Fire stopping near East Helmsdale

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Joint width, depth and condition

A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Whether the building will be occupied during the work
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

How we handle fire stopping in East Helmsdale

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have improvised or mixed-product fire seals and head-of-wall gaps with no fire seal, we can help, whatever the surface. Facilities teams, main contractors and managing agents in East Helmsdale tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as East Helmsdale, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Those penetrations are closed with the product the specification names, built up as tested.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common questions from East Helmsdale clients

Can you seal penetrations in a hotel in East Helmsdale after a refit?

Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.

What do Scotland’s building standards say about service penetrations in East Helmsdale?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Should maintenance staff do it?

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

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Large openings beyond what any sealant detail covers
  • Gaps in walls that were never built as compartment walls
  • Signing off or certifying a building’s fire stopping

If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around East Helmsdale, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000

Fire-rated sealing for East Helmsdale buildings

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. The area within 2 miles of East Helmsdale holds several hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

For buildings in and around East Helmsdale, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. For a hotel such as Belgrave Arms Hotel (less than half a mile south of East Helmsdale), penetration seals are worth checking after any refit or services upgrade.

East Helmsdale is about 33 miles south of Thurso, in Highland. Across the KW8 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 256 places in Highland.

Work on service penetrations is covered throughout KW8. Buildings on Sutherland Street, Stafford Street and Trentham Street are within our area. If your building is just outside East Helmsdale, we cover Navidale (1 mile north-east), Berriedale (7 miles north-east), Dalchalm (10 miles south-west), Clynelish (10 miles south-west) and Brora (10 miles south-west). For island and remote sites, we plan travel and materials carefully.

Around East Helmsdale

East Helmsdale has its own railway station: Helmsdale station. Nearby you’ll also find Timespan (less than half a mile west). Open spaces near East Helmsdale include Ord of Caithness.

Why act early in East Helmsdale

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. 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. Resealing early avoids that.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Why us?

  • A fixed quote before work starts
  • Products installed to the manufacturer’s instructions
  • Public liability insurance in place
  • Sealing commercial buildings since 2005

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Brief every trade that openings they make must be sealed
  • Foam or ordinary sealant is never a fire-seal repair
  • Treat an open penetration as a priority repair
  • Ask the designer to confirm details early on refits

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
