Sand mastic in Gretna Green
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for mastic round period door frames that has failed and mastic dropping out of the joint, across brick reveals, period & listed homes and sash and case windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Big or small, it’s backed by our 12-month guarantee.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Gretna Green homes and the weather
Gretna Green 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. 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 live in an older home near Old Church and Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Gretna Green station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Questions from Gretna Green
Do you cover smaller places like Gretna Green?
Yes. Gretna Green 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.
Does living near the coast affect sand mastic in Gretna Green?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is consent needed for window work on a listed home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Leave it or put it right?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
