External mastic in Blairgowrie and Rattray, done properly
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Typical jobs include water getting into walls through failed joints and movement joints filled with mortar instead of sealant, across brickwork movement joints, joints between brick and frames and façade panels.
Harled walls are common in Scottish towns like Blairgowrie and Rattray, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Rooflines take their share of the weather as well.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from Blairgowrie and Rattray
Is Blairgowrie and Rattray in your area for external mastic?
Yes. We work across all of Scotland, and Blairgowrie and Rattray is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
How do I get a quote for external mastic in Blairgowrie and Rattray?
The easiest way is to send an email to info@mrmastic.co.uk with a few details of the job. You will get a clear, fixed price before any work starts.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. We’ll confirm how long when we quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Common problems we fix in Blairgowrie and Rattray
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
If you look after a building such as Blairgowrie High School, larger buildings have long runs of movement joint that eventually need resealing.
Before you book anyone

Keeping the joints in good condition
After the cure time, these simple habits help:
- Make sure movement joints are not pointed over
- Keep water from gutters off the wall
- Wash walls gently around the sealant
- Have failed joints looked at early
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Blairgowrie and Rattray buildings and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In Blairgowrie and Rattray, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
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. You will have a clear quote before any work starts, so you know where you stand.

What we cannot put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damp that isn’t coming from the joint
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
What we seal
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
- Concrete & block
Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
