How we handle sand mastic in West Barns
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on sash and case windows, tenement windows and timber door frames, and the jobs we see most are mastic round period door frames that has failed and failed mastic on an exposed elevation.
Mastic can only go onto a dry joint, so outside work in West Barns depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Frames and glazing around West Barns
West Barns 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In the older streets around Belhaven Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Sash and case windows

Before you book anyone
- Are they insured?
- Which sealant they’ll use, and why
- How long to leave it before use
- Is VAT in the price?
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
- Get any rot dealt with first
- Do not paint over the new mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere like West Barns may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In an older home around West Barns, damp from a failed joint can get into timber and plaster.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Common questions in West Barns
Does the coastal weather in West Barns 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. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Dunbar station?
Yes, we work for letting agents and landlords. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
