I let a flat near Perth station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.

Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
About our external mastic in Scoonieburn
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. If you have old sealant gone brittle and cracked and movement joints filled with mortar instead of sealant, we can put it right, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Whatever the size of the job, you get the same one-year guarantee in Scoonieburn and across Perth and Kinross.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Subsidence or other structural problems
- Damp that is not coming from the joint
- Failed render or damaged cladding panels
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Façade panels
- Copings & trims
- Render & cladding joints
Common problems we fix in Scoonieburn
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
People normally contact us when they notice one of these:
- Gaps where render, brick and frames meet
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
Rented homes near Perth station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- How hidden problems are handled
- When the joint can take water or movement
- The length of the guarantee
- Whether all the old sealant comes out first
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How to look after the new joints
Aftercare is simple:
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Ask before painting over external sealant
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Around Scoonieburn, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Keep children and pets away from the work area

Outside joints around Scoonieburn
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Managing a site like Perth High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
