How we handle fire damper testing in Colney Street
Ductwork can carry fire and smoke between compartments, and the damper is what stops it. A damper only does its job if the blade can drop fully. Regular drop testing is how that gets checked in each part of the building. If you have smoke dampers that need testing through their controls and dust or grease build-up on damper blades, we can help, from offices and schools, riser dampers and motorised smoke dampers onwards.
Testing in a small place like Colney Street is planned around the journey and access, and the test itself is the same as in any city building.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits
A little care between visits keeps the system in better shape. We recommend:
- Brief other trades about dampers in ceilings and risers
- Never wedge or tie a damper open
- Keep the damper register up to date after any building work
- Report leaks or condensation near ductwork quickly
If we couldn’t get to a damper, the report says so and why, such as no access panel or a blocked hatch. Access panels can be fitted so those dampers are tested on the next visit.
Good access is half the battle. Where there’s no hatch, an access panel makes testing possible ahead of the next visit.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
FAQs for Colney Street
Who is the fire and rescue service for Colney Street?
That is Hertfordshire Fire and Rescue Service. Failed dampers on a report should be followed by a record of the repair, so the file shows the problem was closed out.
Do you do school damper testing in Colney Street in the summer holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Colney Street. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How often do fire dampers need drop testing?
At least once a year, under BESA guidance, plus a test when the damper is first installed. Some sites choose to test more often where the risk is higher.
What paperwork do we get after testing?
We test, record and report, rather than certify dampers to a standard. For each damper it shows the result and anything that needs putting right.
Is a quote from pictures possible?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Common problems we fix in Colney Street
Links and springs age like any other part. Damaged or painted links and weak springs mean the blade may stop short, which only shows up when the damper is dropped.
Most sites get in touch when they notice something like this:
- Fire dampers with no recent test record
- Damper actions from a fire risk assessment
- Dampers that stick or won’t close fully
- Rusted damper blades and springs
Historic buildings that have had ventilation added later can hide dampers in awkward places; High Elms Manor, about 2.9 miles west, is one of the historic houses in the area around Colney Street.
Questions to ask before booking
- Whether a survey comes first
- How they set the interval to the next visit
- Whether the price is fixed
- Whether a written report and photos are included
How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the fire damper testing, clear away and leave you the report. On site, the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. Rural roads and tight entrances are worth telling us about before a visit to Colney Street.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site

Leave it or put it right?
Leaving damper testing for another year doesn’t make the dampers any more likely to work. BESA guidance is to test at least annually, and a skipped year leaves a hole in your records as well. In a small place like Colney Street, a system that fails can take a site out of use.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
