How we handle sand mastic in Nethercraigs

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for mastic dropping out of the joint and failed mastic on an exposed elevation, across period & listed homes, stone surrounds and brick reveals.

In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Nethercraigs.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Nethercraigs: your questions answered

Can you do sand mastic in Nethercraigs?

Yes, Nethercraigs is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.

Do you work for landlords with property near Corkerhill station?

Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.

Should I check with the council before work on a listed or conservation-area home?

Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.

What exactly is sand mastic?

Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.

Where do you work from?

We work from Crawley. Our applicators cover Nethercraigs.

Do I have to be there?

It depends on the job. Inside work needs someone to give us access.

Is it possible to paint over sand mastic?

Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.

Is it possible to take out silicone and use sand mastic instead?

Normally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.

How the visit works

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. 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 Nethercraigs, 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. We look at the surrounds with you and agree the joints to renew.
  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.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Let us know about parking restrictions

What the job involves on each surface

Sash and case windows

Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.

Brick reveals

Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

Why act early in Nethercraigs

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Private landlords in Nethercraigs 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.

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Planning or listed building consent (your local planning authority decides)
  • Damaged stone surrounds
  • Putty and glazing repairs

If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Where we work in Nethercraigs

  • Sash and case windows
  • Period & listed homes
  • Tenement windows
  • Timber door frames
  • Brick reveals
  • Stone surrounds

Signs you need sand mastic in Nethercraigs

Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they generally need raking out.

The most common problems we see are:

  • Crumbling sand mastic round a window
  • Modern sealant on a period surround
  • Open joints round the window box
  • Old cement repairs round a window that have failed

Letting a property close to Corkerhill station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Questions to ask before booking

  • How long the guarantee is
  • What happens if they find a problem under the old sealant
  • Whether you can choose the colour
  • How long to leave it before use

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Inspect the joints round the windows every year or so
  • Have rotten timber repaired before new mastic goes in
  • Make sure water runs off the sill
  • Ask the planning authority about consent for listed or conservation-area homes

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

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Sand mastic in Nethercraigs: local notes

Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Nethercraigs 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.

In the older streets around St James' (Pollok) Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Lourdes Secondary School, its window and door frames need their mastic kept sound, just like a home’s.
