Sand mastic in Highland: how it works

We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on stone surrounds, sash and case windows and period & listed homes, and the jobs we see most are failed mastic on an exposed elevation and cracked mastic round a front door frame.

You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases.

We check each window surround and the condition of the joint.
We rake out the old mastic and clean the joint.

Local landmarks in Inverness

In Inverness, that means homes and buildings near Inverness, Cavell Gardens and Maple Court Hotel. Inverness’s nearest station is Inverness station, roughly 0.7 miles north. Nearby you’ll also find Inverness Castle (0.5 miles north) and Inverness Museum and Art Gallery (0.5 miles north). For a walk, there’s Tomnahurich.

Frames and weather across Highland

Homes across Highland range from period properties with timber or sash windows to new builds with uPVC. Exposed walls are where window sealant usually fails first, wherever they are in Highland.

Our work covers the whole of Scotland, Highland included. Journeys are planned ahead, and outside jobs are booked around the forecast. Coastal guest houses and holiday lets in Highland can see heavy use in busy months, which is hard on sealant and grout, and the weather is hard on the outside too.

Inverness: If you look after a building such as Inverness High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Inverness station? Then any sash windows need sound mastic to keep draughts and rain out.

Landlords, agents and businesses in Highland

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Landlords and letting agents in Highland can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

Surface by surface

Brick reveals

Loose mastic comes out and deep gaps are packed before pointing.

Timber door frames

Sand mastic is used round timber door frames too. The method is the same as for windows.

When it is not the sealant

In fairness, there are a few things sealant won’t fix:

Whether work needs listed building consent
Decayed frames that need repair
Sashes that need overhauling

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

Go gently near the mastic when preparing windows
Ask a joiner to look at soft timber first
Leave the new mastic unpainted
Keep modern sealant off the mastic

Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.

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.

Highland questions

Should I check with the council before work on a listed or conservation-area home?

Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Do you come to Highland?

Yes, we do. Our applicators work in Highland.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us and we’re fully insured.

Will the old sealant be removed?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What’s sand mastic made of?

A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.

Can you seal over the old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
