Need fire stopping in Wickstreet?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Site staff or a sealant specialist?

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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Fire stopping for commercial buildings in Wickstreet

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. Most enquiries involve expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, across service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Wickstreet tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Wickstreet 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 covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What happens if it’s left?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. One visit to deal with every failing joint makes more sense than several trips to a place like Wickstreet, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • One phone line for London, the South East and Scotland
  • 12-month guarantee on workmanship
  • CHAS accredited contractor
  • A fixed quote before work starts

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Approving the work on behalf of building control
  • Reviewing a building’s overall fire safety
  • Writing the fire-stopping specification

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Cable penetrations
  • Pipe penetrations
  • Joints between fire-resisting walls and floors
  • Linear gaps at wall heads

Your questions answered

Is Wickstreet off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What happens to BS 476 references for fire stopping in Wickstreet?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Wickstreet, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in

Where services cross fire walls in Wickstreet

Wickstreet lies roughly 46 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

Shop fits in centres such as Hailsham Retail Park (2.6 miles east of Wickstreet) can bring new services through fire-resisting walls between units, which then need the specified seal. Holiday works at schools like Bede's Prep School often leave service openings to seal before pupils return. Offices at parks like Deanland Business Park (to the north of Wickstreet) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Wickstreet is about 3 miles west of Hailsham, in East Sussex. We send applicators to Wickstreet for service penetrations, handled exactly as we handle every other area. Wickstreet is one of 308 places in East Sussex on our list. There’s a separate page for Brighton, roughly 14 miles from Wickstreet.

Anyone looking for fire stopping in BN26 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Wickstreet, we cover Arlington (1 mile south), Berwick (2 miles south-west), Ripe (2 miles north-west), Selmeston (2 miles south-west) and Golden Cross (2 miles north). Further afield, our area takes in Eastbourne (7 miles south-east), Bexhill-on-Sea (12 miles east), Seaford (7 miles south-west), Lewes (8 miles west), Hailsham (3 miles east) and Crowborough (13 miles north).
