How we handle sand mastic in Watten
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. Typical jobs include mastic that needs renewing before redecorating and gaps round a timber door in stone or brick, across tenement windows, sash and case windows and period & listed homes.
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.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Watten homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Watten, as everywhere, sand mastic is only as good as the preparation behind it.

What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. 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.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What we’re called out for in Watten
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
Common reasons people contact us are:
- Mastic dropping out of the joint
- Window mastic to renew ahead of painting
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
For jobs in and around Watten, choosing the right material for each joint is as important as a tidy finish.

What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. Somewhere like Watten may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Watten questions
Is Watten within the area you cover?
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.
Is there a guarantee on sand mastic in Watten?
All our work, in Watten and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
