External mastic for homes and businesses in Cammachmore
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on concrete & block, façade panels and copings & trims, and the jobs we see most are damp patches traced to an open external joint and weathered mastic that no longer stretches.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much there is to do
- Any mould that needs treating
- Whether the work is at height
- The type of sealant required
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Helping us quote
What to tell us when you ask for a quote:
- Roughly how big the job is
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Leave it or put it right?
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 Cammachmore, damp from a failed joint can get into timber and plaster.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
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.
When something else is needed
It helps to know what we cannot do:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
- Façade panels
- Joints between brick and frames
When to call us in Cammachmore
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
The problems people usually mention when they call are:
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
For site and facilities teams at buildings such as Portlethen Academy, larger buildings have long runs of movement joint that eventually need resealing.

Walls and rooflines in Cammachmore
Cammachmore is within about 1 mile 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Portlethen station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Questions from Cammachmore
Is Cammachmore within the area you cover?
Yes. Cammachmore 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.
Is external mastic in a coastal place like Cammachmore any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Around Cammachmore, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Mention any tricky access
