Fire rated sealant in Carstairs, done properly
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We’re often asked to deal with gaps flagged on a fire risk assessment and fire stopping disturbed by later work, on flats & HMOs, linear gaps and service penetrations.
Work in a place like Carstairs is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.

- We hand over a list of locations and products for your files.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Are the rules for fire-rated sealant different in Scotland?
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’s how we fit it. We don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Do you certify the fire stopping?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you work in flats, HMOs and commercial buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
Will you assess my building’s fire safety?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Are you fully insured?
Yes, we’re fully insured.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Walls or floors that weren’t built to resist fire
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Access and height
Homes and businesses are quoted the same way: 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 explain what it covers.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Do not paint over fire sealant until it has cured
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
- Photograph sealed gaps before they’re covered up
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
How the job changes by surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
Landlord and commercial work in Carstairs
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
