About our external mastic in Levenwick
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. Typical jobs include leaking joints around cladding and façade panels and sealant pulling away from one side of the joint, on joints between brick and frames, copings & trims and façade panels.
External sealant needs dry surfaces, so outdoor work around Levenwick is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. Around Levenwick, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Advice
Common problems we fix in Levenwick
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
The problems people normally mention when they call are:
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Failed seals between different materials
For jobs in and around Levenwick, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
If you are set on DIY, put the effort into 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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Why it’s worth doing now in Levenwick
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Other services in Levenwick
Levenwick buildings and the weather
Levenwick is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.
In and around Levenwick, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
Joints and surfaces we work on
- Brickwork movement joints
- Concrete & block
- Façade panels
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
