How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a city area like Priesthill, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, 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.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Damp that isn’t coming from the joint
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
Surfaces we seal

External mastic in Priesthill: local notes
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. With historic houses such as Pollok House (about 1.5 miles north-east) nearby, there’s older building stock in the area around Priesthill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as St. Paul's High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Pollok House, about 1.5 miles north-east, show how far back building around Priesthill goes, and older homes nearby need a sealant that suits their walls.

Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
Priesthill: your questions answered
Is Priesthill in your area for external mastic?
Yes. We work across all of Scotland, and Priesthill is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll send you a clear quote.

What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you fully insured?
Yes. We’re fully insured for every job we do.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Signs you need external mastic in Priesthill
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Common reasons people contact us include:
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Movement joints with cracked, split or missing sealant
For landlords with property near Nitshill station, outside joints that have cracked can let damp into a rental, so check them between lets.
