Fire stopping in Horne

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

Why deal with it now?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. One visit to deal with every failing joint makes more sense than several trips to a place like Horne. Photos of every joint help us quote for the whole job.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why us?

  • One phone line for London, the South East and Scotland
  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over
  • Sealing commercial buildings since 2005

How we handle fire stopping in Horne

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. If you are dealing with damaged fire seals in risers and voids and old intumescent sealant that has split away, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Horne, preparation and product choice get the time they need.

For a smaller site near Horne, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Signs you need fire stopping in Horne

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.

Common reasons buildings call us in:

  • Expanding foam used as fire stopping
  • Fire-stopping items raised at inspection or handover
  • Old intumescent sealant that has split away
  • Improvised or mixed-product fire seals

Office fit-outs on sites such as Hays Bridge Business Park, 0.6 miles east of Horne, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

How to choose a sealant contractor

FAQs: Horne

Is Horne too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you take on work at estates like Hays Bridge Business Park, close to Horne?

Yes. Our area takes in Horne and its surroundings, with estates and business parks such as Hays Bridge Business Park included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

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 everything comes out first.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Horne can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Let us know about inductions and permits
  • Point out parking and an unloading spot

Related advice

Site staff or a sealant specialist?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Service penetrations in Horne buildings

Horne lies roughly 22 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hospital estates such as East Surrey Hospital, 4.2 miles to the north-west of Horne, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Keeping the joints sound

After handover, these steps help:

  • Check risers and ceiling voids after each round of works
  • Report damaged or disturbed seals as soon as they’re spotted
  • File the specified details where the next contractor can find them
  • Leave fire sealant to cure fully before covering it

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

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.
