Sand mastic in Sighthill

Sand mastic in Sighthill

Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on stone surrounds, tenement windows and brick reveals, and common reasons people get in touch are old cement repairs round a window that have failed and window mastic to renew ahead of painting.

Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Sighthill, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.

All our work is covered by a one-year guarantee, wherever you are in Edinburgh.

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Common problems we fix in Sighthill

Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.

People generally contact us after spotting something like this:

  • Failed mastic on an exposed elevation
  • Cement or filler used on old window joints that has cracked
  • Gaps where the frame meets the masonry
  • Silicone on a period window that looks wrong

Questions from Sighthill

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

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. Windows often belong to the individual flat, but it’s worth checking your deeds.

Can you do sand mastic in Sighthill?

Yes. Our work covers the whole of Scotland, and Sighthill is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Are you insured?

Yes. We’re fully insured.

How much does sand mastic cost in Sighthill?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Can new sealant go over the old?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Where is Mr Mastic based?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Is it possible to take out silicone and use sand mastic instead?

Normally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.

What we do, step by step

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints. Parking in city streets around Sighthill can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.

  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. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
  • Keep pets and children clear of the area while we work

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Ask us before painting near the mastic
  • Look over the window mastic once a year
  • Don’t run silicone over sand mastic
  • Plan mastic work ahead of painting

Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

How the job changes by surface

Brick reveals

An open joint at a brick reveal lets weather in. New mastic seals the gap.

Stone surrounds

Sand mastic sits naturally against stone. It finishes to look like part of the surround.

Sighthill homes and the weather

Historic houses like Caroline Park (about 4.5 miles north-east) are a reminder that the area around Sighthill has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, often through a property factor. Windows generally belong to the flat, but the title deeds have the final say.

Caroline Park, about 4.5 miles north-east, is one of the historic houses in the wider area around Sighthill, and older homes nearby need a sealant that suits their walls.

Leave it or put it right?

New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Wind-driven rain gets into any failed joint on the outside of a city building, and in Sighthill, damp can spread through stone and plaster before anyone sees it.

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
