Your questions about external mastic in Toogs
Do you cover Toogs for external mastic?
Yes. Our work covers the whole of Scotland, and Toogs is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Does the coastal weather in Toogs affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height and we will confirm how they can be reached safely.
Do you use backing rod?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
External mastic for homes and businesses in Toogs
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Common call-outs are for moss and dirt in joints with no sealant left and rigid filler in a joint that should flex, across joints between brick and frames, copings & trims and render & cladding joints.
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.
Big or small, you get the same 12-month guarantee.

What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. In an older home around Toogs, damp from a failed joint can get into timber and plaster.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
What you get with us
- ARBOMaster approved applicator
- A choice of colours where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- Old sealant always removed completely

What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Toogs need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Do you need external mastic in Toogs?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Keep an eye out for any of the following:
- Weeds or debris growing in open joints
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
For an older house near a landmark such as Burra Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

- When the joint can take water or movement
- Are they insured?

What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
- Render that is blown, hollow or coming away
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Outside joints around Toogs
Toogs 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Around Toogs, as everywhere, external mastic is only as good as the preparation behind it.
