What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Outdoor work around Glencarse 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 start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- 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
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

External mastic for homes and businesses in Glencarse
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have movement joints filled with mortar instead of sealant and leaking joints around cladding and façade panels, we can help, on joints between brick and frames, façade panels and copings & trims alike.
External sealant needs dry surfaces, so outdoor work around Glencarse is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job.

Why it’s worth doing now in Glencarse
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will tell you how long to expect.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Are you fully insured?
Yes. We’re fully insured.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

What external mastic looks like in Glencarse
Glencarse 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Glencarse, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

When to call us in Glencarse
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
These are the problems we’re asked about most:
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
In the older streets around All Saints Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

- The length of the guarantee
What sealant work cannot fix
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Façade panels
Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
