How we handle sand mastic in Wellbank
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. Typical jobs include draughts and rain around sash boxes and gaps between timber frames and stone or brick, on period & listed homes, sash and case windows and tenement windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Sand mastic in Wellbank: local notes
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. Dundee sits on the north bank of the Tay, and much of its older housing is sandstone tenements, so the mastic around older windows and doors on walls facing the water can take plenty of weather.
Around Wellbank, as everywhere, sand mastic is only as good as the preparation behind it.

Your questions about sand mastic in Wellbank
Will you come out to Wellbank?
Yes, Wellbank is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Monifieth station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
How long does the job take?
A typical job takes anything from a few hours to a full day, depending on how many windows. Your quote will say how long we expect yours to take.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Landlords, agents and businesses in Wellbank
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside 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.
Why it’s worth doing now in Wellbank
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In an older home around Wellbank, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
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. You will know the price before we begin.

What we’re called out for in Wellbank
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they generally need raking out.
Any of these means the joints need attention:
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
For landlords with property near Monifieth station, any sash windows need sound mastic to keep draughts and rain out.
