External mastic for homes and businesses in Springholm
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall. We work on copings & trims, concrete & block and joints between brick and frames, and common reasons people get in touch are joints pointed up with cement by mistake and leaking joints around cladding and façade panels.
Outside joints can only be sealed when they’re dry, so work in Springholm depends on the weather. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job.

When it isn’t the sealant
It helps to know what we cannot do too:
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

Common questions in Springholm
Is Springholm in your area for external mastic?
Yes. We work across all of Scotland, and Springholm is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is Springholm within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Common problems we fix in Springholm
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Panel joints letting water in
Around Springholm, as everywhere, external mastic is only as good as the preparation behind it.
What to look for in a quote
- How much experience the applicator has
- Which sealant they’ll use, and why
- Whether you can choose the colour
- How long the guarantee is
Why it’s worth doing now in Springholm
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Colour agreed with you before work begins
- Trusted Arbo and Everbuild sealants
- White, clear, grey or coloured to suit, where the product allows
- Tidy, careful work

External mastic in Springholm: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For jobs in and around Springholm, choosing the right material for each joint is as important as a tidy finish.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Outdoor work around Springholm depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
