External mastic in Pabail Uarach
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. Common call-outs are for sealant pulling away from one side of the joint and joints with sealant missing in places, on copings & trims, brickwork movement joints and render & cladding joints.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
Big or small, you get the same 12-month guarantee.

Why act early in Pabail Uarach
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. Around Pabail Uarach, water from a failed joint in an older stone home can soak into timber and plaster.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Walls and rooflines in Pabail Uarach
Pabail Uarach is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Homes close to Parish Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Around Pabail Uarach, as everywhere, external mastic is only as good as the preparation behind it.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
- Do not let climbing plants root in the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
FAQs for Pabail Uarach
Do you cover Pabail Uarach for external mastic?
Yes, Pabail Uarach is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Is external mastic in a coastal place like Pabail Uarach any different?
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 a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start, matched as closely as the range allows.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Outside jobs in Pabail Uarach need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

Advice
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
