Sand Mastic in Dyke
Traditional burnt sand mastic around sash and case windows and doors in stone and brick in Dyke, with a one-year guarantee on every job. Ask us for a quote.

Sand mastic in Dyke, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you have draughts and rain around sash boxes and tired mastic found when preparing windows for paint, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Dyke is planned around the weather. Let us know about access to every frame, including any upstairs.
We stand behind the work with a one-year guarantee.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Dyke, 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Surface by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
What sand mastic looks like in Dyke
Dyke is close to 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. Historic houses like Logie House (about 4.9 miles south) are a reminder that the area around Dyke has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Forres station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Signs you need sand mastic in Dyke
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they normally need raking out.
Keep an eye out for these signs:
- Draughts and rain around sash boxes
- Gaps where the frame meets the masonry
- Cracked mastic round a front door frame
- Window mastic to renew ahead of painting
Homes close to Dyke Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Common questions in Dyke
Is sand mastic in a coastal place like Dyke any different?
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 normally the first to need attention.
Do you cover smaller places like Dyke?
Yes. Dyke is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
