About our fire rated sealant in Coulter
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Typical jobs include sealant items on a fire risk assessment action list and cracked or shrunken fire-rated sealant, across plasterboard & masonry, door frames and flats & HMOs.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the quote in Coulter
The quote reflects the job in front of us. We look at:

- How many rooms, windows or areas are involved
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. For a place like Coulter, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Workplaces and buildings in Coulter
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
For buildings such as Culter Parish Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Landlord and commercial work in Coulter
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Leave it or put it right?
Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Common problems we fix in Coulter
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
People generally contact us when they notice one of these:
- Fire seals that have cracked with movement
- Open joints along the top of partitions
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
In and around Coulter, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Your questions about fire rated sealant in Coulter
Will you come out to Coulter?

Is Coulter in your area for fire rated sealant?

Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you work in occupied buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Aftercare tips
So the new joints stay in good condition:
- Store the list of sealed gaps with your building paperwork
- Include fire stopping when you schedule refits
- Check whether a sealant can be painted before decorating over it
- Tell trades working in the building that fire seals must be put back
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
