Common questions from Clydebank clients

Is hospital work, at somewhere like Golden Jubilee National Hospital, something you do?

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.

Which Scottish guidance covers penetration seals in Clydebank?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

How do I request a quote?

About our fire stopping in Clydebank

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and expanding foam used as fire stopping, across linear gaps at wall heads, pipe penetrations and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Clydebank, that means joint design, primers and backing rod as standard.

Fire-rated sealing in Clydebank follows the specification set by the designer: design and sign-off sit with the designer, fire engineer or the local authority verifier, and we install what is specified. Records of the work can be discussed when we quote.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the job changes by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.

Building owners, agents and FMs in Clydebank

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Common problems we fix in Clydebank

Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

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

  • Openings left by services added after handover
  • Builders’ foam or ordinary silicone in compartment walls
  • Head-of-wall gaps with no fire seal
  • Fire seals cut back for extra cables and never reinstated

Theatres, wards and plant rooms at sites like Golden Jubilee National Hospital, 0.9 miles south-west of Clydebank, all have compartment walls crossed by services.

  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Why it’s worth doing now in Clydebank

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. A leaking joint can damage finishes, stock and fittings inside. Putting it right early limits the damage.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What you get with us

  • 12-month guarantee on workmanship
  • Over 20 years of commercial sealing
  • Clear, fixed quotes
  • Specification-led, product-correct work

When to bring in a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Fire stopping around Clydebank: how the place shapes the job

A 2-mile radius around Clydebank takes in a number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with 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, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For a building at a site such as Clydebank Business Park, 0.7 miles to the south of Clydebank, a check of penetration seals after each fit-out is good practice. At a college such as West College Scotland - Clydebank Campus, 1.4 miles south of Clydebank, checking penetration seals after summer M&E works is good practice.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If you manage more than one building in Clydebank, they can be grouped, with one quote. Give us access times for each.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  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.

What we need from you

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Move anything stored against the joints
