How we handle sand mastic in Gallowgate
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Common call-outs are for wind and rain getting in round a sash window and cracked mastic round a front door frame, across period & listed homes, timber door frames and tenement windows.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. Whether you are in a tenement flat or a house in Gallowgate, the joint between frame and wall is what keeps the weather out.
You get a one-year guarantee, the same in Gallowgate as everywhere else we work.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
- Make sure water runs off the sill
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Parking in city streets around Gallowgate can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Let us know if you’ve seen damp or leaks

FAQs for Gallowgate
I let a flat near Bellgrove station. Can you help?
Yes, we work for landlords and letting 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 work begins.
How do repairs to the shared parts of a tenement in Gallowgate get organised?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Do you come to Gallowgate?
Yes. We cover Gallowgate, as part of our work across South East England, London and Scotland. To book, send an email to info@mrmastic.co.uk.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
When to call us in Gallowgate
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
If you can see any of these, it’s time to have the joints looked at:
- Patchy fillers round a sash window
- Silicone on a period window that looks wrong
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
Historic houses such as Provand's Lordship, about 0.9 miles north-west, show how far back building around Gallowgate goes, and older homes nearby need a sealant that suits their walls.
Questions to ask before booking
- Whether VAT is included
- Which colour the sealant will be
- How hidden problems are handled
- Whether all the old sealant comes out first
What happens if it’s left?
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. For landlords in Gallowgate, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Gallowgate homes and the weather
Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows generally belong to the flat, but the title deeds have the final say. Gallowgate is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Managing a site like St Mungo's Academy? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Bellgrove station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
