External mastic for homes and businesses in Inverasdale
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. We are often asked to deal with leaking joints around cladding and façade panels and gaps where render, brick and frames meet, across render & cladding joints, concrete & block and brickwork movement joints.
In and around a place like Inverasdale, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
Big or small, it’s backed by our one-year guarantee in Inverasdale and across Highland.

External mastic in Inverasdale: local notes
Inverasdale 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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Inverasdale is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
For jobs in and around Inverasdale, choosing the right material for each joint is as important as a tidy finish.

Questions from Inverasdale
Can you do external mastic in Inverasdale?
Yes. We work across all of Scotland, and Inverasdale 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 Inverasdale affect outside sealant?
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 work for letting agents?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will tell you when we quote.
How much does external mastic cost in Inverasdale?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts, matched as closely as the range allows.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Brickwork movement joints
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Aftercare tips
A little care helps the new joints last. We recommend:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints aren’t pointed over
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
