Fire stopping for commercial buildings in Harthill
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. So our job is to reproduce that arrangement faithfully. Most enquiries involve seals disturbed by maintenance and left open and fire-rated sealant that has cracked or shrunk back, across joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers. Facilities teams, main contractors and managing agents in Harthill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a building near Harthill, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photographs of the openings, with sizes if you have them.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Service penetrations in Harthill 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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.
On estates like Harthill Industrial Estate, 0.6 miles west of Harthill, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

When to call us in Harthill
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
It’s worth sending us details if you spot any of the following:
- Fire seals cut back for extra cables and never reinstated
- Seals that don’t match their tested detail
- Unsealed openings around new pipes and cables
- Fire sealant pulled out of the opening
For a hospital such as Tippethill Hospital, which lies north-east of Harthill, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Why act early in Harthill
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Renewing every failing joint on one visit is the sensible approach for a place like Harthill. Send photos and we’ll quote for everything together.
Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Questions we’re asked in Harthill
Would you work within a site like Tippethill Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Harthill Industrial Estate, by Harthill?
Yes. Our area takes in Harthill and its surroundings, with estates and business parks such as Harthill Industrial Estate included. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
General trades versus a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
