How we handle sand mastic in Timsgarry
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on stone surrounds, tenement windows and period & listed homes, and people most often call us about mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
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.
All of our work is guaranteed for twelve months.

Why deal with it now?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Timsgarry, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Do not run silicone over sand mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. For a place like Timsgarry, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
How to get a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, drop us a line at info@mrmastic.co.uk.

Signs you need sand mastic in Timsgarry
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
For an older house near a landmark such as Uig Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods

Brick reveals
We rake out the old mastic and pack deep voids before pointing.
What sand mastic looks like in Timsgarry
Timsgarry 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Timsgarry, as everywhere, sand mastic is only as good as the preparation behind it.
