Sand mastic in Cairns

What we’re called out for in Cairns

Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.

The most common problems we see are:

  • Draughty sash windows at the surround
  • Weathered mastic on the most exposed windows
  • Mastic dropping out of the joint
  • Gaps between timber frames and stone or brick

Letting a property close to Kirkhill station? Then any sash windows need sound mastic to keep draughts and rain out.

10 questions to ask before booking

Sand mastic in Cairns, done properly

Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on tenement windows, stone surrounds and period & listed homes, and common reasons people get in touch are gaps where the frame meets the masonry and patchy fillers round a sash window.

Outdoor sealant needs a dry surface, so window work around Cairns is planned around the weather. Let us know about access to every frame, including any upstairs.

You get a one-year guarantee, the same in Cairns as everywhere else we work.

Different surfaces, different methods

Stone surrounds

We take care not to mark the stone while raking out the old mastic.

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

Why deal with it now?

Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. 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.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Why book with us

  • Old sealant always removed completely
  • Experience in homes, commercial sites and hotels
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Quality sealants from Arbo and Everbuild

Common questions in Cairns

Can you do sand mastic in Cairns?

Yes. Our work covers the whole of Scotland, and Cairns is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.

I let a flat near Kirkhill station. Can you help?

Yes. We work for landlords and agents as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.

Do you do commercial work?

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

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Is sand mastic better than silicone for my windows?

Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant.

Is it OK to seal over old sealant?

No. The old sealant always comes out first.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

How it works

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. For a place like Cairns, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. First we agree which joints need doing.
  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. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive

For landlords and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Aftercare tips

Aftercare is simple:

  • Take care around the mastic when scraping paint
  • Look over the window mastic once a year
  • Keep modern sealant off the mastic
  • Ask us before painting near the mastic

When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

What sand mastic looks like in Cairns

Historic houses like Provand's Lordship (about 4.8 miles north-west) are a reminder that the area around Cairns has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

Managing a site like West Coats Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Cambuslang Baptist Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Cairns is about 1 mile south-west of Cambuslang, in South Lanarkshire. We provide sand mastic to homes and businesses in Cairns, as part of our work across South Lanarkshire. Our area takes in 139 places across South Lanarkshire, large and small. We also work in Glasgow, about 6 miles from Cairns.

What affects the cost of sand mastic

Jobs vary more than people expect. What affects the quote:

  • Which sealant suits the joint
  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How many areas need sealing

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What to tell us for a quote

When you contact us, it’s useful to know:

  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • The rough size of the job

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, email us at info@mrmastic.co.uk.
