Fire stopping for businesses in Bolney

About our fire stopping in Bolney

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 on buildings around Bolney. We work on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we are called in for most is expanding foam used as fire stopping and old intumescent sealant that has split away. One point of contact handles commercial sealant work in Bolney from the first photos to the final walk-round, whether it’s one building or several.

For a smaller site near Bolney, we plan to do all the penetrations in one go, 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.

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

Compartment walls and floors in Bolney

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. Bolney lies roughly 35 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

Halls and meeting rooms at places like St Mary Magdalene's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. Schools such as Bolney CofE Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Bolney is about 4 miles north-west of Burgess Hill, in West Sussex. Commercial clients in Bolney use us for work on service penetrations, as part of our coverage of West Sussex.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Plastic pipes whose detail calls for a collar or wrap
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

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

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Location, for remote and island sites
  • The total length or number of joints
  • Whether the work must be split into stages
  • Access and working height

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send photos by email.

Bolney: questions and answers

Does your area include sites such as Crosspot Industrial Estate, near Bolney?

Yes, sites like Crosspot Industrial Estate are within our area, along with the rest of Bolney. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

How does the move away from BS 476 affect penetration seals in Bolney?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you work in Bolney?

Yes. Bolney is in our area. To discuss a job, phone 01277 525 020 or send details through our quote form.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Flag new cables with no seal around them
  • Look above ceilings when tiles are lifted for other jobs
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask the designer to confirm details early on refits

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

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

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Bolney may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Let building users know which areas are affected

Related advice

When to call us in Bolney

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Site and facilities staff are often the first to spot these:

  • Old intumescent sealant that has split away
  • Fire seals cut back for extra cables and never reinstated
  • Expanding foam used as fire stopping
  • Fire stopping installed outside its tested range

Large healthcare estates like The Dene Hospital (to the south-east of Bolney) change their services often, so penetration seals are worth checking after M&E work.

  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?
