Rigside Sand Mastic
Window and door surrounds in Rigside need attention? We cut out the old, prepare the joints and apply the right sealant.
- Draughts and rain around sash boxes
- Mastic worn away on windows facing the weather
- Cracked mastic round a front door frame
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
How we handle sand mastic in Rigside
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you’re dealing with silicone on a period window that looks wrong and crumbling sand mastic round a window, we can help, whatever the surface.
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.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Landlord and commercial work in Rigside
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Rigside 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.
For jobs in and around Rigside, choosing the right material for each joint is as important as a tidy finish.

How it works
Before we leave, we go over the finished joints with you. The visit itself generally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In smaller Scottish places, parking is usually 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.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Rigside questions
Is Rigside within the area you cover?
Yes, Rigside is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do sand mastic in Rigside?
Yes. Our work covers the whole of Scotland, and Rigside is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Is it possible to take out silicone and use sand mastic instead?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will advise.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
When to call us in Rigside
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between timber frames and stone or brick
- Silicone on a period window that looks wrong
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint
Around Rigside, as everywhere, sand mastic is only as good as the preparation behind it.

Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
