About our sand mastic in Gilshochill

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on stone surrounds, period & listed homes and sash and case windows, and the jobs we see most are gaps round a timber door in stone or brick and a silicone bead on a sash window that spoils the look.

Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you’re in a tenement flat or a house in Gilshochill, the joint between frame and wall is what keeps the weather out.

We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

DIY sealant or a professional job?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Windows and doors in Gilshochill

Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.

If you let a flat or house near Gilshochill station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Historic houses such as Tenement House, about 2 miles south, show how far back building around Gilshochill goes, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as John Paul Academy, the mastic around its windows and doors needs looking after like any other building’s.

Your questions about sand mastic in Gilshochill

How do repairs to the shared parts of a tenement in Gilshochill get organised?

Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.

Do you work for landlords with property near Gilshochill station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.

What exactly is sand mastic?

It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can new sealant go over the old?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Can you replace silicone on a period window with sand mastic?

Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.

Is there any odour?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Do you guarantee sand mastic work?

Our 12-month guarantee applies to all our work.

What the job involves on each surface

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Period and listed homes

Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.

Leave it or put it right?

Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Private landlords in Gilshochill must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

The process

The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours for a single window, longer for several, and we explain the cure time before we leave. In a city area like Gilshochill, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Before we arrive

  • Keep children and pets away from the work area
  • Mention any parking rules near the property
  • Clear items away from the joints we’re working on

Advice

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Check with your local planning authority if your home is listed
  • Plan mastic work ahead of painting
  • Inspect the joints round the windows every year or so
  • Avoid heavy scraping on the mastic joint

Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.

Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

  • When we can work, for business premises

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.
