Your questions about sand mastic in Dunmore
Is sand mastic in a coastal place like Dunmore any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you cover smaller places like Dunmore?
Yes. Dunmore is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later, and we will tell you what to expect.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together.
How we handle sand mastic in Dunmore
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We are often asked to deal with open joints round the window box and a silicone bead on a sash window that spoils the look, across sash and case windows, tenement windows and period & listed homes.
Mastic can only go onto a dry joint, so outside work in Dunmore depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Leave it or put it right?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In a place like Dunmore, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Sand mastic in Dunmore: local notes
Dunmore is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Alloa station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Airth Parish Church and Churchyard, the joint between an old wall and a newer frame is normally the first place rain gets in.

Related advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Common problems we fix in Dunmore
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
Common reasons people contact us are:
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
For site and facilities teams at buildings such as Alloa Academy, its window and door frames need their mastic kept sound, just like a home’s.

- Whether you can choose the colour

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Plan mastic work ahead of painting
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
