Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
How we handle sand mastic in Braehead
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We’re often asked to deal with mastic round period door frames that has failed and weathered mastic on the most exposed windows, on tenement windows, period & listed homes and sash and case windows.
Mastic can only go onto a dry joint, so outside work in Braehead depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Frames and glazing around Braehead
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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Letting a property close to Carstairs station? Then any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Broken panes
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes

Braehead questions
Is Braehead within the area you cover?
Yes, Braehead is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Carstairs station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How we quote for sand mastic
We quote each job individually. These are the things that affect it:
- The size of the job
- Any working-time requirements on site
- Whether there’s mould to deal with
- Which sealant suits the joint
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Helping us quote
You do not need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. Around Braehead, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
