Questions from Drummore
Will you come out to Drummore?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Drummore affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Sand mastic in Drummore, done properly
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on sash and case windows, tenement windows and timber door frames, and common reasons people get in touch are gaps where the frame meets the masonry and wind and rain getting in round a sash window.
Mastic can only go onto a dry joint, so outside work in Drummore depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
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.

What we cannot put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Broken panes
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

How to look after the new joints
So the new joints stay in good condition:
- Do not paint over the new mastic
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
What we do, step by step
At the end, we look at the finished work together. The visit itself usually takes a few hours for a single window, longer for several, depending on the amount of work. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Sand mastic in Drummore: local notes
Drummore is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For an older house near a landmark such as Old Parish Church and Burial-Ground, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Drummore is about 16 miles south of Stranraer, in Dumfries and Galloway. Jobs in Drummore get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Drummore is one of 138 towns and villages in Dumfries and Galloway we cover for sand mastic.
Here we cover the DG9 postcode area for sand mastic. That includes homes and businesses on Harbour Terrace, Harbour Road and Ward Place. If you are just outside Drummore, we cover Port Logan (3 miles north-west), Ardwell (6 miles north), Sandhead (9 miles north), Stoneykirk (11 miles north) and Dunragit (13 miles north).

What affects the cost of sand mastic
We do not publish a price list. What we look at:
- Access and height
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The amount of work
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Where the job is, and your postcode
- Whether it has been sealed before
- The type of property
- Access, such as stairs, a lift or height

Surface by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Common problems we fix in Drummore
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Common reasons people contact us are:
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
- Window mastic to renew ahead of painting
- Gaps between timber frames and stone or brick
Around Drummore, as everywhere, sand mastic is only as good as the preparation behind it.
