What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work usually takes a few hours to a few days, depending on the length of joint and the access. For a job in Bearsden, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

About our external mastic in Bearsden
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. We work on render & cladding joints, concrete & block and brickwork movement joints, and common reasons people get in touch are leaking joints around cladding and façade panels and joints where the bead has come unstuck.
Scottish towns like Bearsden mix older stone buildings with newer estates of brick, render and uPVC trims. Older buildings tend to leak at gutter joints, newer ones at dried-out movement joints.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

External mastic in Bearsden: local notes
With historic houses such as Tenement House (about 4.4 miles south-east) nearby, there’s older building stock in the area around Bearsden as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Historic houses such as Tenement House, about 4.4 miles south-east, show how far back building around Bearsden goes, and older homes nearby need a sealant that suits their walls.

How to look after the new joints
After the cure time, these simple habits help:
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Do you need external mastic in Bearsden?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
These are the problems we are asked about most:
- Damp patches traced to an open external joint
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Panel joints letting water in
For site and facilities teams at buildings such as Bearsden Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- What happens if they find a problem under the old sealant
- How long to leave it before use
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In flats with a shared stair in Bearsden, a leak from a failed seal can affect the flat below too, and that is much harder to put right.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
