What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on

External mastic in Kirkton of Auchterhouse
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. If you are dealing with water getting into walls through failed joints and joints with sealant missing in places, we can put it right, on render & cladding joints, façade panels and concrete & block alike.
Outside joints can only be sealed when they’re dry, so work in Kirkton of Auchterhouse depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Kirkton of Auchterhouse: your questions answered

Can you do external mastic in Kirkton of Auchterhouse?
Yes. We work across all of Scotland, and Kirkton of Auchterhouse is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How do you reach high-level joints?
Each building is different. Send us pictures and a rough idea of the height.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What do you need from me for a quote?
Tell us what needs doing and where. If we need more, we will ask.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What the job involves on each surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Why act early in Kirkton of Auchterhouse
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Kirkton of Auchterhouse, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
