What external mastic looks like in Guardbridge
Guardbridge 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. 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 Guardbridge, as everywhere, external mastic is only as good as the preparation behind it.

About our external mastic in Guardbridge
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you’re dealing with movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint, we can help, on brickwork movement joints, façade panels and render & cladding joints alike.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
You get a 12-month guarantee, the same in Guardbridge as everywhere else we work.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Outdoor work around Guardbridge depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.

Advice
Leave it or put it right?
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. Around Guardbridge, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Your questions about external mastic in Guardbridge
Can you help a landlord with a rental near Leuchars station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Guardbridge?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How long does the job take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
How we quote for external mastic
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- The number and length of the joints
- Mould in or behind the old joints
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
When you call or email, it’s useful to know:
- If someone has resealed it before
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
There’s no standard price list. Instead, your job gets its own clear quote. To get started, drop us a line at info@mrmastic.co.uk.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
Signs you need external mastic in Guardbridge
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Look out for any of the following:
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
For landlords with property near Leuchars station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
