Can I do it myself?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
About our external mastic in Quothquan
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you’re dealing with panel joints letting water in and joints where the bead has come unstuck, we can put it right.
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.
Our work is backed for twelve months, in Quothquan and everywhere else we cover.

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Why it’s worth doing now in Quothquan
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Quothquan, water from a failed joint in an older stone home can soak into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Walls and rooflines in Quothquan
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. 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.
In the older streets around Quothquan Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we’re called out for in Quothquan
A lot of failed joints come down to preparation: 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.
The problems people generally mention when they call include:
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
For landlords with property near Carstairs station, outside joints that have cracked can let damp into a rental, so check them between lets.

When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course

Questions from Quothquan
Will you come out to Quothquan?
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.
Do you cover Quothquan for external mastic?
Yes. Our work covers the whole of Scotland, and Quothquan is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
When will the joints need doing again?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
