Fire rated sealant for homes and businesses in Preston
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We work on pipe & cable gaps, service penetrations and linear gaps, and people most often call us about fire seals that have cracked with movement and gaps flagged on a fire risk assessment.
Work in a place like Preston is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
Every job is covered by a one-year guarantee, wherever you are in the Scottish Borders.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check whether a sealant can be painted before decorating over it
- Keep pictures of seals that will be hidden
- Make resealing part of every contractor’s brief
- Never patch a fire seal with standard sealant
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Fire rated sealant around Preston
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we do not certify buildings or carry out fire risk assessments.
For buildings such as Preston Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Why it’s worth doing now in Preston
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. In a place like Preston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

What affects the cost of fire rated sealant
The price is agreed before any work begins. It takes into account:
- Any mould that needs treating
- How many areas need sealing
- Any working-time requirements on site
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
To help us quote quickly, let us know:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Preston may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Mention any tricky access

Advice
Your questions about fire rated sealant in Preston
Can you do fire rated sealant in Preston?
Yes, Preston is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Do you cover smaller places like Preston?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Can you match the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
What does intumescent mean?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we are called out for in Preston
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.
It’s worth asking for a quote if you see:
- Joints picked up in a fire-stopping survey
- Unsealed gaps where pipes and cables go through a wall
- Fire stopping disturbed by later work
- Fire seals that have cracked with movement
Around Preston, as everywhere, fire rated sealant is only as good as the preparation behind it.
What your quote should include
- Whether they seal over old material or remove it
- Is VAT in the price?
- Whether the sealant suits the joint
- How the colour is chosen
