What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. For a place like Inverinate, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Clear the area around the work
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Related advice
External mastic in Inverinate, done properly
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on brickwork movement joints, concrete & block and joints between brick and frames, and people most often call us about moss and dirt in joints with no sealant left and failed sealant between panels on a façade.
In and around a place like Inverinate, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
A one-year guarantee comes as standard.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Common questions in Inverinate
Is external mastic in a coastal place like Inverinate any different?
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 Inverinate for external mastic?
Yes, Inverinate is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.

What external mastic looks like in Inverinate
Inverinate 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Kintail Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we quote for external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The old material and how stubborn it is
- Working hours on commercial sites
- How easy the joints are to reach
- Any mould that needs treating
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The type of property
- Roughly how big the job is
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that is blown, hollow or coming away
- Adding movement joints to masonry that has none
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
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.
Common problems we fix in Inverinate
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Look out for these signs:
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
Around Inverinate, as everywhere, external mastic is only as good as the preparation behind it.
