How we handle external mastic in Broomhouse
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 failed seals between different materials and weeds or debris growing in open joints, across brickwork movement joints, joints between brick and frames and render & cladding joints.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Broomhouse, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

When to call us in Broomhouse
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
For site and facilities teams at buildings such as Forrester High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- How long to leave it before use
- What preparation is included
- Whether all the old sealant comes out first
- How long the guarantee is
The process
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a city area like Broomhouse, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Outside joints around Broomhouse
With historic houses such as Caroline Park (about 4 miles north-east) nearby, there’s older building stock in the area around Broomhouse as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to St Joseph's RC Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Kingsknowe station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What else we do in Broomhouse
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid pressure-washing directly into sealant joints
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
FAQs for Broomhouse
How is work on the outside of a tenement in Broomhouse normally arranged?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Do you cover Broomhouse for external mastic?
Yes. Our work covers the whole of Scotland, and Broomhouse is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Honest limits
A few problems are outside what sealant work can do:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
What we seal
- Render & cladding joints
- Façade panels
