How we handle external mastic in Gauldry
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We work on brickwork movement joints, façade panels and copings & trims, and people most often call us about rigid filler in a joint that should flex and weathered mastic that no longer stretches.
External sealant needs dry surfaces, so outdoor work around Gauldry is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Whatever the size of the job, it’s backed by our 12-month guarantee in Gauldry and across Fife.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Check external joints each spring
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
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. Your quote takes all of that into account.
Why choose Mr Mastic in Gauldry
- A choice of colours where the product allows
- Experience in homes, commercial sites and hotels
- You choose the colour before work begins
- Neat joints and a tidy finish
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How the job changes by surface
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 before sealing.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- The number and length of the joints
- The old material and how stubborn it is
- When we can work, for business premises
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
Before you ask for a quote, have a think about:
- The address or postcode of the job
- A few pictures by email, if you can
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
Walls and rooflines in Gauldry
Gauldry is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Dundee station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Homes close to Gauldry Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
