How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
About our fire stopping in Gremista
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to 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. The enquiries we see most involve fire-stopping items raised at inspection or handover and head-of-wall gaps with no fire seal, across pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Gremista tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Hotels and care homes around smaller places like Gremista often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building near Gremista, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Send your site hours and access windows
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work

Related advice
What we’re called out for in Gremista
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Things that usually lead to an enquiry:
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
- Snag lists that include open service penetrations
- Damaged fire seals in risers and voids
For a unit at a site such as Lower Black Hill Industrial Estate, which lies south-west of Gremista, new power or data runs between office and warehouse can breach a compartment wall.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Compartment walls and floors in Gremista
Being on an island, Gremista means planning around ferry times as well as the weather. We need the specification and a count of penetrations before we sail. Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, with proprietary products, intumescent ones included, tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.
Holiday works at schools like Anderson High School often leave service openings to seal before pupils return. Theatres, wards and plant rooms at sites like Montfield Hospital (1.2 miles south of Gremista) all have compartment walls crossed by services.

FAQs: Gremista
Will you travel to Gremista on the island?
Yes. Islands are part of our area, Gremista included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Do you cover business parks and estates near Gremista, such as Lower Black Hill Industrial Estate?
Yes. Our area takes in Gremista and its surroundings, with estates and business parks such as Lower Black Hill Industrial Estate included. Photos and a short description are enough for a first look.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we’re not the right fit for that package.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When is resealing likely to be due?
Nobody can honestly give a figure in years, 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.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
