Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
Sand mastic in Kelvingrove
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. We’re often asked to deal with mastic dropping out of the joint and cracked mastic round a front door frame, on stone surrounds, sash and case windows and tenement windows.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you’re in a tenement flat or a house in Kelvingrove, the joint between frame and wall is what keeps the weather out.
All of our work is guaranteed for twelve months.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Make sure water runs off the sill
- Keep modern sealant off the mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
What happens if it’s left?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Wind-driven rain gets into any failed joint on the outside of a city building, and in Kelvingrove, damp can spread through stone and plaster before anyone sees it.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas

Kelvingrove homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Letting a property close to Exhibition Centre station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Glasgow Gaelic School, its window and door frames need their mastic kept sound, just like a home’s.

What we are called out for in Kelvingrove
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they usually need raking out.
It’s worth asking for a quote if you see:
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
Homes close to Kelvingrove Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Kelvingrove
How do repairs to the shared parts of a tenement in Kelvingrove get organised?
It normally 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.
Do you work for landlords with property near Exhibition Centre station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you have insurance?
Yes. Full insurance covers our work.
How much does sand mastic cost in Kelvingrove?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
