How we handle sand mastic in Balemartine
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you are dealing with gaps between timber frames and stone or brick and failed mastic on an exposed elevation, we can put it right.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

When to call us in Balemartine
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
These are the problems we’re asked about most:
- Gaps between timber frames and stone or brick
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Draughty sash windows at the surround
Around Balemartine, as everywhere, sand mastic is only as good as the preparation behind it.
What your quote should include
- Whether the sealant suits the joint
- Are they insured?
- Whether all the old sealant comes out first
- How long the guarantee is
Frames and glazing around Balemartine
Balemartine is within about 1 mile 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. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Whether the job is in Balemartine itself or nearby, the right material for each joint matters as much as a neat finish.

Common questions in Balemartine
Does the coastal weather in Balemartine 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. Walls facing the sea are generally the first to need attention.
Can you do sand mastic in Balemartine?
Yes. We work across all of Scotland, and Balemartine is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Surfaces we seal
- Timber door frames
- Stone surrounds
- Sash and case windows
- Brick reveals
- Period & listed homes
- Tenement windows
Keeping the joints in good condition
After the cure time, these simple habits help:
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Around Balemartine, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
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.
Quotes for sand mastic in Balemartine
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- Which sealant suits the joint
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
