Sand mastic in Ackergillshore, done properly
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on sash and case windows, brick reveals and timber door frames, and the jobs we see most are gaps between timber frames and stone or brick and modern sealant on a period surround.
Outdoor sealant needs a dry surface, so window work around Ackergillshore is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a place like Ackergillshore, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What the job involves on each surface
Stone surrounds
The stone is treated with care when the old mastic comes out.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.

Landlords and letting agents in Ackergillshore can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
How the visit works

Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.

Your questions about sand mastic in Ackergillshore
Can you help a landlord with a rental near Wick station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Does living near the coast affect sand mastic in Ackergillshore?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is it possible to take out silicone and use sand mastic instead?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you come to Ackergillshore?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Ackergillshore.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Are you insured?
Yes. Full insurance covers our work.
Frames and glazing around Ackergillshore
Ackergillshore 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’s hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Wick High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Inspect the joints round the windows every year or so
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
