Cramond External Mastic
Professional external mastic in and around Cramond, with every bit of old sealant taken out first and a 12-month guarantee.
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

External mastic in Cramond
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. If you’re dealing with water getting into walls through failed joints and failed sealant between panels on a façade, we can help.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Looking after it afterwards
So the new joints stay in good condition:
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
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.
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Let us know about earlier repairs to the joints

FAQs for Cramond
I let a flat near Edinburgh Gateway station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Does the coastal weather in Cramond affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where do you work from?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
How we quote for external mastic
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- The old material and how stubborn it is
- How easy the joints are to reach
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
When you call or email, these details help:
- The type of property
- Where the property is
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
We quote each job on its own, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details.

For anyone letting property in or around Cramond, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
What we seal
- Façade panels
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints

What we are called out for in Cramond
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
The most common problems we see are:
- Failed seals between different materials
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
Caroline Park, about 2.6 miles north-east, is one of the historic houses in the wider area around Cramond, and older homes nearby need a sealant that suits their walls.

Cramond buildings and the weather
Cramond is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Edinburgh Gateway station? Then split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Craigmount High School, larger buildings have long runs of movement joint that eventually need resealing.
