Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Sand mastic in Tarbert, 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 a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on stone surrounds, brick reveals and sash and case windows, and people most often call us about mastic round period door frames that has failed and open joints round the window box.
Mastic can only go onto a dry joint, so outside work in Tarbert depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You are covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. Outdoor work around Tarbert depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

Related advice
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Tarbert questions
Can you do sand mastic in Tarbert?
Yes. We work across all of Scotland, and Tarbert is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Is sand mastic in a coastal place like Tarbert any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.

What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- The size of the job
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Signs you need sand mastic in Tarbert
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they normally need raking out.

- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
For jobs in and around Tarbert, choosing the right material for each joint is as important as a tidy finish.

Frames and glazing around Tarbert
Tarbert 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 sound outside sealant is part of that.
Around Tarbert, as everywhere, sand mastic is only as good as the preparation behind it.
