What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Fire damper testing for kitchens and businesses in Coleman Green
A drop test is simple in principle: the blade is released, checked for a full close and reset. We do this for buildings in Coleman Green and across Hertfordshire, keeping a log for each damper so there’s a history to look back on. The work covers wall and floor dampers, riser dampers and hospitals and care homes, and common reasons people get in touch are buildings with no damper register and corroded dampers in damp risers and plant rooms.
In a village or hamlet like Coleman Green, there may be only a few buildings with fire dampers. Wherever there are dampers, each one needs testing at least annually.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Smoke dampers
Because they’re linked to controls, smoke damper tests can need some coordination. We agree the arrangements with you in advance.
Ceiling voids and risers
Where ductwork runs up through a building, there are often dampers at every floor. We work through them floor by floor so nothing is missed.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Add new dampers to the register as they’re fitted
- Keep to at least yearly testing
- Do not let hatches get painted shut or boarded over
- Keep an eye out for damp around dampers
Make sure trades working in ceilings and risers know where the dampers sit, and ask them not to run cables through or wedge them. Anything they disturb should be checked again.
The simplest way to avoid failures is to test on time, every year. Faults caught early are easier to fix.
What affects the quote in Coleman Green
There’s no set price list, because no two systems are the same. The quote depends on:
- How many systems or sites are involved
- The scale of the work
- A single visit or a regular plan
- Site rules, permits and inductions
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The postcode and the type of business
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- A few general shots of the system
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Coleman Green questions
Do you work overnight in Coleman Green?
Yes, nights and weekends are routine for us. That way a site in Coleman Green doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you work in villages like Coleman Green?
Yes, we work in villages as well as towns, and Coleman Green is covered. Just mention lanes, gates or anything else about the site when you book.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
What if a fire damper will not close?
Failed dampers are reported and we can quote to repair or replace them. After the repair, we test it again so the record shows a pass.
What happens to dampers you can’t get to?
Any damper we can’t reach is listed on the report so nothing is quietly missed. Fitting an access panel is the usual fix, and we can quote to fit one.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
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 so the area stays clean.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What a clean will not put right
Some problems need a different service or another trade:
- Fire alarm or control system faults behind a smoke damper
- Signing off a building’s overall fire safety
- Dampers that were never installed where they’re needed
If you’re not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer.

Common problems we fix in Coleman Green
The law puts a duty on the responsible person to keep fire safety systems, dampers included, in working order. Employers, owners, landlords and managing agents all need evidence that the dampers have been checked.
What we are most often called out for:
- Dampers clogged with dust or grease
- Dampers hidden with no access panel or hatch
- Motorised smoke dampers due for testing
- Rusted damper blades and springs
Shaw's Corner, about 2.5 miles north, is one of the historic houses near Coleman Green, and older buildings converted to new uses often have ventilation added later.
Before booking anyone

The process
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes anything from a couple of hours for a handful of dampers to a full day for a large building. A few pictures of the system help us make the most of a visit to a place like Coleman Green.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the 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
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
