Sand mastic in Clivocast, done properly
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, tenement windows and sash and case windows, and people most often call us about old cement repairs round a window that have failed and gaps between timber frames and stone or brick.
Mastic can only go onto a dry joint, so outside work in Clivocast depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job.

What the job involves on each surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Common problems we fix in Clivocast
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
Signs it’s time to call us include:
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Window mastic to renew ahead of painting
- Mastic dropping out of the joint
For an older house near a landmark such as Uyeasound Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Access and height
- How many areas need sealing
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
To help us quote quickly, please include:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- The address or postcode of the job
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Find out about consent before window work on a listed home
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Have rotten timber repaired before new mastic goes in
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
FAQs for Clivocast
Will you come out to Clivocast?
Yes, Clivocast is covered. We work across all of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Clivocast any different?
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.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How much does sand mastic cost in Clivocast?
Every job is different, so each one gets its own quote. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll talk you through it.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Related advice
Why it’s worth doing now in Clivocast
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In an older home around Clivocast, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Clivocast homes and the weather
Clivocast is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s 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, often pointed into the wall with traditional sand mastic.
In and around Clivocast, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
