External mastic for homes and businesses in Port na Craig
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. Common call-outs are for sealant that has lost its bond to the brick or render and old sealant gone brittle and cracked, across render & cladding joints, brickwork movement joints and façade panels.
In and around a place like Port na Craig, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
Your job is guaranteed for a year, as with all our work.

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Port na Craig, 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Walls and rooflines in Port na Craig
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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Pitlochry station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Baptist Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Croftinloan School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Port na Craig: your questions answered
Do you cover smaller places like Port na Craig?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Pitlochry station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When something else is needed
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Movement that’s more than a sealant joint can take
- 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’ll say what we think.

- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.

Looking after it afterwards
So the new joints stay in good condition:
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
