Windows and doors in Inkerman
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 sound outside sealant is part of that.
If you let a flat or house near Paisley St James station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we handle sand mastic in Inkerman
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We work on period & listed homes, tenement windows and timber door frames, and common reasons people get in touch are crumbling sand mastic round a window and mastic worn away on windows facing the weather.
Mastic can only go onto a dry joint, so outside work in Inkerman depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months, in Inkerman and everywhere else we cover.

Inkerman questions
Can you help a landlord with a rental near Paisley St James station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Is Inkerman within the area you cover?
Yes. Inkerman is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
What sealant work cannot fix
We will always be straight with you, so here’s what sealant can’t fix:
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

What the job involves on each surface
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
What we are called out for in Inkerman
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.
The problems people generally mention when they call include:
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
Managing a site like Castlehead High School? Then its window and door frames need their mastic kept sound, just like a home’s.

How it works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a single window, longer for several, including the tidy-up. Outdoor work around Inkerman 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 look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Advice
Aftercare tips
So the new joints stay in good condition:
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
- Look over the window mastic once a year
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

Why act early in Inkerman
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
