How we handle external mastic in Ravenswood
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. If you’re dealing with moss and dirt in joints with no sealant left and hard, crazed mastic that has stopped moving, we can help.
Outside joints can only be sealed when they’re dry, so work in Ravenswood depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Each job carries a 12-month guarantee, large or small.

What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
- Concrete & block
When to call us in Ravenswood
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
The problems people normally mention when they call include:
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
- Panel joints letting water in
- Damp patches traced to an open external joint
If you look after a building such as Our Lady's High, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether the sealant suits the joint
- Whether they’re fully insured
- Is the old sealant removed completely?
- What preparation is included
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Show decorators and builders where the movement joints are
- Do not let climbing plants root in the sealant
- Check external joints each spring
- Wash walls gently around the sealant
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
Outside joints around Ravenswood
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to St Mungo's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Greenfaulds station? Then split movement joints are easy to miss on a rental until damp shows inside.

What happens if it’s left?

FAQs for Ravenswood
Do you cover Ravenswood for external mastic?
Yes. Our work covers the whole of Scotland, and Ravenswood is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Ravenswood?
Yes, Ravenswood is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- Working hours on commercial sites
- Mould in or behind the old joints
- How much there is to do
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Whether it has been sealed before
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details and send photos if you have them.
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Outdoor work around Ravenswood depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
