How we handle sand mastic in Glencoe

Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. Typical jobs include gaps round a timber door in stone or brick and old sand mastic that has cracked, crumbled or fallen out, across tenement windows, timber door frames and sash and case windows.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.

Our work is backed for twelve months.

Questions from Glencoe

Will you come out to Glencoe?

Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is Glencoe in your area for sand mastic?

Yes, Glencoe is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

What information do you need?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.

Is the work guaranteed?

Every job comes with our one-year guarantee.

What does sand mastic cost?

Every job is different, so each one gets its own quote. To get one, send an email to info@mrmastic.co.uk and tell us what needs doing and where.

Do you work for landlords and businesses?

Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.

Can you replace silicone on a period window with sand mastic?

Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.

When will the new mastic be hard?

The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.

When to call us in Glencoe

Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

Any of these means the joints need attention:

  • Mastic dropping out of the joint
  • Gaps where the frame meets the masonry
  • Cement or filler used on old window joints that has cracked
  • Wind and rain getting in round a sash window

If you live in an older home near Episcopal Church Of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Questions to ask before booking

  • What the quote includes, VAT included or not
  • Which colour the sealant will be
  • What the cure time is
  • How long the guarantee is

Our hiring checklist

The process

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. For a place like Glencoe, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Advice

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Ask us before painting near the mastic
  • Plan mastic work ahead of painting
  • Avoid patching sand mastic with silicone
  • Have rotten timber repaired before new mastic goes in

Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.

Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, 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.

What the job involves on each surface

Period and listed homes

Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.

Stone surrounds

Sand mastic sits naturally against stone. The finish blends with the masonry.

What sand mastic looks like in Glencoe

Glencoe is within about 1 mile of 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. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.

Around Glencoe, as everywhere, sand mastic is only as good as the preparation behind it.
