External Mastic in Hallowood
Professional external mastic in and around Hallowood, with old sealant always removed completely and a 12-month guarantee.
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
Should I try it myself first?
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, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How we handle external mastic in Hallowood
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you’re dealing with damp patches traced to an open external joint and hard, crazed mastic that has stopped moving, we can help, whatever the surface.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Your job is guaranteed for a year, as with all our work.

When to call us in Hallowood
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
If you live in an older home near St Andrews-Lhanbryd Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Whether the sealant suits the joint
- Whether you can choose the colour
- Who does the work, and how experienced they are

FAQs for Hallowood
Do you cover smaller places like Hallowood?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Elgin station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
How do I get a quote for external mastic in Hallowood?

Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.

Walls and rooflines in Hallowood
Harled (roughcast) walls are common in Scotland, 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 failed outside joints work against that.
Managing a site like Elgin High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Elgin station, split movement joints are easy to miss on a rental until damp shows inside.

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.
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.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Render that’s blown, hollow or coming away
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
