Need sand mastic in Holy Corner?

Sand mastic for homes and businesses in Holy Corner

We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on brick reveals, stone surrounds and tenement windows, and common reasons people get in touch are window mastic to renew ahead of painting and crumbling sand mastic round a window.

In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Holy Corner.

You get a 12-month guarantee, the same in Holy Corner as everywhere else we work.

Different surfaces, different methods

Period and listed homes

Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

What sand mastic looks like in Holy Corner

Holy Corner is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.

If you live in an older home near North Morningside Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Haymarket station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Holy Corner is about 1 mile south of Edinburgh, in Edinburgh. Across the EH10 area, we can carry out sand mastic at your property. Holy Corner is one of 175 towns and villages in Edinburgh we cover for sand mastic.

Work in EH10, EH11 and EH9 is quoted and booked the same way as anywhere else. If you need sand mastic at a property on Eden Lane, Spylaw Road and Canaan Lane or a nearby road, we can help. Close by, we work in Burghmuirhead (1 mile south), Greenhill (1 mile east), Church Hill (1 mile south), Merchiston (1 mile north) and Bruntsfield (1 mile north-east). We also work in nearby towns such as Leith (4 miles north-east), Bonnington (3 miles north-east), North Leith (3 miles north), Queensferry (8 miles north-west), Timber Bush (3 miles north-east) and Lochend (3 miles north-east).

What we do, step by step

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a single window, longer for several. For a tenement in Holy Corner, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.

  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. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
  • Tell us if parking is tricky

Landlord and commercial work in Holy Corner

Landlords and agents in Holy Corner can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.

For anyone letting property in or around Holy Corner, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

FAQs for Holy Corner

How do repairs to the shared parts of a tenement in Holy Corner get organised?

Shared parts of a tenement, such as the roof and outside walls, are usually 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.

I let a flat near Haymarket station. Can you help?

Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.

When will the new mastic be hard?

The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.

Where do you work from?

We are based in Crawley, and we cover South East England, London and all of Scotland.

Do you work in Holy Corner?

Yes. We work in Holy Corner and the rest of Edinburgh, as part of our work across South East England, London and Scotland. For a quote, drop us a line at info@mrmastic.co.uk.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Which is right for my windows, sand mastic or modern sealant?

We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Leave it or put it right?

Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a tenement flat in Holy Corner, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

How to look after the new joints

After the cure time, these simple habits help:

  • Plan mastic work ahead of painting
  • Check with your local planning authority if your home is listed
  • Inspect the joints round the windows every year or so
  • Have rotten timber repaired before new mastic goes in

Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.

An open joint round the box lets weather through. Left, the gap tends to get bigger.

What we’re called out for in Holy Corner

Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they generally need raking out.

Most people get in touch when they notice one of these:

  • Window mastic to renew ahead of painting
  • A silicone bead on a sash window that spoils the look
  • Wind and rain getting in round a sash window
  • Cracked mastic round a front door frame

If you look after a building such as Iain Tomlin School of Music, its window and door frames need their mastic kept sound, just like a home’s.

Questions to ask before you book

  • How the colour is chosen
  • Which sealant they’ll use, and why
  • What happens if they find a problem under the old sealant
  • How much experience the applicator has
