External mastic for homes and businesses in Kirkintilloch
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for joints pointed up with cement by mistake and failed seals between different materials, on façade panels, copings & trims and concrete & block.
Harled walls are common in Scottish towns like Kirkintilloch, and sealing where harling meets a frame or pipe takes a sealant that can grip a rough surface. Gutters and fascias here take plenty of Scottish weather too.
Each job carries a 12-month guarantee, large or small.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation. A visit in Kirkintilloch needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Why act early in Kirkintilloch
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, rather than the wall around it. Scottish weather finds any gap, and in a town like Kirkintilloch, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
- Check the sealant is paintable before painting near it
- Make sure movement joints are not pointed over
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Common questions in Kirkintilloch
Is external mastic in Kirkintilloch guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Kirkintilloch in your area for external mastic?
Yes, Kirkintilloch is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How much does external mastic cost in Kirkintilloch?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.

Walls and rooflines in Kirkintilloch
Kirkintilloch 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. 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.
Schools such as Kirkintilloch High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Kirkintilloch include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Lenzie station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
