Sand mastic for sash & case windows in St Quivox, South Ayrshire
Problem with your window and door surrounds in St Quivox? We cut out the old, prepare the joints and apply the right sealant.
- Draughts and rain around sash boxes

Sand mastic for homes and businesses in St Quivox
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with modern sealant on a period surround and patchy fillers round a sash window, across sash and case windows, brick reveals and stone surrounds.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Advice
What we are called out for in St Quivox
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
It’s worth asking for a quote if you see:
- Modern sealant on a period surround
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
Managing a site like Prestwick Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- When the joint can take water or movement
- Is VAT in the price?
- Whether the sealant suits the joint
- Which colour the sealant will be
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Common questions in St Quivox
Can you help a landlord with a rental near Newton-On-Ayr station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like St Quivox?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one 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.
Frames and glazing around St Quivox
St Quivox is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
For landlords with property near Newton-On-Ayr station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as St Quivox Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Aftercare tips
To keep the joints looking good and working properly:
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
