External mastic in Muirhouse
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 a rigid filler would soon crack. Common call-outs are for panel joints letting water in and joints where the bead has come unstuck, on concrete & block, render & cladding joints and copings & trims.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.

Muirhouse buildings and the weather
Historic houses like Cambusnethan House (about 1.5 miles south-east) are a reminder that the area around Muirhouse has older buildings as well as new. Where a home is older, 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.
Managing a site like Our Lady's High School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Shieldmuir station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St Patrick's R.C. Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Outdoor work around Muirhouse depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Advice
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Why act early in Muirhouse
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. In an older home around Muirhouse, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Muirhouse: your questions answered
Do you cover smaller places like Muirhouse?
Yes. Muirhouse is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Shieldmuir station?
Yes. We work for landlords and agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you use backing rod?
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 joint can move.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
