Upper Kilchattan Sand Mastic
Problem with your window and door surrounds in Upper Kilchattan? We cut out the old, prepare the joints and apply the right sealant.
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Draughty sash windows at the surround
Sand mastic in Upper Kilchattan, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you’re redecorating. Common call-outs are for a silicone bead on a sash window that spoils the look and gaps round a timber door in stone or brick, across timber door frames, brick reveals and tenement windows.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. Somewhere like Upper Kilchattan may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

Upper Kilchattan homes and the weather
Upper Kilchattan 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. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Homes close to St Cathan's Chapel include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. 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.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

- Whether work needs listed building consent
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

FAQs for Upper Kilchattan

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
