Fire stopping in Halfway

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Fire stopping in Halfway, done properly

A fire-rated sealant is only one part of a tested system: 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’re dealing with fire sealant pulled out of the opening and fire-stopping items raised at inspection or handover, we can help. A specialist sealant contractor works differently from a general builder: in Halfway, that means joint design, primers and backing rod as standard.

Large city estates in Scotland, from universities to hospitals and offices, are re-serviced constantly, and each new run of cable or pipe through a compartment wall needs sealing. Intumescent sealant goes in where the specification calls for it, with backing and depth as tested.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

How the job changes by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. For premises in Halfway, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Move anything stored against the joints
  • Point out any areas we must not close
  • Let building users know which areas are affected

Ask for a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Related advice

Keeping the joints sound

Once the work is signed off, these steps help:

  • Look above ceilings when tiles are lifted for other jobs
  • File the specified details where the next contractor can find them
  • Agree the fire-stopping specification before services go in
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.

Do you need fire stopping in Halfway?

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

It’s worth sending us details if you spot any of the following:

  • Openings found when ceilings come down for a refit
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping
  • Fire stopping installed outside its tested range

Hospital estates such as The Queen Elizabeth University Hospital Campus (to the north of Halfway) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Choosing a commercial sealant contractor

What sets the cost

These are the things that shape the price:

  • How accessible the joints are
  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Working within restricted access windows

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

However big the job, these details speed things up:

  • The type of building and who uses it
  • The postcode of the building
  • The product your specification calls for
  • The asbestos register, for older buildings

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or send details through our quote form to discuss it first.

Your questions answered

Do you work on fire-rated sealing in hotels in Halfway?

Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Can you work on a hospital site such as The Queen Elizabeth University Hospital Campus?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Service penetrations in Halfway buildings

Two care or nursing homes sit less than 2 miles from Halfway. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified. A 2-mile radius around Halfway takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Colleges such as Glasgow Clyde College - Cardonald Campus (to the south of Halfway) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Industrial units on estates such as Craigton Industrial Estate, less than half a mile to the north of Halfway, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Halfway is about 2 miles south-west of Yorkhill, in Glasgow. We cover commercial sites throughout Halfway, whether it’s a single job or part of a planned programme. Across Glasgow, 171 places are covered, Halfway among them.

Business premises anywhere in G52, G51 and G53 are within our area. Among the streets we cover are Morar Road, Clunie Road and Sunart Road. Access to Halfway is via the A761 among other routes, so getting applicators and materials to site is simple. Just outside Halfway, we also work in Craigton (1 mile north-east), Mosspark (1 mile south-east), Nethercraigs (1 mile south), Drumoyne (1 mile north) and Corkerhill (1 mile south). Bigger towns within reach include Hillhead (3 miles north-east), Dowanhill (3 miles north-east), Woodlands (3 miles north-east), Woodside (3 miles north-east), North Kelvinside (3 miles north-east) and Garnethill (3 miles north-east).
