- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none

External mastic for homes and businesses in Aird
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. Typical jobs include leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving, across joints between brick and frames, brickwork movement joints and concrete & block.
External sealant needs dry surfaces, so outdoor work around Aird is planned around the weather. Let us know about access to every wall and roofline.
A one-year guarantee comes as standard.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Wash walls gently around 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.
What affects the cost of external mastic
Your quote is based on your job. We look at:
- The number of rooms or windows
- The old material and how stubborn it is
- Access and height
- Any mould that needs treating
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What to tell us for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- Roughly how big the job is
- Whether it has been sealed before
- Where the property is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Common problems we fix in Aird
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
The problems people usually mention when they call include:
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
- Joints with sealant missing in places
In and around Aird, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. 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.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs 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
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

What external mastic looks like in Aird
Aird is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
If you look after a building such as Aird Primary School, larger buildings have long runs of movement joint that eventually need resealing.

FAQs for Aird
Do you cover smaller places like Aird?
Yes, Aird is covered. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect external mastic in Aird?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
How do I get a quote for external mastic in Aird?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
