Sand mastic in Innerwick, done properly
We work across Innerwick renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on tenement windows, stone surrounds and period & listed homes, and common reasons people get in touch are failed mastic on an exposed elevation and draughty sash windows at the surround.
Mastic can only go onto a dry joint, so outside work in Innerwick depends on the weather. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How to look after the new joints
To keep the joints looking good and working properly:
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
What happens on the day
The work is kept neat and contained to the area we’re working on. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Somewhere like Innerwick may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- 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

Related advice
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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing

Common questions in Innerwick
Do you cover smaller places like Innerwick?
Yes, Innerwick is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Innerwick?
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 it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is the work guaranteed?
Our 12-month guarantee covers every job.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Can old silicone round a sash window be swapped for sand mastic?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Frames and glazing around Innerwick
Innerwick is within about 2 miles of 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. 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.
Rented homes near Dunbar station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Innerwick Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the cost of sand mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- Mould in or behind the old joints
- How many areas need sealing
- The old material and how stubborn it is
- The number and length of the joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What to tell us for a quote
