External & façade joints in Kennethmont, Aberdeenshire

- Old sealant gone brittle and cracked
- Failed seals between different materials
- Damp patches traced to an open external joint
Surface by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
How we handle external mastic in Kennethmont
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you are dealing with weeds or debris growing in open joints and sealant that has lost its bond to the brick or render, we can help, 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.
Your job is guaranteed for a year, as with all our work.

Why act early in Kennethmont
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In a place like Kennethmont, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Outside joints around Kennethmont
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. 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.
For an older house near a landmark such as Kennethmont Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Make sure movement joints are not pointed over
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
- Keep high-pressure jets off the joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

Common problems we fix in Kennethmont
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Most people get in touch when they notice one of these:
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
For landlords with property near Insch station, split movement joints are easy to miss on a rental until damp shows inside.
