Questions from Fallin
Does the coastal weather in Fallin affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Fallin?
Yes, Fallin is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, large or small.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
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 and we will confirm how they can be reached safely.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
External mastic in Fallin
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have damp patches traced to an open external joint and movement joints with cracked, split or missing sealant, we can help, whatever the surface.
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.
You get a one-year guarantee, the same in Fallin as everywhere else we work.

Why it’s worth doing now in Fallin
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a place like Fallin, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, 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.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Walk round the building once a year and look at the joints
- Clear growth from the base of walls and joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. For a place like Fallin, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

When to call us in Fallin
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Common reasons people contact us include:
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
Around Fallin, as everywhere, external mastic is only as good as the preparation behind it.

Outside joints around Fallin
Fallin is within about 2 miles of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Stirling station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What we cannot put right
A few problems are outside what sealant work can do:
- Movement that’s more than a sealant joint can take

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
