How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Somewhere like Sandhaven 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.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

Advice
Sand mastic for homes and businesses in Sandhaven
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. Common call-outs are for gaps between timber frames and stone or brick and modern sealant on a period surround, on stone surrounds, tenement windows and brick reveals.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Sandhaven: your questions answered
Does the coastal weather in Sandhaven affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you cover smaller places like Sandhaven?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
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 advise.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Signs you need sand mastic in Sandhaven
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they usually need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Mastic dropping out of the joint
If you look after a building such as Fraserburgh Academy, its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Sandhaven
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Sandhaven, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What sand mastic looks like in Sandhaven
Sandhaven 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
In and around Sandhaven, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
