External mastic in Old Deer, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you’re dealing with joints with sealant missing in places and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Old Deer depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
A 12-month guarantee comes as standard.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Around Old Deer, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why us?
- Every job guaranteed for a year
- Tidy, careful work
- Sanitary silicone with an anti-fungal additive in wet areas
- You choose the colour before work begins

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Related advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Old Deer: your questions answered
Will you come out to Old Deer?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is external mastic in Old Deer guaranteed?
All our work, in Old Deer and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
What do you need from me for a quote?

Common problems we fix in Old Deer
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
It’s worth asking for a quote if you see:
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
In the older streets around St Drostan's Episcopal Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Before booking anyone

Walls and rooflines in Old Deer
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 joints where harling meets other materials need a sealant that can grip and flex.
If you look after a building such as Mintlaw Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check external joints each spring
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we’ve said otherwise
- Avoid pressure-washing directly into sealant joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
What affects the cost of external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- When we can work, for business premises
- How easy the joints are to reach
- Whether there’s mould to deal with
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
