What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Converted and older buildings near places like Benington tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- Work to your specification and the manufacturer’s guidance
- A fixed quote before work starts
- Fully insured

How the job changes by surface
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Walls or floors that aren’t fire-resisting to begin with
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Where we work in Benington

Advice
Service penetrations in Benington buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. At about 27 miles from central London, Benington is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Office fit-outs on sites such as Astonbury Farm & Business Park, 1.9 miles south-west of Benington, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Wherever services are added at a hospital such as Lister Hospital (4.8 miles north-west of Benington) the compartment line has to be made good with the specified product. For a building such as Parish Church of St Peter, new heating or data runs are the usual reason penetrations need sealing.
Benington is about 3 miles east of Stevenage, in Hertfordshire.

Around Benington
Around Benington, our work takes us to commercial buildings near The Bell Public House. For rail, the closest station is Watton-At-Stone station, roughly 2.8 miles south of the centre. Other landmarks nearby include Lister Hospital (4.8 miles north-west) and Benington Castle (under half a mile west). Green spaces nearby include Astonbury Wood.
Looking after the joints
After handover, a little attention goes a long way:
- File the specified details where the next contractor can find them
- Brief every trade that openings they make must be sealed
- Have penetrations checked while they can still be seen
- Keep general-purpose fillers away from compartment walls
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.

What else we do in Benington
Common questions from Benington clients
Is Benington too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How does the move away from BS 476 affect penetration seals in Benington?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How much does the work cost?
Every job gets its own fixed quote. To get one, call 01277 525 020 or email us with a description of the work.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
