Sand mastic for Muirhouse homes and businesses

DIY versus a professional finish

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.

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.

Sand mastic in Muirhouse, done properly

Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on stone surrounds, tenement windows and brick reveals, and common reasons people get in touch are modern sealant on a period surround and draughty sash windows at the surround.

Muirhouse is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.

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

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Inside a flat in Muirhouse, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any parking rules near the property
  • Keep children and pets away from the work area

Windows and doors in Muirhouse

Muirhouse is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

Managing a site like Craigroyston Community High School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Haymarket station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Muirhouse is about 3 miles north-west of Edinburgh, in Edinburgh. Whether you are in the middle of Muirhouse or further out, sand mastic is available for homes and businesses alike, from flats and houses to offices and hotels. We cover 175 towns and villages across Edinburgh.

10 questions to ask before booking

Your questions about sand mastic in Muirhouse

Can you help a landlord with a rental near Haymarket station?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.

Who arranges sealant work on the shared parts of a tenement in Muirhouse?

It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.

Where is Mr Mastic based?

We work from Crawley. We cover Muirhouse and the rest of Edinburgh, along with the rest of our area.

How do I get a quote for sand mastic in Muirhouse?

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.

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

Yes, we do this often. All the old silicone is removed first so the mastic beds in well.

Do I need permission for sand mastic on a listed building?

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

How we quote for sand mastic

For a quick quote, just ask. What matters most is:

  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved
  • Any mould that needs treating
  • Working hours on commercial sites

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

What we need to know

When you contact us, it’s useful to know:

  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking

Why act early in Muirhouse

An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a tenement flat in Muirhouse, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Landlord and commercial work in Muirhouse

If you manage several properties in or around Muirhouse, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check the mastic when you check the paintwork
  • Don’t run silicone over sand mastic
  • Avoid heavy scraping on the mastic joint
  • Find out about consent before window work on a listed home

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.

Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
