What sand mastic looks like in Dundee
Dundee 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. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Dundee’s older tenements are sandstone, and the city sits on the Firth of Tay, so the mastic around older windows and doors on walls facing the water can take plenty of weather.
Historic houses such as Camperdown House, about 2.5 miles west, show how far back building around Dundee goes, and older homes nearby need a sealant that suits their walls. Schools such as Scottish School of Contemporary Dance are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

About our sand mastic in Dundee
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We work on stone surrounds, tenement windows and period & listed homes, and common reasons people get in touch are mastic that needs renewing before redecorating and mastic round period door frames that has failed.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Dundee, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

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 call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Dundee, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common questions in Dundee
Does the coastal weather in Dundee affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Dundee station?
Yes, we work for letting agents and landlords. 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 any work starts.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Why it’s worth doing now in Dundee
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Dundee, damp can travel a long way before it shows.
Leaving a failed joint normally 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 for an honest opinion and a quote.
