Trusted sand mastic in Auldhouse

Sand mastic in Auldhouse, done properly

Across Auldhouse, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you’re dealing with mastic worn away on windows facing the weather and cement or filler used on old window joints that has cracked, we can help, whatever the surface.

In and around a place like Auldhouse, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

There’s a 12-month guarantee on every job, large or small.

What we are called out for in Auldhouse

Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.

Common reasons people contact us include:

  • Draughty sash windows at the surround
  • Mastic worn away on windows facing the weather
  • Crumbling sand mastic round a window
  • A silicone bead on a sash window that spoils the look

For landlords with property near East Kilbride station, any sash windows need sound mastic to keep draughts and rain out.

Questions to ask before booking

  • How the surfaces are prepared before sealing
  • When the joint can take water or movement
  • Who does the work, and how experienced they are
  • What guarantee comes with the work

Choosing a sealant specialist

Common questions in Auldhouse

Do you cover smaller places like Auldhouse?

Yes, Auldhouse is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near East Kilbride 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.

Can sand mastic be painted?

Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will advise.

How much does sand mastic cost in Auldhouse?

It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk and let us know what needs doing and where.

Can you work on commercial sites?

Yes. We can plan bigger jobs in stages.

What’s sand mastic made of?

Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.

Can I choose the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

When will the new mastic be hard?

It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.

DIY versus a professional finish

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Aftercare tips

So the new joints stay in good condition:

  • Ask us before painting near the mastic
  • Get any rot dealt with first
  • Take care around the mastic when scraping paint
  • Make sure water runs off the sill

Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

What happens if it’s left?

Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In an older home around Auldhouse, damp from a failed joint can get into timber and plaster.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

What you get with us

  • We never seal over old sealant
  • Domestic, commercial and hotel work
  • Tidy, careful work
  • Over 20 years’ experience

Windows and doors in Auldhouse

Many older homes in Scotland have sash and case windows, 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 look after a building such as Duncanrig Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.
