DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a tenement in Scotstoun, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.

Scotstoun questions
Who arranges sealant work on the shared parts of a tenement in Scotstoun?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
I let a flat near Scotstounhill station. Can you help?
Yes. We work for landlords and agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
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.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Do you work in Scotstoun?
Yes. We work in Scotstoun, as part of our work across South East England, London and Scotland. To book, email us at info@mrmastic.co.uk.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
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.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Frames and glazing around Scotstoun
Scotstoun 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. With historic houses such as Tenement House (about 3.2 miles east) nearby, there’s older building stock in the area around Scotstoun as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Scotstounhill station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Scotstoun East Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Scotstoun Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Go gently near the mastic when preparing windows
- Ask us before painting near the mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
