How we handle fire stopping in Tangmere

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Tangmere, preparation and product choice get the time they need.

In places the size of Tangmere, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Reviewing a building’s overall fire safety
  • 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 ring 01277 525 020 or email the details over and we will tell you honestly.

Surfaces we seal

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

When to call us in Tangmere

Most open service penetrations are left by later work. 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.

If one of these sounds familiar, it’s time for a closer look:

  • Hidden openings found during inspections
  • Improvised or mixed-product fire seals
  • Unsealed joints where partitions meet the slab
  • Unsealed openings around new pipes and cables

Hotels like The Richmond Arms Hotel (1.4 miles north-west of Tangmere) are refurbished in phases, and each phase can open up compartment walls.

Questions to ask before you appoint anyone

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. What matters most for a job in Tangmere is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  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

  • Make sure the joints can be reached
  • Agree which areas must stay open
  • Point out parking and an unloading spot

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Why it’s worth doing now in Tangmere

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings in places like Tangmere, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

What you get with us

  • Old sealant cut out, never sealed over
  • 12 months’ guarantee on every job
  • Health and safety: CHAS accredited
  • A Constructionline member, so easy to vet

Service penetrations in Tangmere buildings

Two care or nursing homes sit less than 2 miles from Tangmere. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Several hotels sit less than 2 miles from Tangmere. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

On a hospital site such as St Richard's Hospital (2.4 miles west of Tangmere), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Offices at parks like Chichester Business Park., less than half a mile east of Tangmere, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Questions we’re asked in Tangmere

Is Tangmere off your patch?

No. Places such as Tangmere are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Will you plan work around the academic year at somewhere like University of Chichester?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.

Are you insured?

Yes. We’re fully insured, including public liability cover.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is BS 476 being phased out?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.

Can you fire stop behind the services contractors?

Yes. Share the penetration schedule and product details and a fixed quote follows. Work can run area by area behind the M&E trades so areas aren’t left open.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
