How we handle external mastic in Whitecross
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are movement joints filled with mortar instead of sealant and old sealant gone brittle and cracked.
External sealant needs dry surfaces, so outdoor work around Whitecross is planned around the weather. Let us know about access to every wall and roofline.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Signs you need external mastic in Whitecross
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Plants rooting in failed movement joints
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake

Outside joints around Whitecross
Whitecross 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.
For an older house near a landmark such as Muiravonside Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Linlithgow Academy, its movement joints, gutters and trims need looking after like any other building’s.

How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Letting agents and landlords in Whitecross can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
How we quote for external mastic
We quote each job individually. These are the things that affect it:
- The size of the job
- When we can work, for business premises
- The product the joint needs
- How many rooms, windows or areas are involved
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- Roughly how big the job is

- Pictures of the joints, sent by email

What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we’ve said otherwise
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Around Whitecross, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we’ll 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.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention if the joints have been sealed before

Advice
FAQs for Whitecross
Do you work for landlords with property near Linlithgow station?
Yes. We work for landlords and letting agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Whitecross?
Yes, Whitecross is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Which products do you use?
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.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
