External & façade joints in Sprouston, Scottish Borders
Sealing brickwork movement joints, render, cladding and façade joints for Sprouston, backed by a one-year guarantee. Call for a quick quote.
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
Looking after it afterwards
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
External mastic in Sprouston, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We’re often asked to deal with failed seals between different materials and movement joints with cracked, split or missing sealant, across copings & trims, concrete & block and render & cladding joints.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, in Sprouston and everywhere else we cover.

Sprouston: your questions answered
Do you cover Sprouston for external mastic?
Yes. Our work covers the whole of Scotland, and Sprouston is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is there a guarantee on external mastic in Sprouston?
All our work, in Sprouston and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

Landlords, agents and businesses in Sprouston
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Outdoor work around Sprouston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Clear the area around the work

Sprouston buildings and the weather
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Sprouston Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Kelso High School? Then larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Sprouston
Sealing over the top of old mastic does not hold for long. The new layer can’t 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 once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
