External & façade joints in Boghead, South Lanarkshire
Problem with your movement joints in Boghead? We remove the old material, prepare the joints and seal them properly.
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
External mastic in Boghead
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Typical jobs include sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant, on concrete & block, joints between brick and frames and façade panels.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the quote in Boghead
We do not publish a price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- The product the joint needs
- Access and height
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
Getting a quote is simple: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
Why act early in Boghead
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Why us?
- Fully insured
- We leave the area clean and tidy
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Boghead 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Around Boghead, as everywhere, external mastic is only as good as the preparation behind it.

Common problems we fix in Boghead
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
Managing a site like Lesmahagow High School? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Which sealant they’ll use, and why

When something else is needed
Before you book, it’s worth knowing the limits too:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
