External Mastic in Baile Ailein
Movement joints in Baile Ailein need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.

How we handle external mastic in Baile Ailein
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. If you have panel joints letting water in and water getting into walls through failed joints, we can put it right.
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 something is not right with it in that time, tell us and we will put it right.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In an older home around Baile Ailein, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- 12-month guarantee on every job
- Quality sealants from Arbo and Everbuild
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet

What external mastic looks like in Baile Ailein
Baile Ailein is within about 1 mile of 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Baile Ailein, as everywhere, external mastic is only as good as the preparation behind it. For jobs in and around Baile Ailein, choosing the right material for each joint is as important as a tidy finish.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Questions from Baile Ailein
Is Baile Ailein within the area you cover?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Baile Ailein any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. Around Baile Ailein, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit

Advice
Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Landlords, agents and businesses in Baile Ailein
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Ask before painting over external sealant
- Keep water from gutters off the wall
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.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
