Fire stopping for Thakeham sites

About our fire stopping in Thakeham

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Thakeham and nearby. Site teams most often ask us about builders’ foam or ordinary silicone in compartment walls and hidden openings found during inspections, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. Whoever orders the work in Thakeham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Thakeham, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Do you need fire stopping in Thakeham?

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.

Any of the following is a good reason to get the joints checked over:

  • Service penetrations left open after M&E works
  • Penetration schedules that need working through
  • Open linear gaps along the top of fire-resisting walls
  • Seals that don’t match their tested detail

Holiday works at schools like Rydon Community College often leave service openings to seal before pupils return.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Their public liability cover
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Compartment walls and floors in Thakeham

At about 41 miles from central London, Thakeham is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. 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.

In a building such as The Parish Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. Office fit-outs on sites such as Crays Court (business park), 0.5 miles to the north-east of Thakeham, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Thakeham is about 8 miles north of Worthing, in West Sussex. If you are looking for fire stopping in Thakeham, we can help, as we do across West Sussex. 373 places across West Sussex fall within our area, Thakeham among them. Brighton is covered too, some 15 miles away.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Signing off or certifying a building’s fire stopping
  • Deciding what a wall or floor needs, which belongs to the designer
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

Leave it or put it right?

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Older rural buildings around Thakeham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

  • Health and safety: CHAS accredited
  • Constructionline member
  • Failed material removed, not covered up
  • CSCS-carded applicators

See how commercial sealant jobs are priced and our accreditations.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Smaller jobs around Thakeham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Send any specification or drawings in advance
  • Send your site hours and access windows
  • Tell staff and tenants when we will be in

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Advice

Questions about Thakeham

Is Thakeham too far out for you?

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.

Do you seal service penetrations in hotels around Thakeham?

Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

How long does a job like this take?

It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Is the work guaranteed?

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

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Induction, permit and paperwork requirements
  • Access and working height
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants

Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • Your programme or deadline
  • The type of building and who uses it

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.
