What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere like Voe may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

External mastic in Voe
On houses, flats and commercial buildings across Voe, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on concrete & block, façade panels and joints between brick and frames, and people most often call us about joints where the bead has come unstuck and damp patches traced to an open external joint.
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, so they need a sealant that moves with the building.
All our work is covered by our 12-month guarantee.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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 doesn’t work out, we can still put it right.
Landlord and commercial work in Voe
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Common problems we fix in Voe
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
The problems people usually mention when they call include:
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
- Failed seals between different materials
- Sealant pulling away from one side of the joint
In the older streets around Voe Kirk, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Voe questions
Is Voe in your area for external mastic?
Yes. We work across all of Scotland, and Voe is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is external mastic in a coastal place like Voe any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we will say how long yours will take.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall. If it has already been filled, we can normally cut it out and reseal it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.

Voe buildings and the weather
Voe 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. On the islands, wind and salt spray are hard on outside sealant.
In and around Voe, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Voe is in the Shetland Islands. From the centre of Voe to the outskirts, we cover external mastic for every kind of property, from flats and houses to offices and hotels. Across the Shetland Islands, we cover 63 places, and Voe is one of them.
Work in ZE2 works the same way as everywhere else we cover. You’ll find streets such as Norderhoull, Isles Road and Mulla. Neighbouring places we cover for external mastic include Brae (4 miles north-west), Dury (4 miles south-east), Vidlin (4 miles east), Scatsta (5 miles north) and Sullom (6 miles north-west). Larger places within reach include Lerwick (15 miles south), Sound (15 miles south) and Scalloway (15 miles south). For island and remote addresses, the job takes a little more planning, so mention it when you ask for a quote.
