Advice
Sand mastic in Tranent
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you are dealing with mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look, we can help.
Mastic can only go onto a dry joint, so outside work in Tranent depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Honest limits
It helps to know what we cannot do:
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
- Timber that has rotted
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Sash and case windows
- Tenement windows
- Stone surrounds
- Period & listed homes
- Timber door frames
- Brick reveals
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a place like Tranent, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.

Your questions about sand mastic in Tranent
Does living near the coast affect sand mastic in Tranent?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Tranent?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How much does sand mastic cost in Tranent?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.

Tranent is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Hamilton House, about 1.4 miles north-west, is one of the historic houses in the wider area around Tranent. Letting a property close to Prestonpans station? Then any sash windows need sound mastic to keep draughts and rain out.

Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials.
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
What we’re called out for in Tranent
Timber frames move with the seasons. The movement cracks the mastic little by little.
If you can see any of these, it’s time to have the joints looked at:
- Tired mastic found when preparing windows for paint
- Patchy fillers round a sash window
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
For site and facilities teams at buildings such as Ross High School, larger buildings have plenty of frames, and the mastic around each one ages.
