- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Gaps round a timber door in stone or brick
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Outdoor work around Arisaig 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Sand mastic for homes and businesses in Arisaig
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have patchy fillers round a sash window and modern sealant on a period surround, we can put it right.
Outdoor sealant needs a dry surface, so window work around Arisaig is planned around the weather. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard.

When to call us in Arisaig
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Open joints round the window box
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
Rented homes near Arisaig station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before booking
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
- When the joint can take water or movement
- How long the guarantee is
How the job changes by surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Common questions in Arisaig
Does the coastal weather in Arisaig 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 usually the first to need attention.
Is Arisaig within the area you cover?
Yes. Arisaig is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
What else we do in Arisaig
Looking after it afterwards
Looking after new joints is easy:
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

Sand mastic in Arisaig: local notes
Arisaig is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Roman Catholic Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
