Fire stopping for businesses in Cathkin

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

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How we handle fire stopping in Cathkin

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and fire stopping installed outside its tested range, across linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations. A specialist sealant contractor works differently from a general builder: in Cathkin, that means joint design, primers and backing rod as standard.

Refurbishments in small hotels, schools and care homes around places like Cathkin can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Record which product was used where
  • Check risers and ceiling voids after each round of works
  • Report damaged or disturbed seals as soon as they’re spotted
  • Leave fire sealant to cure fully before covering it

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match.

Your questions answered

Can work at a site such as University of Strathclyde fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you take on work at healthcare sites like Belvidere Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you seal openings left by new services?

Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals, and we reseal them to the specified detail.

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, and bigger or more complex jobs typically get a visit.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

Signs you need fire stopping in Cathkin

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.

Look out for the following:

  • Fire-stopping items raised at inspection or handover
  • Fire sealant pulled out of the opening
  • Hidden openings found during inspections
  • Damaged fire seals in risers and voids

In a hotel such as Burnside Hotel, 0.9 miles to the north of Cathkin, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Which product they’ll use, and why it suits the joint
  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Fire stopping in Cathkin: the local picture

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, using products tested for the way they’re used. Where fire-rated sealant is specified, that’s what we install, to the tested detail. Cathkin has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

Large healthcare estates like Belvidere Hospital, 2.8 miles north of Cathkin, change their services often, so penetration seals are worth checking after M&E work. Schools such as Fernhill School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Cathkin is about 2 miles south-west of Cambuslang, in South Lanarkshire. We cover Cathkin, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Cathkin is one of 134 places we cover in South Lanarkshire.

We take on service penetrations across the G73 postcode area, whatever the building. Among the streets we cover are Menteith Place, Duror Road and Cathkin Gate. Just outside Cathkin, we also work in Springhall (1 mile north), Whitlawburn (1 mile north-east), Burnside (1 mile north), Kirkhill (1 mile north-east) and Eastfield (1 mile north). A short drive away, we cover East Kilbride (3 miles south), Hamilton (6 miles south-east), Uddingston (5 miles east), Blantyre (4 miles east), Larkhall (10 miles south-east) and Carluke (15 miles east).

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

What happens if it’s left?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Renewing every failing joint on one visit is the sensible approach for a place like Cathkin. Photos of each area help us quote the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building near Cathkin, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We read the specification, drawings or penetration schedule you send.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Arrange parking or a loading space
