Why it’s worth doing now in Longside
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. Around Longside, water from a failed joint in an older stone home can soak into timber and plaster.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Fire rated sealant for homes and businesses in Longside
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you’re dealing with open joints along the top of partitions and joints picked up in a fire-stopping survey, we can help, on service penetrations, door frames and flats & HMOs alike.
Work in a place like Longside is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
Our work is backed for twelve months.

Looking after it afterwards
So the new joints stay in good condition:
- Include fire stopping when you schedule refits
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
- Keep general-purpose foam and caulk away from fire-stopping gaps
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Walls or floors that weren’t built to resist fire
- Deciding what fire stopping a building needs
- Certifying a building or signing off its fire safety
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
Surfaces we seal

Longside questions
Is Longside in your area for fire rated sealant?
Yes, Longside is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Longside?
Yes. Longside is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.
Are you insured?
Yes. Mr Mastic is fully insured.
What fire rating will the seal have?
We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it, recording the locations and products.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Commercial buildings in Longside
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments.

Different surfaces, different methods
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.
What happens on the day
There’s no need to move everything out, 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 in most cases. Around Longside, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.

Advice
Do you need fire rated sealant in Longside?
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
Around Longside, as everywhere, fire rated sealant is only as good as the preparation behind it.
What your quote should include
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
- What happens if the job turns out different
- The length of the guarantee
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. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
