External Mastic in Kirkoswald
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Kirkoswald. Fully insured, ARBOMaster approved and guaranteed for a year.
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
External mastic in Kirkoswald
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you have failed sealant between panels on a façade and movement joints with cracked, split or missing sealant, we can put it right, on concrete & block, render & cladding joints and brickwork movement joints alike.
External sealant needs dry surfaces, so outdoor work around Kirkoswald is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Other services in Kirkoswald
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Common questions in Kirkoswald
I let a flat near Maybole station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Does living near the coast affect external mastic in Kirkoswald?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Kirkoswald, along with the rest of our area.
How long will you be here?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. We will confirm how long when we quote.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Why act early in Kirkoswald
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In an older home around Kirkoswald, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

What we can’t put right
We won’t take on work that won’t last, so these are the limits:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
External mastic in Kirkoswald: local notes
Kirkoswald is within about 2 miles of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In the older streets around Old Parish Church and Graveyard, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Maybole station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. 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.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Move anything stored near the joints
