Fire stopping near Plocrapool

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

After the work

Regular inspection catches problems early. Specifically:

  • Arrange inspection before areas are covered up
  • Agree the fire-stopping specification before services go in
  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Fire stopping in Plocrapool, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. If you are dealing with hidden openings found during inspections and penetration schedules that need working through, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Plocrapool it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Plocrapool is planned so every penetration is sealed on one trip. Send the specification and photos of the openings, with sizes if you have them.

A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we’ll come back to it.

What the job involves on each surface

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Whether the work must be split into stages
  • Joint width, depth and condition
  • How much existing material needs removing
  • Travel to remote or island sites

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

However big the job, these details speed things up:

  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or email the details over.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Fire risk assessments, a job for a competent assessor
  • Writing the fire-stopping specification
  • Approving the work on behalf of building control

If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Tell us who will meet us and how to get in at your building near Plocrapool. We will confirm the plan with the fixed quote.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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.

Preparing the site

  • Point out parking and an unloading spot
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need

Common questions from Plocrapool clients

Is Plocrapool inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Plocrapool included. We group island work where we can and plan around the crossings.

How do Scotland’s building standards affect fire-rated sealant in Plocrapool?

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.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What do you charge?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Service penetrations in Plocrapool buildings

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 proprietary products, intumescent ones included, tested for their end use. We install fire-rated sealant to that tested detail where it is specified. For an island location such as Plocrapool, work is planned around ferry crossings and the weather. The specification and photographs of each penetration let us bring the right products first time.

Around Plocrapool, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product. For any site around Plocrapool, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
