Errol External Mastic
Problem with your movement joints in Errol? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Damp patches traced to an open external joint
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
When to call us in Errol
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.
Common reasons people contact us include:
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
In and around Errol, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

About our external mastic in Errol
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you are dealing with weeds or debris growing in open joints and brick movement joints where the sealant has split, we can put it right.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Whatever the size of the job, you get the same one-year guarantee in Errol and across Perth and Kinross.

Why it’s worth doing now in Errol
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In an older home around Errol, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Loose or hollow render, which needs re-rendering
- Damp that isn’t coming from the joint
- Cracking across the wall rather than at a joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Keep water from gutters off the wall
- Wash walls gently around the sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere like Errol may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs 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.
How to prepare
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Advice
Common questions in Errol
Does living near the coast affect external mastic in Errol?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Errol?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
External mastic in Errol: local notes
Errol is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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.
Homes close to Errol Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
