Do you need external mastic in Kilmarnock?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
Homes close to Henderson Church Of Scotland include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

How we handle external mastic in Kilmarnock
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on façade panels, joints between brick and frames and brickwork movement joints, and the jobs we see most are damp patches traced to an open external joint and sealant pulling away from one side of the joint.
Scottish weather is hard on outside joints, and a town like Kilmarnock gets its share of wind and rain. A gap in a gutter joint, fascia trim or wall joint soon lets damp in.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why deal with it now?
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. If you live in a flat in Kilmarnock, failed sealant can send water to the neighbours below, and that is much harder to put right.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Walls and rooflines in Kilmarnock
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Kilmarnock is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
If you look after a building such as Kilmarnock Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Kilmarnock station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.

Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. A visit in Kilmarnock needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
