External & façade joints in Bourtreehill, North Ayrshire
We cover Bourtreehill for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Failed seals between different materials
Why act early in Bourtreehill
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In an older home around Bourtreehill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why us?
- Approved under the ARBOMaster scheme
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
- We agree the colour with you first

External mastic for homes and businesses in Bourtreehill
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you are dealing with rigid filler in a joint that should flex and sealant pulling away from one side of the joint, we can put it right.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
You are covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

What else we do in Bourtreehill
Looking after it afterwards
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
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.
When something else is needed
Before booking, it’s worth knowing the limits:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

External mastic in Bourtreehill: local notes
Bourtreehill is within about 3 miles 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. With historic houses such as Girgenti House (about 3.1 miles north) nearby, there’s older building stock in the area around Bourtreehill as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Greenwood Academy, its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Girgenti House, about 3.1 miles north, show how far back building around Bourtreehill goes.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Common problems we fix in Bourtreehill
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Most people get in touch after spotting something like this:
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
For landlords with property near Irvine station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Around Bourtreehill, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- 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.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

What affects the cost of external mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The product the joint needs
- Any working-time requirements on site
- The number and length of the joints
- Any mould that needs treating
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- How we’d reach the joints
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel

Common questions in Bourtreehill
Does living near the coast affect external mastic in Bourtreehill?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Bourtreehill within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
