Sand mastic for homes and businesses in Innermessan
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. We work on period & listed homes, brick reveals and stone surrounds, and people most often call us about cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
All of our work is guaranteed for twelve months, in Innermessan and everywhere else we cover.

Quotes for sand mastic in Innermessan
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Working hours on commercial sites
- How much there is to do
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Asking for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Whether it has been sealed before
- Where the job is, and your postcode
- A few pictures by email, if you can
We quote each job on its own, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. 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.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Why book with us
- Experience in homes, commercial sites and hotels
- We leave the area clean and tidy
- 20+ years of sealant experience
- Every job guaranteed for a year

Innermessan questions
Will you come out to Innermessan?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does living near the coast affect sand mastic in Innermessan?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we are fully insured.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Innermessan homes and the weather
Innermessan is within about 1 mile of 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 the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Innermessan, as everywhere, sand mastic is only as good as the preparation behind it.

Signs you need sand mastic in Innermessan
Timber frames move with the seasons. The movement cracks the mastic little by little.
The most common problems we see are:
- Silicone on a period window that looks wrong
- Patchy fillers round a sash window
- Draughty sash windows at the surround
- Mastic that needs renewing before redecorating
If you let a flat or house near Stranraer station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- When the joint can take water or movement
- How much experience the applicator has
- What guarantee comes with the work
- Whether they seal over old material or remove it
Looking after it afterwards
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. Outdoor work around Innermessan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
