External mastic in Whiting Bay
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We work on joints between brick and frames, render & cladding joints and copings & trims, and the jobs we see most are cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant.
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, so they need a sealant that moves with the building.
Big or small, you get the same one-year guarantee.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the building. Outside jobs in Whiting Bay need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

External mastic in Whiting Bay: local notes
Whiting Bay is within about 1 mile of 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.

FAQs for Whiting Bay
Is external mastic in a coastal place like Whiting Bay any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Whiting Bay?
Yes. Whiting Bay is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Leave the joints unpainted unless we’ve said otherwise
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
Different surfaces, different methods
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
Signs you need external mastic in Whiting Bay
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
- Panel joints letting water in
For an older house near a landmark such as Former Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- Are they insured?
- Is the old sealant removed completely?
