Fire stopping in Hardgate

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Some joints are best left to specialists: 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.

Fire stopping for commercial buildings in Hardgate

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. 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, not a rule of thumb. Most enquiries involve damaged fire seals in risers and voids and openings found when ceilings come down for a refit, on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hardgate is the same: the right product in a properly prepared joint.

In smaller Scottish places like Hardgate, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Surface by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Questions about Hardgate

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

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.

Do you decide the fire-stopping details for buildings in Hardgate?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can staff carry on working while you are here?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you seal on top of existing sealant?

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

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

When to call us in Hardgate

Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access normally bring them to light.

Common reasons buildings call us in:

  • Service penetrations left open after M&E works
  • Old intumescent sealant that has split away
  • Expanding foam used as fire stopping
  • Fire seals cut back for extra cables and never reinstated

Around Hardgate, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Our contractor checklist

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Issuing fire ratings or certificates for seals
  • Gaps in walls that were never built as compartment walls
  • Writing the fire-stopping specification

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

Where we work in Hardgate

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

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Tell us who will meet us and how to get in at your building near Hardgate. That goes into the plan alongside the quote.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Point out parking and an unloading spot
  • Send your site hours and access windows
  • Move anything stored against the joints

Fire stopping around Hardgate: what changes locally

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. We install what’s specified, to the product’s tested detail.

In a building such as Urr Parish Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
