Little Brechin External Mastic
We cover Little Brechin for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
External mastic for homes and businesses in Little Brechin
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We’re often asked to deal with panel joints letting water in and plants rooting in failed movement joints, across façade panels, brickwork movement joints and render & cladding joints.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Surface by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Outside joints around Little Brechin
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Around Little Brechin, as everywhere, external mastic is only as good as the preparation behind it. Managing a site like Brechin High School? Then larger buildings have long runs of movement joint that eventually need resealing.
Little Brechin is about 9 miles west of Montrose, in Angus. From the centre of Little Brechin to the outskirts, external mastic is available for homes and businesses alike. Little Brechin is one of 40 towns and villages in Angus we cover. Our Dundee page covers work nearby.

Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a place like Little Brechin, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Somewhere like Little Brechin may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Related advice
Your questions about external mastic in Little Brechin
Is Little Brechin within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Little Brechin in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Little Brechin is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
What is a movement joint?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
What affects the cost of external mastic
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- How easy the joints are to reach
- The type of sealant required
- Whether old sealant or filler has to be cut out
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- If someone has resealed it before
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and send you a clear quote.
Aftercare tips
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Point out the joints to other trades
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
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.
When something else is needed
It helps to know what we can’t do too:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
