About our external mastic in Creetown
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. We work on joints between brick and frames, brickwork movement joints and copings & trims, and common reasons people get in touch are gaps where render, brick and frames meet and rain getting behind render or cladding at a joint.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Big or small, it’s backed by our 12-month guarantee.

How the visit works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Outdoor work around Creetown depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

Signs you need external mastic in Creetown
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Joints with sealant missing in places
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
Around Creetown, as everywhere, external mastic is only as good as the preparation behind it.

Creetown: your questions answered
Will you come out to Creetown?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Creetown affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What external mastic looks like in Creetown
Creetown is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Whether the job is in Creetown itself or nearby, the right material for each joint matters as much as a neat finish.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
What else we do in Creetown
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

- Whether there’s mould to deal with

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Leave the joints unpainted unless we’ve said otherwise
- Avoid pressure-washing directly into sealant joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
