How we handle fire rated sealant in Bonnyrigg
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you have standard silicone or caulk in a fire-stopping gap and open gaps behind door architraves, we can put it right, on service penetrations, linear gaps and plasterboard & masonry alike.
In a Scottish town like Bonnyrigg, commercial work can mean offices, shops, schools, hotels or care homes, all with washroom, kitchen and fire-rated joints to look after.
Our work is backed for twelve months.

How we quote for fire rated sealant
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Any working-time requirements on site
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Photos by email, if that’s easy
- The type of property
- Access, such as stairs, a lift or height

Workplaces and buildings in Bonnyrigg
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments.
Managing a site like Lasswade High School Centre? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Bonnyrigg Parish Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Different surfaces, different methods
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product.
Why it’s worth doing now in Bonnyrigg
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Private landlords in a town like Bonnyrigg must keep homes wind and watertight under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Common problems we fix in Bonnyrigg
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
Most people get in touch after spotting something like this:
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Seals cut through by electricians, plumbers or data installers
- Ordinary sealant used where a fire-rated product was needed
For landlords with property near Eskbank station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before you book
- What preparation is included
- What the cure time is
- What guarantee comes with the work
- Who does the work, and how experienced they are
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. A visit in Bonnyrigg needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
