Sand mastic in An Luirg
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you are dealing with gaps between timber frames and stone or brick and cracked mastic round a front door frame, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job comes with our 12-month guarantee, wherever you are in Highland.

Common questions in An Luirg
Do you cover smaller places like An Luirg?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Lairg station?
Yes. We work for landlords and letting agents as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover An Luirg and the rest of Highland.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
An Luirg homes and the weather
An Luirg is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In and around An Luirg, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Local landmarks in An Luirg
The nearest railway station is Lairg station, roughly 1.6 miles south of the centre. Not far away are Loch Dola and The Ord.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
- Do not run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why act early in An Luirg
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. In an older home around An Luirg, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why An Luirg clients choose us
- Tidy, careful work
- Arbo and Everbuild products
- ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work

How the job changes by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
How we quote for sand mastic
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Mould in or behind the old joints
- When we can work, for business premises
Combining jobs into one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- How we’d reach the joints
- Where the job is, and your postcode
- Any previous sealing or DIY work
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Do you need sand mastic in An Luirg?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Keep an eye out for these signs:
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
If you let a flat or house near Lairg station, any sash windows need sound mastic to keep draughts and rain out.
