About our fire stopping in Eastwick
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations, and what we’re called in for most is open linear gaps along the top of fire-resisting walls and damaged fire seals in risers and voids. Whether you call it commercial sealant work, mastic application or joint sealing, in Eastwick it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Eastwick, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to call us in Eastwick
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Things that usually lead to an enquiry:
- Unsealed penetrations discovered above suspended ceilings
- Fire-stopping items raised at inspection or handover
- Unsealed joints where partitions meet the slab
- Fire stopping installed outside its tested range
Hospital estates such as Princess Alexandra Hospital, 0.9 miles south of Eastwick, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- What site paperwork they can supply
- How joint depth will be controlled
- Will failed sealant be removed rather than covered?
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Eastwick are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Flag any permit to work we’ll need
- Move anything stored against the joints
- Arrange parking or a loading space

Advice
Why deal with it now?
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Around Eastwick, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Why appoint us
- Fully insured
- Fixed quotes based on photos, drawings or a visit
- Joints cleaned back to sound surfaces
- One number for every site we cover

Questions about Eastwick
Does your area include sites such as Harlow Enterprise Centre, near Eastwick?
Yes. Estates, retail parks and business parks around Eastwick, Harlow Enterprise Centre among them, are all within reach. A few photos and the unit address let us price the work.
What does the BS 476 change mean for fire-rated sealant in Eastwick?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Where services cross fire walls in Eastwick
Central London is about 21 miles from Eastwick. Office refits around the commuter belt bring new cabling through fire-resisting walls. Eastwick has several hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
On a site such as Harlow Enterprise Centre, less than half a mile south-east of Eastwick, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. For a school such as Pemberley Academy, penetration sealing fits best at the end of the summer works.
Eastwick is about 2 miles north-west of Harlow, in Hertfordshire. Businesses, contractors and managing agents in Eastwick use us for work on service penetrations.

Eastwick’s nearest station is Harlow Town station, roughly 0.5 miles south-east. Other landmarks nearby include Princess Alexandra Hospital (0.9 miles south) and Mark Hall Cycle Museum (1.8 miles east). Open spaces near Eastwick include Hunsdon Mead.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
