External mastic for Strathore and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep movement joints as flexible joints, not mortar
- Keep high-pressure jets off the joints
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
External mastic for homes and businesses in Strathore
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on concrete & block, joints between brick and frames and brickwork movement joints, and the jobs we see most are joints with sealant missing in places and rigid filler in a joint that should flex.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Strathore
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Do you need external mastic in Strathore?
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.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
- Gaps where render, brick and frames meet
Rented homes near Glenrothes with Thornton station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether you can choose the colour
- Which sealant they’ll use, and why
- How hidden problems are handled
- Whether they’re fully insured
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere like Strathore may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Common questions in Strathore
Can you help a landlord with a rental near Glenrothes with Thornton station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Will you come out to Strathore?
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.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. We’ll reseal it with a flexible sealant.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.

External mastic in Strathore: local notes
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Kirkcaldy High School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Old Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
