Sand mastic near Blackford

About our sand mastic in Blackford

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have weathered mastic on the most exposed windows and old sand mastic that has cracked, crumbled or fallen out, we can help, whatever the surface.

Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.

Your job is guaranteed for a year, as with all our work.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What we do, step by step

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several. Inside a flat in Blackford, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.

  1. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Move anything stored near the joints
  • For business premises, tell us about site rules or sign-in
  • Tell us about any previous sealing or DIY attempts

Advice

Landlords, agents and businesses in Blackford

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Landlords and agents in Blackford can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Windows and doors in Blackford

Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

For an older house near a landmark such as Reid Memorial Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Edinburgh Waverley station, any sash windows need sound mastic to keep draughts and rain out.

What we’re called out for in Blackford

Timber frames move with the seasons. The movement cracks the mastic over time.

Look out for any of the following:

  • Gaps where the frame meets the masonry
  • Cracked mastic round a front door frame
  • Draughty sash windows at the surround
  • Silicone on a period window that looks wrong

Managing a site like St Crispin's School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Blackford questions

Can you help a landlord with a rental near Edinburgh Waverley station?

Yes. We work for letting agents and landlords as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.

How is work on the outside of a tenement in Blackford generally arranged?

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. Your title deeds will say who owns the windows.

Will there be a smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

What exactly is sand mastic?

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

Will it make a mess?

We keep the work tidy. We protect what’s around the joints.

When will the new mastic be hard?

It takes a while. The skin forms first, and the full set comes later, and we will tell you what to expect.

Do you offer different sealant colours?

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before any work starts.

Are you fully insured?

Yes. We are fully insured.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Ask a joiner to look at soft timber first
  • Inspect the joints round the windows every year or so
  • Find out about consent before window work on a listed home
  • Leave the new mastic unpainted

Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.

Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

What affects the cost of sand mastic

The quote reflects the job in front of us. We look at:

  • Mould in or behind the old joints
  • The amount of work
  • Which sealant suits the joint
  • Whether the work is at height

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

What to tell us for a quote

You don’t need to know the technical terms. It helps if you can tell us:

  • Any access issues, like height or stairs
  • Pictures of the joints, sent by email
  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before
