How we price fire damper testing
The survey tells us what the work involves. The main factors are:
- Parking and loading at the site
- The condition of the system
- The times the site is available
- Site rules, permits and inductions
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
Helping us quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
How we handle fire damper testing in Cranford
A drop test is simple in principle: we release the blade, watch it close fully, then reset it. We test dampers for sites in Cranford and the rest of Greater London, logging each one so the record builds year on year. We are often asked to deal with rusted damper blades and springs and dampers overdue for their annual drop test, on wall and floor dampers, fusible link fire dampers and hospitals and care homes.
In a London area like Cranford, testing has to fit around tenants, residents, guests or patients, so we work floor by floor or out of hours. We agree access to ceilings, risers and plant rooms with the building before work begins.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Why deal with it now?
If a damper cannot close, the wall it sits in has a hole in it during a fire. The rest of the compartment can be built perfectly and still be bypassed by the duct. It’s far better to find that out on a test than in a fire. Leaving it on a busy London site only adds to the work.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before work begins.

Cranford: your questions answered
Can the work in Cranford be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you test school fire dampers in Cranford out of term?
Yes. The holidays are the usual time for school work. Around Cranford, the Food Standards Agency lists about 22 schools and colleges with registered kitchens within a mile and a half or so. Just call us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
How do you deal with dampers that cannot be reached?
It goes on the report as inaccessible, with the reason. Access panels can be installed so the damper can be tested next time.
Do we need to close while you work?
Typically not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
How much time does a damper test visit need?
Typically the work takes from an hour or two in a small building to several visits on a large estate. It comes down mainly to how many dampers there are and how easy they are to get to.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
What happens on the day
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few hours for a single floor, with bigger buildings phased over more than one visit. In Cranford, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- 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.
- We reset every damper that passes and check it’s left open.
- The results go into a report, with failed dampers and remedials listed.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
Getting a quote

Advice
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What fire damper testing looks like in Cranford
Going by the FSA’s register, there are about 22 schools, colleges and universities, about 20 hospitals, care homes and childcare premises and about 19 hotels, B&Bs and guest houses serving food within roughly a mile and a half of the centre of Cranford. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Ceiling voids and risers in London buildings can hold many dampers, and each one has to be reached and recorded. Hounslow Hospital is the nearest hospital, about 1.6 miles east of Cranford. Hospitals are a good example of a building with fire dampers across many floors and departments.
Historic houses near Cranford, with Osterley House about 2.6 miles east, are a reminder that older buildings can hold dampers in unexpected places. Site managers at schools such as Cranford Primary School typically find the summer break the easiest time for ceiling work like damper testing. If you manage a care home or clinic near Cranford, the testing that a hospital like Hounslow Hospital (about 1.6 miles east) relies on applies to your dampers too.
Cranford is about 2 miles north of Feltham, in Greater London. We provide fire damper testing for businesses, landlords and public buildings in Cranford and the rest of Greater London. Across Greater London, we cover 764 places, and Cranford is one of them. There’s also a page for London, roughly 14 miles from Cranford.
Fire damper testing in TW4, TW5 and UB3 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Ely Road, Park Lane and The Avenue and nearby roads. Close by, we work in Hatton (1 mile south-west), Harlington (1 mile north-west), Heathrow (2 miles west), Feltham (2 miles south) and Sipson (2 miles north-west).

Local landmarks in Cranford
Locally, jobs take us to businesses close to Cranford Community College, The Queen's Head pub and Hounslow Heath and the streets around them. For rail, the closest station is Hayes & Harlington station, about 1.9 miles north of the centre. Other landmarks nearby include Hounslow Hospital (1.6 miles east) and Treaty Centre (2 miles east). Not far away are Garden Lake and Northala Fields.
Looking after it afterwards
Once we have finished, these simple steps help:
- Keep damper test reports with the fire safety log
- Keep an eye out for damp around dampers
- Don’t let anything obstruct a damper’s blade
- Warn anyone working in ceiling voids about the dampers
If we couldn’t get to a damper, the report says so and why, such as no access panel or a blocked hatch. Access panels can be fitted so those dampers are tested on the next visit.
Keep a damper register: where each damper is, what kind it is and when it was last tested. It means nothing gets forgotten when staff or contractors change.
When it’s something else
It’s worth knowing the limits before booking:
- Fire alarm or control system faults behind a smoke damper
- Fire risk assessments, which need a fire risk assessor
- Dampers that were never installed where they’re needed
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.

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. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
