Common questions in Garvald
Do you cover Garvald for external mastic?
Yes, Garvald is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Is Garvald within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do I need to be at home?
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.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
External mastic in Garvald, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have joints where the bead has come unstuck and plants rooting in failed movement joints, we can put it right, on façade panels, copings & trims and render & cladding joints alike.
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 covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Check the sealant is paintable before painting near it
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
- Avoid pressure-washing directly into sealant joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
Walls and rooflines in Garvald
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
When to call us in Garvald
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.
The problems people usually mention when they call include:
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Failed seals between different materials
- Old sealant gone brittle and cracked
Rented homes near East Linton station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What else we do in Garvald
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. For a place like Garvald, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Related advice
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. 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.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.
