Fire stopping for Steinis sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Steinis

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on linear gaps at wall heads, service gaps in risers and cable penetrations, and what we are called in for most is old intumescent sealant that has split away and seals that don’t match their tested detail. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Steinis, that means joint design, primers and backing rod as standard.

Refurbishments in small hotels, schools and care homes around places like Steinis 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why it’s worth doing now in Steinis

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Questions we are asked in Steinis

Do you work on the island where Steinis is?

Yes, Steinis is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

Do you cover business parks and estates near Steinis, such as Parkend Industrial Estate?

Yes. We cover Steinis and the area around it, including industrial estates, business parks and retail parks such as Parkend Industrial Estate. Photos and a short description are enough for a first look.

What if there’s asbestos in the old mastic?

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

Do you work in Scotland as well as England?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Is the work guaranteed?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What do you charge?

We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Common problems we fix in Steinis

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

These are often picked up first by site or facilities staff:

  • Service penetrations left open after M&E works
  • Fire-stopping items raised at inspection or handover
  • Builders’ foam or ordinary silicone in compartment walls
  • Damaged fire seals in risers and voids

Wherever services are added at a hospital such as Western Isles Hospital (to the west of Steinis) the compartment line has to be made good with the specified product.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

Compartments and services around Steinis

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, and products should be tested for their end use. We install what’s specified, to the product’s tested detail. Island jobs, Steinis among them, are planned around the ferry and the forecast. With the specification and photos of the openings, the right fire-rated products travel with us.

For a unit at a site such as Parkend Industrial Estate, 1.2 miles south of Steinis, new power or data runs between office and warehouse can breach a compartment wall.

Steinis is in Na h-Eileanan Siar. Any commercial site in Steinis is covered, whether it’s a single job or part of a planned programme. Steinis is one of 87 places in Na h-Eileanan Siar on our list for service penetrations.

Different surfaces, different methods

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

What sets the cost

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

  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Any specification or named product
  • The site address and postcode
  • Access details, including height
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email drawings and photos.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building near Steinis, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Send your site hours and access windows
  • Tell staff and tenants when we’ll be in
  • Explain the parking and delivery arrangements

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. 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.
