External Mastic in Gourdon
We cover Gourdon for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
Surface by surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
External mastic for homes and businesses in Gourdon
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on joints between brick and frames, copings & trims and render & cladding joints, and the jobs we see most are brick movement joints where the sealant has split and panel joints letting water in.
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.
All our work comes with our one-year guarantee.

Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a place like Gourdon, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

FAQs for Gourdon
Do you cover smaller places like Gourdon?
Yes, Gourdon is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do external mastic in Gourdon?
Yes, Gourdon is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we’ve said otherwise
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
How we quote for external mastic
Your quote is based on your job. We look at:
- Whether the work is at height
- Mould in or behind the old joints
- The type of sealant required
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
- If someone has resealed it before
- Any access issues, like height or stairs
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, send an email to info@mrmastic.co.uk.
External mastic in Gourdon: local notes
Gourdon is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Gourdon, as everywhere, external mastic is only as good as the preparation behind it. In the older streets around Old Parish Church And Churchyard, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Gourdon is about 10 miles north-east of Montrose, in Aberdeenshire.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. For a place like Gourdon, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We look at every joint and agree a colour to suit the wall.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
