About our external mastic in Monikie
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. If you are dealing with old sealant gone brittle and cracked and cracked joints where brick meets render or frames, we can put it right, on joints between brick and frames, brickwork movement joints and concrete & block alike.
In and around a place like Monikie, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

The process
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Somewhere like Monikie 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 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.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In a place like Monikie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
Why us?
- A sealant colour to suit the surroundings
- Old sealant always removed completely
- Full insurance on every job
- White, clear, grey or coloured to suit, where the product allows

Outside joints around Monikie
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of 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.
If you live in an older home near Parish Church And Burial-Ground, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Your questions about external mastic in Monikie
Is Monikie within the area you cover?
Yes. Monikie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Monikie in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Monikie is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building. Your quote will say how long we expect yours to take.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
When it isn’t the sealant
It helps to know what we cannot do:
- Render that is blown, hollow or coming away
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Where we work in Monikie
- Façade panels
- Copings & trims
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
When to call us in Monikie
Every building moves. 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.
The problems people usually mention when they call include:
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
If you let a flat or house near Monifieth station, split movement joints are easy to miss on a rental until damp shows inside.
