About our fire stopping in Roundbush
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and old intumescent sealant that has split away, on cable penetrations, service gaps in risers and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: in Roundbush, that means joint design, primers and backing rod as standard.
Rural conversions around Roundbush can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Which sealant the job calls for
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Location, for remote and island sites
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Clear photos of the problem areas
- The postcode of the building
- Your programme or deadline
- What the building is and how it’s used
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email a schedule or drawings to discuss it first.

Where services cross fire walls in Roundbush
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. At about 36 miles from central London, Roundbush 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, and the gaps need sealing with the specified product.
Holiday works at schools like Cold Norton Primary School often leave service openings to seal before pupils return. Older community buildings such as Parish Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Roundbush is about 3 miles south of Maldon, in Essex. Across the CM9 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 644 places in Essex. London is covered too, around 36 miles from Roundbush.
We take on service penetrations across the CM9 postcode area, whatever the building. Among the streets we cover are Fambridge Road, Burnham Road and Roundbush Road. Just outside Roundbush, we also work in Cold Norton (1 mile south-west), Farther Howegreen (1 mile west), Howegreen (1 mile west), Purleigh (1 mile west) and Great Canney (2 miles south-west). A short drive away, we cover Chelmsford (9 miles north-west), Basildon (12 miles south-west), Braintree (15 miles north), Maldon (3 miles north), Canvey Island (12 miles south) and Billericay (12 miles west).
Local landmarks in Roundbush
Around Roundbush, our work takes us to commercial buildings near The White Horse Public House. The closest station to Roundbush is North Fambridge station, roughly 2.4 miles south of the centre. The countryside around Roundbush includes Stow Maries Halt.
When to bring in 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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
After the work
After handover, these steps help:
- Leave fire sealant to cure fully before covering it
- Report damaged or disturbed seals as soon as they’re spotted
- Include service cupboards in routine inspections
- Record which product was used where
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.
How a job runs
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Roundbush are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Share the asbestos register for older buildings
- Arrange parking or a loading space
- Send any specification or drawings in advance

Signs you need fire stopping in Roundbush
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Common reasons buildings call us in:
- Fire stopping installed outside its tested range
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed penetrations discovered above suspended ceilings
- Head-of-wall gaps with no fire seal
On estates like Mapledean Industrial Estate, 1.1 miles to the south-east of Roundbush, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Roundbush: questions and answers
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Roundbush?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work at a site such as Mapledean Industrial Estate, by Roundbush?
Yes. We cover Roundbush and the area around it, including industrial estates, business parks and retail parks such as Mapledean Industrial Estate. A few photos and the unit address let us price the work.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
