About our fire damper testing in Cumnor
We’re often asked to take on annual damper testing by the people who look after buildings in and around Cumnor. If there’s a damper register or a set of drawings, share it with us, and we’ll plan the visit around the building’s hours. The work covers offices and schools, riser dampers and wall and floor dampers, and common reasons people get in touch are buildings with no damper register and fire dampers that haven’t been tested for over a year.
For a building in or near Cumnor, the visit is planned ahead, with access agreed in advance, and the test itself is the same as in any city building.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Act on failed dampers rather than leaving them on file
- Never wedge or tie a damper open
- Tell contractors where dampers are before they start work
- Book the next test before the year runs out
Any damper that failed is listed with the reason, along with an offer to repair or replace them. Once the work is done, the damper is tested again and the record updated.
Deal with leaks and condensation near dampers quickly. Rusted parts are one of the main reasons dampers fail to close.
Cumnor buildings and fire safety
Going by the FSA’s register, there are about 4 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Cumnor. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Cumnor’s nearest hospital, Radcliffe Infirmary, is about 3.6 miles north-east. 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. Oxfordshire Fire and Rescue Service covers Cumnor. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.
Appleton Manor, about 1.9 miles south-west, is one of the historic houses near Cumnor, and older buildings converted to new uses often have ventilation added later. If you manage a school site such as Cumnor Church of England School (Voluntary Controlled), any fire dampers can be tested in the holidays. Hospitals such as Radcliffe Infirmary, about 3.6 miles north-east, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Cumnor, the same annual testing applies.

FAQs for Cumnor
Do you work in villages like Cumnor?
Yes, we work in villages as well as towns, and Cumnor is covered. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Cumnor?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Cumnor needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or email us.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
What does fire damper testing cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, usually ready within one working day.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes a morning or an afternoon for a small number of dampers, longer where there are many. The timing of a visit to Cumnor is set by you, and the travel is our side of the planning.
- 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.
- We close everything up and send the results in a report.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
Get a fixed quote
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.

What the work involves, part by part
Access panels
Access panels sometimes get painted over, screwed shut or hidden by new ceilings. Letting us know where they are speeds the visit up.
Offices and retail
Each new fit-out brings a risk of damaged or covered dampers. A test after the works shows the dampers still close.
What happens if it’s left?
Your fire risk assessor or insurer may want evidence that dampers have been tested. Having a current report ready for a building in Cumnor saves a scramble when the question comes. It’s worth booking a check, because nobody sees inside a duct day to day.

How we price fire damper testing
There’s no set price list, because no two systems are the same. What we look at:
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- The number of sites or systems
- One-off work versus a regular cycle
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
We can often survey from pictures. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Honest limits
Before booking, it helps to know what’s not included:
- Missing dampers that a designer needs to specify
- Signing off a building’s overall fire safety
- Deciding where dampers should be fitted
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before booking.
