About our external mastic in Stuartfield
On houses, flats and commercial buildings across Stuartfield, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on façade panels, copings & trims and concrete & block, and people most often call us about water getting into walls through failed joints and gaps where render, brick and frames meet.
External sealant needs dry surfaces, so outdoor work around Stuartfield is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What external mastic looks like in Stuartfield
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.
Schools such as Mintlaw Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
- Have failed joints looked at early
- Clear growth from the base of walls and joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Stuartfield need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- 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.
- 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 if parking is tricky
- Clear the area around the work
- Try not to wet indoor joints just before the visit

What affects the quote in Stuartfield
You’ll get a clear quote before any work starts. It takes into account:
- When we can work, for business premises
- The product the joint needs
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- Any previous sealing or DIY work
- Where the property is
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
When to call us in Stuartfield
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
These are the problems we are asked about most:
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
Around Stuartfield, as everywhere, external mastic is only as good as the preparation behind it.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
FAQs for Stuartfield
Is there a guarantee on external mastic in Stuartfield?
All our work, in Stuartfield and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Stuartfield in your area for external mastic?
Yes. We work across all of Scotland, and Stuartfield is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Which products do you use?
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.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
