External mastic in Barns of Claverhouse
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. Common call-outs are for rigid filler in a joint that should flex and old sealant gone brittle and cracked, across render & cladding joints, façade panels and brickwork movement joints.
External sealant needs dry surfaces, so outdoor work around Barns of Claverhouse is planned around the weather. Tell us how to reach each wall, gutter and roofline.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Signs you need external mastic in Barns of Claverhouse
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
If you let a flat or house near Dundee station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether all the old sealant comes out first
- Whether you can choose the colour
- Whether the sealant suits the joint
- Whether VAT is included
When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Rising or penetrating damp from elsewhere in the wall
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Why it’s worth doing now in Barns of Claverhouse
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. In a place like Barns of Claverhouse, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
What you get with us
- ARBOMaster approved applicator
- Sanitary silicone with an anti-fungal additive in wet areas
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows

Barns of Claverhouse buildings and the weather
With historic houses such as Camperdown House (about 3.5 miles south-west) nearby, there’s older building stock in the area around Barns of Claverhouse as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For site and facilities teams at buildings such as Baldragon Academy, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Mains Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Your questions about external mastic in Barns of Claverhouse
Will you come out to Barns of Claverhouse?
Yes. Barns of Claverhouse is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Barns of Claverhouse?
Yes. We work across all of Scotland, and Barns of Claverhouse is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
