Fire stopping for Slinfold sites

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

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Slinfold can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Agree which areas must stay open
  • Let us know about inductions and permits
  • Warn occupants and staff about the work

About our fire stopping in Slinfold

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Slinfold and nearby. The enquiries we see most involve fire sealant pulled out of the opening and unsealed penetrations discovered above suspended ceilings, on cable penetrations, pipe penetrations and service gaps in risers. A single leaking joint is often how a building in Slinfold first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A job near Slinfold is usually planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Penetration seals near Slinfold

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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Several hotels sit less than 2 miles from Slinfold. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

In a retail centre such as Broadbridge Retail Park, 2.1 miles to the east of Slinfold, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. At a healthcare site like Horsham Hospital, 3.5 miles east of Slinfold, new services through compartment walls are a constant, and each needs the specified seal.

Slinfold is about 4 miles west of Horsham, in West Sussex. Across the RH13 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 373 places across West Sussex fall within our area, including Slinfold. There’s a separate page for Brighton, roughly 20 miles from Slinfold.

Signs you need fire stopping in Slinfold

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Typical triggers for a call:

  • Snag lists that include open service penetrations
  • Unsealed penetrations discovered above suspended ceilings
  • Improvised or mixed-product fire seals
  • Open linear gaps along the top of fire-resisting walls

Older community buildings such as The Parish Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Our contractor checklist

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Why it’s worth doing now in Slinfold

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Slinfold, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Slinfold: questions and answers

Can you seal around new services in a hotel near Slinfold?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

Can you work on a hospital site such as Horsham Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Cost factors for service penetrations

To price the job, we consider:

  • The product specified
  • The size and state of each joint
  • How much existing material needs removing
  • Induction, permit and paperwork requirements

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

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • Any specification or named product
  • The type of building and who uses it
  • Any dates the work must fit around

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email the details over.
