Nisbet homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near Crailing Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Sand mastic for homes and businesses in Nisbet
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for mastic round period door frames that has failed and tired mastic found when preparing windows for paint, on stone surrounds, period & listed homes and tenement windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. 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 one-year guarantee in Nisbet and across the Scottish Borders.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What affects the quote in Nisbet
There’s no set price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- What’s wrong with the joints now
- The type of property
- How many joints, rooms or windows are involved
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. We will send you a clear quote before any work starts.
Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep sills and gutters clear so water drains away
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Around Nisbet, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Advice
Do you need sand mastic in Nisbet?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Common reasons people contact us include:
- Crumbling sand mastic round a window
- Failed mastic on an exposed elevation
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
Around Nisbet, as everywhere, sand mastic is only as good as the preparation behind it.

Nisbet: your questions answered
Is sand mastic in Nisbet guaranteed?
All our work, in Nisbet and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Nisbet for sand mastic?
Yes. We work across all of Scotland, and Nisbet is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
How do I get a quote for sand mastic in Nisbet?
It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk and tell us what needs doing and where.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Work for landlords, hotels 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 that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
