When to call us in West Side
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:
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
Around West Side, as everywhere, sand mastic is only as good as the preparation behind it.
Before you book anyone
- How the joint is cleaned and prepared
- What happens if the job turns out different
- What the cure time is
- Whether all the old sealant comes out first
Sand mastic for homes and businesses in West Side
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you have gaps round a timber door in stone or brick and cement or filler used on old window joints that has cracked, we can put it right, on sash and case windows, period & listed homes and tenement windows alike.
Outdoor sealant needs a dry surface, so window work around West Side is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Why act early in West Side
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 damp in stone or harled walls takes a long time to dry once water gets behind a joint.
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. We give a clear quote before we start.

West Side questions
Is sand mastic in a coastal place like West Side any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like West Side?
Yes, West Side is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in West Side.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Is sand mastic better than silicone for my windows?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

How it works
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours per window, depending on the condition of the joints. Outdoor work around West Side depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts

Different surfaces, different methods
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep modern sealant off the mastic
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Frames and glazing around West Side
West Side is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
For jobs in and around West Side, choosing the right material for each joint is as important as a tidy finish.
