Windows and doors in Marybank
Marybank is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
In and around Marybank, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Sand mastic in Marybank, done properly
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for crumbling sand mastic round a window and mastic that needs renewing before redecorating, on brick reveals, tenement windows and timber door frames.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, whatever its size.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Why it’s worth doing now in Marybank
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before work begins.
Why choose Mr Mastic in Marybank
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet
- Fully insured
- Tidy, careful work
What we’re called out for in Marybank
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
The problems people normally mention when they call are:
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
Whether the job is in Marybank itself or nearby, the right material for each joint matters as much as a neat finish.
What to look for in a quote
- What preparation is included
- How long to leave it before use
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- Mould in or behind the old joints
- The size of the job
- The product the joint needs
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
When you call or email, these details help:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- The problem you’ve noticed
- The type of property
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, email us at info@mrmastic.co.uk.
Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Sashes that rattle, stick or will not open
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
