About our fire damper testing in Sunninghill
Testing finds the dampers that will not close. When one sticks, has a damaged link or is corroded, we report it and offer remedials rather than leaving you with a problem and no fix. The work covers wall and floor dampers, motorised smoke dampers and riser dampers, and common reasons people get in touch are smoke dampers with no recent test and damper actions from a fire risk assessment.
Around a place like Sunninghill, dampers tend to be in schools, care homes, surgeries and hotels rather than big offices. The law on keeping them working doesn’t change with the size of the place.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes anything from a couple of hours for a handful of dampers to a full day for a large building. Getting to the system matters more than parking in a place like Sunninghill, so let us know how to reach it.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- 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.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Let us know when the site is closed or quiet

How we price fire damper testing
The price is fixed before any work begins. It takes into account:
- Where the site is and how we reach it
- The scale of the work
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
What we need to know
When you contact us, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- Any access panels or hatches you can see
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
Why deal with it now?
Sites in Sunninghill tested every year build up a history for each damper so repeat problems show up early. If the same damper keeps giving trouble, the record shows it before it becomes a failure. It’s easy to lose track of when the work was last done on a quieter site.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.

Common problems we fix in Sunninghill
Corrosion is another common cause of failure. Water leaks, condensation and damp plant areas attack the casing, blade and spring, and the damper can seize quietly where no one sees it.
These are the problems we see most often:
- Smoke dampers that need testing through their controls
- Dirty dampers that may not close
- Fire damper items raised by an assessor
- Fire dampers nobody can get to
For schools like St Michael's CofE Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

Fire dampers in Sunninghill buildings
Food Standards Agency records list about 15 schools, colleges and universities, about 10 caring premises (care homes, nurseries and hospitals) and about 3 hotels, B&Bs and guest houses registered as food businesses within 1.5 miles or so of the middle of Sunninghill. 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. Sunninghill is covered by Royal Berkshire Fire and Rescue Service. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. The nearest hospital to Sunninghill is Heatherwood Hospital, about 1.5 miles north-west. 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.
St Leonard's Hill, about 4.6 miles north, is one of the historic houses near Sunninghill, and older buildings converted to new uses often have ventilation added later. If you manage a care home or clinic near Sunninghill, the testing that a hospital like Heatherwood Hospital (about 1.5 miles north-west) relies on applies to your dampers too.

Common questions in Sunninghill
Is Sunninghill within the area you cover?
Yes, Sunninghill is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can a school’s dampers in Sunninghill be tested out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 15 schools and colleges with food registrations within roughly a mile and a half of Sunninghill. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do we lose a day’s trading?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
How long will damper testing take?
Typically the work takes from an hour or two in a small building to several visits on a large estate. The number of dampers and how they’re reached decide the rest.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you test smoke dampers as well?
Yes. Smoke dampers are motorised, so we test them by operating them through their controls. Each one is checked for full travel and the result recorded.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Add new dampers to the register as they’re fitted
- File every damper report where your assessor can find it
- Keep cables and fixings away from damper blades
- Diary the annual test well ahead
Failed dampers are set out separately, each with the fault we found, and we can quote for remedials. After a repair, we retest the damper and update the record.
Clean ductwork means less dust and grease reaching the dampers. Duct cleaning and damper testing can be planned side by side.
What the work involves, part by part
Fusible link fire dampers
The link has to be in good order for the damper to work. We check its condition during the test and any problems go on the report.
Schools, hospitals and care homes
In hospitals and care homes, people are there day and night. The sequence of testing is agreed with staff to keep disruption to a minimum.
