How we quote for sand mastic
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The number of rooms or windows
- Any mould that needs treating
- Whether the work is at height
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
What we need to know
When you contact us, it’s useful to know:
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
How we handle sand mastic in Leslie
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. Typical jobs include weathered mastic on the most exposed windows and mastic that needs renewing before redecorating, across sash and case windows, timber door frames and stone surrounds.
In and around a place like Leslie, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All our work is covered by a 12-month guarantee, wherever you are in Fife.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Outdoor work around Leslie depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

What sand mastic looks like in Leslie
Sash and case windows are common in older Scottish homes, 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.
Letting a property close to Markinch station? Then any sash windows need sound mastic to keep draughts and rain out. Schools such as Glenwood High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Trinity Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How long does sand mastic take?
A typical job takes a few hours per window, depending on the condition of the joints, including the preparation. Your quote will say how long we expect yours to take.
