External mastic in Fearnan
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Common call-outs are for rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint, across copings & trims, concrete & block and façade panels.
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.
Your job is guaranteed for a year, as with all our work.

Your questions about external mastic in Fearnan
Is there a guarantee on external mastic in Fearnan?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Fearnan within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
What we’re called out for in Fearnan
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Keep an eye out for these signs:
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
- Failed seals between different materials
- Joints where the bead has come unstuck
Around Fearnan, as everywhere, external mastic is only as good as the preparation behind it.

Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

What affects the quote in Fearnan
Call for a quick quote. The main things that affect it are:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- The type of sealant required
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
When you call or email, it’s useful to know:

- Where the job is, and your postcode
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.

Aftercare tips
Looking after new joints is easy:
- Deal with leaking gutters that soak the joints below
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at every joint and agree a colour to suit the wall.
- 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.
How to prepare
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
