Strathmartine questions
Can you help a landlord with a rental near Dundee station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Strathmartine?
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.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Do you have insurance?
Yes. We are fully insured for every job we do.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.

What external mastic looks like in Strathmartine
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. With historic houses such as Camperdown House (about 2.1 miles south-west) nearby, there’s older building stock in the area around Strathmartine as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Historic houses such as Camperdown House, about 2.1 miles south-west, show how far back building around Strathmartine goes. Rented homes near Dundee station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Outside jobs in Strathmartine need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

Advice

We won’t take on work that will not last, so here’s what sealant cannot put right:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

When to call us in Strathmartine
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
The problems people usually mention when they call include:
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
Schools such as Baldragon Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Before you book anyone
- How long to leave it before use
- How the surfaces are prepared before sealing
- Whether the sealant suits the joint
- How long the guarantee is
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 the old joint is cut out fully first. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
