What sand mastic looks like in Thomshill
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Birnie Kirk include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Elgin High School, its window and door frames need their mastic kept sound, just like a home’s.
Thomshill is about 3 miles south of Elgin, in Moray. Thomshill gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Thomshill is one of 58 places in Moray where we work. Our Aberdeen page covers work nearby, about 54 miles away.

How we handle sand mastic in Thomshill
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have silicone on a period window that looks wrong and old cement repairs round a window that have failed, we can put it right, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Thomshill is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the quote in Thomshill
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Which sealant suits the joint
- Working hours on commercial sites
- The size of the job
- How many areas need sealing
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Whether it has been sealed before
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details and send photos if you have them.
Surface by surface
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why us?
- Fully insured
- A 12-month guarantee on all work

Signs you need sand mastic in Thomshill
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
Rented homes near Elgin station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

- Which sealant they’ll use, and why

How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in Thomshill need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We look at the surrounds with you and agree the joints to renew.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t run silicone over sand mastic
- Renew mastic before redecorating the windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
