Sand Mastic in Longniddry
Our applicators work in Longniddry on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
The process
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours per window, depending on the condition of the joints. Around Longniddry, distance and access matter more than parking. 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.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Advice
How we handle sand mastic in Longniddry
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on tenement windows, brick reveals and timber door frames, and the jobs we see most are draughty sash windows at the surround and patchy fillers round a sash window.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

Aftercare tips
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Questions from Longniddry
Does living near the coast affect sand mastic in Longniddry?
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.
I let a flat near Longniddry station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you cover Longniddry?
Yes. We cover Longniddry and the rest of East Lothian. To book, send an email to info@mrmastic.co.uk.
Do you have insurance?
Yes. We’re fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
What affects the quote in Longniddry
Jobs vary more than people expect. What affects the quote:
- Any working-time requirements on site
- The type of sealant required
- How many rooms, windows or areas are involved
- The size of the job
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
Helping us quote
To make quoting easier, let us know:
- The rough size of the job
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- If someone has resealed it before
To get a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Longniddry homes and the weather
Longniddry is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Historic houses such as Gosford House, about 1.8 miles north, show how far back building around Longniddry goes. For landlords with property near Longniddry station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
