External mastic in Kirkpatrick-Fleming, done properly
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have damp patches traced to an open external joint and plants rooting in failed movement joints, we can put it right, on render & cladding joints, façade panels and copings & trims alike.
External sealant needs dry surfaces, so outdoor work around Kirkpatrick-Fleming is planned around the weather. Let us know about access to every wall and roofline.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

When to call us in Kirkpatrick-Fleming
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
If you let a flat or house near Gretna Green station, outside joints that have cracked can let damp into a rental, so check them between lets.

Kirkpatrick-Fleming buildings and the weather
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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For an older house near a landmark such as Kirkpatrick Fleming Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why it’s worth doing now in Kirkpatrick-Fleming
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a place like Kirkpatrick-Fleming, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Kirkpatrick-Fleming: your questions answered
Is Kirkpatrick-Fleming within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Gretna Green station?
Yes. We work for letting agents and landlords as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. If it has already been filled, we can normally cut it out and reseal it.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We’ll confirm how long when we quote.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Aftercare tips
A little care helps the new joints last. We recommend:
- Don’t let climbing plants root in the sealant
- Act on the first splits you see
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Any mould that needs treating
- The type of sealant required
- Any working-time requirements on site
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Any previous sealing or DIY work
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
