External mastic for homes and businesses in Kilmichael Glassary
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have water getting into walls through failed joints and rigid filler in a joint that should flex, we can help, on joints between brick and frames, concrete & block and façade panels alike.
Outside joints can only be sealed when they’re dry, so work in Kilmichael Glassary depends on the weather. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in Kilmichael Glassary
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Around Kilmichael Glassary, water from a failed joint in an older stone home can soak into timber and plaster.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

How to look after the new joints
Aftercare is simple:
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Avoid pressure-washing directly into sealant joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
Walls and rooflines in Kilmichael Glassary
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. Kilmichael Glassary 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.

Do you need external mastic in Kilmichael Glassary?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Weeds or debris growing in open joints
For an older house near a landmark such as Kilmichael Glassary Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents and landlords in Kilmichael Glassary can book us as well as householders. Sealant work between tenants keeps a property looking cared for.

Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.

That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
