- Rain getting behind render or cladding at a joint
Signs you need external mastic in Auldcathie
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
Managing a site like Winchburgh Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

How we handle external mastic in Auldcathie
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’ll confirm what access is needed. If you’re dealing with weeds or debris growing in open joints and rain getting behind render or cladding at a joint, we can help, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Auldcathie questions
I let a flat near Uphall station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Auldcathie?
Yes. Auldcathie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
How much does external mastic cost in Auldcathie?
Size, access and the old material all affect the cost. Ask us for a quote.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
What affects the cost of external mastic
Call for a quick quote. The main things that affect it are:
- Access and height
- The type of sealant required
- The number and length of the joints
- Working hours on commercial sites
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
Helping us quote
What to tell us when you ask for a quote:
- Where the property is
- How we’d reach the joints
- Pictures of the joints, sent by email
- The type of property
If you are in Auldcathie and need external mastic, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. 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.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Why us?
- 20+ years of sealant experience
- Fully insured
- Neat joints and a tidy finish
- A 12-month guarantee on all work

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Auldcathie buildings and the weather
Auldcathie is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you let a flat or house near Uphall station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Auldcathie Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How it works
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 the size of the job. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
