About our sand mastic in Carradale
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on tenement windows, timber door frames and sash and case windows, and the jobs we see most are a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Carradale: your questions answered
Can you do sand mastic in Carradale?
Yes. Our work covers the whole of Scotland, and Carradale is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Does the coastal weather in Carradale affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Can you quote for more than one area?
Yes. Just list everything you need.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
How the job changes by surface
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Sand mastic in Carradale: local notes
Carradale is close to 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In the older streets around Saddell Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Carradale
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
These are the problems we’re asked about most:
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
In and around Carradale, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Whether they seal over old material or remove it
- The length of the guarantee
- Is VAT in the price?
- What product goes in the joint
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to a full day, depending on how many windows. 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 the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
