Sand mastic in Kilchoan
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We are often asked to deal with mastic round period door frames that has failed and draughty sash windows at the surround, on stone surrounds, sash and case windows and period & listed homes.
Mastic can only go onto a dry joint, so outside work in Kilchoan depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We stand behind the work with a one-year guarantee.

Sand mastic in Kilchoan: local notes
Kilchoan is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
If you live in an older home near Ardnamurchan Parish Church of Scotland, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Kilchoan is in Highland. Every kind of property in Kilchoan is covered for sand mastic, old or new, large or small. Every job comes with our 12-month guarantee. Kilchoan is one of 253 places in Highland we cover for sand mastic.

Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

When it is not the sealant
New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Damaged stone surrounds
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
FAQs for Kilchoan
Does the coastal weather in Kilchoan affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you cover Kilchoan for sand mastic?
Yes, Kilchoan is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Kilchoan.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Kilchoan, along with the rest of our area.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
When to call us in Kilchoan
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
Look out for any of the following:
- Wind and rain getting in round a sash window
- Cement or filler used on old window joints that has cracked
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
In and around Kilchoan, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to a full day, depending on how many windows. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
