External mastic in Rankinston
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Common call-outs are for old sealant gone brittle and cracked and damp patches traced to an open external joint, on joints between brick and frames, render & cladding joints and brickwork movement joints.
In and around a place like Rankinston, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Quotes for external mastic in Rankinston
Call for a quick quote. What matters most is:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The number and length of the joints
- Any working-time requirements on site
Leaving a failed joint generally 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 and we’ll give you an honest view and a quote.
What we need to know
When you call or email, it’s useful to know:
- The rough size of the job
- If someone has resealed it before
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
What we are called out for in Rankinston
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
Around Rankinston, as everywhere, external mastic is only as good as the preparation behind it.
Questions to ask before you book
- Which colour the sealant will be
- Whether they seal over old material or remove it
- Who turns up on the day
- What preparation is included
Keeping the joints in good condition
After the cure time, these simple habits help:
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Rankinston questions
Is Rankinston within the area you cover?
Yes. Rankinston is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with external mastic in Rankinston?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall. If it has already been filled, we can generally cut it out and reseal it.
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 so it does not stand out.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Should I try it myself first?
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. All the old material has to come out first.
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.
How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Around Rankinston, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- 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
- Mention any tricky access
- Tell us about any water getting in

Walls and rooflines in Rankinston
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Whether the job is in Rankinston itself or nearby, the right material for each joint matters as much as a neat finish.

Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
