Fire stopping in Keyhead
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Keyhead is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings

Fire stopping for commercial buildings in Keyhead
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. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, linear gaps at wall heads and pipe penetrations, and the failures we are asked to look at most are unsealed openings around new pipes and cables and seals disturbed by maintenance and left open. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Keyhead, that means joint design, primers and backing rod as standard.
For a building near Keyhead, 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 our installation lets you down in that time, we return and fix it.

Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Keyhead before they leak.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Service penetrations in Keyhead buildings
Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail.
Wherever the building is near Keyhead, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified. Around Keyhead, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

What the job involves on each surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, with no gaps along the run.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Keyhead: questions and answers
Is Keyhead too small for you to travel to?
Not at all. Keyhead is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Will you design a fire-stopping scheme for our building in Keyhead?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can staff carry on working while you are here?
Typically, yes. Phased work can be planned so areas stay in use.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Put resealing into every M&E and fit-out package
- Arrange inspection before areas are covered up
- Don’t let anyone top up a fire seal with the wrong product
- Leave fire sealant to cure fully before covering it
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.
Cost factors for service penetrations
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- Backing rod, priming and other preparation
- The total length or number of joints
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- The type of building and who uses it
- Specification clauses that apply
- Clear photos of the problem areas
- Any dates the work must fit around
