Wilkieston buildings and the weather
Historic houses like Howden House (about 4.2 miles west) are a reminder that the area around Wilkieston has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Howden House, about 4.2 miles west, is one of the historic houses in the wider area around Wilkieston.

External mastic in Wilkieston, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. If you have rigid filler in a joint that should flex and panel joints letting water in, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix
We will always be straight with you, so here’s what sealant cannot fix:
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Façade panels
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outdoor work around Wilkieston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Related advice
Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Your questions about external mastic in Wilkieston
Is Wilkieston in your area for external mastic?
Yes, Wilkieston is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Wilkieston?
Yes, Wilkieston is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Wilkieston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Common problems we fix in Wilkieston
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
If you let a flat or house near Kirknewton station, outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- How much experience the applicator has
- Whether the sealant suits the joint
- What preparation is included
- How long to leave it before use
How to look after the new joints
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
