Our sand mastic service in Na h-Eileanan Siar

A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for window mastic to renew ahead of painting and gaps between timber frames and stone or brick, on sash and case windows, brick reveals and timber door frames.

We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a single window, longer for several.

First we agree which joints need doing.
Old mastic and any loose material are raked out.
We pack any deep voids first.
We apply the mastic by hand and shape it.
We dress the finish so it sits neatly against the masonry.

How we quote

Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

What you get with us

Full insurance on every job
Any old sealant cut out fully, not covered over
Trusted Arbo and Everbuild sealants

Sand mastic across Na h-Eileanan Siar: local notes

From Stornoway, Tarbert and Plasterfield to its smaller places, Na h-Eileanan Siar has windows and doors of every age and material. Each needs the right sealant, and every joint wears out eventually.

We work across all of Scotland, from the cities to the islands, and Na h-Eileanan Siar is part of that. Journeys are planned ahead, and outside jobs are booked around the forecast. Along the coast in Na h-Eileanan Siar, window and wall joints facing the sea take the brunt of the weather, so they’re often the first to fail. The right product and careful preparation help it last.

Stornoway: For jobs in and around Stornoway, choosing the right material for each joint is as important as a tidy finish. In and around Stornoway, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes.

What your quote should include

How hidden problems are handled
Which sealant they’ll use, and why
Whether they seal over old material or remove it
What guarantee comes with the work

When it isn’t the sealant

Before booking, it’s worth knowing the limits too:

Putty and glazing repairs
Rotten sashes, sills or window boxes (a joiner’s job)
Sashes that rattle, stick or won’t open

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Different surfaces, different methods

Tenement and terrace windows

Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too across Na h-Eileanan Siar. We can quote a run of properties together, and we’re fully insured for the work.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Na h-Eileanan Siar questions

Can old silicone round a sash window be swapped for sand mastic?

Generally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.

Do I need permission for sand mastic on a listed building?

Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Do you have insurance?

Yes. We are fully insured, with over 20 years’ experience in sealant work.

How much does sand mastic cost in Na h-Eileanan Siar?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
