About our fire stopping in Hastings

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations, and the failures we are asked to look at most are fire-stopping items raised at inspection or handover and seals that don’t match their tested detail. Whoever orders the work in Hastings, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Bigger buildings around a town like Hastings are often done in sequence: services first, then penetration and linear seals. Design and sign-off of fire stopping rest with the designer, fire engineer or building control; we install what has been specified.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Town-centre jobs in Hastings can mean limited parking and loading, while out-of-town estates usually have yards and car parks. Either way, tell us what’s available.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  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.

Getting the site ready

  • Arrange parking or a loading space
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

When to call us in Hastings

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.

What tends to prompt an enquiry:

  • Fire sealant pulled out of the opening
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping
  • Seals that don’t match their tested detail

For a building such as St Luke's Church, new heating or data runs are the usual reason penetrations need sealing.

Comparing quotes

  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?
  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations

How to choose a sealant contractor

After the work

A few simple habits keep the new joints working:

  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs
  • Brief every trade that openings they make must be sealed
  • Report damaged or disturbed seals as soon as they’re spotted

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.

Compartment walls and floors in Hastings

For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. The 2 miles around Hastings include eight care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

Hotels such as Eagle House Hotel, 0.9 miles to the south of Hastings, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. On a site such as York Road Business Centre, which lies west of Hastings, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Hastings is in East Sussex. We send applicators to Hastings for service penetrations. Our East Sussex coverage takes in 308 places, from busy centres to rural villages. For work in that direction, see our Brighton page.

Anyone looking for fire stopping in TN34, TN38, TN37 and TN35 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on London Road, Church Road and Upper Church Road are within our area for service penetrations. Hastings sits on or close to the A21 and A28, useful when we plan access and materials. If your building is just outside Hastings, we cover Silverhill (1 mile west), Blacklands (1 mile east), St Helen's (1 mile north-east), Hollington (1 mile north-west) and St Leonards (1 mile south-west). Bigger towns within reach include Eastbourne (13 miles south-west), Bexhill-on-Sea (4 miles west), Hailsham (13 miles west), Polegate (14 miles west), Old Town (15 miles south-west) and Heathfield (15 miles north-west). Hastings ranks among the main centres of East Sussex, with offices, shops, schools and other public and commercial buildings, and we cover them all.

What the job involves on each surface

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

What we seal

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

FAQs: Hastings

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hastings?

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.

Do you take on work at healthcare sites like Conquest Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

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.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • The size and state of each joint
  • Phasing around occupants
  • Removal of failed or old sealant
  • Any access equipment needed

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

However big the job, the same details help:

  • Any specification or named product
  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height
  • Whether an asbestos survey exists
