Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Fire damper testing for kitchens and businesses in Sandon
Not every damper relies on heat. A smoke damper is driven by a motor and responds to signals from its controls, so we test them by operating them through those controls and checking that each blade moves fully and returns. If you have dirty dampers that may not close and dampers overdue for their annual drop test, we can help.
For a building in or near Sandon, the visit is planned ahead, with access agreed in advance, and every damper is drop tested, reset and recorded, the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Why it’s worth doing now in Sandon
A damper that’s stuck open gives fire and smoke a route straight through a fire-resisting wall. 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. Systems in rural buildings are often out of sight and out of mind.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in Sandon and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a couple of hours for a few dampers, and a day or more across a big site, and the area is cleaned down before we leave. The timing of a visit to Sandon is set by you, and the travel is our side of the planning.
- We start with whatever records exist: registers, drawings or old reports.
- Dampers are located one by one and reached through their access panels.
- We release each fire damper blade and operate smoke dampers from their controls.
- Dampers that close fully are reset and left open.
- We report on every damper, with faults and suggested remedials set out.
Preparing for the visit
- Let us know about permits to work or site inductions
- Clear loose items from the work area
- Have your last certificate or report to hand
How to get a quote
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call 0345 646 2711, or email photos.
Advice
Keeping the system healthy
After the visit, a few habits help the work last:
- Add new dampers to the register as they’re fitted
- Diary the annual test well ahead
- Close off damper faults promptly
- Fix water leaks in plant rooms and risers promptly
Tell other contractors where the dampers are, and ask them not to run cables through or wedge them. Anything they disturb should be checked again.
Clean ductwork means less dust and grease reaching the dampers. Duct cleaning and damper testing can be planned side by side.
Sandon: your questions answered
Do you work overnight in Sandon?
Yes, evening, overnight and weekend work is normal for us. That way a site in Sandon does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Sandon within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Sandon included. The journey is planned ahead, so a few details about the route help.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How much does fire damper testing cost in Sandon?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
More services for Sandon
What we are called out for in Sandon
Dampers are hidden above ceilings, inside risers and behind boxing. Without an access panel nearby, they’re easy to forget, and one that can’t be reached can’t be tested.
Most sites get in touch after spotting one of these:
- Blades that jam part-way when released
- Dampers affected by leaks or condensation
- Dampers hidden with no access panel or hatch
- Missing or out-of-date damper records
School buildings such as Sandon Junior Mixed and Infant School are typically tested in the holidays, wherever they have dampers.
