About our sand mastic in Levenwick
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, tenement windows and sash and case windows, and common reasons people get in touch are mastic that needs renewing before redecorating and open joints round the window box.
Outdoor sealant needs a dry surface, so window work around Levenwick is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
You get a one-year guarantee, the same in Levenwick as everywhere else we work.

How the job changes by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sand mastic in Levenwick: local notes
Levenwick is close to 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.
For jobs in and around Levenwick, choosing the right material for each joint is as important as a tidy finish.
Levenwick is in the Shetland Islands. Every kind of property in Levenwick can book us for sand mastic. The work is guaranteed for a year. Levenwick is one of 63 towns and villages in the Shetland Islands we cover.
Work in ZE2 is quoted and booked the same way as anywhere else. You will find streets such as Staneybrake and South Punds Park, and we cover them all. If you are just outside Levenwick, we cover Bigton (2 miles west), Hoswick (2 miles north), Sandwick (2 miles north-east), South Scousburgh (3 miles south-west) and Boddam (3 miles south).

Why deal with it now?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Levenwick, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Levenwick questions
Is sand mastic in a coastal place like Levenwick any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will you come out to Levenwick?
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. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
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.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
What guarantee comes with the work?
Our 12-month guarantee applies on every job.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
