An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Timber door frames
Round a period front door, sand mastic gives the right look.
About our sand mastic in Kirkinner
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We’re often asked to deal with patchy fillers round a sash window and a silicone bead on a sash window that spoils the look, across period & listed homes, sash and case windows and timber door frames.
Mastic can only go onto a dry joint, so outside work in Kirkinner depends on the weather. Tell us about access to all the windows and doors, upstairs included.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Landlords, agents and businesses in Kirkinner
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams in Kirkinner and across Dumfries and Galloway. Several sites can be quoted together.
Windows and doors in Kirkinner
Kirkinner is close to 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Kirkinner, as everywhere, sand mastic is only as good as the preparation behind it.

FAQs for Kirkinner
Do you cover Kirkinner for sand mastic?
Yes. Our work covers the whole of Scotland, and Kirkinner is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Do you cover smaller places like Kirkinner?
Yes. Kirkinner is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Have rotten timber repaired before new mastic goes in
- Sort the mastic before the decorators arrive
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a single window, longer for several in most cases. Somewhere like Kirkinner may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
- Whether work needs listed building consent
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Common problems we fix in Kirkinner
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
The most common problems we see are:
- Failed mastic on an exposed elevation
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
For an older house near a landmark such as St Kennera Church and Churchyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
