What affects the quote in Harmer Green
Your quote is based on your site. We consider:

- Where the site is and how we reach it
- Site rules, permits and inductions
- How easy every part is to reach
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
When you contact us, it’s useful to have:

About our fire damper testing in Harmer Green
Not every damper relies on heat. A smoke damper is driven by a motor and responds to signals from its controls, so testing means running them through their controls and checking that each blade moves fully and returns. We are often asked to deal with dampers that can’t be reached without an access panel and fire damper items raised by an assessor, on hospitals and care homes, fusible link fire dampers and riser dampers.
Somewhere as small as Harmer Green, fire dampers are usually 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

When to call us in Harmer Green
Building work often happens right next to dampers. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
If you notice any of these, it’s worth a diagnosis:
- Dampers affected by leaks or condensation
- Blades that jam part-way when released
- Smoke dampers that need testing through their controls
- Dust or grease build-up on damper blades
For managed buildings around Welwyn North station, damper testing can be booked out of hours so tenants aren’t disturbed.
What to look for in a quote
- Proof of accreditation you can verify
- When the next visit should be, and why
- What’s included in the scope, part by part
- Whether they’re fully insured
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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. Leave those to us.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Harmer Green and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
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 Harmer Green
Food Standards Agency data includes about 10 schools, colleges and universities and about 8 hospitals, care homes and childcare premises within about 1.5 miles of central Harmer Green. If any of them has ducted ventilation, its dampers need an annual drop test at least. The fire and rescue service for Harmer Green is Hertfordshire Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. About 3.4 miles south of Harmer Green is Queen Elizabeth II Hospital, the nearest hospital. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have.
A school like Oaklands Primary School can have any dampers tested over half-term without disturbing lessons. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Digswell House is about 1.5 miles south-west), finding every damper is the first job.

Common questions in Harmer Green
Who enforces fire safety at workplaces in Harmer Green?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Harmer Green. BESA guidance is that every fire damper is tested at least once a year, so an officer or insurer may expect a report less than a year old.
Can you work in Harmer Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Harmer Green can fit around your hours. Your opening times are the first thing we ask for.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Can you test motorised smoke dampers?
Yes. Smoke dampers are motorised, so we test them by operating them through their controls. Each one is checked for full travel and the result recorded.
Is a quote from photos possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we will say so.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Do we need to close while you work?
Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
What a clean won’t put right
A few issues sit outside what this work can do:
- Faults in the alarm or building controls that signal smoke dampers
- Gaps in the wall or floor around the damper
- Deciding where dampers should be fitted
If in doubt, call 0345 646 2711, or send details by email and we will say what we think.
Parts of the system we cover
- Wall and floor dampers
- Motorised smoke dampers
- Fusible link fire dampers
- Riser dampers
- Offices and schools
- Hospitals and care homes
Different parts, different methods
Smoke dampers
A smoke damper that does not respond to its controls is recorded as a fault, along with what we saw.
Offices and retail
In offices and retail units, dampers tend to be hidden above working areas. We can test in the evening, overnight or at weekends so the space stays open.
How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a couple of hours for a few dampers, and a day or more across a big site. Seeing the system in photos first means the trip to Harmer Green can be planned properly.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- We release each blade and check it shuts all the way.
- The damper is reset and its condition noted.
- Panels and tiles go back, and the results are written up.
Before we arrive
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or email us.
