Appin: your questions answered
Does the coastal weather in Appin affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover Appin for external mastic?
Yes, Appin is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
External mastic in Appin
On houses, flats and commercial buildings across Appin, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have water getting into walls through failed joints and cracked joints where brick meets render or frames, we can put it right, whatever the surface.
External sealant needs dry surfaces, so outdoor work around Appin is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Big or small, it’s backed by our one-year guarantee.

Advice
Why act early in Appin
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. 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.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

External mastic in Appin: local notes
Appin is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Appin is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
In and around Appin, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Appin is in Argyll and Bute. Appin gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Appin is one of 118 places in Argyll and Bute where we work for external mastic. You can also see our page for Glasgow, about 64 miles away.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check external joints each spring
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we’ve said otherwise
- Make sure movement joints aren’t pointed over
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
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.
What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- Any working-time requirements on site
- How many areas need sealing
- The product the joint needs
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Where the property is
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand.
When to call us in Appin
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People usually contact us after spotting something like this:
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
Homes close to Appin Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
