External & façade joints in Ardbrecknish, Argyll and Bute
We cover Ardbrecknish for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
About our external mastic in Ardbrecknish
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 joint doesn’t stand out. We work on façade panels, concrete & block and joints between brick and frames, and common reasons people get in touch are failed sealant between panels on a façade and rigid filler in a joint that should flex.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Common problems we fix in Ardbrecknish
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Panel joints letting water in

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
- Render that is blown, hollow or coming away
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
