Fire damper testing in Sheet's Heath, done properly
Some dampers haven’t been tested since the day they went in. Ceilings have gone up, access panels have been covered or lost, and the records have gone missing. We locate and test the dampers we can reach and record the ones we can’t, so you know where the gaps are. Common call-outs are for fire dampers that haven’t been tested for over a year and rusted damper blades and springs, on offices and schools, hospitals and care homes and wall and floor dampers.
Somewhere as small as Sheet's Heath, fire dampers are normally found in a school, a care home, a hotel or a converted building, wherever there is one. Wherever there are dampers, each one needs testing at least annually.
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.

Fixed quotes for fire damper testing in Sheet's Heath
The price is fixed before any work begins. It takes into account:
- How easy every part is to reach
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Part by part
Smoke dampers
A smoke damper that does not respond to its controls is recorded as a fault, with a note of what we found.
Ceiling voids and risers
Ceiling voids are where lots of dampers end up. We lift tiles where needed and put them back as we found them.
Common problems we fix in Sheet's Heath
Corrosion is another common cause of failure. Condensation, leaks and damp plant rooms corrode the parts that need to move, so a damper can seize without anyone noticing.
Signs it’s time to call us include:
- Dampers overdue for their annual drop test
- Rusted damper blades and springs
- Dust or grease build-up on damper blades
- Dampers that can’t be reached without an access panel
The nearest hospital, Brookwood Hospital, is about 0.9 miles east; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly.
What to look for in a quote
- Whether the price is fixed
- Whether the quote shows VAT
- What insurance they carry
- Exactly which parts of the system are covered
Between visits
How long the results last depends on use and care. We suggest:
- Keep the damper register up to date after any building work
- Don’t let anything obstruct a damper’s blade
- Act on failed dampers rather than leaving them on file
- Keep to at least yearly testing
The next test should be no more than a year away. BESA guidance is at least annual testing, so it helps to book it before the date slips.
Where a damper sits in ductwork that collects dust or grease, keeping that ductwork clean helps. It makes sense to plan duct cleaning and damper testing together.
Common questions in Sheet's Heath
Is Sheet's Heath within the area you cover?
Yes. Sheet's Heath is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can the work in Sheet's Heath be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Sheet's Heath keeps running as normal. Tell us your opening hours when you ask for a quote.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Do you certify fire dampers?
What you receive is a written report of each test, damper by damper. Any failures come with a note of the remedials needed.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Somewhere as small as Sheet's Heath, the date and timings are agreed with you well before the day.
- We go through the damper schedule and any previous faults.
- 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.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When it’s something else
Some problems need a different service or another trade:
- Holes around ductwork in fire-resisting walls
- Signing off a building’s overall fire safety
- Faults in the alarm or building controls that signal smoke dampers
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.
What we work on in Sheet's Heath

Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually.

Sheet's Heath is covered by Surrey 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.

If you manage offices, shops or flats near Brookwood station, the ductwork in them may pass through fire-resisting walls and floors, and any dampers need testing at least once a year.
