Why it’s worth doing now in Shiskine
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Shiskine, water from a failed joint in an older stone home can soak into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Sand mastic in Shiskine
We work across Shiskine renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. Typical jobs include silicone on a period window that looks wrong and old cement repairs round a window that have failed, across period & listed homes, tenement windows and timber door frames.
Mastic can only go onto a dry joint, so outside work in Shiskine depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Your job is guaranteed for a year, as with all our work.

Landlord and commercial work in Shiskine
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Shiskine questions
Will you come out to Shiskine?
Yes. Shiskine is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect sand mastic in Shiskine?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
How long will you be here?
A typical job takes a few hours per window, depending on the condition of the joints. We’ll confirm how long when we quote.
How much does sand mastic cost in Shiskine?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Should I check with the council before work on a listed or conservation-area 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.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Period and listed homes
A traditional finish suits a period property.
What we’re called out for in Shiskine
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
People normally contact us when they notice one of these:
- Wind and rain getting in round a sash window
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
In the older streets around St Molios Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- What guarantee comes with the work
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
Looking after it afterwards
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. Somewhere like Shiskine 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.
- First we agree which joints need doing.
- 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.
How to prepare
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Frames and glazing around Shiskine
Shiskine 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. 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.
Around Shiskine, as everywhere, sand mastic is only as good as the preparation behind it.
