How we handle sand mastic in Benderloch
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. If you have gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, we can put it right, on brick reveals, period & listed homes and timber door frames alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Different surfaces, different methods
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.
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. The work usually takes a few hours per window, depending on the condition of the joints. For a place like Benderloch, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Advice
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Have rotten timber repaired before new mastic goes in
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Windows and doors in Benderloch
Benderloch 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Benderloch, as everywhere, sand mastic is only as good as the preparation behind it.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

When to call us in Benderloch
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Common reasons people contact us are:
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
