How we handle fire rated sealant in Castlemilk
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, door frames and service penetrations, and people most often call us about new service routes left unsealed after building work and open gaps behind door architraves.
Hotels, serviced apartments and student accommodation in Scotland’s cities need their bathrooms kept in order between guests, so work in Castlemilk can be planned room by room, and out of hours where needed.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Castlemilk questions
Do Scottish building rules affect fire-rated sealant work in Castlemilk?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Do you work for landlords with property near Croftfoot station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Do you carry out fire risk assessments?
No. We work from the specification you give us and install to the manufacturer’s details.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will we have a record of what was sealed?
Yes. Every gap we seal is listed with the product used, so you have it on file.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Make resealing part of every contractor’s brief
- Get damaged fire seals looked at promptly
- File the fire-stopping record where your assessor can find it
- Include hidden areas like risers in routine checks
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
What happens on the day
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. In a city area like Castlemilk, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Preparing for the visit
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Related advice
Do you need fire rated sealant in Castlemilk?
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Common reasons people contact us are:
- Ordinary sealant used where a fire-rated product was needed
- Open joints along the top of partitions
- Open gaps behind door architraves
- Unsealed gaps where pipes and cables go through a wall
If you let a flat or house near Croftfoot station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the job changes by surface
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist.
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 sealant bonds.
Landlords, agents and businesses in Castlemilk
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too in Castlemilk and across Glasgow. Several sites can be quoted together, and we’re fully insured.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
