Questions from Scatsta
Do you cover smaller places like Scatsta?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in a coastal place like Scatsta any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Are you fully insured?
Yes. We are fully insured for every job we do.
How do you reach high-level joints?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
External mastic in Scatsta
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on brickwork movement joints, façade panels and render & cladding joints, and the jobs we see most are movement joints filled with mortar instead of sealant and failed sealant between panels on a façade.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Signs you need external mastic in Scatsta
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
These are the problems we’re asked about most:
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
In and around Scatsta, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Honest limits
We won’t take on work that won’t last, so these are the limits:
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.

Landlords, agents and businesses in Scatsta
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
If you manage several properties in or around Scatsta, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. 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.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Walls and rooflines in Scatsta
Scatsta is close to 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.
Whether the job is in Scatsta itself or nearby, the right material for each joint matters as much as a neat finish.

How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
