About our fire stopping in Branchton

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about fire sealant pulled out of the opening and damaged fire seals in risers and voids, on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors. For commercial sealant work in Branchton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places such as Branchton, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Leave it or put it right?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • Constructionline member for supplier checks
  • 12-month guarantee on workmanship
  • Over 20 years of commercial sealing
  • Specification-led, product-correct work

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Branchton, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in

Branchton: questions and answers

Which Scottish guidance covers penetration seals in Branchton?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Can you work around term dates at a campus such as West College Scotland - Greenock Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

Doing it in-house

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.

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

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Reviewing a building’s overall fire safety
  • Issuing fire ratings or certificates for seals
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Quoting for work in Branchton

To price the job, we consider:

  • Phasing around occupants
  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

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
  • The asbestos register, for older buildings
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Fire-rated sealing for Branchton buildings

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, and products should be tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

In a retail centre such as Oak Mall (2 miles north-east of Branchton), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Wherever services are added at a hospital such as Inverclyde Royal Hospital (to the north of Branchton) the compartment line has to be made good with the specified product.

Branchton is about 1 mile west of Greenock, in Inverclyde. Across the PA16 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 19 places in Inverclyde, from busy centres to rural villages. For work in that direction, see our Glasgow page.

Postcode districts covered here: PA16 and PA19. For a building on Ayr Lane, Essex Road and Henge Road or nearby, send details and we’ll quote for service penetrations. You’ll find Branchton on or near the A78. We also cover Braeside (1 mile west), Gourock (1 mile north), Ashton (1 mile north-west), Midton (1 mile north-west) and Trumpethill (2 miles north-west). Nearby towns on our patch include Port Glasgow (5 miles east), Cartsdyke (3 miles east), Kilmacolm (8 miles south-east), Mid Auchinleck (6 miles east), Bogston (4 miles east) and Bardrainney (6 miles east).

Signs you need fire stopping in Branchton

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

What tends to prompt an enquiry:

  • Seals disturbed by maintenance and left open
  • Unsealed openings around new pipes and cables
  • Penetration schedules that need working through
  • Fire sealant pulled out of the opening

For a school such as Inverclyde Academy, penetration sealing fits best at the end of the summer works.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will failed sealant be removed rather than covered?
