Sand mastic in Doonfoot, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on sash and case windows, brick reveals and stone surrounds, and people most often call us about mastic worn away on windows facing the weather and draughts and rain around sash boxes.
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.
You get a one-year guarantee, the same in Doonfoot as everywhere else we work.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How to look after the new joints
To keep the joints looking good and working properly:
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Sand mastic in Doonfoot: local notes
Doonfoot is within about 1 mile 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.
Rented homes near Ayr station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Wellington School? Then its window and door frames need their mastic kept sound, just like a home’s.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Outside jobs in Doonfoot need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Common questions in Doonfoot
Can you help a landlord with a rental near Ayr station?
Yes. We work for landlords and agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is sand mastic in a coastal place like Doonfoot any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is sand mastic better than silicone for my windows?
We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll talk you through it.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
