Questions from Glithno
Is external mastic in a coastal place like Glithno any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Glithno within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
External mastic for homes and businesses in Glithno
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We’re often asked to deal with movement joints with cracked, split or missing sealant and gaps where render, brick and frames meet, on joints between brick and frames, concrete & block and brickwork movement 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.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we’re called out for in Glithno
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
If you let a flat or house near Stonehaven station, split movement joints are easy to miss on a rental until damp shows inside.

What we do, step by step

Mention tracks, gates, ferries or anything else about the route.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.

Work for landlords, hotels and businesses
If you manage several properties in or around Glithno, several properties can go on one quote. Just tell us the addresses and what each one needs.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Why it’s worth doing now in Glithno
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why book with us
- Tidy, careful work
- A sealant colour to suit the surroundings
- 12-month guarantee on every job
- We’re fully insured

Glithno buildings and the weather
Glithno is within about 2 miles 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 sound outside sealant is part of that.
For site and facilities teams at buildings such as Mackie Academy, its movement joints, gutters and trims need looking after like any other building’s.
