Fire stopping for commercial buildings in Croy

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve fire-stopping items raised at inspection or handover and openings left by services added after handover, across pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. A specialist sealant contractor works differently from a general builder: in Croy, that means joint design, primers and backing rod as standard.

Refurbishments in small hotels, schools and care homes around places like Croy can leave gaps around new services. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Cost factors for service penetrations

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • Travel to remote or island sites

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • The postcode of the building
  • Access details, including height
  • The asbestos register, for older buildings
  • What the building is and how it’s used

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.

Fire-rated sealing for Croy 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, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For a hospital such as Victoria Memorial Cottage Hospital (1.7 miles north-west of Croy), penetration sealing is normally phased ward by ward, with infection-control rules agreed first. At a college such as New College Lanarkshire - Cumbernauld Campus, 2.2 miles south-east of Croy, checking penetration seals after summer M&E works is good practice. For a school such as Our Lady's High, penetration sealing fits best at the end of the summer works.

Croy is about 2 miles west of Cumbernauld, in North Lanarkshire.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

On site: what to expect

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Croy are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Confirm the product named in the specification

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Include service cupboards in routine inspections
  • File the specified details where the next contractor can find them
  • Get seals inspected before ceilings and boxing close
  • Foam or ordinary sealant is never a fire-seal repair

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Your questions answered

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

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is a smaller place like Croy outside your area?

No. Small places get the same service as large ones. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months on every job.

How much does the work cost?

Each job is quoted on its own details. For yours, call the office on 01277 525 020 or send details through our quote form.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, specified by your designer.

What the job involves on each surface

Metal pipes

Heat travels along metal pipework, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.
