External mastic for homes and businesses in Fishcross
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant, across joints between brick and frames, concrete & block and façade panels.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In an older home around Fishcross, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

What we are called out for in Fishcross
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch after spotting one of these:
- Plants rooting in failed movement joints
- Old sealant gone brittle and cracked
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
Managing a site like Alva Academy? Then its movement joints, gutters and trims need looking after like any other building’s.

Landlord and commercial work in Fishcross
Letting agents often deal with us directly. Tell us the address, the job and how access works.
For anyone letting property in or around Fishcross, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we’ve said otherwise
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Outside joints around Fishcross
Fishcross is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Letting a property close to Alloa station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Advice
Surface by surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
