External mastic in Crail
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on concrete & block, joints between brick and frames and brickwork movement joints, and the jobs we see most are sealant that has lost its bond to the brick or render and water getting into walls through failed joints.
In and around a place like Crail, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
Every job comes with our 12-month guarantee.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Outside jobs in Crail need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- Tell us about any water getting in

Advice
Common problems we fix in Crail
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Most people get in touch after spotting something like this:
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
If you live in an older home near Parish Church Hall, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Questions from Crail
Does the coastal weather in Crail affect outside sealant?
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 cover smaller places like Crail?
Yes. Crail is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
How do I get a quote for external mastic in Crail?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will say how long yours will take.
What external mastic looks like in Crail
Crail 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Crail, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
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.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
