FAQs for Dumbiedykes
Does the coastal weather in Dumbiedykes affect outside sealant?
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 usually the first to need attention.
How do repairs to the shared parts of a tenement in Dumbiedykes get organised?
Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Sand mastic in Dumbiedykes
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We’re often asked to deal with tired mastic found when preparing windows for paint and mastic round period door frames that has failed, on period & listed homes, timber door frames and sash and case windows.
Dumbiedykes is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Dumbiedykes, damp can travel a long way before it shows.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Anti-fungal silicone where joints get wet
- Approved under the ARBOMaster scheme
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check the mastic when you check the paintwork
- Keep sills and gutters clear so water drains away
- Don’t paint over the new mastic
- Avoid heavy scraping on the mastic joint
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Masonry that needs repairing
- Sashes that rattle, stick or will not open
- Decayed frames that need repair
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

What sand mastic looks like in Dumbiedykes
Dumbiedykes is close to 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look.
If you let a flat or house near Edinburgh Waverley station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Whitefoord House, about 0.2 miles north, is one of the historic houses in the wider area around Dumbiedykes, and older homes nearby need a sealant that suits their walls.

Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Common problems we fix in Dumbiedykes
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
Any of these means the joints need attention:
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Gaps round a timber door in stone or brick
- Mastic that needs renewing before redecorating
For site and facilities teams at buildings such as Old Royal High School, its window and door frames need their mastic kept sound, just like a home’s.
