About our sand mastic in Walkerburn
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you have a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed, we can put it right.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Big or small, you get the same 12-month guarantee in Walkerburn and across the Scottish Borders.

Common questions in Walkerburn
Can you do sand mastic in Walkerburn?
Yes, Walkerburn is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
What guarantee comes with sand mastic in Walkerburn?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
How do I get a quote for sand mastic in Walkerburn?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

When to call us in Walkerburn
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Most people get in touch after spotting something like this:
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Cracked mastic round a front door frame
Around Walkerburn, as everywhere, sand mastic is only as good as the preparation behind it.
Before you book anyone
- Is the old sealant removed completely?
- How the colour is chosen
- What happens if the job turns out different
- Whether they’re fully insured
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- Which sealant suits the joint
- Whether there’s mould to deal with
- The number of rooms or windows
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Photos by email, if that is easy
- What’s wrong with the joints now
- Whether it has been sealed before
- The type of property
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, drop us a line at info@mrmastic.co.uk.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Sashes that rattle, stick or won’t open
- Decisions on consent for listed homes
- Putty and glazing repairs
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

Historic houses like Peel House (about 4.6 miles east) are a reminder that the area around Walkerburn has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Walkerburn Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a single window, longer for several. Outside jobs in Walkerburn need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
