Westerton questions
How is work on the outside of a tenement in Westerton usually arranged?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Westerton station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
How long will you be here?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll tell you how long to expect.
How we handle sand mastic in Westerton
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We’re often asked to deal with silicone on a period window that looks wrong and old cement repairs round a window that have failed, across tenement windows, period & listed homes and timber door frames.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you are in a tenement flat or a house in Westerton, the joint between frame and wall is what keeps the weather out.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What we are called out for in Westerton
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
If you can see any of these, it’s time to have the joints looked at:
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
If you live in an older home near New Kilpatrick UP Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- The length of the guarantee
- Who turns up on the day
- Are they insured?
- Whether all the old sealant comes out first

Why act early in Westerton
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Westerton, damp can travel a long way before it shows.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What you get with us
- We never seal over old sealant
- Domestic, commercial and hotel work
- Neat joints and a tidy finish
- Quality sealants from Arbo and Everbuild

The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job normally takes a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Westerton, tell us the floor, how the door entry system works and where we can park nearby.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Windows and doors in Westerton
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, often through a property factor. Windows usually belong to the flat, but the title deeds have the final say. 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.
For landlords with property near Westerton station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Knightswood Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.
