Sand mastic for homes and businesses in Wilton
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on stone surrounds, period & listed homes and tenement windows, and common reasons people get in touch are patchy fillers round a sash window and tired mastic found when preparing windows for paint.
Mastic can only go onto a dry joint, so outside work in Wilton depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Your job is guaranteed for a year, as with all our work.

When to call us in Wilton
Timber frames move with the seasons. The movement cracks the mastic little by little.
People usually contact us when they notice something like this:
- Open joints round the window box
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
Schools such as Hawick High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

- 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.

Preparing for the visit

What sand mastic looks like in Wilton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Harden (about 3.1 miles west) nearby, there’s older building stock in the area around Wilton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Wilton Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
- Keep modern sealant off the mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Why deal with it now?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals 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.
