Fire Rated Sealant in Lanark
Our applicators work in Lanark on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Open gaps behind door architraves
- Open joints along the top of partitions
- Unsealed gaps where pipes and cables go through a wall
What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

Advice
Fire rated sealant in Lanark
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. We work on pipe & cable gaps, door frames and plasterboard & masonry, and people most often call us about gaps flagged on a fire risk assessment and open joints along the top of partitions.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
Big or small, it’s backed by our one-year guarantee.

Questions from Lanark
Do you work for hotels and guest houses in Lanark?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do Scottish building rules affect fire-rated sealant work in Lanark?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you work in Lanark?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Lanark included.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in.
Surface by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
- Report cracked or damaged seals as soon as you notice them
- Do not paint over fire sealant until it has cured
Do not 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.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.
Fire rated sealant around Lanark
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, though we do not certify buildings or do fire risk assessments. Lanark has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Managing a site like Lanark Grammar School? Then fire-stopping around service openings should be restored whenever new services go in.

Signs you need fire rated sealant in Lanark
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
Look out for any of the following:
- Gaps flagged on a fire risk assessment
- Unsealed gaps where pipes and cables go through a wall
- Ordinary sealant used where a fire-rated product was needed
- Door frames with gaps between frame and wall
Letting a property close to Lanark station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Why deal with it now?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. Around Lanark, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
