What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Outside jobs in Cumbernauld Village need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Advice
External mastic for homes and businesses in Cumbernauld Village
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. Typical jobs include moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, across brickwork movement joints, concrete & block and joints between brick and frames.
External sealant needs dry surfaces, so outdoor work around Cumbernauld Village is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Whatever the size of the job, you get the same one-year guarantee.

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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 fails, we can still redo it.
Cumbernauld Village questions
Do you cover smaller places like Cumbernauld Village?
Yes. Cumbernauld Village is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Cumbernauld station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Where do you work from?
We work from Crawley. We cover Cumbernauld Village and the rest of North Lanarkshire.
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 so the bead can stretch.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
When to call us in Cumbernauld Village
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
The most common problems we see are:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
Rented homes near Cumbernauld station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- Who does the work, and how experienced they are
- Whether VAT is included
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid pressure-washing directly into sealant joints
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
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. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged 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.
