Nether Street questions
Who enforces fire safety at workplaces in Nether Street?
It’s Hertfordshire Fire and Rescue Service, which covers Nether Street. Failed dampers on a report should be followed by a record of the repair, so the file shows the problem was closed out.
Do you work overnight in Nether Street?
Yes, out-of-hours work is a big part of what we do. The work in Nether Street can fit around your hours. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
How long does fire damper testing take?
Expect it to take a few hours for a single floor, with bigger buildings phased over more than one visit. How easily we can reach the dampers makes the most difference, so we will confirm the time when we quote.
What happens if a damper fails its test?
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.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
About our fire damper testing in Nether Street
Ductwork can carry fire and smoke between compartments, and the damper is what stops it. A damper only does its job if the blade can drop fully. Regular drop testing is how that gets checked for the dampers in your building. If you have missing or out-of-date damper records and dirty dampers that may not close, we can help.
Testing in a small place like Nether Street is planned around the journey and access, and every damper is drop tested, reset and recorded, the same as anywhere.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What affects the quote in Nether Street
The diagnosis comes before the price. The main factors are:
- Site rules, permits and inductions
- The condition of the system
- The times the site is available
- Where the site is and how we reach it
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes from an hour or two in a small building to several visits on a large estate. Somewhere like Nether Street, lanes, gates and parking are worth mentioning in advance.
- First we check the schedule and the last set of results.
- We locate every damper and note any we cannot reach.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Dampers that pass are reset, and failures are logged with what we found.
- The report sets out the results, and we can quote to repair or replace failed dampers.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system

Related advice
Different parts, different methods
Ceiling voids and risers
Risers and service shafts often hold dampers at each floor. Testing goes floor by floor so each one is accounted for.
Smoke dampers
A smoke damper that does not respond to its controls is recorded as a fault, along with what we saw.
What we’re called out for in Nether Street
Links and springs age like any other part. A link can be damaged, painted over or swapped for the wrong one, and a tired spring may not drive the blade home, and that only becomes clear during a drop test.
It’s time to book a visit if you see:
- Motorised smoke dampers due for testing
- Damper actions from a fire risk assessment
- Gaps in the fire damper test log
- Dampers overdue for their annual drop test
For schools like Widford School, damper testing is easiest in the holidays, when corridors and ceilings are clear.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- What’s included in the scope, part by part
- What insurance they carry
- If they look at the system before pricing
Why act early in Nether Street
Leaving damper testing for another year doesn’t make the dampers any more likely to work. BESA guidance is to test at least annually, and a skipped year leaves a hole in your records as well. In a small place like Nether Street, a system that fails can take a site out of use.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or send us an email, and we will talk you through it.
