs us

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

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.

Fire dampers in Loudwater buildings

The FSA’s food hygiene register lists about 20 schools, colleges and universities, about 11 hospitals, care homes and childcare premises and about 3 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Loudwater. 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. Fire safety in Loudwater falls to Hertfordshire Fire and Rescue Service. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. About 3.2 miles south-east of Loudwater is Bishops Wood Hospital, the nearest hospital. Smaller healthcare sites, from surgeries to care homes, need the same annual damper test as a hospital.

If you manage a care home or clinic near Loudwater, the testing that a hospital like Bishops Wood Hospital (about 3.2 miles south-east) relies on applies to your dampers too. Chenies Manor House, about 2.5 miles north-west, is one of the historic houses near Loudwater, and older buildings converted to new uses often have ventilation added later.

Common questions in Loudwater

Who enforces fire safety at workplaces in Loudwater?

That’s Hertfordshire Fire and Rescue Service. If a fire safety officer audits the building, they may ask for the latest damper test records.

Can you come to Loudwater after we close?

Yes, nights and weekends are routine for us. The site is handed back ready to open. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.

Can you fix fire dampers that fail?

The failure goes on the report, along with what caused it, such as a sticking blade, corrosion or a damaged link. We offer remedials to repair or replace it, and test it again afterwards.

Do we need to close while you work?

Not normally. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.

What types of premises do you cover?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

How long will damper testing take?

It takes anything from a couple of hours for a handful of dampers to a full day for a large building. How easily we can reach the dampers makes the most difference, so we’ll confirm the time when we quote.

What do you do to protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

Signs you need fire damper testing in Loudwater

Other trades work around dampers all the time. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.

What we’re most often called out for:

  • Fire damper items raised by an assessor
  • Corroded dampers in damp risers and plant rooms
  • Gaps in the fire damper test log
  • Blades that jam part-way when released

If you manage a school site such as Christ Church Chorleywood CofE School, any fire dampers can be tested in the holidays.

What your quote should include

  • What records you’ll receive afterwards
  • Exactly which parts of the system are covered
  • What hours they’ll be on site
  • What insurance they carry

Our hiring checklist

How the job changes from site to site

Ceiling voids and risers

Damp plant areas are hard on dampers. We note any rust or water damage on the report so it can be dealt with.

Smoke dampers

Testing smoke dampers sometimes needs input from whoever looks after the control system. We plan that with you before the visit.

How it works

On the day, we arrive 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 first, and floors and nearby surfaces are sheeted. On site, it takes from an hour or two in a small building to several visits on a large estate. Rural roads and tight entrances are worth telling us about before a visit to Loudwater.

  1. We go through the damper schedule and any previous faults.
  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.

Before we arrive

  • Make sure equipment near the work can be switched off and left to cool
  • Mention any sign-in, permit or induction we need
  • Move anything stored near the system

How to get a quote
