Why it’s worth doing now in How Wood

Fire damper testing in How Wood
The idea behind drop testing is straightforward: we release the blade, watch it close fully, then reset it. We do this for buildings in How Wood and across Hertfordshire, logging each one so the record builds year on year. If you have dampers hidden with no access panel or hatch and dampers affected by leaks or condensation, we can put it right.
Buildings around How Wood may have just a handful of dampers, but each one still needs drop testing at least once a year, with the result recorded.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What else we do in How Wood
Fire damper testing in How Wood: local notes
Food Standards Agency records list about 10 caring premises (care homes, nurseries and hospitals) registered as food businesses within roughly a mile and a half of the centre of How Wood. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. About 1.8 miles east of How Wood is Napsbury Hospital, the nearest hospital. Where patients or residents may need help to leave a building, working dampers matter all the more. The fire and rescue service for How Wood is Hertfordshire 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.
Healthcare buildings such as Napsbury Hospital (about 1.8 miles east) rely on fire compartments, and the dampers in them need testing at least annually. Historic buildings that have had ventilation added later can hide dampers in awkward places; High Elms Manor, about 2.2 miles south-west, is one of the historic houses in the area around How Wood.

How Wood questions
Do you work at weekends in How Wood?
Yes, out-of-hours work is a big part of what we do. That way a site in How Wood doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Which fire service covers How Wood?
It’s Hertfordshire Fire and Rescue Service, which covers How Wood. If a fire safety officer audits the building, they may ask for the latest damper test records.
Is How Wood in your area?
Yes. Our technicians work in How Wood, as part of our area across London and the South East.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What if a damper has no access panel?
We do not leave it off the report; we note it as not reached. Once there’s a panel or a way through the ceiling, it can be tested.
What should I send you?
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. After that, simply phone us on 0345 646 2711, or email photos.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
What happens if a damper fails its test?
The fault is recorded and explained in the report. A repair or a replacement can follow as a remedial job and test it again.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Act on failed dampers rather than leaving them on file
- Keep an eye out for damp around dampers
- Diary the annual test well ahead
- Keep damper test reports with the fire safety log
Dampers we couldn’t reach are listed with the reason, such as no access panel or a blocked hatch. Access panels can be fitted so those dampers are tested on the next visit.
Clean ductwork means less dust and grease reaching the dampers. It makes sense to plan duct cleaning and damper testing together.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a morning or an afternoon for a small number of dampers, longer where there are many. In a smaller place like How Wood, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We go through the damper schedule and any previous faults.
- We locate every damper and note any we can’t reach.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Dampers that pass are reset, and failures are logged with what we found.
- We report the results and offer remedials on failed dampers.
Before we arrive
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Common problems we fix in How Wood
Links and springs age like any other part. Damaged or painted links and weak springs mean the blade may stop short, and that only becomes clear during a drop test.
Any of these means the system needs a check-up:
- Smoke dampers with no recent test
- Fire dampers that haven’t been tested for over a year
- Blades that jam part-way when released
- Rusted damper blades and springs
Wherever there are offices above shops, near How Wood station or elsewhere in How Wood, ductwork may cross fire-resisting floors, and any dampers need testing.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
