Fire damper testing in Preston, done properly
Smoke dampers work differently from fire dampers. Smoke dampers are motorised and are opened and closed by a control system, so testing means running them through their controls and checking that each blade moves fully and returns. The work covers hospitals and care homes, wall and floor dampers and fusible link fire dampers, and people most often call us about smoke dampers with no recent test and dampers overdue for their annual drop test.
In a village or hamlet like Preston, there may be only a few buildings with fire dampers. Wherever there are dampers, each one needs testing at least annually.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How we price fire damper testing
A fixed price needs a few facts first. We look at:
- A single visit or a regular plan
- The scale of the work
- Site rules, permits and inductions
- Working hours and out-of-hours timing
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Wide photos of the system and the area around it

Honest limits
A few issues sit outside what this work can do:
- Fire-stopping gaps around the duct where it passes through the wall
- Missing dampers that a designer needs to specify
- Fire risk assessments, which need a fire risk assessor
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.

- Each damper is found and checked for access.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.

Preston buildings and fire safety
Lister Hospital is the nearest hospital, about 3.3 miles east of Preston. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. The fire and rescue service for Preston is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty.
If you manage an older building converted to a hotel or venue, like many historic houses in the area (Knebworth House is about 3.9 miles south-east), finding every damper is the first job. Hospitals such as Lister Hospital, about 3.3 miles east, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Preston, the same annual testing applies. For schools like Preston Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

What happens if it’s left?
A damper that’s stuck open gives fire and smoke a route straight through a fire-resisting wall. The rest of the compartment can be built perfectly and still be bypassed by the duct. Testing now is how you find out before it matters. A fault that closes a site in a village like Preston affects everyone who depends on it.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Never wedge or tie a damper open
- Diary the annual test well ahead
- Keep ceiling hatches and duct panels easy to open
- Add new dampers to the register as they’re fitted
If we couldn’t get to a damper, the report says so and why, for example a missing panel or a covered hatch. We can fit access panels so they can be tested next time.
Deal with leaks and condensation near dampers quickly. Corrosion is a common reason blades stick.
How the job changes from site to site
Smoke dampers
Testing smoke dampers sometimes needs input from whoever looks after the control system. We plan that with you before the visit.
Ceiling voids and risers
Plant rooms and risers can be damp, which leads to corrosion. We note any rust or water damage on the report so it can be dealt with.

FAQs for Preston
Can you work in Preston outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Preston does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Can you get to a site in Preston?
Yes, Preston is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. That’s generally the employer or the person in control of the premises, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What paperwork do we get after testing?
After testing, we provide a report covering each damper, with its location, its result and any faults. Keep it with your fire safety records.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What if a fire damper will not close?
The fault is recorded and explained in the report. A repair or a replacement can follow as a remedial job with a fresh test at the end.
