Fire stopping across Cessnock

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Looking after the joints

For the best life from the joints:

  • Ask which product is in place before decorating
  • Record which product was used where
  • Don’t let anyone top up a fire seal with the wrong product
  • Report damaged or disturbed seals as soon as they’re spotted

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Fire stopping in Cessnock, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with builders’ foam or ordinary silicone in compartment walls and seals that don’t match their tested detail, we can help. Looking for mastic applicators who cover Cessnock? We have been sealing commercial buildings since 2005.

Under Scotland’s building standards, a service penetration should keep at least the fire resistance duration of the wall or floor it passes through. For a building in Cessnock, specified fire-rated sealant is installed as the maker’s tested detail describes.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control
  • Writing the fire-stopping specification

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.

Joints and surfaces we work on

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

Fire-rated sealing for Cessnock buildings

The 2 miles around Cessnock include three care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified.

Shop fits in centres such as West End Retail Park (to the north-west of Cessnock) can bring new services through fire-resisting walls between units, which then need the specified seal. At a university such as University of Glasgow Gilmorehill Campus, which lies north of Cessnock, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Cessnock is about 1 mile west of Glasgow, in Glasgow. Cessnock sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 171 places in Glasgow, from busy centres to rural villages.

Common questions from Cessnock clients

What do Scotland’s building standards say about service penetrations in Cessnock?

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.

Will you take on work at estates like Academy Office Park, close to Cessnock?

Yes, sites like Academy Office Park are within our area, along with the rest of Cessnock. Send details of the unit and the work through our quote form for a quick quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Can you work while the building is occupied?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How long do sealant joints last?

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 inspection is the best way to catch problems early.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Give us the access times and building rules for your premises in Cessnock, so the work can be phased and areas kept in use.

  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.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Preparing the site

  • Send your site hours and access windows
  • Let building users know which areas are affected
  • Share the asbestos register for older buildings

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

How the quote is worked out

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • The product specified
  • Whether the work must be split into stages

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What we need to price the job

However big the job, the same details help:

  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • The type of building and who uses it

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or email us.

Common problems we fix in Cessnock

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

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

  • Fire sealant pulled out of the opening
  • Open linear gaps along the top of fire-resisting walls
  • Fire stopping installed outside its tested range
  • Builders’ foam or ordinary silicone in compartment walls

Workshops and IT rooms at colleges like City of Glasgow College - Riverside Campus, 1.7 miles to the east of Cessnock, are re-serviced often, leaving penetrations to seal.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • How the existing material will be dealt with
  • Do they follow the manufacturer’s priming guidance?
  • What site paperwork they can supply
