Common questions in St James's
Does London parking affect a job in St James's?
A loading bay, a visitor permit or off-street space near the site in St James's makes the visit easier to plan. If the building has a loading slot system, we will book into it.
Can you come to St James's after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in St James's keeps running as normal. Your opening times are the first thing we ask for.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
How we handle fire damper testing in St James's
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. A drop test shows that the damper still does that when it matters, and we record the result for every damper we test. If you are dealing with dampers affected by leaks or condensation and smoke dampers that need testing through their controls, we can put it right, from riser dampers, motorised smoke dampers and hospitals and care homes onwards.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in St James's, that can mean dampers on every floor, many of them above ceilings or in risers.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Update the register when ductwork changes
- Never wedge or tie a damper open
- Make sure access panels stay clear and usable
- Brief other trades about dampers in ceilings and risers
After testing, you get a report listing each of the fire and smoke dampers we tested, with where it is and whether it passed. File it with your fire safety log so it’s ready when your assessor or insurer asks.
Deal with leaks and condensation near dampers quickly. Rusted parts are one of the main reasons dampers fail to close.
When something else is needed
We will always give you a straight diagnosis, so here’s what fire damper testing will not do:
- Holes around ductwork in fire-resisting walls
- Ductwork crossing a fire wall with no damper fitted
- Faults in the alarm or building controls that signal smoke dampers
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.

How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a few hours for a single floor, with bigger buildings phased over more than one visit. Before any visit in St James's, we agree where the van can stop and how equipment reaches the system.
- 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.
- Each one that passes is reset, ready to work.
- You get a report listing each damper, its result and any remedials needed.
Preparing for the visit
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Different parts, different methods
Schools, hospitals and care homes
In hospitals and care homes, people are there day and night. We plan the order of work with the site team to keep disruption to a minimum.
Fusible link fire dampers
Most fire dampers are held open by a fusible link. Heat melts the link and the blade falls shut across the duct. We release the blade, check it closes fully and reset it.
Leave it or put it right?
Sites in St James's tested every year build up a history for each damper so repeat problems show up early. If the same damper keeps giving trouble, the record shows it long before it fails outright. A busy site in St James's builds up dirt and wear quickly, so putting it off makes the eventual job larger.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.

Fire dampers in St James's buildings
Food Standards Agency records list about 94 schools, colleges and universities, about 44 hospitals, care homes and childcare premises and about 246 hotels and guest houses registered as food businesses across St James's and its immediate surroundings (about a mile and a half). Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. London buildings tend to have dampers on several floors, so testing is typically done out of hours, a zone at a time. The nearest hospital to St James's is St James Workhouse, about less than half a mile north-west. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed.
For schools like Soho Parish CofE Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. Hospitals such as St James Workhouse, about within half a mile north-west, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near St James's, the same annual testing applies. Historic houses near St James's, with Marlborough House about 0.3 miles south-west, are a reminder that older buildings can hold dampers in unexpected places.
