Fire damper testing in Knaphill, done properly
A drop test is simple in principle: the blade is released, checked for a full close and reset. We do this for buildings in Knaphill and across Surrey, keeping a log for each damper so there’s a history to look back on. Typical jobs include damper actions from a fire risk assessment and fire dampers that fail to drop shut, on motorised smoke dampers, fusible link fire dampers and riser dampers.
In a smaller place like Knaphill, buildings with fire dampers are more likely to be a school, a surgery, a care home or a hotel than an office block. The duty to keep them working is the same as in a city.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Knaphill
Testing every year builds a history for each damper, which shows patterns early. A damper that was slow last year and sticks this year tells you something long before it fails outright. Even a site near Knaphill that is only busy part of the week needs its system checked on a schedule.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.
Why Knaphill businesses choose us

What we’re called out for in Knaphill
Links and springs age like any other part. A link can be damaged, painted over or swapped for the wrong one, and a tired spring may not drive the blade home, and that only becomes clear during a drop test.
Any of these means the system needs a check-up:
- Fire dampers with no recent test record
- Blades that jam part-way when released
- Missing or out-of-date damper records
- Smoke dampers that need testing through their controls
If you manage a care home or clinic near Knaphill, the testing that a hospital like Brookwood Hospital (about under half a mile south) relies on applies to your dampers too.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a few hours for a single floor, with bigger buildings phased over more than one visit, and the area is cleaned down before we leave. We plan the journey to Knaphill and bring what the job is likely to need.
- 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.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Getting ready for the visit
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards

Knaphill buildings and fire safety
Going by the FSA’s register, there are about 4 schools, colleges and universities and about 10 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Knaphill. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Brookwood Hospital is the nearest hospital, about under half a mile south of Knaphill. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. Knaphill is covered by Surrey Fire and Rescue Service. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises.
A school like Knaphill School can have any dampers tested over half-term without disturbing lessons.

What the work involves, part by part
Fusible link fire dampers
Spring-operated fire dampers need testing at least once a year. A weak spring or a sticking blade shows up when the damper is dropped.
Smoke dampers
Testing smoke dampers sometimes needs input from whoever looks after the control system. We plan that with you before the visit.
Knaphill questions
Do you do school damper testing in Knaphill in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Knaphill, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call us on 0345 646 2711, or email photos, and we will fit the work in.
Do you cover smaller places like Knaphill?
Yes. Knaphill is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711 or send us an email.
Do we need to close while you work?
Not typically. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How long does fire damper testing take?
Typically the work takes a couple of hours for a few dampers, and a day or more across a big site. The number of dampers and how they’re reached decide the rest.
