Sand mastic in Kirkton
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, timber door frames and stone surrounds, and common reasons people get in touch are cement or filler used on old window joints that has cracked and a silicone bead on a sash window that spoils the look.
Mastic can only go onto a dry joint, so outside work in Kirkton depends on the weather. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

How we quote for sand mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- Mould in or behind the old joints
- Access and height
- The old material and how stubborn it is
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
Asking for a quote
To help us quote quickly, let us know:
- Any access issues, like height or stairs
- The problem you’ve noticed
- Where the job is, and your postcode
- Whether it has been sealed before
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear price.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Around Kirkton, water from a failed joint in an older stone home can soak into timber and plaster.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Kirkton
- Homes, businesses and hotels
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work
- Neat joints and a tidy finish
Looking after it afterwards
So the new joints stay in good condition:
- Plan mastic work ahead of painting
- Clear gutters so water doesn’t pour onto the windows
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for a single window, longer for several. Outdoor work around Kirkton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Let us know about parking restrictions

Sand mastic in Kirkton: local notes
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. 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.
Homes close to Kirkmahoe Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you cover Kirkton for sand mastic?

Do you guarantee sand mastic work?
Every job comes with our one-year guarantee.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames usually get a flexible sealant.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Are you insured?
Yes. Mr Mastic is fully insured.
What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
