Sand mastic for Oxton homes and businesses

Sand mastic for homes and businesses in Oxton

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with cracked mastic round a front door frame and window mastic to renew ahead of painting, we can help, whatever the surface.

Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens on the day

We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Advice

Surface by surface

Stone surrounds

Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.

Timber door frames

Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.

Common problems we fix in Oxton

Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.

Keep an eye out for these signs:

  • Patchy fillers round a sash window
  • Gaps where the frame meets the masonry
  • Crumbling sand mastic round a window
  • Window mastic to renew ahead of painting

Around Oxton, as everywhere, sand mastic is only as good as the preparation behind it.

DIY sealant or a professional job?

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, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Oxton: your questions answered

Is sand mastic in Oxton guaranteed?

All our work, in Oxton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Can you do sand mastic in Oxton?

Yes, Oxton is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.

How long does the job take?

It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.

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

Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.

Can I do it myself?

You can, for simple jobs. 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.

Can you match the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Is sand mastic better than silicone for my windows?

It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.

Aftercare tips

So the new joints stay in good condition:

  • Leave the new mastic unpainted
  • Avoid patching sand mastic with silicone
  • Keep sills and gutters clear so water drains away
  • Avoid heavy scraping on the mastic joint

Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.

Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Oxton homes and the weather

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

For jobs in and around Oxton, choosing the right material for each joint is as important as a tidy finish.
