Sand mastic in Kingsknowe

Sand mastic in Kingsknowe, done properly

Across Kingsknowe, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on brick reveals, tenement windows and stone surrounds, and the jobs we see most are mastic that needs renewing before redecorating and modern sealant on a period surround.

Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.

Big or small, it’s backed by our one-year guarantee in Kingsknowe and across Edinburgh.

Why act early in Kingsknowe

If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. For landlords in Kingsknowe, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.

The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

How the job changes by surface

Timber door frames

Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.

Stone surrounds

Stone surrounds suit sand mastic well. The finish blends with the masonry.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Renew mastic before redecorating the windows
  • Inspect the joints round the windows every year or so
  • Don’t paint over the new mastic
  • Keep sills and gutters clear so water drains away

Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.

Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

What we can’t put right

To be straight with you, there are a few things sealant won’t fix:

  • Decayed frames that need repair
  • Putty and glazing repairs
  • Planning or listed building consent (your local planning authority decides)

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Kingsknowe questions

Do you work for landlords with property near Kingsknowe station?

Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.

Can you do sand mastic in Kingsknowe?

Yes, Kingsknowe is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Where is Mr Mastic based?

We’re a Crawley-based firm. Our area covers South East England, London and Scotland.

Do you guarantee sand mastic work?

Our one-year guarantee covers every job, sand mastic included.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

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

Generally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Sand mastic in Kingsknowe: local notes

Many older homes in Scotland have sash and case windows, often pointed into the wall with 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. Who owns the windows depends on the title deeds.

Rented homes near Kingsknowe station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as Merchiston Castle School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Whitefoord House, about 4.1 miles north-east, is one of the historic houses in the wider area around Kingsknowe, and older homes nearby need a sealant that suits their walls.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows. Parking in city streets around Kingsknowe can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The mastic is finished to sit tidily against the stone or brick.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Let us know about earlier repairs to the joints
  • Where the joints are inside, avoid wetting them before we arrive
