External mastic in Ballantrae
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with rain getting behind render or cladding at a joint and brick movement joints where the sealant has split, we can help, on copings & trims, façade panels and concrete & block alike.
External sealant needs dry surfaces, so outdoor work around Ballantrae is planned around the weather. Tell us how to reach each wall, gutter and roofline.
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.

FAQs for Ballantrae
Do you cover smaller places like Ballantrae?

Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Do you work at height?
It depends on the building. Send us pictures and a rough idea of the height, and we will confirm what access is needed.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Keep children and pets away from the work area

What sealant work can’t fix
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

What external mastic looks like in Ballantrae
Ballantrae is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
Around Ballantrae, as everywhere, external mastic is only as good as the preparation behind it.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
When to call us in Ballantrae
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
In the older streets around Ballantrae Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Before booking anyone
- Is the old sealant removed completely?
- Are they insured?
- Is VAT in the price?
- When the joint can take water or movement
Looking after it afterwards
So the new joints stay in good condition:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
