How we handle sand mastic in Macmerry
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on sash and case windows, stone surrounds and period & listed homes, and the jobs we see most are old cement repairs round a window that have failed and weathered mastic on the most exposed windows.
Outdoor sealant needs a dry surface, so window work around Macmerry is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All our work is covered by our one-year guarantee, wherever you are in East Lothian.

How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any tricky access
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts

Why act early in Macmerry
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
Why book with us
- Full insurance on every job
- A 12-month guarantee on all work
- Trusted Arbo and Everbuild sealants
- Any old sealant cut out fully, not covered over

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the quote in Macmerry
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- The old material and how stubborn it is
- Working hours on commercial sites
- The number and length of the joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- A few photos by email, if you can
For a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
Signs you need sand mastic in Macmerry
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Draughts and rain around sash boxes
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window

Macmerry: your questions answered
Can you help a landlord with a rental near Longniddry station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Will you come out to Macmerry?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you replace silicone on a period window with sand mastic?
Generally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What we can’t put right
To be straight with you, some problems need a different trade:
- Decisions on consent for listed homes

Sand mastic in Macmerry: local notes
Macmerry is within about 3 miles of 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Longniddry station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Ross High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
