External mastic in Glen Moriston, done properly
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 will confirm what access is needed. We work on façade panels, joints between brick and frames and render & cladding joints, and the jobs we see most are leaking joints around cladding and façade panels and weathered mastic that no longer stretches.
External sealant needs dry surfaces, so outdoor work around Glen Moriston is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Movement that’s more than a sealant joint can take
- Render that is blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

Your questions about external mastic in Glen Moriston
Will you come out to Glen Moriston?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do external mastic in Glen Moriston?
Yes, Glen Moriston 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, and we’ll give you a clear price.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What external mastic looks like in Glen Moriston
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For jobs in and around Glen Moriston, choosing the right material for each joint is as important as a tidy finish. In and around Glen Moriston, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Glen Moriston is about 30 miles south-west of Inverness, in Highland. Jobs in Glen Moriston get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Glen Moriston is one of 253 places in Highland we cover for external mastic.

What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
How we quote for external mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Which sealant suits the joint
- Mould in or behind the old joints
- The number and length of the joints
- Access and height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- Pictures of the joints, sent by email
- The address or postcode of the job
- Any previous sealing or DIY work
There’s no standard price list. Instead, we give you a clear quote for your job. To get started, drop us a line at info@mrmastic.co.uk.
Why it’s worth doing now in Glen Moriston
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. In an older home around Glen Moriston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
- Keep soil, plants and ivy away from the joints
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.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
If you manage several properties in or around Glen Moriston, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
How it works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. For a place like Glen Moriston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
