Juniper Green: your questions answered
Is Juniper Green within the area you cover?
Yes, Juniper Green is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Wester Hailes station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How much does external mastic cost in Juniper Green?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
External mastic in Juniper Green
On houses, flats and commercial buildings across Juniper Green, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you’re dealing with weeds or debris growing in open joints and damp patches traced to an open external joint, we can help, whatever the surface.
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.
All our work comes with a 12-month guarantee.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What affects the quote in Juniper Green
Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The size of the job
- The type of sealant required
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
To make quoting easier, let us know:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- If someone has resealed it before
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.
Outside joints around Juniper Green
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
In and around Juniper Green, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

If you manage several properties in or around Juniper Green, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

What we’re called out for in Juniper Green
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Plants rooting in failed movement joints
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
If you let a flat or house near Wester Hailes station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Keeping the joints in good condition
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
- Avoid pressure-washing directly into sealant joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
