Fire stopping for Polegate sites

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

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. For a site in Polegate, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Agree which areas must stay open
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email drawings and photos.

Fire stopping in Polegate, done properly

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Site teams most often ask us about unsealed joints where partitions meet the slab and openings found when ceilings come down for a refit, on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows. A specialist sealant contractor works differently from a general builder: on jobs in Polegate, preparation and product choice get the time they need.

Around Polegate, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant

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

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on

If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Where we work in Polegate

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

How the quote is worked out

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

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Induction, permit and paperwork requirements

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists
  • Access details, including height

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or use the quote form.

What the job involves on each surface

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Building owners, agents and FMs in Polegate

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

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

Keeping the joints sound

A few simple habits keep the new joints working:

  • Arrange inspection before areas are covered up
  • Settle who seals which penetrations at the start of a project
  • Ask which product is in place before decorating
  • Keep general-purpose fillers away from compartment walls

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there, not months later.

Polegate: questions and answers

Is a smaller place like Polegate outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is a hospital such as Eastbourne District General Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Do the same rules apply to fire stopping in Scotland?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor.

Will you write the fire-stopping specification?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Where services cross fire walls in Polegate

Central London is about 49 miles from Polegate. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Approved Document B is the English guidance that covers fire stopping around 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.

For a site team at a college like East Sussex College Eastbourne, which lies south-east of Polegate, fire-rated sealing is best scheduled after the summer works. Tenant changes at centres like Hampden Park Retail Park (2.4 miles south-east of Polegate) often mean new services through walls between units. For a unit at a site such as Chaucer Industrial Estate, which lies east of Polegate, new power or data runs between office and warehouse can breach a compartment wall.
