Fire damper testing for kitchens and businesses in Kemprow
BESA guidance is that fire dampers should be tested by a competent person when they’re installed and at least annually after that. Spring-operated dampers need testing every year as a minimum. We carry out fire damper testing for buildings in Kemprow and give you the records to show it’s been done. The work covers riser dampers, wall and floor dampers and offices and schools, and the jobs we see most are dampers that stick or won’t close fully and fire dampers that haven’t been tested for over a year.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. The first visit starts by locating each damper.
Duct Doctor has been trading since 2009, and we’re 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.

Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Tell contractors where dampers are before they start work
- Fix water leaks in plant rooms and risers promptly
- Close off damper faults promptly
- Diary the annual test well ahead
If we couldn’t get to a damper, the report says so and why, such as no access panel or a blocked hatch. We can fit access panels so they can be tested next time.
Keeping to at least annual testing stops small faults turning into failed dampers. Faults caught early are easier to fix.
Managing agents and facilities teams in Kemprow
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Fixed quotes for fire damper testing in Kemprow
A fixed price needs a few facts first. We check:
- Parking and loading at the site
- How big the system is
- The number of sites or systems
- Working hours and out-of-hours timing
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Asking for a quote
There’s no need for technical detail. Just send:
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Your last certificate, test record or report
For a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
What staff can safely do
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.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Leave it or put it right?
Until a damper has been dropped, you can’t say whether it works. Testing turns it into a known pass or a known fault, with remedials offered for anything that fails, and that is something you can plan around. It’s simpler to plan the work at Kemprow now than to arrange it in a hurry later.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before work begins.
What you get with us
- Photo reports with every job
- We diagnose before we treat
- A single point of contact for sites across the South East and London
- Fully insured

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 we clear up before we go. We agree a date with you, plan the drive to Kemprow and turn up when the site is quiet.
- We gather what’s known about the dampers, from drawings, registers or past reports.
- Dampers are located one by one and reached through their access panels.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- Dampers that close fully are reset and left open.
- The results go into a report, with failed dampers and remedials listed.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
- Clear loose items from the work area

Advice
What we are called out for in Kemprow
Corrosion is another common cause of failure. Condensation, leaks and damp plant rooms corrode the parts that need to move, and the damper can seize quietly where no one sees it.
What we’re most often called out for:
- Dampers overdue for their annual drop test
- Dampers clogged with dust or grease
- Fire dampers that fail to drop shut
- Smoke dampers that need testing through their controls
School buildings such as Fair Field Junior School are normally tested in the holidays, wherever they have dampers.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- If they look at the system before pricing
- How areas they can’t reach will be recorded
- Whether the work can be done while the site is closed

Questions from Kemprow
Can you get to a site in Kemprow?
Yes, we work in villages as well as towns, and Kemprow is covered. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Kemprow?
Yes, out-of-hours work is a big part of what we do. It means the site in Kemprow keeps running as normal. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
How long does fire damper testing take?
It takes a few hours for a single floor, with bigger buildings phased over more than one visit. How easily we can reach the dampers makes the most difference, so we will confirm the time when we quote.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. 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.
Can you price the work without visiting?
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.
Do you test smoke dampers as well?
Yes. We test smoke dampers through their control system, as they’re motor driven. Each one is checked for full travel and the result recorded.
What paperwork do we get after testing?
We test, record and report, rather than certify dampers to a standard. It lists each damper, the result and any remedials needed.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
