About our sand mastic in Wasbister

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with old cement repairs round a window that have failed and tired mastic found when preparing windows for paint, across timber door frames, brick reveals and period & listed homes.

Mastic can only go onto a dry joint, so outside work in Wasbister depends on the weather. Tell us about access to all the windows and doors, upstairs included.

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.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

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

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Outdoor work around Wasbister depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.

Advice

Sand mastic in Wasbister: local notes

Wasbister is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so give us as much notice as you can.

Historic houses such as Skaill House, about 3.6 miles north-west, show how far back building around Wasbister goes. In and around Wasbister, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Wasbister is about 11 miles west of Kirkwall, in the Orkney Islands. Homes, rented property, offices and hotels in Wasbister is covered for sand mastic. The work is guaranteed for a year. Wasbister is one of 51 places in the Orkney Islands where we work.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Plan mastic work ahead of painting
  • Leave the new mastic unpainted
  • Don’t run silicone over sand mastic
  • Ask a joiner to look at soft timber first

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

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

Your questions about sand mastic in Wasbister

Does living near the coast affect sand mastic in Wasbister?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Do you cover smaller places like Wasbister?

Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you work for landlords and businesses?

Yes. As well as householders, we work for landlords, agents, businesses and hotels across the Orkney Islands.

Is consent needed for window work on a listed home?

Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.

What is sand mastic?

Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Why act early in Wasbister

New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
