Sand mastic for homes and businesses in Balerno
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on brick reveals, tenement windows and stone surrounds, and the jobs we see most are draughty sash windows at the surround and old cement repairs round a window that have failed.
Outdoor sealant needs a dry surface, so window work around Balerno is planned around the weather. Let us know about access to every frame, including any upstairs.
All our work comes with a 12-month guarantee, wherever you are in Edinburgh.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
What sand mastic looks like in Balerno
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Balerno Community High School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Curriehill station, any sash windows need sound mastic to keep draughts and rain out.

Is Balerno in your area for sand mastic?
Yes. We work across all of Scotland, and Balerno is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Where are you based?
We work from Crawley. We cover Balerno and the rest of Edinburgh.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.

Very little: the area around the joints is protected first, and we tidy up before we go.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Landlord and commercial work in Balerno
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
The process
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work generally takes a few hours for a single window, longer for several. Outside jobs in Balerno need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Clear the area around the work
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Do you need sand mastic in Balerno?
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
The most common problems we see are:
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
- Mastic that needs renewing before redecorating
In the older streets around St Mungo's Episcopal Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- Are they insured?
How to look after the new joints
Looking after new joints is easy:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Clear gutters so water does not pour onto the windows
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
