External mastic in Breasclete, done properly
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. Typical jobs include rigid filler in a joint that should flex and leaking joints around cladding and façade panels, on copings & trims, joints between brick and frames and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Breasclete depends on the weather. Tell us how to reach each wall, gutter and roofline.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

External mastic in Breasclete: local notes
Breasclete is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 failed outside joints work against that.
In and around Breasclete, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Breasclete (Gaelic: Breascleit) is in Na h-Eileanan Siar. Across the HS2 area, we can carry out external mastic at your property. Breasclete is one of 87 places in Na h-Eileanan Siar where we work for external mastic.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Quotes for external mastic in Breasclete
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- The number and length of the joints
- Which sealant suits the joint
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
When you call or email, it’s useful to know:
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- The rough size of the job
- The type of property
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.
Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.

Why it’s worth doing now in Breasclete
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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
Looking after new joints is easy:
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Point out the joints to other trades
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What we are called out for in Breasclete
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
People normally contact us when they notice one of these:
- Plants rooting in failed movement joints
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
Whether the job is in Breasclete itself or nearby, the right material for each joint matters as much as a neat finish.

FAQs for Breasclete
Can you do external mastic in Breasclete?
Yes, Breasclete is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Breasclete?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
How long does external mastic take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will say how long yours will take.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Outside jobs in Breasclete need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Clear the area around the work
