Newbattle External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Newbattle and across Midlothian. Fully insured, ARBOMaster approved and guaranteed for a year.
- Hard, crazed mastic that has stopped moving
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
External mastic in Newbattle, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you are dealing with joints with sealant missing in places and sealant pulling away from one side of the joint, we can put it right.
In and around a place like Newbattle, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
You’re covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Newbattle questions
Can you help a landlord with a rental near Eskbank station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is Newbattle in your area for external mastic?
Yes, Newbattle is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How much does external mastic cost in Newbattle?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
When will the joints need doing again?
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.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. For a place like Newbattle, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Related advice
External mastic in Newbattle: local notes
With historic houses such as Melville Castle (about 1.2 miles north-west) nearby, there’s older building stock in the area around Newbattle as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Eskbank station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Newbattle Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common problems we fix in Newbattle
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
It’s worth asking for a quote if you see:
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
- Panel joints letting water in
Managing a site like Dalkeith High School? Then larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
- Whether they’re fully insured
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
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.
