Upper Largo Sand Mastic
We cover Upper Largo for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
Sand mastic in Upper Largo
We work across Upper Largo renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. Typical jobs include a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed, across period & listed homes, timber door frames and stone surrounds.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job is covered by a 12-month guarantee, wherever you are in Fife.

Signs you need sand mastic in Upper Largo
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
People usually contact us when they notice one of these:
- Patchy fillers round a sash window
- Mastic round period door frames that has failed
- Open joints round the window box
- Mastic worn away on windows facing the weather
For an older house near a landmark such as Largo Parish Church And Churchyard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. Around Upper Largo, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Keeping the joints in good condition
After the cure time, these simple habits help:
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Your questions about sand mastic in Upper Largo
Can you help a landlord with a rental near Leven station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Does the coastal weather in Upper Largo affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you guarantee sand mastic work?
All our work has a 12-month guarantee.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We will confirm how long when we quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why act early in Upper Largo
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a place like Upper Largo, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

- 12-month guarantee on every job
- Rated 4.9 stars on Google
- Anti-fungal sanitary silicone in wet areas

Sand mastic in Upper Largo: local notes
Upper Largo is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Letting a property close to Leven station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the 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 doesn’t work out, we can still put it right.
