Fire stopping for businesses in Unthank

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

After the work

Regular inspection catches problems early. Specifically:

  • Put resealing into every M&E and fit-out package
  • Report damaged or disturbed seals as soon as they’re spotted
  • Arrange inspection before areas are covered up
  • Ask the designer to confirm details early on refits

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.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

How we handle fire stopping in Unthank

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you’re dealing with improvised or mixed-product fire seals and openings found when ceilings come down for a refit, we can help, on service gaps in risers, joints between fire-resisting walls and floors and cable penetrations alike. Whoever orders the work in Unthank, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a building near Unthank, we plan fire-rated sealing so it’s finished in one visit where possible. Photos of the gaps, the services and the wall or floor type help us bring the right products.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Unthank

Can you take on a job at a hospital such as Stracathro Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

How do the Scottish rules apply to fire-rated sealing in Unthank?

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 will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What site paperwork can you supply?

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

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Common problems we fix in Unthank

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position, so it has to come out.

Typical triggers for a call:

  • Snag lists that include open service penetrations
  • Seals disturbed by maintenance and left open
  • Improvised or mixed-product fire seals
  • Head-of-wall gaps with no fire seal

In a hotel such as Northern Hotel, 0.6 miles south of Unthank, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • How they’ll work around occupants
  • Their pre-qualification and accreditations
  • Their public liability cover

Choosing a commercial sealant contractor

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Working within restricted access windows
  • Access and working height
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • Your programme or deadline
  • Any specification or named product
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists

To get a fixed quote, give us a call on 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.

Different surfaces, different methods

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.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building near Unthank, directions, keys and a contact on the day are worth sorting early. 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. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Send your site hours and access windows

Where services cross fire walls in Unthank

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

In a building such as West and St Columba's Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. In a school such as Brechin High School, fire-rated sealant goes in around service penetrations where it is specified.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Fire doors, dampers or other fire safety equipment
  • Walls or floors that aren’t fire-resisting to begin with
  • Deciding what a wall or floor needs, which belongs to the designer

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

  • Service gaps in risers
  • Cable penetrations
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
