External Mastic in Wester Broom

External mastic for homes and businesses in Wester Broom
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you have old sealant gone brittle and cracked and panel joints letting water in, we can help, whatever the surface.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Wester Broom, repairs to shared parts are generally agreed between the owners, often through a property factor.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Your questions about external mastic in Wester Broom
I let a flat near South Gyle station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do repairs to the shared parts of a tenement in Wester Broom get organised?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
What is backing rod for?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Quotes for external mastic in Wester Broom
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The type of sealant required
- Whether the work is at height
- How much there is to do
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- The rough size of the job
- The type of property
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Inside a flat in Wester Broom, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Advice
How to look after the new joints
After the cure time, these simple habits help:
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Have failed joints looked at early
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.

Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a tenement flat in Wester Broom, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- We never seal over old sealant
- A 12-month guarantee on all work

Should I try it myself first?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
