- Tired mastic found when preparing windows for paint
- Gaps round a timber door in stone or brick
- Mastic worn away on windows facing the weather
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Sand mastic in Ardchattan
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you have old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, we can put it right.
Outdoor sealant needs a dry surface, so window work around Ardchattan is planned around the weather. Let us know about access to every frame, including any upstairs.
Our work is backed for twelve months, in Ardchattan and everywhere else we cover.

FAQs for Ardchattan
Do you cover smaller places like Ardchattan?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Ardchattan?
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 generally the first to need attention.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We will give you a better idea when we quote.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together.
Can you quote for more than one area?
Yes. Just list everything you need.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. 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.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

When to call us in Ardchattan
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Keep an eye out for these signs:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
Rented homes near Connel Ferry station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- What product goes in the joint
- Are they insured?
- How the surfaces are prepared before sealing
- Who turns up on the day
DIY versus a professional finish
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 does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sand mastic in Ardchattan: local notes
Ardchattan 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Ardchattan Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
