- Corroded dampers in damp risers and plant rooms
- Smoke dampers with no recent test
- Dampers hidden with no access panel or hatch
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Don’t let anything obstruct a damper’s blade
- Keep to at least yearly testing
- Make sure access panels stay clear and usable
- File every damper report where your assessor can find it
Pass the report to whoever keeps your fire risk assessment up to date so their assessment matches what was found. Faults on the report are worth closing off quickly.
Deal with leaks and condensation near dampers quickly. Corrosion is a common reason blades stick.
Fire damper testing in Boxmoor, done properly
Smoke dampers work differently from fire dampers. Smoke dampers are motorised and are opened and closed by a control system, so we test them by operating them through those controls and checking that each blade moves fully and returns. The work covers wall and floor dampers, offices and schools and riser dampers, and the jobs we see most are smoke dampers that need testing through their controls and rusted damper blades and springs.
Around a place like Boxmoor, dampers tend to be in schools, care homes, surgeries and hotels rather than big offices. The duty to keep them working is the same as in a city.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Common questions in Boxmoor
Can you work in Boxmoor outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can fire dampers in schools around Boxmoor be tested in the holidays?
Yes, out-of-term visits are normal for schools. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Boxmoor. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will we get a certificate for the dampers?
What you receive is a written report of each test, damper by damper. Failures are set out with the remedials we’d suggest.
What if a damper has no access panel?
Any damper we cannot reach is listed on the report, so you know exactly what’s outstanding. An access panel tends to solve it, and we can quote to fit one.
Who has the duty to keep fire dampers working?
The duty falls on the responsible person for the premises. Depending on the building, that can be the employer, owner, landlord or whoever manages it. Our part is the testing and the records that show it’s been done.
What if parts of the system cannot be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you carry out smoke damper testing?
Yes. We operate each smoke damper from its controls and check it opens and closes fully. If someone else looks after the controls, we plan the timing with you.
What happens if a damper fails its test?
Failed dampers are reported and we can quote to repair or replace them. After the repair, we test it again so the record shows a pass.
Why act early in Boxmoor
If a damper cannot close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. It’s easy to lose track of when the work was last done on a quieter site.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What we are called out for in Boxmoor
Over time, dust builds up on the blade, the runners and the spring. Where the duct carries grease or cooking vapour, grease coats them too, and either one can hold the blade part-open.
Signs it’s time to call us include:
- Dampers that cannot be reached without an access panel
- Fire dampers that haven’t been tested for over a year
- Smoke dampers that need testing through their controls
- Dampers that stick or will not close fully
For managed buildings around Hemel Hempstead station, damper testing can be booked out of hours so tenants aren’t disturbed.
Questions to ask before you book
- How VAT is shown on the quote
- How they set the interval to the next visit
- How areas they can’t reach will be recorded
- What hours they’ll be on site
What affects the quote in Boxmoor
We do not publish a price list, because no two systems are the same. What we look at:
- Access, including roofs, risers and ceiling voids
- The scale of the work
- What state the system is in
- Whether several sites go on one quote
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, phone us on 0345 646 2711 or send us an email.
Honest limits
It’s worth knowing the limits before booking:
- Approving the building’s fire strategy
- Control wiring problems outside the damper itself
- Fire risk assessments, which need a fire risk assessor
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly before you book.

Different parts, different methods
Schools, hospitals and care homes
Buildings where people sleep or need help to leave rely heavily on compartments holding fire back. Regular damper testing supports that.
Access panels
Testing depends on getting to the damper. Most need an access panel in the duct and a hatch in the ceiling or wall.
Fire dampers in Boxmoor buildings
Food Standards Agency records list about 20 schools, colleges and universities, about 26 caring premises (care homes, nurseries and hospitals) and about 3 hotels and guest houses registered as food businesses within roughly a mile and a half of the centre of Boxmoor. If any of them has ducted ventilation, its dampers need an annual drop test at least. About 0.7 miles north-east of Boxmoor is Hemel Hempstead Hospital, the nearest hospital. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have. The fire and rescue service for Boxmoor is Hertfordshire Fire and Rescue Service. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.
School buildings such as Boxmoor Primary School are typically tested in the holidays, wherever they have dampers. Hospitals such as Hemel Hempstead Hospital, about 0.7 miles north-east, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Boxmoor, the same annual testing applies.

What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours for a few dampers, and a day or more across a big site. Tell us when your site near Boxmoor is quiet and the visit will be booked for then.
- We plan access and timing with you first, including any out-of-hours work.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- The blade is released and watched to make sure it closes fully.
- We reset it and record any dirt, corrosion or damage.
- Panels and tiles go back, and the results are written up.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
