External mastic for homes and businesses in An Druim Beag
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for damp patches traced to an open external joint and hard, crazed mastic that has stopped moving, across façade panels, joints between brick and frames and brickwork movement joints.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

FAQs for An Druim Beag
Do you cover An Druim Beag for external mastic?
Yes. Our work covers the whole of Scotland, and An Druim Beag is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is An Druim Beag within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Get split or bare joints resealed while the damage is small
- Never let anyone fill a movement joint with mortar
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Walls and rooflines in An Druim Beag
An Druim Beag is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. An Druim Beag 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.
In and around An Druim Beag, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How it works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Related advice
Surface by 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.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Do you need external mastic in An Druim Beag?
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
These are the problems we’re asked about most:
- Panel joints letting water in
- Joints pointed up with cement by mistake
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
Whether the job is in An Druim Beag itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- What product goes in the joint
- When the joint can take water or movement
- Whether you can choose the colour
- What the quote includes, VAT included or not
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal

DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
