Sand Mastic in Lower Largo
Sand mastic across Lower Largo and nearby, with every bit of old sealant taken out first.
- Draughts and rain around sash boxes
- Open joints round the window box
- Tired mastic found when preparing windows for paint
Looking after it afterwards
Looking after new joints is easy:
- Ask a joiner to look at soft timber first
- Make sure water runs off the sill
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
About our sand mastic in Lower Largo
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. If you have crumbling sand mastic round a window and gaps where the frame meets the masonry, we can help, on timber door frames, period & listed homes and brick reveals alike.
In and around a place like Lower Largo, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
Big or small, you get the same one-year guarantee in Lower Largo and across Fife.

Questions from Lower Largo
Does living near the coast affect sand mastic in Lower Largo?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Leven station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Is the work guaranteed?
Our 12-month guarantee applies to all our work.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll talk you through it.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.

Different surfaces, different methods
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Lower Largo homes and the weather
Lower Largo 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Letting a property close to Leven station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Largo Parish Church And Churchyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
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. In an older home around Lower Largo, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Should I try it myself first?
What a professional job adds is preparation and the right 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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. In smaller Scottish places, parking is normally 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.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Tell us if parking is tricky
- Clear the area around the work
- Let us know about earlier repairs to the joints
