Frames and glazing around New Winton
New Winton is within about 3 miles 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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you let a flat or house near Prestonpans station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Ross High School, the mastic around its windows and doors needs looking after like any other building’s.

About our sand mastic in New Winton
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include mastic round period door frames that has failed and old sand mastic that has cracked, crumbled or fallen out, across brick reveals, timber door frames and tenement windows.
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 are covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Get any rot dealt with first
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

What else we do in New Winton
Leave it or put it right?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. In a place like New Winton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why New Winton customers choose us
- We never seal over old sealant
- Tidy, careful work
- Quality sealants from Arbo and Everbuild
- ARBOMaster approved applicator

What we’re called out for in New Winton
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Any of these means the joints need attention:
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
Historic houses such as Hamilton House, about 2.9 miles north-west, show how far back building around New Winton goes.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The process
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. All told, the work takes anything from a few hours to a full day, depending on how many windows. Around New Winton, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Tell us about any water getting in
