Can I do it myself?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

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. Everything old must be removed first.

About our sand mastic in Morningside

On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we will explain which is best for yours. We work on brick reveals, stone surrounds and sash and case windows, and people most often call us about gaps where the frame meets the masonry and cracked mastic round a front door frame.

Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about sand mastic in Morningside

Is Morningside in your area for sand mastic?

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

Do you work for landlords with property near Wishaw station?

Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Do you guarantee sand mastic work?

There’s a 12-month guarantee on every job.

What exactly is sand mastic?

It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.

Can old silicone round a sash window be swapped for sand mastic?

Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.

Can sand mastic be painted?

Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll advise.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme.

What happens if it’s left?

A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In an older home around Morningside, damp from a failed joint can get into timber and plaster.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What we do, step by step

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Around Morningside, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can
  • Keep children and pets away from the work area

  • Decayed frames that need repair
  • Damaged stone surrounds
  • Decisions on consent for listed homes

If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

What we seal

  • Tenement windows
  • Brick reveals

What the job involves on each surface

Timber door frames

Round a period front door, sand mastic gives the right look.

Period and listed homes

Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.

Do you need sand mastic in Morningside?

Timber frames move with the seasons. That movement opens up the mastic joint over time.

It’s worth asking for a quote if you see:

  • Old sand mastic that has cracked, crumbled or fallen out
  • Modern sealant on a period surround
  • Cement or filler used on old window joints that has cracked
  • Mastic that needs renewing before redecorating

If you let a flat or house near Wishaw station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Choosing a sealant specialist

Morningside homes and the weather

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Cambusnethan House (about 3.4 miles south-west) nearby, there’s older building stock in the area around Morningside 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.

If you live in an older home near Coltness Memorial Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Coltness High School, its window and door frames need their mastic kept sound, just like a home’s.
